In the forthcoming Winter 2021 issue of Conservation Land Management (CLM) magazine Jenny Price and Lyndsay Wayman-Rook describe how the Old Chalk New Downs project in Kent has been trialling biodegradable cardboard tree guards as an alternative to plastic. Here you can read a summary of the article.
The main purpose of a tree guard is to protect newly planted trees from browsing, but they also provide other benefits; they create a more favourable microclimate that helps to promote the growth of young trees and protect the plants from wind, competing vegetation, herbicides and water loss. Wooden and wire tree guards have been in use since the 1820s, but it wasn’t until the 1980s that plastic versions were first used. As a cheaper material compared to alternatives, plastic is now widely used for guards in planting schemes.
It has been predicted that between 1980 and 2020 over 200 million plastic tree guards were used, and with the UK government’s ambitious target to increase woodland cover by 19% by 2050, the rate of tree planting is sure to increase, as will the number of tree guards used. It is recommended that plastic tree guards are removed 2–3 years after their installation, but they are often left behind to degrade in the landscape, which can be both damaging to the wider environment (although the impacts of this are not yet fully understood) and to the tree itself. It is possible to recycle plastic polymer guards, but not if they have already started to break down or are contaminated.
Cardboard tree guards offer a viable alternative to plastic. Lyndsay Wayman-Rook and Hannah Simmons
The Old Chalk New Downs project, hosted by Kent County Council and funded by the National Lottery Heritage Fund, has been exploring alternative options to plastic tree guards. It first compared the costs of different materials, including plastic, cardboard and biodegradable plastic, and looked at the pros and cons for each guard type. For instance, one of the advantages of a cardboard guard is that it does not need to be removed after installation, but it may deteriorate a lot faster than other guard types, especially in particularly wet areas.
Biodegradable tree guard options Lyndsay Wayman-Rook
It was decided that cardboard guards would be used for this particular project, owing to their no-plastic design and availability. Between autumn 2019 and spring 2021, more than 9,000 trees with cardboard guards were planted across seven hedgerows at three different sites. How these fared was closely monitored, and the success rate of planting was high. One key aspect of this project was to gather feedback from landowners and contractors involved in sourcing and using the cardboard guards, and overall the comments were positive.
In the full article Jenny Price and Lyndsay Wayman-Rook discuss how the cost of tree guards made from plastic, biodegradable plastic and cardboard compare, and provide an in-depth overview of how cardboard guards performed when used for hedge planting, both in this project and in examples from elsewhere. They also include a summary of the feedback received from landowners and contractors, and clearly describe the advantages and disadvantages of different tree guard options.

This is the first article in our new Testing the Guide series, in which we test the usability and application of various guides. Feathers: An Identification Guide to the Feathers of Western European Birds is a guide to over 400 European bird species, with an innovative key that allows for exceptionally precise identification by colour, feather structure and shape. This book also provides information on collection and conservation methods, as well as the locations of feathers on birds, all of which are clearly explained and richly illustrated.
This guide discusses the characteristics useful for identification, such as feather measurements, size variations and flight and tail feather shapes and adaptions. Also included are examples of identifiable body feathers and a beginner’s exercise in the identification of feathers from some common species. There are also species descriptions, including passerines, aquatic birds and birds of prey. The sequence of which these species are described, within families or orders, does not follow the usual systematic order: the author has attempted to describe groups that may be confused in close proximity due to their similar morphological characteristics or their presence in the same habitats.
This is a large-format guide, which may limit the practicality of taking it into the field, but it does allow the presentation of different feathers to be done in the clearest way. Therefore, this guide is most useful when feathers are collected or photographed. The more than 300 illustrations and 400 photographs facilitate the identification of many different feathers, often reducing the need for further, independent research.
Using the guide
Several feathers have been gathered by our colleagues around the UK, with notes taken of the location, date and habitats in which they were found, to aid identification. The guide details best-practice methods for collecting, labelling and preserving the feathers, which we found particularly useful. As the author suggests that larger feathers are more likely to be identifiable, and body feathers are much harder to distinguish, we chose to use the largest or most distinctive feathers we had collected.
Feather 1
The largest feather in our collection was found on the edge of town in Bovey Tracey in south Devon. It is a large, rigid feather that is dark brown in colour, with a white coloured section on the inner vane and darker brown irregular bars that end in specking on the white section. Using one of the many useful figures within chapter 2 (p. 17), as well as following the key located in chapter 3, we identified it as a notched, or fingered, outer primary feather from the right side of the bird. As the pattern matched several of the colour criteria within chapter 4, the process of determining identification took a little longer than expected. Using the colour criteria 4, 5, and 7, we were able to determine the feather is from a diurnal bird of prey.
Using the table for diurnal birds of prey in chapter 8, we noted that the size of the feather (approximately 13.6in / 34.5cm) and the patternation matched several species, including the common buzzard (Buteo buteo), the rough-legged buzzard (Buteo lagopus) and osprey (Pandion haliaetus). Referring to a number of the many beautiful photo plates and our own research, it is most likely a feather from the common buzzard, given its distribution, habitat and that they are much more common in the UK than osprey. Using the table in chapter 5 (p84), the placement of this notched primary feather is most likely between P10-P8, although it can be as far as P6 or even P5.
Feather 2
Using the information in chapter 3 again, we were able to determine that this second feather is also a large feather, most likely from the left side of the bird, as the feather curves to the left when looked at from above with the base towards us. Following the key was more difficult for this feather, as the answers were not as clear. However, we determined that this feather is a rectrix, or tail feather. As the width of both vanes are similar (outer: ~1.3cm, inner: ~1.2cm, although there is some degrading along the edge of the inner vane that may be masking its original width), the feather was most likely located towards the centre of the tail. As the rachis (or shaft) is curved and not fully straight, however, it is unlikely to have been located directly in the centre.
The feather is rufous and dark brown, with an irregular bar pattern that sometimes resembles vermiculation and gradually breaks down into speckling, with a more rufous tip. As the size of the darker bars is smaller, it would be referred to as brown bars on a rufous background. Using the colour criteria list in chapter 5, the feather size (~24.2cm / ~9.53in) is within the range of several species. As the feather is not velvety, we could discount owls, diurnal raptors or nightjars. As the feather is narrow and elongated, the chapter suggested looking at falcons, but we found that it did not match any due to the pattern and pointed tip. We then researched each species or species group that the size matched and determined that the feather is most likely a tail feather from a golden pheasant (Chrysolophus pictus). This is an introduced species with several small, wild populations in areas such as East Anglia and in the Isles of Scilly, preferring dense woodland with sparse undergrowth. They can also be found in many aviaries and zoos, with a number of colour variations and hybrids, particularly with the Lady Amherst Pheasant (Chrysolophus amherstiae). Their feathers are often used by florists, as well as crafters to decorate heads, earrings, clothing and even lures for fly-fishing.
Feather 3
Bright, uniquely colour feathers have a higher chance of being identifiable to a species level. This feather was found in the wetlands around Chew Valley Lake reservoir in Somerset. The rigidity of this feather shows this is also a large feather, and the curve suggests it comes from the right side of the bird. Following the key in chapter 3, we determined that this is a secondary feather.
Using the colour criteria in chapter 5, the metallic dark blue colouration of the feather and the length (12.2cm / 4.8inchs) matches a number of species, but the handy colour plate on the next page allowed us to determine that this feather most likely came from a mallard (Anas platyrhynchos). The blue colouration makes up part of the speculum, the contrasting patch of colour on the bird’s wings. Referring to the species description and feather spread on pages 304-5, the feather is most likely a middle secondary, although exact positioning would be difficult to determine with a lone feather. The well defined dark blue colourations suggest between S3-S10. There are also a number of hybrid Anas species and the identification of these through feathers is unlikely.
Our opinion
There are several limitations to identifying feathers, as individual variability in size and colour are common amongst species, and feathers can be similar between species within the same family or that occupy the same habitat or niche. The author suggests that only a small fraction of feathers lost by birds are identifiable, therefore the practical applications of this guide are restricted. However, we were able to use this guide to identify many of our larger or more unique feathers, including the common kingfisher (Alcedo atthis), European goldfinch (Carduelis carduelis) and barn owl (Tyto alba).
It is relatively straightforward to identify where on the body the feathers come from and, while the feather can sometimes match several colour criteria, it is also quite easy to identify a list of potential species matches. From here, the size of the feather can help to narrow the list down, although this is not always possible. Using the various species descriptions and feather spreads in chapter 8, your own research and knowledge of the habitat and location that the feather was found in and the distinctive markings or colouration on the feather itself can all help you to identify your feather to species level. We also found that, while our first feather did not resemble the osprey spread in the guide, it did match feathers from other collection photographs we found in our own research. Therefore, while this guide is incredibly helpful in determining the type of feather and the list of possible species, we encourage researching any potential match both with the guide’s species descriptions and through independent research. Feathers: An Identification Guide to the Feathers of Western European Birds is a novel introduction to the world of identifying feathers, which can be an engaging and entertaining way to increase your knowledge of Europe’s birds.

Woodland is the next habitat in our NHBS Introduction to Habitats series. Broadly, these habitats are land that is covered with trees, but the term woodland encompasses a diverse group of habitats that can be rich in wildlife. They are a key habitat for many invertebrates, plants, birds, mammals and other species groups. Woodlands are also incredibly useful habitats, for instance by providing flood protection by holding back water in the soil, sequestering carbon dioxide and reducing local temperatures. They also help reduce soil erosion and regulate weather patterns, such as local rainfall and temperature. Woodland may also be beneficial to our health, as it’s thought that spending time in forests decreases blood pressure, reduces stress levels and boosts your immune system. However, studies are still ongoing into the validity of these effects.
The types of woodland habitat include, but are not limited to, ancient, broadleaved, coniferous, mixed and wet woodland, as well as temperate rainforest, Caledonian forest, wood pastures and urban woodland. Each can have defining criteria such as plant types, soil moisture levels, humidity levels and age. There are also semi-natural and plantation woodlands, which are classified based on the percentage of planted trees. There are several indicator species used to determine the type of woodland habitats, such as the violet click beetle (Limoniscus violaceus), which rely exclusively on ancient decaying beech and ash trees. Several of these habitats are UK Biodiversity Action Plan (BAP) Priority Habitats, which are a range of threatened semi-natural habitats that require conservation action.
What species can you find here?
Flora
While trees often define woodland, this is not the only type of flora in these habitats. Woodland habitats host 60% of all known vascular plant species. Wildflowers, grasses, sedges, ferns, mosses, fungi and lichen all occur in woodland habitats, although the species found varies depending on the abiotic and biotic conditions within the habitat.
Oak Tree (Quercus spp.)

Did you know that there are actually over 500 species of oak tree in the world? The dominant oak tree in the UK is the English oak (Quercus robur). The sessile oak (Quercus petraea) is the UK’s other native oak species, but there are many more non-native species here, such as the Turkey oak (Quercus cerris) and holm oak (Quercus ilex). Oak trees can be keystone species in many ecosystems, with one study finding that a single oak tree can host more than 2,300 organisms (data supplied by Natural Environment Research Council). Some of those don’t occur on any other tree species. Oak trees can also live to around 1,000 years old!
The wood anemone is an ancient woodland indicator species as they are slow-growing and take a long time to fully establish. Therefore, large patches show that the habitat has been relatively undisturbed for a long time.
They are a spring species, often appearing with bluebells, another ancient woodland indicator. This species has a star-shaped white flower, that can have a pink tinge. It has distinctive yellow anthers in the middle.
A type of crane’s-bill, herb-robert is a low-growing plant with pink flowers and a reddish stem. It is widespread across the UK and prefers shaded habitats, such as woodland. This plant has many traditional uses, such as treating headaches, stomach aches and nosebleeds. It is an important nectar source and food plant for many invertebrates, such as bees and the barred carpet moth (Martania taeniata).
Fungi
Woodland, particularly habitats with a high amount of deadwood and leaf litter, can be key habitats for a wide variety of fungi species. These species break down dead organic matter and facilitate the recycling of carbon and nutrients back into the soil. They are also food for many species, including a number of invertebrate species, and are used as nesting material, for both birds and invertebrates.
Also known as stag’s horn fungus and candlestick fungus, this species grows up to 6cm tall, with a black base, grey body and white tip that is often branched, resembling deer antlers. It is a common species within the UK and grows in groups on dead wood. It prefers broadleaf trees, often growing through moss.
Bird’s Nest Fungus (Crucibulum leave)
Bird’s Nest Fungus by Sven Gaedtke via Flickr (cropped)
This woodland fungus is so named as it resembles a bird’s nest filled with a number of ‘eggs’. These eggs are actually periodoles, structures that contain the spores. A yellowish membrane initially covers the cup, before eventually rupturing to reveal the periodoles once they’ve developed. The energy of raindrops disperses them, allowing the fungus to spread.
This species lives mostly in wet woodlands, feeding mainly on insects but also berries and seeds. Unusually for tit species, the willow tit digs into decaying wood to make nest holes. This is why older woodlands are so important for this species, as there is a higher abundance of decaying wood and trees. The willow tit is so similar to the marsh tit (Poecile palustris) that it wasn’t recognised as a separate species until 1897.
Small Pearl-Bordered Fritillary (Boloria selene)
Small Pearl-Bordered Fritillary by Janet Graham via Flickr
Woodlands are home to thousands of invertebrate species in the UK. The small pearl-bordered fritillary is widespread across Scotland and Wales but is more limited in England. Like many other invertebrate species, they have suffered severe declines in numbers. Its bright orange and black markings make it a striking butterfly, quite easily seen against the green and brown woodland background.
This unmistakable creature is one of the most well known of Britain’s wildlife, with its iconic black-and-white striped face, grey body and black stomach. Did you know that a large amount of their diet is earthworms? They also prey upon hedgehogs, small mammals, other invertebrates, toads and frogs, and also eat fruit, such as plums and elderberries. This species is fully protected by the law but is still threatened by culls in certain areas, due to its association with bovine tuberculosis.
Another iconic British species that use woodland habitats is the red squirrel! This native species is far rarer than its non-native cousin, the grey squirrel (Sciurus carolinensis), due to being out-competed for food and habitat. Also, grey squirrels transmit a virus called squirrelpox, which has little effect on them but frequently kills red squirrels. Because of this, red squirrels are being pushed out of their normal habitat range. They now only occur in parts of Scotland, northern England and isolated areas such as Anglesey.
This elusive species, also known as the ‘tiger of the Highlands’, may be functionally extinct in the wild, as the population is too small to be viable. Threats from persecution, habitat loss, interbreeding with feral and domestic cats, road collisions and disease mean that this species will not recover without serious conservation action. There are now captive breeding programmes in place and a record number of kittens were born in captivity in 2020, with plans for the first cats to be released back to the wild from 2022 onwards.
Threats
Britain is one of the least-wooded countries in Europe, with only 13% of our land covered in woods compared to Europe’s average of 44%. The main threat to woodland habitat is deforestation, often for development or agriculture. Population growth leads to an increased need for housing and infrastructure, particularly in urban areas, often at the expense of woodland. Natural woodland regeneration is not always possible, especially for ancient woodland, which takes hundreds of years to develop. Additionally, high deer populations, particularly in Scotland, are curbing much of the growth of young plants. This is a serious threat to woodland such as Caledonian forests and it is sometimes necessary to fence off areas to allow for new growth. For more information on deforestation, as well as the potential impacts of the COP26 summit, check out our blog: Climate Challenges: 4. Deforestation.
Reduced management also threatens woodland habitats. Traditional practices, such as coppicing, which involves cutting a tree to ground level to stimulate more growth, are now less common. This led to changes in woodland structures, reducing the diversity of growth, the amount of light that can enter the canopy and reducing habitat opportunities for animals. The lack of regularly felled trees or unwanted branches that used to rot down within the woodland reduces the availability of key habitats for invertebrates and small mammals.
Invasive and non-native species can also impact woodland habitats. For instance, new plantations of tree crops, which have replaced areas of native trees, are usually less suitable for native woodland species. Diseases and pests are also causing issues for UK woodland. For example, ash dieback is predicted to kill around 90% of ash trees in the UK, and Dutch elm disease has killed millions of elm trees over the last 40 years.
Further threats also include pollution, climate change and forest fires. For more information about this threat, check out our blog: Climate Challenges: 2. Forest Fires. With the combined pressures from many of these threats and without current and future conservation efforts and protection, the future could see the loss of these habitats as we know them.

For much of this year, we have been writing a series of articles looking at some of the toughest global climate crisis challenges that we are currently facing. This article looks at the local and global implications of deforestation and its relation to climate change.
Deforestation is the removal of forests and trees from an area, which is then used for non-forest purposes, such as urban development or agriculture. It has been estimated that, since 1990, 420 million hectares of forest have been lost globally due to deforestation. The main driver of deforestation is agricultural expansion, primarily for commercial ventures such as cattle ranching and palm oil and soya bean cultivation. Around the world, we are thought to lose around 4.7 million hectares of forest per year, but as some areas are regenerated through natural expansion or replanting of new forests, the rate of forest cutting is most likely higher. However, the rate that forests are lost cannot simply be offset by new forests elsewhere; it can take years for even naturally expanded areas to develop. During this time, populations of species particularly sensitive to change could be lost.
Combined with threats from fires, droughts, increasing storm intensity and frequency, pollution, forest degradation through disturbance and the use of chemical insecticides and herbicides, forest habitats are under extreme pressure.
What are the impacts?
Thankfully, the rate of forest loss has been decreasing. Despite this, deforestation is still having widespread, devastating effects on biodiversity, the climate, and our health and wellbeing. Forests are home to a huge variety of species, including invertebrates, which represent a disproportionately large percentage of all species found in forests, and around 60% of all known vascular plant species. These ecosystems also host 80% of all known amphibian species, 75% of all bird species and 68% of all mammal species.
Therefore, deforestation is a significant threat to biodiversity, particularly for more specialist species that are unable to inhabit other areas and those already vulnerable to extinction. Around 28% of all species assessed by the IUCN red list are threatened with extinction, with many of these species being forest dwellers, such as the bizarre-nosed chameleon (Calumma hafahafa), a critically endangered chameleon endemic to Madagascar. This species is thought to only live in montane humid forests within a range of less than 100² kilometres.
Not only does deforestation impact biodiversity, but it can also increase the risk of flooding. Without the presence of trees and their roots to stabilise the soil and slow the flow of water, the soil is more susceptible to erosion which in turn can lead to more surface run-off and less water being absorbed. The removal of trees also contributes to the emission of carbon dioxide and, as tree cover provides shade and slows the rate at which the land heats up, can lead to a rise in local temperatures. Further impacts include changing rainfall patterns and the availability of fresh water. This can have a detrimental effect on agriculture, urban areas and local communities that rely on these natural processes for their water.

Public health
Deforestation has been linked to an increase in the exposure of people to zoonotic diseases (diseases spread between animals and people), with viruses such as Zika and Nipah suspected to be associated with human disturbance of forests. We have all seen the impact zoonotic diseases can cause on public health. As widespread deforestation continues, many experts are warning about the health of those living nearby. Around 2 billion people rely on forests for shelter, food and water resources – deforestation threatens their livelihoods.
The impact of deforestation on soil erosion, rainfall patterns and flooding may also lead to food insecurity. Low nutrient soil will reduce yields, which could be devastating as populations grow and food demand increases. This in turn means more land for agriculture is needed to produce more food, resulting in further deforestation.
What is being done to prevent deforestation?
Many countries have laws attempting to manage forest clearing and promote more sustainable practices. For example, the UK government included measures to address deforestation as part of the new UK Environment Bill, which received Royal Assent in November 2021. The new bill will make it illegal for UK businesses to use key commodities that have not been produced in line with local forest protection laws and UK businesses that fail to eliminate ties with illegal deforestation from their supply chains will face fines. However, this still allows for links to legal deforestation which, in many countries, can be just as unsustainable and damaging as illegal deforestation.
Countries are also creating annual tree planting targets, such as Scotland, whose target increased to 12,000 hectares of newly planted trees in 2020 and will increase again in 2024/25 to 18,000 hectares. Public education, trade reforms, concerted efforts to tackle illegal logging, creating protected forest areas and granting Indigenous Peoples rights to their traditional forests are also ways shown to prevent deforestation.
Individual companies are also making efforts, such as planting trees for every purchase or donating to charities and organisations involved with reforestation and conservation. Several British firms have signed up to WWF’s forest campaign, pledging to make sure that their wood and paper is legally and sustainably sourced.
By making more sustainable lifestyle choices, there are several small ways you can make a difference, such as by recycling, eating less meat and being a conscious consumer. The latter can be achieved by checking whether the product you are buying comes from a company with strong environmental and sustainability policies. Additionally, using your items for longer can reduce the amount you buy and, therefore, reduces demand for the production of new products.

COP26 Deforestation Pledge
The Glasgow Leader’s Declaration on Forest and Land Use has been signed by over 100 world leaders, whose countries cover around 85% of the world’s forests. The pledge aims to halt and reverse deforestation and land degradation by 2030, while still allowing for sustainable development and inclusive rural transformation. Twelve nations, including the UK, USA and France, have pledged to collectively mobilise £8.75 billion of public funding over the next five years to help support developing nations. This pledge is backed by the commitment of over 30 major financial institutions to look at removing commodity-driven deforestation from their investment and lending portfolios by 2025.
However, this deforestation pledge still allows for the removal of forests, focusing on ending net deforestation, with forest loss being replaced “sustainably”. There are a number of ecological issues with this strategy, as new-growth or secondary forest is less able to support the same levels of biodiversity as primary forest, and the period of ecological succession for these habitats to develop can take decades. Therefore, while this large-scale pledge may be a step in the right direction, many forest habitats, such as ancient forests, will still be under threat from deforestation.

Summary
Deforestation is mainly caused by the clearing of land for urban and agricultural development. While annual rates are decreasing, it still poses a significant threat.
Forest habitats are home to a vast majority of all known species, such as birds, amphibians, reptiles, plants and invertebrates.
Deforestation can impact biodiversity, temperatures, flooding, soil erosion and public health.
While many countries are attempting to tackle deforestation, there is still much work that needs to be done. The COP26 pledge to halt and reverse global deforestation may be a step in the right direction, but it does not remove many of the threats to forest habitats.

The Bat Conservation Trust’s annual National Bat Conference, held online via Zoom from 29th–31st October, covered many aspects of bat conservation through a wide variety of activities and talks, including monitoring, surveying and development. We are extremely pleased to have sponsored this event and we were lucky enough to have been able to attend many of these sessions, including talks by Professor Tigga Kingston from Texas Tech University on the human dimensions of bat conservation, and Thomas Foxley, University of the West of England, who spoke about the role of landscape features in spatial activity patterns of greater horseshoe bats. We also attended a few of the amazing workshops that took place, such as Shirley Thompson’s gardening for bats.
Bat Conservation Trust update
Bat Conservation Trust also shared an update on their current and future work. Bats make up more than a quarter of all mammal species in the UK, but sadly, these species face many threats. Habitat loss and fragmentation, decreasing food resources, chemical use, disturbance to roosts and threats from cats have all led to a dramatic decline in bat populations over the last century. Diseases, wind farms, flypaper, artificial lighting and the presence and construction of roads also negatively impact.

Currently, Bat Conservation Trust supports a number of local bat groups, working with volunteers, scientists, industry and government on a range of projects. They focus on discovering more about bats, taking action to protect them, inspiring people to care about bats and strengthening their work by improving relevant skills and knowledge. Their programmes include a National Bat Monitoring Programme, education and engagement, the National Bat Helpline, Landscapes for Bats, and science and research.
During this update, Bat Conservation Trust spoke of the many ways they will be increasing their efforts to help bat populations, for example by increasing the spread of their monitoring programs and organising a petition regarding key amendments to the Environment Bill, including legally binding targets for wildlife recovery. Through new acoustic and monitoring approaches, they also aim to improve their evidence base and Bat Conservation Trust are also working towards improving their engagement with policymakers, the public and the media. Their Bat in Churches project has also been expanded to include training on bat care basics, surveying a church, the best architectural practices for bats and cleaning workshops.
One key scheme they are developing is the Bat Roost Tree Tag Scheme where recognisable tags are placed on trees that contain bat roosts. The aim of this is to make sure all trees that have been surveyed and found to contain bat roosts are easily identifiable. When woodland managers and workers see a tag on a tree, they will know to seek advice before proceeding with work. This will also give a significantly increased level of protection for ancient trees, which are vitally important for a large number of species.
Future events and how to get involved
The National Bat Conference was a very interesting and educational event, and it was wonderful to see such a wide range of knowledge and skillsets being shared through the many talks, activities and workshops throughout the weekend. If you missed out this time or would like to attend further events, the Bat Conservation Trust has a number of future events planned, including Spring into Action, Midlands Bat Conference and the East of England Bat Conference. More information about these and other events can be found on the Bat Conservation Trust website.
There are a number of ways you can help to support Bat Conservation Trust, such as by becoming a member or donating. You can also contact your local bat group, fundraise for bats or volunteer for their various projects. However you choose to get involved, you can make a real difference to the future of bats in the UK.
COP26, the 26th annual summit of the United Nations Climate Change Conference, has come to a close. This historic event ran from 31st October to 12th November and aimed to secure global net zero emission targets and keep the 1.5°C target within reach. It also discussed the need to adapt to protect communities and natural habitats, mobilising finance and working together to deliver key commitments. For more information on the lead up to this event, what net zero means and the 1.5°C agreement, read our blog: What is COP26 and Why is it Important? We also looked back on the first week of COP26 in our blog: Climate Challenges: COP26 First Week Update. In this article, we discuss an overview of the major outcomes of this event and how they might affect our efforts to combat climate change.

Key outcomes
A number of key pledges were launched and signed during COP26, including:
90% of the world’s economy now striving for net zero emissions, with many aiming for 2050.
The Glasgow Leader’s Declaration on Forest and Land Use intends to halt and reverse deforestation and land degradation by 2030, while also delivering sustainable development and promoting an inclusive rural transformation. This pledge has been signed by over 100 world leaders, covering around 85% of the world’s forests.
More than 100 world leaders have signed the Global Methane Pledge, a U.S. and EU-led commitment to reduce methane emissions by 30% over the next decade from 2020 levels.
The Breakthrough Agenda, a global initiative launched by the UK, aims to make clean technologies and sustainable solutions the most economical and appealing option for each emitting sector by 2030, with leaders committing to review progress annually, starting in 2022.
The Coal Pledge, signed by more than 40 countries, aims for nations to move away from coal power by the 2030s for major economies and 2040s for developing countries.
A $10.5 billion fund for emerging economies to switch to renewable energies will be supplied by the Global Alliance Group, a group of philanthropic foundations and international development banks. They intend to raise $100 billion in public and private capital.
Around 450 financial organisations, with a combined market capitalisation of $130 trillion, have agreed to shift their investments away from financing fossil fuel-burning industries and toward “clean” technology.
China and the U.S. have announced an agreement to work together to cut emissions and help the world stay within 1.5°C by cooperating on key areas, such as cutting emissions from transport, energy and industry.

Are they effective?
Many critics and climate experts are concerned that these pledges will not be enough to keep average global temperatures below 1.5°C above pre-industrial levels. There are calls for global leaders to do more to meet this goal, as exceeding it will see a worsening in the negative impacts of climate change, potentially putting millions of lives and livelihoods at risk. With countries such as Russia, China, India and Australia refusing to sign the methane pledge, and others, such as the U.S. and China, not signing the coal pledge, it is unclear how successful these agreements will be at tackling climate change. Despite signing the deforestation pledge, Indonesia has stated that it will not halt its developmental growth, which involves cutting forests for new roads and the cultivation of food crops. According to a spokesperson for UK Prime Minister Boris Johnson, this pledge does not forbid the cutting down of forests, but rather seeks to end net deforestation – forest loss must be “replaced sustainably”.
Replacing primary forest with new growth has a variety of negative environmental consequences. Primary, undisturbed, ancient forests are often highly complex ecosystems that support a variety of species, including many specialist species, and have an irreplaceable value. New-growth or secondary forest are less able to support the same level of biodiversity, as they may have significant differences in forest structure and species composition. Abiotic factors can vary during development, reducing the area’s suitability for the previous ecosystem. After a major disturbance, it can take decades for an area to develop into a climax community, such as a forest, through ecological succession. During many of these stages, many of the species that previously inhabited the primary forest will be unable to survive, and the community will most likely be made up of more disturbance-tolerant, generalist species that are often of lower conservation concern.
Once the stable climax habitat has developed, even if the new habitat is similar, the community structure may differ dramatically from the original. Certain plant or wildlife species may have been unable to re-establish due to the presence of new species or a reduction in resources, potentially leading to localised extinctions. It is unknown how long it takes for a secondary forest to develop the levels of biodiversity found in primary forests, but it could be several hundred years. Therefore, this form of “sustainable” deforestation might still result in extinctions and reduced biodiversity. These new-growth regions may be far less ecologically valuable than primary forest and, during much of the successional period, store significantly less carbon.
A deforestation policy that focuses on net deforestation rather than halting or severely limiting all deforestation, could potentially help to reduce world carbon emissions by stabilising, or even increasing global forest cover, but this does not address the whole picture. This policy allows for the continued negative ecological impacts of deforestation on biodiversity and vulnerable species, which could ultimately lead to countless extinctions.

Glasgow Climate Pact
Only effective implementation of pledges and tangible action, much of which has not been seen following previous promises of past summits, can ensure the success of COP26. The Glasgow Climate Pact is the agreement reached at COP26 and the first deal ever to explicitly plan to reduce coal. This document initially aimed to clarify and build on the Paris Agreement, proposing that countries agree to accelerate the phasing out of fossil fuels and for developed countries to double their climate finance commitments for funding adaptation. However, many demonstrators throughout the two-week event have called for bolder commitments and stricter accountability to combat climate change, followed by appropriate and effective action.
The first draft of the document was criticised for a variety of reasons, including a lack of financial aid for developing nations and the need for clearer commitments to force countries to increase their emissions cuts. The second draft retained the core demand to return to the negotiating table next year to improve countries’ national emission reduction plans, but included even softer language. COP26 President Alok Sharma stated he was “deeply sorry”, as this final deal shifted from requiring countries to “phase out” coal to “phase down”, a change that has disappointed some. Many now look to the meeting next year that may see further pledges to cut emissions to reach the 1.5°C goal, as an analysis showed that the world is on track for a 2.4°C rise, despite these new pledges.

Fast becoming one of our most popular trail cameras, the Recon Force Elite HP4 delivers outstanding quality video, super-fast responses and some great new features, all for excellent value.
The model joined the ever-growing suite of highly regarded trail cameras offered by Browning at the start of 2021. What sets the Recon Force HP4 apart is that, while introducing some useful new settings and providing generously rich image and video resolution, it doesn’t stretch the budget too much, the way some of the higher-end trail cameras currently do.
With the HP4, Browning has successfully found a way to keep the cost of a top specification camera reasonable without compromising on any of the quality they are renowned for. After some time experimenting with this camera, we feel sure that it is set to become one of our most desirable models, fulfilling every need you would have for a trail camera.
As is the case for most of the high-spec Browning trail cameras, the HP4 includes a front-facing colour screen, but at a bumper 5cm in size, this screen really is ideal for reviewing footage while in the field, particularly if you are capturing smaller wildlife. It also can’t be stressed enough just what a great aid this large screen is when setting the camera up, as it is so much easier to check that the camera’s positioning, angle and height are all set as desired before deployment.
Despite increasing the screen size, Browning has still managed to reduce the overall size of the camera itself, which is handy when it comes to transportation, discreetness and ease of attachment to trees. The back of the camera features a sturdy metal bracket for threading a strap or cable lock through, as well as the usual tripod screw on the underside, giving you plenty of options for mounting the camera.
Some of the more notable features of the HP4 include its smart IR video, which continues capturing video as long as an animal continues to be active in view of the camera, with recordings lasting up to a maximum of 2 minutes in daylight and 20 seconds at night. Its SD card management function is another useful addition, providing the option to overwrite older images on the card if the memory gets full.
Using its top-quality specifications, the Recon Force HP4 reliably and beautifully documents the wildlife you wouldn’t normally see and is both versatile and affordable enough that it should be suitable for most circumstances.
How we tested
For an insight into the camera’s performance and its suitability for different circumstances, we used the camera in a variety of habitats where the behaviour of different wildlife could test the camera’s range of functions. After setting the camera up with a full set of AA batteries and a 32GB SD, we first focused on smaller mammals by using the camera in a low canopy broadleaved woodland setting. We used a Python Mini Lock to secure the camera to a suitable tree and positioned the camera overlooking a small woodland clearing where a few peanuts were scattered. We left the camera out here for two days and nights under the following settings:
Mode: Trail Cam; Photo Quality: Ultra; Photo Delay: 1 Secs; Multi Shot Mode: Off; Image Data Strip: On; Motion Detection: Long Range; Trigger Speed: Fast; IR Flash Power: Long Range.
The camera was then moved to a more open garden setting, where we focused on video. We set the video length to 10 seconds, but also turned on the smart IR video function.
Motion tests were performed before leaving the camera running, which is a very convenient feature to ensure that the triggers are operating as expected before deployment. This simply works by checking that a red low glow is emitted when waving your hand in front of the camera.
We also tried out the programmable stop/start timer, which informs the camera to only trigger during specified timeframes. This is another very useful feature, especially if, for example, you are targeting only nocturnal or diurnal wildlife or baiting a site and wanting to avoid excess triggers from unintended species that may be attracted to a bait during the day/night.
What we found
Under these settings, the camera captured significant activity from brown rats at night and grey squirrels during the day. In terms of still images, which are captured at 22MP, we felt that the quality, colour contrast and detail recorded is fantastic and the black and white IR images were not too grainy.
It was interesting to see that with the 1-second photo delay, whole sequences of squirrels finding and then burying peanuts in front of the camera were nicely captured, just like a broken-down video, showing the camera wasn’t missing any action in front of it.
Even when a fast-moving squirrel was leaping in and out of frame, most of the images captured were sharp, showing the value of the impressive fastest trigger speed setting of 0.2 seconds (s). It is worth noting, however, that this fast trigger speed did result in many captures of animals just as they were entering the field of view, rather than more in the centre.
In response to this, we adjusted the trigger speed to the slower 0.7s to see how this affected the captures going forward. This resulted in some captures of rats further into the centre of the image. Also, when a slow-moving domestic cat approached the area, the first capture was made once the cat had made its way into a fairly central point of the frame, resulting in a more useful image. This demonstrates the value in having an adjustable trigger speed, which allows the user to customise the set-up to the particular circumstances or the habits of target wildlife.
The Recon Force HP4 boasts a great infrared sensor with a detection range of 34 meters and utilises new long-range LEDs, so it was very encouraging to see the camera triggering when a rat was passed by at approximately 5 meters away, outside the main detection zone and partially obscured by leaf litter. Although we have not yet had a chance to put the full detection distance to test, we already feel from these captures that the detection and trigger speeds can be relied upon.
It is worth noting though that for small mammals and birds, they can often be a challenge to identify unless they are triggered very close to the camera and within the core detection zone.
When testing in the garden setting, we hoped to capture foxes but instead recorded several domestic cats alongside garden birds. Here we decided to also test the smart IR video which worked well and resulted in 20-second night videos of cats sniffing around while they remained in view.
This setting proved particularly helpful when the camera was later returned to the woodland and was triggered by a passing badger. The recording did not end until the badger had fully left the frame. Using this function therefore greatly reduces the risk of interesting behaviour being missed just because a video has been timed out by default.
After reviewing the video footage, we were first struck by just how sharp and smooth the quality was at 1920 x 1080 taken at 60 frames per second, revealing plenty of detail both during the day and at night. The level of detail produces attractive footage that could perhaps help with the identification of individual animals.
It was also a pleasing result that we found no false triggers under both the long and normal detection range and the fast and normal trigger speeds, even under some windy conditions.
Our opinion
We would have no hesitations in recommending the Recon Force HP4 for both serious naturalists, researchers and even a first-time user looking to capture reliable and quality footage in their garden or local area.
Certainly, one of the most practical features is the large 5cm colour screen which really does make a difference to set up, alongside the no-nonsense menu navigation and instruction manual. Even those that are not so technically minded should have little problem using and enjoying this camera. Large front-facing screens are by no means unique to this model, but most others are usually significantly higher priced.
The super fast picture trigger and recovery speed of 0.01s and 0.6s respectively and video trigger and recovery speed of 0.38s and 0.7s, shouldn’t fail to capture anything, but the trigger speed is adjustable which is great for flexibility. Depending on the circumstances of your detection zone and what wildlife you are targeting, switching to the slower trigger speed could be more convenient, for instance for recording slow-moving large mammals, so this function covers you for all options.
One aspect to consider is that it lacks a hybrid mode that would enable both video and still images to be captured simultaneously, which can be useful in many circumstances. It is also worth being aware that the HP4 is a red ‘low glow’ camera, and the discreet red light emitted during night-time triggers did appear to draw occasional minor attention from some wildlife on occasions. But as is often reported, most wildlife is not spooked or adversely affected by this, so the most important reason to opt for a No Glow camera instead would be if using the camera in public areas.
The field of view is 40.2°, just slightly narrower than that of a similar model, the Browning Strike Force HD Pro X. Based on our findings however, it is hard to see that this minor difference will have any significant impact on your success rates.
We found that the images and videos captured during the depths of night were particularly impressive and significantly less grainy than many older models. The sharpness and colour contrast is very aesthetic and allows for details such as fur texture to be visible on even the smaller animals.
Other highlights we found included the relatively wide range on the adjustable trigger speed, and the smart IR video which made the most of the behaviour being captured.
To conclude the HP4 is an outstanding trail camera that builds on Browning’s long-standing reputation for durable, easy-to-use and high-performance trail cameras. Even if you are considering a more entry-level trail camera, after seeing the quality of videos this camera produces it would be hard to resist not treating yourself to this camera as an upgrade, given its price.
