Loss of animal biodiversity is impacting the survivability of some plants. Species that rely on animal-facilitated dispersal are unable to keep up with climate change as they cannot disperse their seeds far enough to shift their geographic ranges, due to the decline in biodiversity of birds and mammals. Published in Science, a new study has shown that 60% fewer seeds are being dispersed far enough to reach newly suitable habitats, with North America, Europe, South America and Australia the most affected.
Norway has blown up a dam that blocked the Tromsa River for more than 100 years to free up migratory routes for fish. The dam has not been used for over 50 years and the river, which feeds into Norway’s biggest lake, will allow fish in the area to thrive, including grayling, Alpine bullhead and common minnows. Prior to this, the fish were only able to live and spawn in 950 metres of the river. Now that the dam has been removed, these species will be able to swim 10km upriver.
A new study suggests that the sixth mass extinction is currently underway. The planet has undergone five major extinction events but, according to the study published in Biological Reviews, the current one is entirely caused by human activities. Since the year 1500, between 7.5% and 13% of 2 million known species could have already been lost, with drastically increasing rates of species extinctions and declining abundances. However, a bias towards evaluating birds and mammals and an under-reporting of other fauna such as invertebrates may be leading to many denials that the current rate of species die-offs amounts to a mass extinction.
Chester Zoo helps reintroduce ‘extinct fish’ to Mexico. The tequila fish (Zoogoneticus tequila) is a small species of goodied fish that disappeared from the wild in 2003 due to water pollution and the introduction of invasive fish species. A team of conservationists from Chester Zoo and the Michoacana University of Mexico have returned over 1500 fish to a number of springs in the Teuchitlán River in south-west Mexico, with the fish now thriving and breeding in the river. This project is hoped to have created a blueprint for future reintroductions of other endangered fish species.
Baby hellbender salamanders hatch at the St. Louis Zoo in Missouri, with hopes of restoring this species in the wild. The population of this species in Missouri has declined by over 75% since the 1980s, as they’re sensitive to environmental changes caused by climate change, pollution, disease and habitat modification. Chytridiomycosis, the deadly amphibian disease linked to massive worldwide amphibian die-offs, has also been detected in Missouri hellbenders. These captive-bred eggs will be carefully monitored and the hatchlings will be released into the wild when they are two years old.
19 bird species have been added to Nepal’s list of nationally threatened birds in the past decade. As of 2018, this list consists of 168 birds, with aquatic species making up 49 of these. The nationwide count of aquatic birds is taking place between 1st and 16th January, and will show the latest condition of the threatened bird species in Nepal. This increasing number of threatened species is thought to be due to a number of issues, including shrinking forest cover and wetlands, habitat destruction, chemical poisoning, land fragmentation, climate change and hunting.
This is a Technical Support Bulletin from Wildlife Acoustics regarding problems that can occur when using the SM4 family of recorders with certain SD cards.
Overview
A number of customers have recently reported deployment problems when using SanDisk Extreme and SanDisk Extreme Pro SDXC flash cards with their Song Meter SM4 family recorders. The issue can affect all Song Meter SM4 family products including the SM4, SM4TS, SM4BAT-FS, SM4M, and SM4MU (but excluding SM4BAT-ZC).
The failure generally manifests with schedules that make continuous back-to-back one-hour recordings and can result in recordings being lost. Corrupted .WAV recordings with a 256KB length and/or many .sm4dump files on the card are both indications. The issue only rarely affects schedules with short duty cycle recordings such as 10 minutes on the hour, or on triggered recordings on the SM4BAT-FS.
Note: Many of the above symptoms are normal at the end of a deployment as batteries fail. What is unique to this issue is it can occur while the batteries are fresh.
Solution
Wildlife Acoustics have released firmware version 2.3.3 that corrects this problem and may improve interoperability with other flash cards as well. We strongly advise customers to update to this latest version as soon as possible whether you are seeing issues or not. The firmware is available on the Wildlife Acoustics website after you log in to your account here: https://www.wildlifeacoustics.com/account/downloads/sm4.
Firmware version 2.3.3 also fixes an unrelated issue, introduced with firmware 2.3.1, which could result in corrupted cards that are formatted in exFAT and have the “dirty bit” set (this indicates an issue with unmounting the card previously).
Note: If you experience card corruption, Wildlife Acoustics have tools that can possibly recover recordings off the card. Contact their support team using the details below for more information.

A UK campaign, headed by Professor Dave Goulson, has called upon the government to ban the use of peat in garden compost by the end of 2021.
In 2011, voluntary targets were set by the government with the aim of ending the domestic sale of peat-based composts by the end of 2020. But, in a recent letter to the environment secretary, George Eustice, Goulson explains that these targets have been an ‘abject failure’. The letter, which has been signed by a long list of notable conservationists, scientists and gardeners – including Alan Tichmarsh, Isabella Tree and Kate Bradbury – goes on to suggest that banning peat-based composts before the COP26 climate conference is a vital step in demonstrating the UK government’s dedication to addressing the climate crisis.
Why is peat important?
Globally, peatlands store half a trillion tonnes of carbon; this is twice as much as is stored in the world’s forests. In the UK alone, peatlands hold more than three billion tonnes of carbon although, worryingly, only 20% exist in a natural or near natural state. Peatlands also provide important habitat for many species of plants and animals and play a critical role in reducing flooding.
As well as the extraction of peat for use in the garden trade, these areas are under threat from overgrazing, draining (so that land can be made suitable for farming), and burning of the surface heather, particularly on grouse shooting estates.
Peatlands grow from the slow accumulation of dead plant material in wet terrestrial habitats and take an incredibly long time to form. When the peat is extracted or damaged, the stored carbon that has built up over centuries is released into the atmosphere. Because of this, the UK’s peatlands are now acting as a net carbon source, rather than an environmentally critical store.

How can I help?
As a gardener and consumer, one of the most important things you can do is to commit to only buying composts that are peat-free. Or, better still, if you have the space, try making your own from kitchen and garden waste. As stated in Goulson’s letter ‘Unearthing this precious store of carbon to use in the garden is needless, given that there are high-quality peat-free alternatives available’. Following a survey conducted by the Wildlife Trusts, only two garden retailers declared an end-date for peat sales: Travis Perkins in 2021 and Wickes by 2025. Other retailers, including B&Q, Asda and Lidl said they were committed to phasing out peat products but gave no date.
For anyone purchasing plants from nurseries, the Dogwood Days blog provides a comprehensive list of plant nurseries that are peat-free on site and/or committed to sourcing peat-free plants.
Since its launch in 1989, British Wildlife has established its position as the leading natural history magazine in the UK. NHBS first took on responsibility for publishing British Wildlife in 2016, and in August this year we were excited to announce that the magazine will be expanding, with the addition of two extra issues per volume. Here, British Wildlife’s Editor talks more about this change and highlights a small selection of the many fascinating articles published in recent issues.
This autumn has been a busy one for British Wildlife as, after 31 years as a bimonthly, we have begun our move to publishing eight times per year.
The main driver for this change has been the sheer volume and quality of articles we have received in recent years, and the sense of frustration at watching these sit on our hard drives for many months before they make it to print! The move to eight issues will speed up the publication process and, we hope, leave us better placed to track the most important developments in nature conservation. In a time of such rapid change, both in the fortunes of our wildlife and the world of environmental policy, the need for informed commentary and expert analysis is greater than ever. In British Wildlife, we will provide a forum for discussion of these topics while continuing, as always, to showcase the delights of natural history in Britain and Ireland.
Our additional space also provides the opportunity to bring further variety to some of our regular features, including through occasional contributions from guest columnists and expanding the coverage of our ever-popular wildlife reports section (see the October issue for our debut plant galls report, and look out for further additions over the next year).
The first November issue of British Wildlife
As part of the expansion, last week saw our first ever November issue go to the printers. Subscribers can look forward to articles on a varied mix of subjects, including:
the story of discovery of autumn swarming by bats
the potential to create an alluvial floodplain woodland – a habitat lost from Britain – in the Usk Valley, in Wales
the conservation of one of Britain’s largest and rarest spiders, the Fen Raft Spider
the diverse wildlife and habitats of Muir of Dinnet National Nature Reserve, in Aberdeenshire
The limitations of photographs for identifying insects and the need for specialist recording
A number of other fascinating topics have appeared in recent months.
Highlights in October included an overview of the conservation and biology of the Critically Endangered European Eel – the most heavily trafficked wild animal in the world – along with a summary of the difficulties brought upon the conservation sector by the COVID-19 pandemic, and a detailed behavioural study of the common, yet often overlooked, Speckled Bush-cricket.
British Wildlife, August 2020
Our August issue explored the topic of island biogeography through the lens of the Scilly Isles and their unusual wildlife, the spectacular effect of beavers on wetland habitats, and the remarkable world of hybridisation between orchid species.
And in June, we covered the folklore and natural history of the Jackdaw, the amazing diversity of the Ardeer Peninsula, which is currently threatened by development, and the identification and biology of Britain’s ten species of froghopper, or ‘cuckoo-spit insect’.
The above includes just a small selection from recent issues – for a full list of articles and other features, visit the British Wildlife website.
Individual back issues of the magazine are available to buy through the NHBS website, while annual subscriptions start from just £35 – sign up online here.

On 2nd September last year, a terrible fire destroyed the National Museum of Brazil in Rio de Janeiro. Alongside the vast collection of irreplaceable natural history specimens, the fire also destroyed books and equipment used by the Museum’s researchers for ecological research and wildlife conservation.
Thankfully as museum curator, Débora Pires, wrote shortly after the incident: “The brains did not burn; we are working with a positive agenda!”
A selection of books kindly donated
NHBS were approached by our former director Alan Martin, who provided a list of products which the malacology, arachnology, entomology and lepidoptera departments needed to get back on their feet. Alan, now secretary of the Brazilian Atlantic Rainforest Trust (BART) has close links with many researchers at the museum.
Following this, we decided to coordinate an effort to provide the items that are most critical to their research. We contacted suppliers asking them to contribute and we agreed to supply our own manufactured products, and cover shipping costs of all donated items.
The response from suppliers was fantastic, as the majority were happy to donate all, or most of the items requested. We would like to give huge thanks those who have donated so far: Elsevier, BIOTOPE Parthenope, Brunel Microscopes Ltd, BugDorm, CABI Publishing, Harvard University Press, the Royal Museum for Central Africa, Watkins & Doncaster and finally EntoSphinx. So far, we have received just over £2,000 worth of items, with more to follow.
A selection of items that are being sent in the first shipment.
“I’m really sorry to hear such devastating news. This is truly awful and it’s good to see you are providing such great support to them. We would be happy to send out the [requested] book gratis.” – Linda Jackson, Elsevier

On 6th November, a date that marks the 800th anniversary of the 1217 Charter of the Forest, a new Charter for Trees, Woods and People will be launched. Read on to find out more, including the 10 principles of the Tree Charter and information on how to get involved.

What is the Tree Charter?
Led by the Woodland Trust, the Tree Charter brings together more than 70 organisations in a united effort to protect the rights of and relationships between trees and people in the UK.
The Charter will be launched on 6th November at Lincoln Castle. This date marks the 800th anniversary of the historic 1217 Charter of the Forest which set out the rights of the people to use the Royal Forests in England. Lincoln Castle is home to one of the only two surviving copies of this document, making the timing and location of the launch doubly momentous.
The new Tree Charter is intended to influence policy and practice by settings out the practical roles and responsibilities of individuals, businesses and government in the UK and will also provide a voice for the hundreds of thousands of people that it represents.
The Charter consists of 10 Principles which cover different aspects of protecting and celebrating our trees. During National Tree Week (beginning Saturday 25th November) ten Tree Charter poles – one for each of the 10 Principles of the Charter – will be unveiled across the UK.
The 10 principles can be read in detail below, along with the locations of the charter poles.
The 10 Principles of the Tree Charter (Reproduced from https://treecharter.uk)
1. Thriving habitats for diverse species (New Forest Visitor Centre) Urban and rural landscapes should have a rich diversity of trees, hedges and woods to provide homes, food and safe routes for our native wildlife. We want to make sure future generations can enjoy the animals, birds, insects, plants and fungi that depend upon diverse habitats.
2. Planting for the future (Burnhall, Durham) As the population of the UK expands, we need more forests, woods, street trees, hedges and individual trees across the landscape. We want all planting to be environmentally and economically sustainable with the future needs of local people and wildlife in mind. We need to use more timber in construction to build better quality homes faster and with a lower carbon footprint.
3. Celebrating the cultural impact of trees (Bute Park, Cardiff) Trees, woods and forests have shaped who we are. They are woven into our art, literature, folklore, place names and traditions. It’s our responsibility to preserve and nurture this rich heritage for future generations.
4. A thriving forestry sector that delivers for the UK (Sylva Wood Centre, Abingdon) We want forestry in the UK to be more visible, understood and supported so that it can achieve its huge potential and provide jobs, forest products, environmental benefits and economic opportunities for all.
Careers in woodland management, arboriculture and the timber supply chain should be attractive choices and provide development opportunities for individuals, communities and businesses.
5. Better protection for important trees and woods (Sherwood Forest, Nottingham) Ancient woodland covers just 2% of the UK and there are currently more than 700 individual woods under threat from planning applications because sufficient protection is not in place.
We want stronger legal protection for trees and woods that have special cultural, scientific or historic significance to prevent the loss of precious and irreplaceable ecosystems and living monuments.
6. Enhancing new developments with trees (Belvoir Wood, NI) We want new residential areas and developments to be balanced with green infrastructure, making space for trees. Planning regulations should support the inclusion of trees as natural solutions to drainage, cooling, air quality and water purification. Long term management should also be considered from the beginning to allow trees to mature safely in urban spaces.
7. Understanding and using the natural health benefits of trees (Alder Hey Children’s Hospital, Liverpool) Having trees nearby leads to improved childhood fitness, and evidence shows that people living in areas with high levels of greenery are 40% less likely to be overweight or obese. We believe that spending time among trees should be promoted as an essential part of a healthy physical and mental lifestyle and a key element of healthcare delivery.
8. Access to trees for everyone (City Forest Park, Manchester) Everyone should have access to trees irrespective of age, economic status, ethnicity or disability. Communities can be brought together in enjoying, celebrating and caring for the trees and woods in their neighbourhoods. Schoolchildren should be introduced to trees for learning, play and future careers.
9. Addressing threats to woods and trees through good management (Land Craigs) Good management of our woods and trees is essential to ensure healthy habitats and economic sustainability. We believe that more woods should be better managed and woodland plans should aim for long term sustainability and be based upon evidence of threats and the latest projections of climate change. Ongoing research into the causes of threats and solutions should be better promoted.
10. Strengthening landscapes with woods and trees (Grizedale Forest, Cumbria) Trees and woods capture carbon, lower flood risk, and supply us with timber, clean air, clean water, shade, shelter, recreation opportunities and homes for wildlife. We believe that the government must adopt policies and encourage new markets which reflect the value of these ecosystem services instead of taking them for granted.
How to get involved:
• Firstly and most importantly – sign the Tree Charter. By adding your signature you will show your support for the principles stated in the charter and will join the growing list of 1000s of people who want to see trees protected, shared and celebrated in the UK. The Woodland Trust will plant a tree for every signature on the list and will also use your contact details to keep you up to date with the campaign.
•Join a local Charter branch. Join an existing group or, if there isn’t one near to where you live, set up your own. Charters can apply for funding from the Woodland Trust and will receive free copies of the seasonal newspaper LEAF! As a charter branch you will also be able to apply for a Legacy Tree. 800 of these trees are being planted around the UK as a living reminder of the 800 years between the original 1217 Charter of the Forest and the 2017 Tree Charter. Each tree will be supplied with a commemorative plaque.
•Explore some of the locations on the Tree Charter Art and Heritage Trail. All locations are displayed on a beautifully illustrated map by Adam Dant, highlighting the role that trees have played in the culture and heritage of our country.

The accumulation of stacks of pallets is an unavoidable part of working in a fast paced and varied retail environment. So when we were contacted by Keith Grant from the Slapton Ringing Group to ask if they could take some off our hands, we were both delighted to agree and eager to learn about the site where they would be put to use.
The Slapton Ringing Group is based at the Slapton Ley National Nature Reserve. This beautiful site is located on the south coast of Devon and contains the largest lake in the south west, separated from the sea by just a narrow shingle bar. Its location, together with the unique habitat conditions, makes it an extremely important place for local and migrating bird populations.
A job well done. The completed walkway leading to the ride. Photo by David Price.
The Slapton Ringing Group have been surveying birds at Slapton Ley since the 1960s, and for the last six years the site has been designated as a BTO Constant Effort Survey (CES) Site.
A regular rotation of willow cutting is undertaken at the site, which maintains the vegetation and helps to avoid major changes in species composition. A carefully constructed pallet walkway allows access to the ringing rides for the volunteers that meet here regularly throughout the ringing season.
The pallets salvaged from NHBS were used to replace old ones which have an obviously limited lifespan due to the constantly wet conditions. It is a pleasure to know that some of our “waste” is being used to support such a fantastic and long-running project.
For more information about bird ringing in Devon, take a look at the Devon Birds website.
British Wildlife, the magazine for the modern naturalist, is now published by NHBS.
