Climate Crisis

A new study reveals the Amazon rainforest’s worst drought on record in over half a century, with human-caused climate change acting as the driving force behind these weather extremes. The Amazon rainforest plays an important role in the removal of CO₂ from the atmosphere, and accounts for around 10% of the world’s species. However, scientists suggest the Amazon could soon reach a “tipping point”, with droughts such as these expected every 13 years if global temperatures increase by a further 2°C.

Black Rhinos have returned to Kenya’s Loisaba Conservancy as species recovers following local extinction 50 years ago. This translocation project, the result of a collaboration between Loisaba Conservancy and Kenya Wildlife Service, was prompted by the news that Kenya’s 16 Black Rhino sanctuaries are rapidly running out of space due to a boost in population numbers. Twenty-one of these critically endangered Black Rhinos were released into a specially created fenced sanctuary that covers nearly half of Loisaba’s total area, marking an important moment in the long-term future of Black Rhino populations in Kenya.

Hedgehog populations are on the rise according to BBC Gardeners’ World survey. Previous reports have found that since 2000, the number of hedgehogs has fallen by 30%-75% depending on the area due to increased habitat loss, fragmentation, pesticides, and a reduction in food sources. However, the annual hedgehog survey highlighted a 33% increase in sightings, up from 31% in 2022, which has been aided by the instillation of ‘hedgehog highways,’ and nationwide rewilding efforts. CEO of the British Hedgehog Preservation Society, Fay Vass, stated that urban populations are still lower than they should be, however these results provide cautious optimism for the future of hedgehogs.

Environment

Hailed as one of the world’s most ambitious environmental policies, Biodiversity Net Gain came into effect in England on the 12th February 2024. It is now mandatory for all new developments in England to deliver at least a 10% net gain in biodiversity or habitat on all new sites. In light of the government target of building 300,000 new homes a year by the mid-2020s, it is hoped that the scheme will minimise or mitigate the environmental effects of these new developments.

Iceland may be entering a new volcanic era, with increasing volcanic activity reported across the island. The most recent short-lived eruption on the Reykjanes peninsular marks the third since December 2023, and the sixth since 2021. Researchers think this wave of volcanic activity may be following a pattern that could last for decades, or even centuries. Scientists are trying to work out how to predict future eruptions by tracking ground inflations as magma rises, from which they can estimate when the magma will break the surface.

Science and discoveries

The latest strain of bird flu has decreased Great Skua populations by 75% and Northern Gannet populations by 25% in the past 2 years alone, says the RSPB and British Trust for Ornithology (BTO). According to a recent report, the H5N1 strain has been noted as one of the biggest conservation threats facing numerous seabird species across both UK and Europe. The latest Seabird Count survey, published in November 2023 – which did not take into account the effects of bird flu – found that almost 62% of seabird populations were already in decline across the UK due to other factors such as fishing and offshore wind developments.

The most vulnerable migratory species are at risk due to increased human activity, with one in five threatened with extinction according to the UN. Despite the signing of the Convention on the Conservation of Migratory Species of Wild Animals over 40 years ago, researchers suggest that more focus has been placed on preventing illegal animal trading rather than upholding the law on illegal killing. The report recommends that countries need to establish key biodiversity areas on the migration pathways of endangered species, reduce infrastructure obstructing migration routes, create corridors of protected land, and restore 30% of degraded marine and land areas.

Climate crisis

The UK has approved 24 new North Sea oil and gas licenses in the face of significant criticism. The move angered many environmental campaigners and MPs who labelled the decision as “grossly irresponsible”. The government defended the move stating that the oil would be imported from overseas if it wasn’t extracted from the North Sea. Environmentalists have argued that granting the licenses will do relatively little to improve the UK’s energy security and undermines Britain’s move towards net zero emissions.

Conservation

The National Trust has committed to recreating lost rainforests by planting 100,000 trees in North Devon. Temperate rainforests once covered vast swathes of western Britain, but the rare habitat declined due to historic deforestation and continues to face threats from air pollution, invasive species and diseases. It is now one of the most endangered habitats in the UK covering only 1% of Britain’s landmass mostly in Cumbria, Devon, Cornwall, North and West Wales and the West of Scotland. Exceptionally heavy rainfall and high humidity levels allow moisture-loving plants like mosses and lichens to thrive in these areas and the restored rainforest will be a haven for rare specialist plants that depend on this habitat.

Environment

Toxic run-off from roads has been found not to be monitored, according to the BBC. Rivers close to major roads have been tested by campaigners and have been found to contain a cocktail of chemicals and particles from the roads. National Highways has a statutory responsibility to make sure that discharges from its network do not cause pollution and the Environment Agency is responsible for monitoring water pollution in England. However, in response to a freedom of information request, the agency said that it did not regularly monitory run-off. Oil, chemicals and wear from tyres are washed down drains in heavy rain and subsequently flow into rivers and streams causing damage to sensitive aquatic ecosystems.

The government remains largely off track to meet its environmental targets, according to the Office for Environmental Protection (OEP). The OEP’s annual progress report concludes that while some progress has been made, the government is largely off track to meet both targets and legal obligations and that the government must speed up its efforts and implement policies quickly to bridge the gap.

Extinction risk

The Greater Glider is on course for extinction due to a controversial decision by the Australia’s New South Wales environmental watchdog, according to experts. The Environment Protection Authority (EPA) told stakeholders that it was scrapping measures that required a government-owned forestry corporation to search for Glider dens which currently have to be given a 50-metre logging exclusion zone. Experts have told the EPA in no uncertain terms that they are effectively locking in the Glider’s extinction. Greater Gliders rely on between six and 20 den trees for its habitat which is already under significant pressure due to summer bushfires and logging activity.

Science and discoveries

A new map has revealed that England’s hedges would wrap around the Earth ten times if lined up end to end. The map is the most comprehensive to date revealing a total of 390,000 km of hedgerows. Researchers from the Centre for Ecology and Hydrology used Lidar (Light Detection and Ranging) remote sensing data. They found that the South West of England boasted the largest share of hedges accounting for 24% of England’s total with Cornwall leading at the county level. Around half of Britain’s hedges were lost in the post-war period, and while losses have slowed since the 1990s, major threats to Britain’s hedgerows remain.

The birth of a Great White Shark may have been captured on video for the first time. Wildlife filmmaker Carlos Gauna and UC Riverside biology doctoral student Phillip Sternes were filming California’s coastal waters with their drone when they spotted something unusual. By enlarging the images from their video footage and putting it in slow motion, they realised a white layer was being shed from the body of a shark. They believe it was a newborn white shark shedding its embryonic layer.

The Big Garden Birdwatch: NHBS Staff Results 2024

The RSPB’s 45th Big Garden Birdwatch took place between Friday 26th and Sunday 28th January 2024. This annual event is one of the largest citizen science wildlife surveys in the UK and helps us gain an understanding of how our garden bird populations are changing in abundance and distribution over time. Over half a million people took part in last year’s event, recording a total of 9.1 million birds. House Sparrows took first place, despite a gradual 57% decrease in sightings since the first Birdwatch Count in 1979. They were closely followed by the Blue Tit and Starling.

Although the Big Garden Birdwatch has finished, there is still time to submit your results on the RSPB website by the 18th February, or by post before the 13th February. Even if you didn’t see anything, it still counts!

With birds being faced with an increasing number of challenges each year, it’s more important than ever to make your garden and outdoor space wildlife friendly. This can include installing bird feeders or tables which provide an important food source throughout the winter months when natural food sources are scarce., You can also provide clean, fresh drinking water in shallow containers such as bird baths or saucers, and install nest boxes for breeding in the spring. Also, don’t forget to regularly clean and maintain your feeders and baths as this helps stop the spread of disease. Head over to the RSPB website to find out more about how you can help your garden birds.

Author Q&A with Derek Gow: Hunt for the Shadow Wolf

Renowned rewilder Derek Gow has a dream: that one day we will see the return of the wolf to Britain. As Derek worked to reintroduce the beaver, he began to hear stories of the wolf. With increasing curiosity, Derek started to piece together fragments of information, stories and artefacts to reveal a shadowy creature that first walked proud through these lands and then was hunted to extinction as coexistence turned to fear, hatred and domination.

With bitingly funny but also tender stories, Hunt for the Shadow Wolf is Derek’s quest to uncover the true nature of this creature because, as we seek to heal our landscape, we must reconcile our relationship with it. Before we can even begin to bring the wolf back, we need to understand it.

Derek recently took time out of his busy schedule to talk to us about Hunt for the Shadow Wolf, including how his fascination with the wolf began, what role it could play in Britain’s landscape and more.

As well as being packed with personal stories and fascinating snippets of wolf biology and behaviour, Hunt for the Shadow Wolf is an incredibly well-researched history of the wolf, told through the myths and legends that abound throughout our lands. How and when did your fascination with the wolf and its history in Britain begin?

My personal interest in the wolf story began early. I remember quite clearly my grandmother, who was a slight, erect, sprightly soul, telling both myself and my bored brother on a long car journey to Dundee the story about a place called wolf clyde which was near to where we lived in the Scottish borders at that time where the last wolf in Scotland was killed. It was just nonsense about a woman with children being attacked by the wolf which she brained in response with a pancake griddle, but nevertheless it began a slow smoking interest in the old myths which given the opportunity I was keen to explore further.

Why do you think that an understanding of the historical culture, myths and legends surrounding a species has relevance to its conservation and role in our ecosystems today?

A factual understanding of the history of this much maligned species in Britain is very important as the lies we made up in the darkness of our ignorance to try to twist the cultural character of the wolf into one of loathing and repulsion still sway the responses of a phenomenal number of individuals and organisations to this day. Despite the very best of our advanced understandings of what wolves are and what they do, this toxic taint is still bubbling strongly.

Even in children’s tales, the wolf invariably represents a character of fear, violence and threat. Do you think these types of stories have a significant role to play in the development of our feelings towards wolves as adults?

Absolutely as they reflect only the darkness in the minds of the adults who wrote them and by so doing chose to corrupt a bad reputation without thinking into an even darker evil to infect the minds of the young. Nowadays it’s gratifying to see in so many good environmental centres throughout Europe, within the wolves expanding range, more understanding and compassionate explanations about both their history and the reality of living with them.

Britain is in a unique position compared to mainland Europe in that wolves will never be able to repopulate of their own accord. Do you think that a reintroduction project will ever occur, and what are the key challenges that stand in its way?

I think we should reintroduce the wolf and prepare the way for even more of our lost beasts. Farming has had it all its own way without balance of any sort. If a species gets in our way, we kill it. It’s what we are doing to badgers right now. In the past we inflicted so much heartbreakingly visible cruelty. Now, we destroy on a scale that’s colossal without thinking about the smallest of creatures and those tinier still that inhabit the soil. It’s a viciously unnecessary process.

What role do you think the wolf could have in healing the landscapes of our currently denuded Britain?

I think they would both move deer considerably and by doing so disrupt their grazing patterns for the betterment of forest understory regeneration. I think they would make those that keep sheep consider their worth and then, if these animals are of value, protect them better. I think their very presence, wild but unthreatening, would more than that of any other creature enable all of us now living on this island to establish, if we wished to do so, our relationship with the natural world.

As well as travelling widely to locations where wolves live in the wild, you have also had the incredible experience of hand-rearing wolves in a wildlife centre. What is your most memorable first-hand experience with a wolf or wolf pack?

Naida, one of my tame cubs, ate my car keys. I only had one set and had to wait for what seemed an eternity for them to pass through her before picking my way through her enormous turds to get them back.

Finally, what is occupying your time this winter? Do you have plans for more books?

Lots of things. The last of bits of farming – feeding my cows. Dog walks and avoiding the rain. Trying to develop a foundation to help us breed even more threatened British species for reintroductions. And books? Well, on long dark evenings I have been researching the intriguing history of the European Bison. not the bits of sadness that brought the species to its knees in the early 20th century, but the complicated individuals who for a time held its future in the palms of their hands. Great characters like the 11th Duke of Bedford, who assembled breeding herds of threatened species on his Woburn estate, and tyrants like Hermann Goering, who used slave labour to create vast parks within which he hunted. It’s an intriguing slant that’s little known but it saved the species for a time when the world for them has become a better place where they can roam in peace, a range that is vast. There might be a book in that!!

This week in biodiversity news – 15th January 2024

Extinction

A recent study has found that humans have wiped out double the number of bird species as previously thought. According to the Centre for Ecology and Hydrology (UKCEH), 1,400 bird species have been made extinct which amounts to 12 percent of species being lost due to modern humans. The causes of the destruction of so many species include habitat loss, overexploitation and the introduction of species which have competed with native species and hunted them as prey. The loss of so many bird species is likely to have had harmful effects on ecosystems due to their key functions such as seed dispersal and pollination and because of the range of other species that depended on them for survival.

The mystery of the extinction of the largest ever primate has finally been solved. Until recently, the extinction of Gigantopithecus blacki, a giant three-meter tall 250-kilogram primate that lived in the plains of southern China, was a mystery. A large study by a team of researchers from China, the US and Australia of 22 caves in China found that the species on the brink of extinction between 295,000 and 215,000 years ago struggled to adapt to its changing environment. While other primates such as the orangutan adapted their eating habits and behaviours in response to this change, Gigantopithecus blacki struggled to adapt, and as a consequence went extinct.

Biodiversity at risk

The Nigerian Government has destroyed £7 million worth of elephant ivory. The stock of elephant tusks was one of the largest ever seized in Nigeria and weighed close to 2.5 tonnes. Tens of thousands of elephants are killed worldwide each year for their tusks which are often carved into highly valuable works of art. It is estimated that fewer than 500,000 elephants persist in Africa, a considerable decline from 1.3 million in the 1970s. The destroyed ivory will be pulverised into powder which will be made into a monument symbolising the importance of elephant conservation in Nigeria.

Norway is set to approve deep-sea mining operations despite major environmental concerns. The move will make Norway the first country in the world to open up its seabed for deep-sea mining. Scientists have voiced considerable concern over the potential impact on marine life and carbon storage. Recent studies in Norwegian waters have shown that mining operations would have severe impacts on unique marine wildlife. The EU and the UK have opposed such a move citing environmental concerns. Norway has claimed that exploiting deep-sea mineral deposits will aid the green transition.

Climate crisis

Scientists have confirmed that 2023 was the hottest year on record. Last year saw temperatures 1.48°C warmer than the long-term pre-industrial average temperature. The record high has been driven by a combination of human-caused climate change and the natural El Niño weather phenomenon. The latter half of 2023 saw temperature records for the time of year being broken almost every day with a worrying increase above previous records. 2023 was also notable for extreme glacial retreat, Antarctic sea-ice lows and record ocean temperature highs which far exceeded previous records.

Germany’s greenhouse gas emissions hit a 70-year low in 2023, according to a German think tank. The low comes as Germany winds down its coal-fired power production resulting in a reduction of 73 tonnes of greenhouse gas emissions this year. This was made possible by reduced overall electricity demands and increased foreign imports from renewable energy sources. However, the study also highlighted that only 15% of the total can be counted as permanent emission reductions with a large proportion due to unpredictable social or economic activity.

Farmers have called for stronger river defences after Storm Henk wreaked havoc on their crop fields. Many thousands of acres of agricultural land have been left sitting under water in the wake of the storm which follows Storm Babet and Ciaran in the autumn. The National Farmers Union has also called for compensation for farmers who are directed to let their fields flood as part of efforts to protect towns from flooding. The extreme flooding has caused significant financial stress for many affected farmers. The government has said that £221 million was being spent on flood defence maintenance in 2023/2024.

Scientific discoveries

Sperm Whales live in culturally distinct units, a new study has revealed. Scientists at Dalhousie University, Canada, analysed Sperm Whale feeding habits and the sounds they made using underwater microphones and drone surveys and found that they organised themselves into female-based groups of up to 20,000 animals. These groups were divided by distinctive sequences of clicks in their vocalisations. The researchers discovered that while different clans of the whales might meet, they never interbreed, recognising and maintaining their differences.

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.

Conservation

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.

This week in biodiversity news – 11th December 2023

Conservation

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.).
