The RSPB Big Garden Birdwatch 2024

For the past 45 years, the RSPB has been running one of the largest citizen science projects in the world, the Big Garden Birdwatch. Every January more than half a million people take to their gardens, parks and balconies to count the birds they see. This huge dataset has allowed the RSPB to create a comprehensive picture of how our local birds are faring, and to examine changes in both abundance and distribution over time.

This year’s Big Garden Birdwatch will take place from the 26th to 28th January and anyone can sign up to take part – all it takes is an hour of your time to record the birds you see in your area and send these results to the RSPB. They will then collate all of the data and publish the results in spring.

How to take part in the Big Garden Birdwatch

- Sign up on the RSPB website
- Find a good spot to watch the birds in your garden or a local park and choose an hour between between Friday 26th and Sunday 28th January.
- Have fun identifying the species visiting your garden during that hour and count the maximum number of each species you see at any one time. For example, if you see a group of three House Sparrows together and after that another one, the number to submit is three. This method means it is less likely you will count the same birds more than once and makes data analysis easier. Make a note of any other wildlife that you spot as well.
- Submit your results on the Big Garden Birdwatch website. Even if you don’t see anything, that’s still useful information. (If you can’t submit your results online, you can print off the form from the free guide and send it by post).
- Join in the conversation on RSPB social channels throughout the weekend to see what other nature lovers are spotting across the UK and upload your own pictures and comments using #BigGardenBirdWatch
- Look out for the results in April and take pride in having contributed data from your patch.

What did we learn in the 2023 Big Garden Birdwatch?

In 2023, over half a million people took part in the Big Garden Birdwatch, submitting records of more than 9.1 million birds. The most frequently reported species was the House Sparrow which received 1.4 million sightings, however counts of this bird have notably decreased by 57% when compared to the first Birdwatch in 1979. The second and third spots were held by Blue Tits and Starlings respectively.

Last year’s results highlighted the vulnerability of some of our smaller garden birds and the environments they live in. Long-tailed Tit sightings increased by 39% in 2023, however they are very susceptible to harsh weather conditions and as a result of this, population numbers have fluctuated since the Big Garden Birdwatch began. Meanwhile, Greenfinches and Chaffinches continued to be affected by a disease known as Trichomonosis, which has led to a 34% decline in UK Chaffinch populations and 65% decline in Greenfinches over the last decade.
It is hoped that this year’s Birdwatch will help to give a better picture of how these population are faring a year on.

How can I encourage more birds and other wildlife to my garden?

Participating in the Big Garden Birdwatch is the perfect opportunity to observe how wildlife is using your garden and to give you some insights into how you could make your outdoor space even more attractive to wildlife.

Improving your garden for wildlife can be as simple as leaving a patch of long grass; providing native trees or plants that are good for pollinators such as lavender, buddleja and verbena; or leaving a woodpile for insects to shelter in. You can also supply nest boxes for birds, bat boxes for summer roosting bats, access panels and shelters for hedgehogs, shelter for frogs and toads, and of course bird feeders, which will bring a multitude of species to your garden.

Policy

A final vote on the Nature Restoration Law (NRL) will be taking place in the European Parliament early this year. This regulation aims to halt and reverse biodiversity loss in Europe by implementing restoration measures on a minimum of 20% of land and marine areas by 2030. Specific targets to rewet peatlands and increase pollinator populations are also included in the law. Financial support for the NRL will come from funds provided by the EU’s Common Agricultural Policy.

Research

New research conducted at the Quinney College of Natural Resources has shown that Barnacle Geese have a bigger impact on Svalbard’s ecosystem than Reindeer, and that their impact is increasing over time. Since the Arctic climate is shifting faster than other places under global climate change, and Svalbard is one of the most rapidly warming regions on Earth, understanding the effects of these herbivore populations on ecosystem functioning is important and will allow scientists to predict how this region is likely to be affected in the future.

It is no secret that pesticides are harmful to honey bees. However, new research from the University of Illinois has provided more information on how such pesticides impact the sense of smell in bees with consequences for social signalling such as the detection of colony pheromones. This research has also shown how fungicides, previously thought to be harmless to bees, can be toxic, especially when used in combination with insecticides and adjuvants (chemicals that help the insecticide to stick to the target plant).

Flesh-footed Shearwater by patrickkavanagh via Flickr.

A researcher at the Natural History Museum, London, is using machine learning to find out more about the types of plastic that seabirds are feeding to their young. Birds such as the Flesh-footed Shearwater often mistake small pieces of plastic for food, but it isn’t currently known whether they target certain types of plastic based on appearance. This information would help in identifying the types of plastic that need to be removed from the ocean most urgently.

Since 2009, the Cambridge Conservation Initiative has conducted a horizon scan each year which aims to predict which threats, changes and technologies will be most significant over the next twelve months. This year, the final list included fifteen topics including several relating to sustainable energy, declining invertebrate populations and changing marine ecosystems. The list of issues, as in many of the recent years, reflects both anthropogenic impacts on biodiversity alongside the technological advances designed to deal with those impacts.

Climate

Following a year of unprecedented global temperatures, scientists are now trying to understand what this can tell us about climate change and the rate at which it is accelerating. Although one exceptional year would not be enough to suggest the inaccuracy of current climate prediction models, researchers are now trying to find out whether something unexpected may be occurring due to the interactions between two or more climate influences.

A recent audit by the National Trust has found that the weather is “causing chaos for UK flora and fauna”. A lack of reliable seasonal patterns, accompanied by extreme weather events, droughts and floods are putting a huge amount of stress on plants and animals. The National Trust say that more action is urgently required from politicians to ensure that tackling the associated biodiversity and climate crises is a priority, particularly as we enter an election year.

Author Q&A with Michelle Sole: Antarctica: A Bird’s-eye View

This stunning photographic book, written in collaboration with penguinologist Dr Tom Hart, offers a unique view of Antarctica from above and captures the wonders of this magical place, from vast icebergs to penguin colonies in their thousands. Each chapter includes an array of incredible captioned images, taken from both land and air, and describes the resident wildlife and conservation efforts in this remote area.

Michelle Sole grew up living between the rolling hills of England and the alpine wilds of Andorra. In 2011 she moved to South Africa, spending the following six years working as a Safari Guide and nurturing her passion for photography, before becoming a photography guide on expedition ships in Antarctica and the Arctic where she continues to challenge her photography in extreme conditions today. Michelle’s thrill for adventure, nature and the outdoors is evident throughout her photography and writing, and since her career began her work has been published worldwide in papers including Africa Geographic and The Daily Mail.

Michelle recently took the time out of her Antarctica expedition to Snow Hill Island to talk to us about the inspiration behind the book, the challenges she faced photographing such a challenging environment and more.

You began getting into photography when you moved to South Africa in
2011. What encouraged you to take the leap from the sunny African
plains to Antarctica, and how does photography compare from one
environment to another?

I worked as safari guide in South Africa and one of my guests just so
happened to be the president of a polar expedition company and he offered
me a job! The opportunity was too good to pass up and in 2017 I started
working as a photography guide in Antarctica and the Arctic regions.

The photography varies drastically between Africa and Antarctica. In Africa
you are often hiding from the sun and in Antarctica the elements are against
you. The light in Antarctica is a lot harsher than in Africa and photographing black and white penguins on bright white snow takes some practice.

What was it that inspired you to create this book and capture Antarctica
from the sky rather than focusing solely on more conventional, land-
based photography?

I was approached by Dr Tom Hart from Oxford University to collaborate and
make this book. Tom had over 40,000 drone images from penguin and seal
surveys. These are used to try and gather population trends across different
locations in Antarctica and the Southern Ocean. I had a similar number of
images from the ground and a collection from helicopters. The aerial shots really add a different dimension and together with the images from the ground tell a grander and more unique story of the landscapes and wildlife of this remarkable place.

Did you face any significant challenges that you had to overcome while
taking photographs in such a remote, harsh and often unpredictable
environment?

Yes! The weather in Antarctica can be brutal. Some days you are battered by
the winds and you can’t feel your finger tips, or you could be in a snow storm with snow collecting on the top of your camera as you shoot. I always carry a towel in my bag to protect my gear. Salt water takes a major toll on photographic equipment and throughout the years I’ve tried to salvage numerous cameras, sadly they didn’t all survive. On top of that, I am often photographing from an unsteady platform – a zodiac (a type of rigid inflatable boat) that I am driving on the ocean.

Were you concerned over any possible impacts on the wildlife
that you photographed even though you used drones to capture some images?

Special permission was given to the researchers from the Penguin Watch
team to fly drones for scientific purposes to conduct penguin and seal surveys. The drones were flown at a non disturbance height. This is evident in the aerial wildlife photographs by the behaviour of the animals – the seals continue to sleep and the penguins continue to walk on their highways without so much as looking at the drone.

I was really surprised to see such a wide variety of habitats and species
in your photographs as I, like many, often think of Antarctica and the
surrounding areas as enormous ice-shelves rather than steaming
volcanoes and vibrant pumice rocks. Was there anything that took you
by surprise while you were out taking photographs for this book?

At the time of putting together this book I had six years of experience in Antarctica, so I was familiar with many of the different landscapes. However, on my first trip to Antarctica, like many others visiting for the first time, I was taken aback by the variety of landscapes on the seventh continent. As a guide in this environment, this initial wonder and surprise is something that I see in other people experiencing this for the first time on nearly every trip.

Are you currently planning to undertake any other photography projects
next year that we can hear a sneak-preview about?

As I write this I am currently onboard an expedition ship south bound to the most northerly Emperor Penguin colony in the world –Snow Hill Island,
Antarctica. I also work in the Arctic each summer and spend a significant
amount of time out in Africa. Although I have no current plans to produce
books on these areas, my photography portfolio continues to grow.

Antarctica: A Bird’s-Eye View has been privately published by author Michelle Sole and is available at www.nhbs.com/Antarctica: A Bird’s-Eye View.

25% of profits from the sale of this book is donated to Penguin Watch.

Beavers will return to the Cairngorms after 400 years in a bid to boost biodiversity. The new population will be established by the Cairngorms National Park authority after being approved by NatureScot, Scotland’s nature agency. Up to 15 families of beavers will be released at sites along the upper River Spey. This catchment is an ideal location for beaver translocation and poses a low risk of beaver/human conflict, according to NatureScot.

The fight to save Red Squirrel populations continues to rage across the North of England. Retired police constable and firearms instructor, Ian Glendinning, monitors 2,000 acres of farmland in Northumberland and employs a range of techniques to keep the Grey Squirrels in check. Monitoring Northumberland’s Coquetdale, he has employed CCTV and traps that alert him via text and email when a squirrel is detected. Using this monitoring system, Glendinning has removed around 300 Grey Squirrels which has had a noticeable impact on the Red Squirrel population, allowing their population to increase from a dozen to more than 100 over the past four years.

Policy and diplomacy

Countries are set to commit to a major phasing down of fossil fuels over the coming decades, COP28 hosts expect. The United Arab Emirates, which is hosting the UN climate change conference in Dubai, has expressed “cautious optimism” regarding the commitment. Until COP26 in Glasglow in 2021, fossil fuels were rarely mentioned in these global gatherings. Even there, the only commitment was to phase down coal. While the pledge will not mean stopping the use of fossil fuels completely, it could signal a shift towards real progress on tackling climate change.

Carbon pricing could raise the money needed to tackle the climate crisis, the IMF has told COP28. The cash could be generated by putting a price on carbon emission and redirecting the trillions of dollars currently used to subsidise fossil fuels. Traditional carbon taxes have proven to be unpopular in a number of countries but Kristalina Georgieva, managing director of the IMF, has said that it would be possible to achieve similar outcomes by using a combination of regulation and reducing carbon subsidies. Studies have shown that developing countries will need more than $2 trillion a year to cut emissions and the IMF has calculated that direct and indirect subsidies for fossil fuels are in excess of more than $7 trillion.

Climate Crisis

Olive oil prices are surging due to droughts in Spain. Spain is the world’s biggest producer of olive oil, accounting for 70% of European Union consumption and 45% of global consumption. The standard assumption that one bad year for olive production would be followed by a good one is shifting in the face of rising temperatures due to climate change. Spain has seen multiple years of drought in a short time frame, and together with higher fuel, electricity and fertiliser costs, Spanish olive oil production has suffered as a result. The price of olive oil has skyrocketed in Spain with prices in the UK and Ireland set to experience a similar surge once costs feed through to the supply chain.

Methane could be released from the Deep Ocean due to climate change, scientists have warned. Scientists at Newcastle University have shown that frozen methane trapped under the ocean is vulnerable to melting and is consequently released into the oceans and the atmosphere. Methane is a potent greenhouse gas, and the published report in the journal Nature Geoscience warns that vast amounts of methane stored as marine methane under the ocean could be released into the atmosphere, with the potential for accelerating rises in atmospheric greenhouse gas concentrations.

Extinction

Plans to ‘de-extinct’ the dodo have been announced by geneticists. The audacious plan was announced by the US-based biotechnology company Colossal Biosciences which is researching methods to bring extinct species back from the dead. The company has entered a partnership with the Mauritian Wildlife Foundation (MWF) to find a suitable location for the reintroduction of the species. MWF approached Colossal Biosciences earlier this year about a partnership and has begun searching for the location that would pose the least threat to the survival of the dodo on the island. Colossal believes that the ‘de-extinction’ of the dodo would create ‘conservation optimism’; however, scientists have urged caution given how little is known about how the bird would interact with its environment. The full genome of the dodo has already been sequenced by Colossal. It hopes that it could then hybridise the dodo with closely related species like the extant Nicobar Pigeon, the bird’s closest living relative.

Science and research

Birds are being lured to their deaths by artificial lights in cities, according to researchers. Using weather radar data to map bird stopover density in the United States, scientists found that artificial light is a major indicator of where birds land. Light from cities lures birds into a trap where there is less suitable habitat, less food and an increased chance of collisions with buildings. Researchers suggest that more public awareness of bird migration habits and the impact of light pollution could help to alleviate the pressure on migratory bird populations. Forecasts can pinpoint the nights which are most important for reducing light pollution.

Biodiversity Net Gain: Key guidance and secondary legislation published

2024 is set to bring big changes to development law with Biodiversity Net Gain (BNG) measures becoming mandatory for most developments in England from 1st January. Small sites will not be subject to BNG laws until April 2024, while laws pertaining to Nationally Significant Infrastructure Projects (NSIPs) are expected to come into force in November 2025.

The Biodiversity Net Gain timeline to date

Following the Environment Act 2021 receiving royal assent in November 2021, provision was made for BNG to be introduced in England commencing in 2023. It was set out that gains could be delivered onsite, offsite or through the purchase of biodiversity credits.

In February 2023, Defra published its consultation response which provided more details on how BNG would be implemented, and suggested that the law would come into effect in November 2023. This has now been revised to January 2024.

At the end of September 2023, Defra and the Department for Levelling Up, Housing and Communities (DLUHC) published a timetable for the introduction of BNG. They also confirmed that it would only apply to new planning permission applications and not applied retrospectively to applications submitted prior to 1^st January 2024.

This week, on 29^th November, key guidance documents and secondary legislation were published by the Government.

Guidance documents

Step-by-step guidance has been provided for developers, land managers and local authorities which lead users through the BNG process.

Guidance for developers includes information on measuring the impact of a specific development on biodiversity, deciding how to achieve BNG, and ensuring that the 10% gain is maintained for at least 30 years.

Guidance for land managers looks at the options available for their land type and quantity, preparation and selling of biodiversity units, registering and recording the sale of the units to a developer, and the subsequent long-term management of the habitat.

Guidance for local authorities includes information on setting local policies to support biodiversity net gain, approving planning applications and biodiversity gain plans, reviewing the biodiversity gain plan, checking metric calculations and habitat surveys, checking developers selling excess on-site gains, checking the biodiversity gain sites register for off-site gains, monitoring BNG, and working with developers who wish to buy statutory biodiversity credits.

Secondary legislation

Secondary legislation are laws that add more detail to primary legislation, allowing them to be enacted and enforced. In the case of BNG, these laws will provide the practical details required for measures to be implemented under the primary legislation of the Environment Act 2021.

Statutory instruments (SIs) are the documents created that must be laid in Parliament before the law can be changed. There are six BNG statutory instruments that will need to be approved by Parliament before they can be brought into effect on 1^st January. These include:

The Biodiversity Gain (Town and Country Planning) (Consequential Amendments) Regulations 2023 – These regulations make amendments to the existing primary legislation on planning so that the BNG framework can be included.

The Biodiversity Gain Site Register (Financial Penalties and Fees) Regulations 2023 – This allows for fees to be incurred when registering land in the biodiversity gain register and financial penalties to be charged where incorrect information is provided.

The Biodiversity Gain Site Register Regulations 2023 – This sets out the details and eligibility criteria for the creation of a publicly available “biodiversity gain site register”. The register will be established and maintained by Natural England.

The Biodiversity Gain Requirements (Exemptions) Regulations 2023 – This sets out the categories of development that are exempt from creating biodiversity net gain.

The Biodiversity Gain Requirements (Irreplaceable Habitat) Regulations 2023 – This lists the habitats that are considered irreplaceable and for which the standard 10% requirement will not be applied.

The Biodiversity Gain (Town and Country Planning) (Modifications and Amendments) (England) Regulations 2024 – These regulations details how the BNG process will work within the existing planning application procedure. It also includes details of how appeals should be made.

The first two SIs were laid in Parliament on 30^th November and will shortly be published on the Government’s legislation website. The remaining four still require approval by Parliament, although draft versions can be viewed using the links above.

Next steps

In January 2024 BNG will become mandatory for new applications for planning permission, with the exclusion of small sites* where BNG will not need to be delivered until April 2024, and NSIPs which will be covered from November 2025.

Having lost nearly half of our biodiversity since the 1970s, the UK is one of the most nature-depleted countries; we are ranked in the worst 10% globally for biodiversity intactness. Overall, 41% of species in the UK have declined in the last 50 years, with 26% of mammals at risk of extinction. We’ve lost 97% of our meadows, 90% of our wetlands and 80% of lowland heathland.

A scheme where development will no longer lead to biodiversity loss, but instead to net gain, is a step in the right direction to preventing further loss and helping to begin repairing our degraded environment.

* (Small sites are defined as (i) For residential: where the number of dwellings to be provided is between one and nine inclusive on a site having an area of less than one hectare, or where the number of dwellings to be provided is not known, a site area of less than 0.5 hectares. (ii) For non-residential: where the floor space to be created is less than 1,000 square metres OR where the site area is less than one hectare.).

Climate Crisis

Plants may absorb more CO2 from human activities than previously thought, according to new research. More realistic modelling that considers critical physiological processes inside plants paints a more positive picture than previous predictions. The efficiency of carbon transport in plant leaves, the ability of plants to adjust to changes in temperatures, and how plants distribute nutrients in the canopy, often ignored in climate modelling, were examined in this study. Scientists stress that simply planting more trees is not a silver-bullet solution, but that the research does underline the importance of efforts to conserve existing vegetation.

Red alerts have been issued as Brazil suffers an unprecedented heatwave. Temperatures are likely to remain 5°C above average for longer than five days and could pose a serious danger to human health. Rio de Janeiro recorded 42.5°C, breaking November records, and due to high humidity felt like 58.5°C according to authorities. The heatwave has been attributed to a combination of the El Niño climate phenomenon and climate change. The human impact of such extremes is significant with “unbearable” temperatures leading to sleepless nights, exhaustion, illness and death.

Pollution

Most bathing spots in English rivers and lakes have unsafe pollution levels, according to a new report. The campaign group Surfers Against Sewage took a sample of popular swimming and water sports locations and found that 60% had unsafe levels of pollution. This year across the UK, untreated sewage was discharged 399,864 times into waterways, resulting in a reported 1,924 cases of illness. The report highlighted the case of a physics teacher from Exeter who contracted an incurable disease known as Ménierè’s disease after surfing at Saunton Sands in Devon.

The high court has ruled that Defra’s failure to protect and restore water bodies is ‘unlawful’. Fish Legal and Pickering Fishery Association took the government to court over its river basin management plan for the Costa Beck, a small river in Yorkshire. They argued that the Environment Agency had failed to follow through with proposed action against polluters. The judge accepted discharges of pollution were contributing to the poor condition of the river and that the government and Environment Agency had failed in their mandatory duty to put in place measures to restore rivers under the Water Framework Directive.

Extinction Risk

Blue Whales have returned to safe havens in the Indian Ocean where they were wiped out decades ago. Underwater recordings made by researchers in the Seychelles revealed that the whales spend months in the region, suggesting that they may be breeding there. The discovery has been hailed as a “conservation win” given the decimation of whale populations by commercial whaling. More than 300,000 Blue Whales were killed by whalers in the southern hemisphere with around 30,000 killed in a single year during the 1930’s. A crackdown on commercial whaling in the 1980’s brought the species back from the brink of extinction; however, Blue Whale numbers remain a fraction of what they once were before the development of industrial whaling operations in the 20th century.

New research has revealed that there is a significant threat of future waves of invasive species. Biological invasions can cause extinctions, spread diseases and cost trillions in damage and control. Researchers found that, on average, around 1% of all living organisms have been transported by humans somewhere in the world. The study indicates a huge potential for future biological invasions with an expected rise in associated socio-economic and environmental impacts.

A hedgehog fence in Dorset is helping to protect threatened seabird chicks. Little Terns are one of the most threatened seabirds in the UK and the RSPB’s Chesil Little Tern Recovery Project seeks to reverse its decline. Trail cameras had revealed that hedgehogs had been eating Little Tern eggs. Given the protected status of hedgehogs, the project worked with the charity Hedgehog Friendly Portland to design a hedgehog fence and implement diversionary feeding. At least 45 Little Terns successfully fledged at Chesil Beach in 2023, compared with just three in 2021.

The US will outline its nuclear fusion power strategy at COP28. John Kerry, the US Special Envoy on Climate Change, will set out the plan at the UN summit that will be held in Dubai from the 30th of November. The plan has been described as being the first international strategy for nuclear fusion power commercialisation. Nuclear fusion has long been looked at as a potentially limitless source of clean energy.

Extinction Risk

First images of a lost echidna species prove that it is not extinct. An expedition to the sacred Cyclops Mountains in Indonesia uncovered evidence of Attenborough’s Long-beaked Echidna. Echidnas are ancient egg-laying mammals thought to have emerged 200 million years ago when dinosaurs still roamed the earth. Until now, the only evidence for this particular species of echidna, named after Sir David Attenborough, was a museum specimen. Scientists hope that the discovery of living echidnas will help make the case for conservation efforts in the Cyclops Mountains. In addition to the echidna, new species of insects and frogs were discovered alongside healthy populations of birds of paradise and tree kangaroos.

Fewer than half of Bornean Sun Bears survive after release due to habitat loss and poaching, according to a recent study. Sun Bears are a keystone species in the jungles of South-East Asia, helping to sustain healthy forest ecosystems; however, fewer than 10,000 Sun Bears are thought to remain in the wild due to pressures from deforestation, habitat degradation and poaching. The Bornean Sun Bear Conservation Centre (BSBCC) looks after Sun Bears rescued from captivity and releases them back into the wild. A recent study has shown that many released Sun Bears die due to the dangers they encounter in the wild, including poaching, territorial disputes and starvation. A lack of familiarity with their new surroundings may also contribute to this high death toll despite the released bears being skilled climbers and foragers.

An ambitious project in the Fens seeks to reclaim thousands of acres for nature. The Great Fen Project, organised by Wildlife Trust conservationists, aims to purchase 9,000 acres of farmland around two Fenland nature reserves to allow water to return to the land. This will support the formation of water meadows, streams and pools which will encourage wetland species such as Bittern and Marsh Harrier. By rewetting fields, it also seeks to preserve peat and reduce carbon emissions. With a projected price tag of around £30 million, the project will be one of the most ambitious restoration projects in all of Europe.

Svalbard is letting nature take back one of its massive coal mines. The Svea mine in Svalbard, Norway, which produced 34 million metric tonnes of coal over its lifetime, is undergoing a significant natural restoration project. The restoration effort, costing approximately 1.6 billion Norwegian kroner (€1.35 million), aims to return the site to its natural state, allowing nature to reclaim the land. This move is part of Norway’s commitment to preserving the wilderness of Svalbard, as the region transitions away from the fossil fuel industry, closing coal mines and shifting towards tourism and scientific research.

Climate Crisis

Surges in jellyfish numbers in UK waters are an indication of warming oceans, according to the Marine Conservation Society. The number of jellyfish seen on UK beaches has increased by 32% in the past year. Warm water jellyfish such as the Crystal Jellyfish have been spotted following global ocean temperatures reaching a record high in August and marine heatwaves in June which caused UK sea temperatures to rise by 3–4°C. Experts have said that more research will be needed to determine the exact cause of the jellyfish blooms this year.

Global temperatures will reach the 1.5°C threshold this decade, according to a new report. In 2015, countries agreed to take measures to hold global temperatures to 1.5°C above pre-industrial levels as part of the Paris Climate Agreement. New research by a team of scientists from Columbia University and NASA suggests that this goal is already out of reach, which may raise alarm bells at the coming COP28 climate talks. Other estimates suggest that the threshold will be breached in the 2030s.

Education and awareness

The RSPB is to give under 25s free access to its nature reserves in a bid to increase youth engagement with nature. The charity is set to roll out the two-year pilot program this month. The programme seeks to address what research has shown to be a dip in nature connectedness in teenage years. Similar worries prompted the government to introduce a new GCSE in natural history, and other nature charities are seeking to focus on outreach to the younger generations.

Discoveries

Chimpanzees in Ivory Coast have been observed using military-like tactics to gain an advantage over rivals, a study has revealed. Chimps were observed seeking high ground for reconnaissance missions and making strategic decisions based on the size and proximity of rival groups. This behaviour, similar to the concept of “occupying the high ground” in warfare, may have deep evolutionary roots, according to researchers at the University of Cambridge. 20,000 hours of recordings revealed that chimps would climb hills at the edge of their territories, rest quietly at the top to listen for nearby rivals, and then decide whether to advance or retreat. While many animals take to higher ground to keep watch, chimp tactics are more sophisticated, anticipating where conflict may occur, assessing risk, and making collective decisions on how to proceed.

Diplomacy

An agreement has been reached for a loss and damage fund in the run-up to COP28. The fund, which aims to help countries cope with the irreversible effects of climate change, had been established last year at COP27, but negotiations had come to a standstill over which organisation would administer the fund. However, an agreement was reached in Abu Dhabi over the weekend with recommendations to be considered at COP28 which starts in late November in Dubai.

The Seal Project: Q&A with founder Sarah Greenslade

The Seal Project is an environmental conservation charity based in Brixham, Devon, which monitors, surveys and manages the welfare of seals on and around the South West coast, particularly Torbay and South Hams. Alongside seal conservation, the charity also focuses on engaging, involving and educating the community on the importance of protecting our ocean wildlife through presentations, talks, assemblies in educational settings, workshops and public events. Sarah Greenslade spent many years working as a key member of the British Divers Marine Life Rescue before establishing The Seal Project in January 2019.

Sarah, founder of The Seal Project, took time out of her busy schedule to answer our questions on the amazing work of The Seal Project, the effects of climate change on the local seal population, the importance of raising awareness, and how the current pupping season is going.

What is the Seal Project and where are you based?

The Seal Project is a small conservation charity based in Brixham that monitors the Grey seals in South Devon – mostly around Brixham, but we now also monitor the coast between Dawlish and Prawle Point, including the River Dart. The charity was born out of a need to protect the seals seen locally, many of which are animals we know individually from all around our stretch of coastline.

How did you get into seal conservation?

The story began when I encountered a Common Seal Pup stuck in Brixham’s Shoalstone seawater pool – who do you call at 5.30 in the morning? Myself and my best friend had no idea. The RSPCA don’t wake up that early and we had no clue what to do, but we knew that leaving the pup where it was wasn’t an option as people were walking dogs and the seal was clearly in the wrong place. My partner Lee (now a trustee of The Seal Project) suggested wrapping it up in something and putting it back in the sea. We had no hoodies or coats, so my friends partner was called and he brought down their most luxurious fleecey blanket off their sofa (as you do!) The seal, who had been swimming in the pool, came out and literally stopped at my feet. I scooped up the pup in the blanket as if it was a sleeping child and it never struggled once. We never touched it as we carried it over the rocks to the sea and let it free. As soon as we released it, another seal appeared – knowing what I know now that was most likely its mum – and off they went. The pup had clearly come in on a high tide and got stranded and the mum couldn’t get through the railings. If that was a grey seal it would have been abandoned there and then but Common seals are more devoted mums, and I hope to see this seal as an adult at some point.

After this, I became a Marine Mammal Medic for the British Divers Marine Life Rescue (BDMLR), which sends medics to call outs for marine life in distress, mostly seals, dolphins and whales. My first call out was to a ‘speared’ seal which quite literally resembled a tv ariel in the sea. She was eventually sighted locally without the spear attached, however it seems that every seal has some kind of back wound. She, like all seals, has unique identifying marks including their individual fingerprints and fur patterns, in this case a specific ‘W’ shape to the right-hand side of her head. I knew I had a photo showing that she was alive and well, and that resighting along with later identification of an animal known by the Seal Research Trust (Cornwall Seal Group Research Trust), with whom we share all our data, are what first sparked my interest in using photos to identify individual seals. After providing the identification I spent two weeks getting called out to every seal sighting in search of the previously speared individual, and it’s all gone a bit mad since then!

We are at the end of October, which is around the time Seals finish pupping. What has it been like in the Torbay area for pups this year?

I’ll be honest, it has not at all been as expected. Three of our known mums have not been seen for ages, and a first-time mum has been identified as a seal we know which we didn’t expect to be pupping just yet. The strange summer/autumn weather also means people are now using the coastline with their watercraft year-round and paddleboards and kayaks are now easily affordable too, so people are everywhere. Pupping seals who once had the coastline to themselves once September kicked in are now finding they don’t have these spaces to themselves, and as such pups are born or washed up in busy locations. This often results in a call out to BDMLR (as has just happened on the day I’m writing this).

Being based in a tourist area, what challenges do the seals and The Seal Project face?

That’s a good question. Hand feeding is probably our biggest problem. When we first started, our mentor and amazing friend Sue Sayer MBE thought that us starting a Brixham-based project would have a negative response as this is a major fishing port and some believe that seals ‘eat all the fish.’ But bar the odd comment, and a tiny number of incidents involving fishing and tripper boats hand feeding seals, we have experienced very few problems with the commercial operators in Brixham.

As a tourist area another big problem is angling-line entanglements. Our Breakwater is a busy area for novice anglers and they tend to feed the seals in an attempt to make them go away – clearly that doesn’t work. Also, some seals are sadly too habituated and get caught in angling line regularly. With adult seals there is nothing that we can do about this, and they have to be left to themselves until the hooks rust or fall out. Stones are also often thrown at seals to make them go away, and the animals are uncommon at a couple of locations where more ‘commercial’ land angling takes place.

Our biggest challenge is lack of awareness. We spend so much of our time trying to raise awareness and get the message out there which requires help from the local authorities and the tourist boats, but this doesn’t seem to be happening and it’s frustrating for us. We should all be working together, and the amazing local wildlife – including seals – should be respected and appreciated. Without our incredible wildlife many tourist boats would just be ferry services.

What projects or research have you been carrying out or got planned for the future?

We monitor and record all seals, sightings, dates and locations to try to build up a big picture of the seal population around our coastline. We now know many seals well and have been gathering data since 2016/2017. Matching our seals to individuals from Cornwall is difficult as there are very few other locations on the south cost carrying out monitoring in this way. Therefore, unless an image of a seal happens to be shared on social media or passed onto us from a private group, our records are mostly limited to the confines of our study area.

We do however have sightings of seals which have been released in Cornwall or seen in north Cornwall. We would love to be able to find out where else our seals have been seen and to build a better picture of their travels. Given that we do have Cornish seals visiting our area, we’d like to know if they behave differently to the individuals normally resident in Devon; my Cornish surveys show that the seals there are much more skittish than the individuals we see in Brixham, which tend to be relaxed and show little concern around the noise and traffic of this major fishing port. We do also have a couple of students planning research, but as of yet nothing is confirmed. Our data is not in the best shape and every sighting of each seal takes time to document – identifying one seal can take seconds or hours, and as this is all done by eye the catalogue is a minefield to get involved in!

How has climate change impacted the local seal community?

At this time, I can’t say for sure. My biggest concern is the fact that seal pups, born with white fluffy coats to be camouflaged in snow, are increasingly being born in hot September sunshine, and therefore once abandoned they are at a greater risk of dehydration due to being on sunny warm beaches when it should be much cooler. This year, numbers of seals appear to have been increasing unusually slowly as we head towards the winter months, but we’re yet to reach peak winter season to be able to confirm whether numbers will remain low. Our only other concern at this time is for the three mums who we’ve not yet seen pup this year, as they’ve been so predictable for the past few years.

Do you have a success story you’d like to share with us?

‘Easter Bunny’ is one of my favourite seals and can still be seen today resting around the local area. We first encountered him in 2020 as a juvenile seal entangled in industrial strength plastic. He vanished and we feared the worst, however a week later, on Easter Sunday, he was back in the same haul out spot on a girder in the marina, freed from the plastic. At the time of our first sighting, he appeared to have a bunny shape on his right-hand side (alongside a letter ‘A’), but this time the bunny seems to have disappeared with the ‘A’ is clearly visible. He reappeared regularly over the coming years, often seen for a few days and until the last several months always in the same spot, before disappearing for a few days and coming back again. We have seen him elsewhere a number of times, and last winter he was seen socialising with two ‘tagged’ seals (former rescued seals with plastic rear flipper tags for identification), so we look forward to seeing if they return to the area soon too.

Conservation

Wildcats are thriving in a Scottish Highlands conservation project with only one death. Nineteen of the cats were released into the wild in the Cairngorms National Park in the summer. Thirteen new kittens that have been bred for the scheme will be released into the wild next summer. Wildcats are one of the rarest and most endangered mammals in the UK. They live in moorland and grassland where they feed on small mammals and ground-nesting birds. Interbreeding with the domestic cat has eroded the wildcat’s genetic diversity. They also face threats from feline disease, road collisions and fragmentation of their habitat. A concerted effort by the Saving Wildcats project which brings together the expertise and skills of a range of national and international organisations provides a glimmer of hope for the species in Scotland.

David Attenborough’s Planet Earth III is both horrifying and awe-inspiring, critics have said. The opening episode of the third instalment of the highly acclaimed nature documentary series was viewed by 5.6 million people and has been described as “visually stunning” and “majestic”. The latest series of Planet Earth has a notably darker mood than its predecessors, focusing on animals fighting for survival in the face of constant environmental change.

Discoveries

The mysterious death of 385 elephants in Botswana and Zimbabwe in 2020 was caused by a little-known bacterium, scientists have revealed. Elephants were found walking in circles before suddenly dying by collapsing on their faces in Botswana’s Okavango Delta and north-western Zimbabwe. Tests on the elephants have now shown that the cause was a bacterium called Pasteurella. The bacterium can result in septicaemia under certain conditions and has been linked to the sudden death of around 200,000 saiga antelopes in Kazakhstan.

Climate crisis

Increased melting of the West Antarctic Ice Sheet is unavoidable, according to new research. Scientists ran simulations and found that even under best-case emission scenarios, melting would increase three times faster than during the 20^th century. The West Antarctic Ice Sheet holds enough ice to increase global sea levels by up to five meters. Significant sea level rises will be catastrophic for the millions of people living in coastal and low-lying areas.

The Greenland Ice Sheet could experience runaway melting if climate targets are not met. A study in Nature has suggested that the ice sheet’s melting will accelerate significantly if average global temperatures surpass a threshold of 2.3 C above pre-industrial levels. However, the scientists stress that action in the future could reduce ice loss even if the threshold is crossed. They argue that it is cheaper and easier to take action now rather than clawing back towards lower global temperatures later.

Atlantic hurricanes are more quickly strengthening from weak storms due to climate change. Scientists have said that human-caused climate change is creating the conditions that lead to a quick intensification of storms. Hurricanes are fueled by high ocean surface temperatures which have been increasing in recent years as the world’s oceans have absorbed over 90 percent of the excess warming from fossil fuel emissions. This presents a challenge for coastal communities as forecasting becomes more difficult the quicker a storm intensifies.

Policy

Countries are deadlocked over a “loss and damage” fund before COP28. The fund was agreed last year at COP27 in Egypt and is designed to help countries recover and rebuild from damage due to climate change. Developing and developed countries are at odds about which organisation should oversee the fund, which countries should pay and who will be eligible to receive funding. Developed countries back the World Bank as the host of the fund; however, developing countries argue that this would give donor countries too much influence over the fund. Talks stalled recently in Aswan, Egypt and the committee responsible for designing the fund will meet again on November 3^rd and 4^th before the COP28 summit begins later in the month.

£1 billion electric vehicle fund remains unallocated three years after it was first announced. The fund was first announced in March 2020 prior to the first Covid lockdown. The fund was intended to be used to support electrical capacity at service stations to allow for rapid charging of electric vehicles. While 96% of motorway services already have charging stations, increased use of electric vehicles means that there will be a demand for more charging capacity.

This week in biodiversity news – 16th October 2023

Extreme heat from climate change may make parts of the Earth uninhabitable. An interdisciplinary team of researchers from the Penn State College of Health and Human Development, Purdue Institute for a Sustainable Future and Purdue University College of Sciences modelled global temperature increases from 1.5°C to 4°C – a worst-case scenario. They found that a further increase of around 1°C would mean that 2.2 billion people would experience many hours of heat that surpass human tolerance thresholds. It would be particularly concerning for residents of high-humidity areas where heatwaves would be considerably more dangerous for human health.

Whales and dolphins in the US are losing food and habitat to climate change, according to a new study. Researchers from the National Oceanic and Atmospheric Administration found that over 70% of American marine mammal species stocks are vulnerable to threats associated with warming waters. This includes shrinking food and habitat availability, changes to ocean chemistry and reduced dissolved oxygen levels. Large whales such as North Atlantic Right Whales and Humpbacks are most at risk from the effects of climate change. This comes on top of new research published in Nature Climate Change that suggests that marine heatwaves are infiltrating deeper parts of the ocean, the consequences of which could have widespread impacts on marine ecosystems.

Beavers have been reintroduced to west London for the first time in 400 years. The release of a family of five Eurasian Beavers to wetlands in Ealing comes as part of a push to improve biodiversity and mitigate the impact of climate change. There had been plans to spend money on flood prevention measures in the area but beavers were considered to be a more cost-effective natural solution.

Canada rejects pleas from environmental groups to protect endangered owl habitat. One wild-born owl remains in British Columbia where logging has severely impacted the species’ old-growth forest habitat. The decision means that the future of the species is uncertain. The rejection of an emergency order for the protection of the owl comes after an eight-month delay since the environment ministry was required by law to recommend an emergency order under the Species at Risk Act. Environmental groups have responded with legal action following the delay. Biologists advise that the species could recover with adequate protection of old-growth forest habitat.

Extinction Risk

Almost half of flowering plants could be threatened by extinction, scientists have warned. Researchers analysed data from the World Checklist of Vascular Plants, the world’s most comprehensive database of plants available, and the International Union for Conservation of Nature’s Red List of Threatened Species and found that 45% may be at risk of extinction. Other key findings suggest that 77% of the 19,000 new plants and fungi species discovered since 2020 are endangered and that only 10% of an astounding 2.5 million species of fungi have been discovered.

Similar numbers of male and female sea turtles give hope for the survival of the species. Papua New Guinea’s Conflict Group’s analysis of turtle hatchings between 1960 and 2019 showed that an average of 46.2% have been female. Sea turtles are susceptible to rising temperatures due to their sex determination being temperature dependent. Scientists suggest the results are “likely rare in the global context” with sand temperatures having risen by 0.6°C over the same period. Another study of Green Sea Turtles from the same latitude showed that more than 99% of hatchlings were female, spelling decimation for the population.

Discoveries

A small West African crocodile can moo like a cow, audio recordings reveal. Scientists use audio recordings to monitor elusive crocodile species which are difficult to confirm via visual surveys. The tiny African Dwarf Crocodile (Osteolaemus tetraspis) inhabits the swampy forests of West Africa. Scientists believe that the crocodile is quite common given its common occurrence in the bushmeat trade. Consequently, they are using audio recordings to listen out for its calls and have discovered that the crocodile, surprisingly, moos like a cow.

Animals fear the sound of a human voice more than that of a lion, according to researchers. A study in South Africa’s Kruger National Park found that, when playing recordings of human voices, 95% of animals were extremely frightened and ran away. Snarling and growling lion recordings provoked significantly less alarm among the wild mammals. The response to the recordings, which included human speech from local languages, suggests that animals have learnt that contact with humans is lethal. Researchers have noted that this may present a challenge for areas relying on wildlife tourism, as visitors can inadvertently scare away animals.
