Dutch scientists have revealed that corvids are using anti-bird spikes to build their nests. Anti-bird spikes are often attached to building ledges to prevent birds from nesting, and this discovery was prompted when nests constructed almost entirely from the sharp metal objects were found in Rotterdam and Antwerp. It has been suggested that the spikes may help protect their nests and could even be used as a display to impress potential mates.
Salinity changes are threatening marine ecosystems, according to researchers at the University of North Florida. Changes in salt content can occur due to land use and climate change and are expected to intensify with warming oceans. Vital estuarine and coastal zones could quickly face ecosystem collapse as groups such as corals, plankton and seagrass are affected by the changes.
Climate crisis
Global average temperatures reached a new high for the third time in a week at the start of July. A record of 17.01°C early in the week was broken twice more with average temperatures reaching 17.23°C on the Thursday. While unofficial, the record points a concerning trend in recent decades of higher year-on-year global temperatures. Scientists have attributed the cause of the unprecedented temperatures to a combination of human-induced global warming and the El Niño climate pattern.
The global shipping industry has agreed to a goal of net-zero by 2050. Industry voices and small island nations have largely welcomed the deal, but it has provoked fury among environmental groups who believe the plan will do little to keep temperatures below the 1.5°C threshold set out as part of the Paris climate agreement in 2015. Shipping is responsible for around 3% of CO2 emissions and campaigners are warning that emissions targets set out in plan will see the shipping industry exhaust its carbon budget by 2032.
One of the UK’s rarest and most threatened birds continues to thrive at Newport Wetlands National Nature Reserve in Wales. This year’s nest sites have seen the fledging of six Bittern chicks due to the provision of high-quality reedbed habitat. Bitterns were previously driven to the point of extinction following persecution and habitat loss. The reserve’s wetlands are managed by Natural Resource Wales in partnership with Newport City Council and the RSPB. Wetlands are also valuable in the battle against climate change acting as important carbon stores.

A phasing down of fossil fuels is inevitable and essential, Cop28’s president has said. Sultan Al Jaber has called for a ramping up of renewable energy capacity to enable fossil fuel use reductions. He will host the climate talks which will be held in the United Arab Emirates in November where a Cop28 plan for a target of tripling of global renewable energy production is expected to be announced.
A new study indicates that megalodon, the extinct shark species, were warm-blooded. The researchers found that Otodus megalodon may have had a body temperature that was significantly higher than other sharks, more consistent with having a degree of internal heat production similar to that of modern warm blooded animals. The higher metabolic costs associated with this may have contributed to its vulnerability to extinction.
Joshua trees are officially protected in California, after the passing of the Western Joshua Tree Conservation Act. This law bans the removal of Joshua trees without a permit, creates a fund to protect the species and mandates consultation on the rule’s implementation with Native American tribes. According to scientists, by 2100 just 0.02% of the tree’s habitat in Joshua Tree National Park will remain viable without mitigating climate change.
A new study has found that bats thrive in restored wetlands. Researchers from the University of Turku measured the impact of wetland restoration on bats. The Hydrology LIFE project has successfully restored more than 5,000 hectares of wetlands across more than 100 locations. The study, which is part of this project, showed that wetland restoration can significantly increase the activity of bats. By monitoring bat activity in 21 sites across Finland over four summers between 2018-2022, the researchers were able to attribute this notable increase in activity to the improved abundance of insects in these areas.
Natural England has designated a Cornish moorland as a nature conservation area. The 59 blocks of land in Penwrith Moors in Cornwall are now sites of specific scientific interest, a move aiming to preserve precious flora and fauna. There has been criticism from farmers, as this would mean further restrictions. Natural England decided this area, which covers around 3,000 hectares, should be designated an SSSI because it is an important habitat for rare birds, plants and insects.
A new funding partnership between Beaver Trust and the Ecological Restoration Fund will help to support the restoration of and co-existence with beavers across Britain. This £150,000 grant will be used to support two key areas of Beaver Trust’s work: releasing beavers into new sites and providing their team with the equipment and resources they need to carry out mitigation and trapping.
Extinction risk
Reef sharks are facing a heightened extinction risk. A new study has revealed that overfishing is pushing reef sharks towards extinction, with a global decline of 63% on average in five of the main shark species living on coral reefs. After studying 22,000 hours of footage from stations across 391 reefs in 67 nations and territories, the researchers found that grey reef, blacktip reef, white tip reef, nurse and Caribbean reef sharks are all in decline.
Rainforest loss accelerated last year compared to 2021, despite the pledge signed by 100 international leaders to end deforestation by 2030. Brazil led in rainforest loss, with a 15% increase over the prior year. The Democratic Republic of the Congo, the country with the second-most rainforest, also had major losses last year, much of which was agriculture related.
Brazilian authorities have announced the seizure of almost 29 tons of shark fins, coming from an estimated 10,000 blue and shortfin mako sharks. It is believed that the vessels used fishing gear specifically for targeted shark fishing, which is prohibited. Shortfin mako sharks were placed on the country’s endangered species list in May and blue sharks are under consideration for inclusion.
New discoveries
The Victorian grassland earless dragon has been rediscovered, having been thought to have been extinct in the wild since 1969. This species was once widespread in the native grasslands west of Melbourne but the population declined due to habitat loss and predation. Zoos Victoria had been actively searching for the dragon since 2017 and, now a surviving population has been found, are working to establish a plan to ensure the species’ survival.
Fears of hottest year on record as global temperatures spike. Preliminary global average temperatures taken so far in June are nearly 1?C above previously recorded June levels since 1979. It is thought that the gathering El Niño event may propel 2023 into becoming the hottest year ever recorded. This naturally recurring phenomenon will likely add heat to the long-term warming conditions already caused by the burning of fossil fuels.
Devon’s Wildlife Trust (DWT) is planting a temperate rainforest near Totnes with its share of a £38 million Aviva fund. The 30-hectare site has a 105-year lease, which will allow DWT to plant two-thirds of the land with native tree species. Rainforests of the British Isles have been largely destroyed over hundreds of years, now covering less than 1% of Britain. DWT will create new rainforest close to existing examples of the ancient, wooded landscapes in the Dart Valley and on the southern edges of Dartmoor.
Rare hazel dormice will be reintroduced into the National Forest near Calke Abbey in Derbyshire. This native species has seen a 51% decline nationally since 2000 and is locally extinct in the area. People’s Trust for Endangered Species (PTES), which will release 38 individuals, is working as part of Natural England’s Species Recovery Programme. Since 1993, 1,078 dormice have been reintroduced to 25 different woodlands in 13 countries.
Around 20 captive-bred wildcats are being released in secret locations across the Scottish Highlands. The animals were raised in captivity as part of a breeding programme run by the Royal Zoological Society of Scotland, which aims to release up to 60 individuals over the next three years. Scottish wildcats are functionally extinct in the wild in the UK, therefore it is hoped that these reintroductions will help to save the species.
Extinction risk
Campaigners fear that East West Rail will lead to the loss of rare species. A new route between Bedford and Cambridge has been confirmed, with the spokesman for the line saying that chosen route would offer an “environmentally sustainable solution”. However, local campaigners believe the scheme could threaten Red List species, such as skylarks and yellowhammers. They believe an ancient woodland which provides habitats and a local wildlife corridor will be dramatically impacted by the route. The company has committed to a 10% net biodiversity gain target across the whole project, however, and has already established 20 ecological compensation sites across the first stage.
A new study is warning that the mass “sixth extinction” is well underway, with nearly half of the world’s animal species now in danger of becoming extinct. The study, More Losers than Winners, examined global population trends from approximately 71,000 animal species. They aimed to determine how many are at risk due to threats such as loss of habitat, harmful use of pesticides and herbicides, and the long-term impact of the climate crisis. The researchers found that only 3% of animal species were growing, while 49% showed stagnant population growth. 48% showed declining populations.
New discoveries
A new flying gecko species has been discovered in northern India. The Mizoram parachute gecko is one of 14 geckos known to take to the air, using a combination of skin flaps and webbed feet. The researchers hope that this new discovery will highlight the underappreciated biodiversity of northern India and encourage greater efforts to document its wildlife.
The first national Marine and Coastal Wildlife Code has been launched in England, which will protect animals and habitats by helping people enjoy the coast responsibly. England’s coastline contains vitally important habitats, including sand dunes, saltmarshes and a significant proportion of Europe’s vegetated shingle beaches. The coastline also supports a number of key species, such as 95% of Europe’s grey seal population and 25% of Europe’s breeding seabirds.
This builds on the existing Countryside Code but only applies to England. Scotland, Ireland and Wales have previously produced similar coastal and marine wildlife codes and guidance, which should be reviewed if you are looking to visit these areas.

What does the code include?
Similarly to the Countryside Code, this new code aims to act as a guide to help visitors act responsibly around marine wildlife. We all have a responsibility to protect our local wildlife. The guidance from the UK government for England is:
1. Be aware of how you could cause a disturbance
Many people may not realise the impact disturbing wildlife can have, but if an animal is repeatedly disturbed, it can lead to stress, injury and even death. You can also displace animals from their preferred habitat, disrupting behaviours such as migration, breeding, feeding and resting. This disturbance can also increase their vulnerability to predators.
The impact of disturbance on seals has been brought to the public’s attention in recent years, with many organisations calling for people to be aware of the damage caused. Disturbances that force seals to flee from haul-out sites into the sea can result in them struggling to put on or maintain weight and unable to properly feed their pups. Seals can also receive injuries such as gashes from sharp rocks or even broken ribs, which can be difficult for a diving species to heal from. Increased vigilance also wastes energy and can reduce the amount of time spent feeding or resting. This increased energy expenditure can increase stress as well as the seal’s vulnerability to disease, reducing overall fitness and increasing mortality rates.
You can disturb wildlife by approaching or touching an animal; crowding, circling, separating or chasing them; feeding them; making noise; or damaging or altering habitats. This can include disturbance by dogs, therefore pets should be kept on a lead or under effective control when at the coast. An easy way to reduce your impact is to remember that if an animal has repeatedly noticed you, you have caused a disturbance and it is best to move away and take a wider berth.

2. Know when wildlife are most vulnerable
There are certain times when animals are particularly vulnerable, such as during breeding seasons, in winter and when they’re resting or moulting. It can be difficult to know when these times are, as they often differ between different species. Therefore, it is important to check signs in local areas, as they should tell you where there are access restrictions, and to research the wildlife in the area you are heading. Local councils, Wildlife Trusts and local harbours or ports may be able to provide you with this information.
For seabirds, ‘bird nesting season’ is officially from February until September, therefore it is important to consider access restrictions, dog activities and the impact you may be having on an area during this time. Certain species, such as ringed plovers and oystercatchers, lay their eggs on open ground such as beaches, with little to no surounding vegetation, and so these eggs are vulnerable to being stepped on. Local councils may put up signs in areas where these species are known to breed to discourage visitors but caution should be taken on any beach.
Breeding and pupping season for grey seals can start as early as June in the UK, lasting until January. Pups are particularly vulnerable to human disturbances as this can cause a seperation between the mother and pup or interrupt lactation, potentially leading to pup abandonment. Due to their heavy white coat, grey seal pups can’t swim during their first few weeks and will be left on beaches while their mothers hunt. If disturbed, they are therefore unable to swim away. Addtionally, disturbances that cause stampeeds during pupping season can increase pup mortality rates. You should never approach a seal pup and if you suspect one has been abandoned or is in need of attention, you should keep your distance and call for help.
Other important breeding periods are March to September for seahorses and summer months for cetaceans. Additionally, the September to March wintering season is important for many birds, as they use this time to conserve energy and build up reserves, often for long migrations. Disturbance during this time can reduce their likelihood of survive winter or these migrations.
3. Recognise when you are causing a disturbance
Many people do not have negative intentions and simply wish to appreciate and experience the wonderful wildlife we have along out coastlines. But it is important to recognise the signs for when animals are becoming uncomfortable with your presence.
There are a number of behaviours you can look out for that will indicate a disturbance. For birds, this includes moving away from you, in flight or by walking; flapping their wings at you; and attacking. Seals are more likely to look directly at you, move suddenly from a restful position, suddenly dive into the water, or swim away from you. Cetaceans such as dolphins and whales will slap the water with their flippers or tail, dive away from you, or group together. Other species such as sharks, skates, rays, turtles or seahorses will swim away if disturbed and should not be followed.

4. Act responsibly
This is the main aim of this code, to encourage people to use common sense and act responsibly. As a rule of thumb, try to stay at least 100 metres away from any wildlife and try not to approach animals from behind or head-on. If you notice any signs of disturbance, you should immediately and calmly move further away.
You should never chase, follow or harass any wildlife. It is important to not feed or touch wildlife either, as you could unintentially be causing serious harm. Other actions such as creating loud noises and using flash photography should be avoided.
5. Use watercraft responsibly
Crafts like boats and jetskis can be a disturbance to wildlife as they can injure animals and create noise both above and below the water. You should slow down to under 6 knots if you notice an animal, stay at least 100 metres away (further if you notice that you are causing a disturbance), and keep even more distance if there are more than two watercrafts nearby. You should also maintain your engine to reduce noise and make sure to launch or moor your craft correctly.

6. Enjoy water activities without harming wildlife
It is important to take care not to disturb wildlife when you enter or exit the sea, therefore you should avoid doing this through sensitive habitats, including saltmarshes, mudflats, maerl beds, seagrass meadows and areas where marine wildlife are resting, breeding, nesting or feeding.
7. Report wildlife crime
If you see someone intentionally or recklessly harassing, injuring, disturbing, taking or killing an animal or damaging their habitat, you should report it. Call 101 to report an incident that has already happened, or 999 for a crime in action. Certain actions can incur fines of up to £5,000.
Our coastline and marine life are under serious pressures from a variety of threats, including climate change, disease, habitat loss, reduced food availability (usually due to overfishing), pollution and human activity, all of which already negatively impact marine wildlife. Repeated disturbances can combine with these other pressures, causing reduced fitness and increasing mortality rates.

Is this effective guidance?
This code was developed in collaboration with a number of wildlife organisations, including the RSPB, Shark Trust, Whale and Dolphin Conservation and the Cornwall Seal Group Research Trust. It is not a law or regulation but does help to raise awareness of the impacts you can have on coastal and marine wildlife, while also offering practical guidance to minimise or even eliminate these impacts. While this is unlikely to prevent those with negative intentions, it does provide a great basis to help educate the vast majority of the public on how to be responsibe around wildlife. With reported disturbance incidents more than tripling in Cornwall alone since 2014, and with the ongoing work to establish the King Charles III England Coast Path (a 2,700 mile waymarked coastal path), this new code is a welcome step towards reducing and preventing incidents.
A whale shark was observed feeding at the seabed for the first time. This species usually filter-feeds on plankton at the sea surface; this unusual behaviour was filmed by an ecotourism guide. A new study, published in May 2023, proposes that whale sharks actively feed on benthic prey, either in deep water environments or where the abundance of this prey exceeds that of planktonic food sources.

Irish geneticists have discovered how some species may have been able to survive a mass extinction. Scientists at Trinity College Dublin unearthed a ‘dramatic evolutionary event’ in sturgeon and paddlefish populations. The species’ entire genetic makeup was ‘copied and pasted’ so that it had twice the genetic material it had before, providing more opportunities for mutations and evolution to occur. By strengthening their genetic mix, they might have been able to facilitate their re-establishment after a major mass extinction 200 million years ago.
Pollution
The River Wye has had its health status downgraded after a wildlife review by Natural England. The status changed from “unfavourable-improving” to “unfavourable-declining”, meaning that the river’s condition is worsening. The assessment showed that the river has experienced declines in certain key species, including Atlantic salmon and white-clawed crayfish. Previous studies linked this decline in condition to intensive chicken farming on the catchment.
The population of white-bellied heron in Bhutan continues to grow. Across 14 habitats, 27 individuals were recorded this year, four more than last year. This critically endangered species has fewer than 60 individuals worldwide and is found only in the Himalayan region in Bhutan, north-east India and Myanmar. As this is a top predator, its presence indicates a healthy ecosystem. Threats to this species and its habitat include fishing, local activities, natural resource extraction, development, ecotourism and timber and firewood.
The oak processionary moth, an invasive species, is thought to be spreading across south-east England. The government has introduced new legislation which aims to control the movement of oak trees in south-east England due to this rise in moth numbers. The toxic moths feed on the leaves of oak trees, affecting the health of oak trees by weakening them, making them more vulnerable to pests, diseases and drought.
Farmers are warning that England’s hedgerows are under threat from funding cuts. The transition to post-Brexit farming payments may mean that schemes to protect hedgerows could be lost. These habitats are vital for a number of species, including mammals, birds and pollinating insects, as they provide both food and shelter. The EU paid farmers under its subsidy scheme to keep hedgerows on their land, but they had to meet certain standards such as not ploughing to the base of hedgerows; not using fertilisers or pesticides within two metres of them; and not cutting hedgerows between 1st March and 31st August without good cause due to nesting birds. The government is ending these requirements by the end of the year.
15-million-year-old giant wombat skeletons have been uncovered in Australia. A new paper analysed the various features of these fossil bones to reveal the overall size and shape of the animal, its lifestyle and surrounding environment, as well as what kind of movements the animal was capable of. The research showed that this species, known as Nimbadon, spent some of its time suspended from tree branches like a sloth, grew in periodic spurts and had opposable thumbs. They are currently studying the enamel microstructure of Nimbadon’s teeth to determine its diet.
A program to plant 20 million trees in Australia prioritised cost-saving over gains for the environment, according to new research. Beginning in 2014, the program was aiming to improve native vegetation, support a richness of plant and animal species and reduce greenhouse gases. However, funding decisions were largely driven by ‘value for money’ considerations, with projects where the cost per tree was less than A$5 far more likely to be funded than projects where a tree cost more than A$10, undermining the benefits for both threatened species and the climate.
Extinction risk
A lack of large prey in Nepal may be the reason behind the rise in human-tiger conflicts. The wild tiger population has nearly tripled in the past 12 years but this has led to an increase in conflicts, with tigers in Bardiya National Park frequently preying on livestock in nearby settlements. Tigers in Parsa National Park, however, have access to large prey such as wild water buffalo and guar wild cattle, and researchers found no traces of livestock in their diet.
Trapping is holding back the speed of bird recovery in the Harapan Forest, Sumatra, Indonesia. A new study has found that the decade of protection and natural regeneration has helped bird populations increase in this forest, but wild trapping is preventing the full results of reforestation efforts. 45.1% of 122 bird species showed a notable population increase from 2009 to 2018, but 16.2% faced intensified trapping pressure.
Climate change
For the first time, wind is now the main source of UK electricity. In the first three months of 2023, wind turbines generated more electricity than gas, with a third of the country’s electricity coming from wind farms. There was also a record period for solar energy generation. While there is still a long way to go, this is a step in the right direction to meet the UK’s aim for all its electricity to have net zero emissions.
Frogs in Puerto Rico are croaking at a higher pitch due to global heating. The coqui frog appears to be decreasing in size due to the warmer temperatures, which is causing their croaks to become more high-pitched. Researchers are warning that if the trends continue, the temperature could become too high for certain amphibians to survive.
A new report claims that the UK could unlock £70bn a year in renewable energy. Generating more green electricity to meet the UK’s climate targets could create an additional 279,000 jobs, supporting a total of 654,000 jobs. If Britain’s clean electricity generation increased 50% above its current projections for 2050, it could be capable of exporting £17bn of green electricity to Europe annually. This could attract trillions in global private investment, doubling the £35bn a year economic benefit forecasted for its current path. To do this, government policymakers must remove barriers hampering the UK’s green energy ambitions, such as making sure the UK has enough batteries to store its renewable electricity and retrofitting commercial buildings to improve the UK’s energy efficiency.
Conservation
A Cornish farm is launching a project to triple the UK’s temperate rainforest. The Thousand Year Trust is being launched this year by a veteran who is now transforming his 120-hectare hill farm on Bodmin Moor into the largest rainforest restoration project in England and Wales. Working with local farmers, landowners and other charities to identify land suitable for this habitat, the charity has the ultimate aim of tripling Britain’s surviving rainforest to 1m acres over the next 30 years.
Seabird conservation is mostly working, according to a comprehensive new data set. Researchers compiled a data set of 851 seabird restoration events over the last 70 years, spanning 551 locations and targeting 138 seabird species. Forty-nine events used translocation, while 802 used social attraction, such as decoys, bird sound recordings and other devices aiming to lure birds to a new place. While the result of each project depended largely on the species and circumstances, most were successfully completed.
Policy
An unprecedented €2.2bn drought response plan has been approved in Spain. The package of measures includes €1.4bn in funds to tackle the drought and increase water availability, and €784m to help farmers maintain production and avoid food shortages. The €1.4bn will be spent on building new infrastructure, such as desalination plants, doubling the proportion of water that is reused in urban areas from 10% to 20% by 2027, and subsidising those whose irrigation water supplies would be reduced.
An abundance of urban honeybees adversely impacts wild bee populations. By comparing bee population data collected from sites around the island of Montreal in 2013 to data collected at the same sites in 2020, a new study argues that the rapid growth in urban honeybee-keeping in recent years may be negatively impacting nearby wild bee populations. The researchers believe that small bees with limited foraging ranges may be particularly at risk. As honeybees are not native to the region, they are in competition with the almost 180 other species for resources.
The habitat for Asian elephants has shrunk by almost two-thirds. Around 3.3 million sq km of habitat has been lost since 1700, according to a new study. China has lost 94% of its suitable elephant habitat, while India has lost 86% and Bangladesh 72%. Thailand, Vietnam and the Indonesian island of Sumatra have lost half of their suitable habitat. The study noted a trend of converting landscapes to more heavily human-dominated spaces but did not look into specific reasons for the habitat loss in each country.
A report has found that the UK is failing to honour its net zero farming pledges. The projected emissions drop for agriculture and land use are 58% below the target of the original net zero plan. This gap is comparable to the emissions of the entire UK building sector. Additionally, the total projected emissions benefits from tree planting, from now until 2037, are 85% lower than previously claimed, with the planting rates currently half of what are needed to be in line with net zero.
Spain is bracing for a record April temperature of 39°C. The government has warned people to take precautions as they face droughts and temperatures 7-11°C above average for this time of year. The country has been in drought since January last year. Last year, Spain experienced a series of heat waves, which were accompanied by forest fires that burned hundreds of thousands of hectares.
Wildlife crime
The illegal killings of birds of prey has led the Peak District national park to end an agreement between grouse moor managers and bird conservationists. The partnership, which was set up in 2011, sought to restore bird of prey populations across the park. Due to the continued illegal persecution targeting some of these species, the park is now looking for alternative ways to ensure birds of prey have a future in the area.
The Welsh Government has announced £11m for conservation projects that help Wales’ endangered wildlife. Nine new large and 17 medium projects will benefit from the last round of this Nature Networks funding package, helping to strengthen the resilience of Wales’ seas, forests and grasslands. One species to benefit is the Atlantic wild salmon, which experts say could disappear from Welsh rivers within the next two decades.
Brazil’s government has recognised six Indigenous lands. Out of 733 Indigenous territories, 496 are now recognised by the state, with the remaining 237 in different stages of the demarcation procedure. The current government is aiming to demarcate the highest number of Indigenous lands possible, not only because it is their right, but also to reach zero deforestation by 2030. Between 1990 and 2020, only 1% of native vegetation area was lost in lands demarcated or waiting demarcation. In comparision, private areas lost 20.6%.
A grey-headed lapwing has been spotted in Northumberland, UK. The species, which is normally found in India, China and Japan was spotted in England this week. It is thought to be the first sighting of the wader in the UK, with only five recorded sightings of the bird in Europe and western Asia in recent years.
Artificial nests raise hopes that golden eagles will be able to breed in southern Scotland. Two eyries were placed high in trees on a private estate near where three young eagles have been spotted. More than 17 privately owned estates support the South of Scotland Golden Eagle project and a series of translocations have increased the area’s population from a few pairs to 38. This is the highest number recorded for three centuries.
New data shows that 48% of UK bird species declined between 2015 and 2020. Woodland birds were shown to be faring the worst, with a 12% decline. The Environment Act passed into law in 2021, requiring a halt in species decline by 2030 but campaigners believe radical changes to government policy are needed if this target is going to be met.
The number of critically endangered fish species in Australia has doubled. Nine new species are now thought to be on the brink of extinction with calls for urgent action to control invasive freshwater species. Invasive trout have caused the ranges of many of these fish to be reduced to extremely small areas, with many only having one population left.
Climate change
The UK’s insulation scheme would take 300 years to meet government targets to reduce fuel poverty, according to critics. The Great British Insulation Scheme aims to insulate 300,000 homes a year over the next three years but does not go far enough to reach the 19 million homes that need better insulation. Home insulation grants are thought to be a crucial part of the government’s plan to have a net-zero economy by 2050.
Global ocean surface temperatures are at the highest since records began. The average temperature is at around 21.1C since the start of April, with the previous highest being 21C in 2016. This rise in temperature will likely lead to more extreme weather and marine storms, as well as polar ice caps melting and coral bleaching.

Wildlife crime
Roughly 1,000 pounds of illegally caught shark was seized in Texas. A recent study shows that humans are to blame for the 70% decline in sharks and rays, and that overfishing must be stopped or they could go extinct. Texas banned the trade of shark fins in 2015 but the state has long been a hot spot for shark fishing and trade.
Ospreys are being reintroduced to Ireland, more than 200 years after they were declared extinct. The species has not bred in Ireland since the 1700s but, after years of lobbying, the National Parks and Wildlife Service has agreed to reintroduce Osprey this year. A report from last year showed that 25% of Irish birds are in severe decline, with 37% more showing moderate decline. There are now calls to reintroduce more birds that are now extinct in Ireland.
People are being warned to leave capercailies alone, as this endangered bird stops breeding when disturbed. This species, whose Scottish population consists of only 542 individuals, is on the brink of extinction. It is a criminal offence to disturb capercallie while they are lekking (where males gather to display and fight for the attention of females), nesting or raising young. A birdwatcher was even arrested and charged last year for disturbing them.
Climate change
The hot, dry summer of 2022 has had a major impact on some UK butterfly species. The new study was conducted by Butterfly Conservation, the UK Centre for Ecology & Hydrology, British Trust for Ornithology and Joint Nature Conservation Committee. It showed that species such as the green-veined white, small white, small tortoiseshell, peacock and brimstone experienced greatly reduced numbers following the widespread drought. This is thought to be due to insufficient food for the caterpillars as food plants withered and died in the drought conditions.
The net zero strategy shows that the UK will miss its 2030 emissions cuts targets. According to the government, its policies will only achieve 92% of cuts required, but experts think that is a ‘very generous reading’. The UK has a legally binding requirement to reach net zero emissions by 2050, and it commited under the Paris agreement to cut emissions by 68% by 2030 (compared with 1990 levels). The new strategy is a mix of wins and losses: it requires car manufacturers to ensure 22% of their car sales and 10% of van sales must be of electric vehicles by 2024, but does not lift the ban on onshore windfarms and contains little reference to agriculture.
Policy
A new multi-million pound grant scheme has been launched by Natural England to help rare and threatened species, such as water voles, curlews and natterjack toads. The Species Recovery Programme Capital Grant Scheme will provide projects with £18 million over two years, delivering targeted conservation action through the creation and improvement of specific wildlife habitats, conservation translocation, research and creating solutions to address species decline.
Scientists have found the deepest fish ever recorded at 8,300 metres in the Izu-Ogasawara trench near Japan. A team made up of researchers from Western Australia and Tokyo captured footage of the animal, an unknown snailfish species belonging to the genus Pseudoliparis. Two other snailfish, Pseudoliparis belyaevi, were also filmed at a depth of 8,022m. At this depth, the pressure is 800 times greater than at the surface; snailfish are adapted to live at these high pressures by not having swim bladders and they have a gelatinous layer instead of scales.
A newly described leafless orchid in Sri Lanka has been named. The species was found in a lowland wet zone forest and has been named Gastrodia pushparaga, after a precious yellow sapphire commonly extracted from the same district. This is the third Gestrodia species found in Sri Lanka, the other two being discovered in 1906 and 2020.
An invasive snail is helping an endangered bird in Florida. The snail kite is bouncing back from the threat of extinction, due to the abundance of a new food source. Their original food source, a local apple snail, suffered severe declines due to droughts in the early 2000s. This new non-native island apple snail is five times bigger than the original species; continued monitoring of the snail kite has shown that their bills are getting bigger to accommodate this larger food source.
The Yangtze finless porpoise population has increased for the first time. The latest census conducted by the Chinese Ministry of Agriculture and Rural Affairs shows that the population has increased by over 23 percent in the past five years, from 1,012 to 1,249. This is seen as evidence that the conservation effort for the world’s only freshwater porpoise is effective.
Humans are altering the diet of the Tasmanian devil. Human-modified landscapes may be narrowing the diet of this species and accelerating their decline, according to a new study. Devils living in human-impacted areas, such as cleared land, fed on mainly medium-sized mammals. However, in undisturbed habitats, their diet was broader, including smaller animals such as birds.
There is a drought risk to multiple English regions after a dry February. England had its driest February for 30 years, with some rivers at their lowest on record. Scientists are warning that South West England and East Anglia are at risk of drought unless ‘unseasonably sustained rainfall’ occurs in the coming months.
Global fresh water demand will outstrip supply by 40% by 2030, according to experts. The new report calls for governments to stop subsidising the extraction and overuse of water, and for industries from mining to manufacturing to overhaul any wasteful practices. The report has set out seven key recommendations, including scaling up investment in water management and pricing water properly.
Scientists have delivered the ‘final warning’ on the climate crisis. The final part of the sixth assessment report by the Intergovernmental Panel on Climate Change (IPCC) was set out on Monday. This comprehensive review of the knowledge of the climate crisis took eight years to compile and has one clear message: act now, or it will be too late. The report, called the synthesis report, will most likely be the last assessment while the world has a chance of limiting global temperature rises to 1.5°C.
Policy
Ecological emergency has been declared by councillors in South Tyneside, UK. This is part of efforts to boost the biodiversity in the borough, while also safeguarding the natural environment. This declaration has set out 11 pledges which will increase ‘eco-literacy’, develop ‘member champions’ for biodiversity and ensure that council strategic decisions and policies will consider and maximise nature recovery.
