To forestall a mass extinction, fight forest fragmention Updated for 2026
Much of the Earth was once cloaked in vast forests, from the subarctic snowforests to the Amazon and Congo basins.
As humankind colonised the far corners of our planet, we cleared large areas to harvest wood, make way for farmland, and build towns and cities.
The loss of forest has wrought dramatic consequences for biodiversity and is the primary driver of the global extinction crisis. I work in Borneo where huge expanses of tropical forest are cleared to make way for palm oil plantations.
The biological cost is the replacement of some 150 forest bird species with a few tens of farmland species. But forest is also frequently retained inside or at the edges of oil palm plantations, and this is a pattern that is replicated globally.
The problem, according to new research published in Science Advances, is that the vast majority of remaining forests are fragmented.
In other words, remaining forests are increasingly isolated from other forests by a sea of transformed lands, and they are found in ever-smaller sized patches. The shockwaves of loss thus extend far beyond the footprint of deforestation.
Accessible forests
The team, led by Nick Haddad from North Carolina State University, used the world’s first high-resolution satellite map of tree cover to measure how isolated remaining forests are from a non-forest edge. Edges are created by a plethora of deforesting activities, from roads to cattle pastures and oil wells, as well as by rivers.
They found that more than 70% of remaining forest is within just 1km (about 0.6 miles) of an edge, while a 100 metre stroll from an edge would enable you to reach 20% of global forests.
Comparing across regions, the patterns they find are even starker. In Europe and the US, the vast majority of forest is within 1km of an edge – some of the most ‘remote’ areas in these regions are a stones throw from human activity. ‘Getting away from it all’ has never been more challenging.
If you want remote forests on a large scale you’ll have to head to the Amazon, the Congo, or to a lesser degree, central and far eastern Russia, central Borneo and Papua New Guinea.
Biodiversity reduced
These findings wouldn’t be cause for alarm if wildlife, forests, and the services that they provide humankind such as carbon storage and water, were unaffected by fragmentation.
However, by drawing together scientific evidence from seven long-term fragmentation experiments, Haddad and colleagues show that fragmentation reduces biodiversity by up to 75%. This exacerbates the extinction risk of millions of forest species, many of which we still don’t know much about.
Forest species struggle to survive at edges because these places are brighter, windier, and hotter than forest interiors. Edges become choked by rampant vines and invaded by disturbance-tolerant, parasitic or invasive species that outcompete the denizens of dark forest interiors.
In Borneo, for example, small forest patches house bird communities that are far more similar to those found in the surrounding oil palm than to those of larger forest tracts.
The survival of large, carbon-rich trees – the building blocks of any intact forest ecosystem – is reduced in smaller and more isolated forest fragments. These patches thus fail to maintain viable populations, which over time are doomed – an ‘extinction debt’ yet to be paid.
With so much global forest in close proximity to humans, larger forest animals such as chimpanzees, gorillas, tapirs or curassow birds are being hunted to extinction in individual areas. This shifts animal communities within the forest fragments to one dominated by small-bodied species.
Further, hunters are willing to penetrate forests for several kilometres from edges in search of game, effectively making the truly wild global forest estate yet smaller.
Difficult management decisions
The insidious effects of fragmentation mean that the top conservation priority must be preventing further incursions into dwindling wildernesses. By preventing the first cut we can help to prevent global fragmentation and the further loss of biodiversity.
Of course, we should not ignore fragmented regions. Some of these, including the Brazilian Atlantic forest, Tropical Andes and Himalayas, share a toxic mix of hyperdiversity, endemic species with tiny ranges, and severe fragmentation.
The critically-endangered Munchique wood-wren, for instance, exists only in a handful of peaks in the Colombian Andes, but these are now isolated from each other by cattle pastures and roads. Here we must seek to restore forest cover and improve connectivity between larger fragments if we are to prevent extinctions.
However, the rapid expansion of human populations, greed, and meat consumption mean that more forest is likely to be lost, even if farm yield and efficiency can be improved to help bridge gaps between current and future demand.
The difficult question is where should this expansion happen? Given the severe degradation of small and isolated fragments, perhaps conversion could target some of these patches, coupled with wilderness protection and expansion.
Next time I visit my local National Park – the highly fragmented Peak District – I will spare a thought for the species that are being harmed by their habitats being broken up into ever smaller chunks.
There are no easy answers to the problems of fragmentation, but our forests urgently need a global management plan.

Swedish wildlife extinction threat as loggers clear-cut ‘old growth’ forests Updated for 2026
A camera follows a peregrine falcon as it swoops low over an attractive, pristine river hugged by trees in remote northern Sweden.
It then soars higher, revealing that the river flows through a large area which has been clear-felled of forest.
Stripped bare, it is as if an atomic bomb has been detonated over the land.
Aimed at raising public awareness, the message of the video by the Swedish Society for Nature Conservation (SSNC) (see below) is clear: Sweden no longer looks like what you think.
While Sweden’s forest cover of 60% of the country’s land area is one of the highest in Europe, it is calculated that more than half of Sweden’s productive forests have been felled since the 1950s.
With paper, pulp, cardboard, and sawn timber comprising the main products of the forestry sector, much of it bound for European markets, the vast majority of the country’s forest landscape has been affected by intense forestry methods.
Dominated by five large companies (the largest of which, state-owned Sveaskog, owns 14% of the country’s forest) and a number of smaller landowners, the forestry sector has the rights to 96% of Sweden’s productive forests – land deemed as suitable for forestry.
Logging vs. old growth and biodiversity
With much of Sweden’s forest cover comprised of young forests not yet ready to be harvested, there is intense pressure to log Sweden’s remaining mature, old-growth forests – ‘natural’ forests so far only minimally affected by modern forestry and typically of great importance for the ecosystem and biodiversity.
Sweden no longer looks as you think – from SSNC / Naturskyddsföreningen on Vimeo.
I sit down with a worried Malin Sahlin, the SSNC’s boreal forest policy officer, in her office in Stockholm. “The country is going into the last stage of transformation in terms of forest ecology right now due to the fact we are clear-felling the last of our forests that have never been clear felled before … and turning the forest landscape, through replanting, pretty much into a monoculture”, she tells me.
The future for Sweden’s forests looks bleak. According to Sahlin, “if we continue today business as usual, there might in 20 years from now only be 5% of natural-like forests left and the rest could be in production.”
Sweden’s forest cover comprises part of the vast boreal forest that stretches across the northern part of the globe. Its old-growth forests are an important carbon sink that helps to regulate the earth’s temperature.
Not only this, but such forests typically contain a large amount of dead wood, which forms a crucial habitat for many species. A report by the WWF cites the severe lack of dead wood as constituting one of the main reasons for the loss of biodiversity in European forests.
Of over 20,000 species of flora and fauna assessed in Sweden according to IUCN criteria, around 20% are categorized as ‘red-listed’ (nearly half of which are threatened), with mature forests being especially important for many of those species.
Published every five years, the Swedish Species Information Centre in Uppsala is currently updating Sweden’s Red List, which is due to be issued in 2015. While pointing out that extinction processes in forest ecosystems are long term, Artur Larrson of the Centre argues that the current situation is “bad with a constant decline in species.”
Larsson further explains: “Typically more sedentary species like species like fungi, bryophytes and lichens are harmed most … but even more mobile species like birds, mammals and flying insects can also suffer from the extensive landscape change that forestry causes, for example a lack of dead wood of the right quality, lack of old and slow growing trees, denser and darker forests, and so on.”
Failures of regulation, protection and certification
In 1999 Sweden outlined 16 environmental objectives to be met by 2020 – one of which is sustainable forests. However, the Swedish Environmental Protection Agency – the body tasked with monitoring the objectives – has deemed the objective as unreachable under current policy instruments.
With the forestry model based on the principle of ‘freedom with responsibility’, critics argue that the lack of clear and stringent legislation has led to this freedom being hijacked by irresponsible forestry practices.
As a report by the SSNC argues, “the Swedish forestry model involves clear-cutting as the default method, soil scarification, systematic use of chemicals, plantation forestry and the use of non-native species.”
Failure is also laid at the door of the certification schemes of the Forest Stewardship Council and Programme for the Endorsement of Forest Certification tasked with monitoring that forestry is conducted sustainably according to the criteria.
“We’ve been out in the field over many years and we have found that the big five forest companies are not following the criteria of the certification”, says Malin Sahlin. “Furthermore, the certification bodies have not done their job properly in many of the cases of violations that we have reported.”
The wider issue is also that there is not enough protected forest in Sweden. With only 4% of its productive forest under formal protection, Sweden lags far behind the recommendations of conservationists who argue that at least 20% of the country’s productive forest land should be protected.
Furthermore, it is also clear that Sweden is not meeting the biodiversity objectives of the Convention on Biological Diversity, which stipulates that at least 17% of the land surface area should be conserved by 2020. Artur Larsson points out that it is not only a question of protecting what remains, but also restoring already ‘degraded’ forest if biodiversity targets are to be met.
Jobs, profits, and biofuels
The powerful Swedish forest industry and its allies – former Swedish Prime Minister Göran Persson has been a chairperson of Sveaskog since 2008 – have branded the assessments of critics as “alarmist” and point to the importance of the industry for Sweden’s economy.
According to the Swedish Forest Agency, exports of forestry and forest industry amounted to SEK 118 billion (over £10 billion) in 2013, contributing to 11% of the country’s total export value. In terms of jobs, it is estimated that around 60,000 people directly depend on the industry whilst employing triple that number indirectly.
The industry is also keen to burnish its image in terms of the growing role of wood fuels as a renewable energy source. In fact, having eclipsed oil, bioenergy now accounts for one-third of Sweden’s domestic energy use, with wood fuel accounting for nearly half of biomass sources.
Critics counter that while commercial forestry is indeed an important generator of jobs and revenue, it is only one consideration among many. Maintaining biodiversity, clean air and water, as well as eco-tourism – a boom industry in Sweden – all depend on healthy forests.
Looking to the future
In just two decades from now, Sweden faces the prospect of having lost much of its remaining old-growth forests with the rest (outside of protected areas) turned more or less into plantation forests lower in biodiversity, their original character and value having been degraded.
Many people agree that, in addition to the adoption of better practices and more effective regulation including formal protection, there needs to be an immediate stop or at least scaling back of the cutting down of natural-like forests to halt the current trend. Yet such a decision would be unpopular as it would cut into the profits and jobs of the big forestry companies.
With Sweden’s forests at a critical juncture, it remains to be seen whether Sweden’s new government, with the Green Party occupying key posts, will muster up the necessary political will to take the necessary steps.

Happy New Year! To put the cap on 2014, we’ve highlighted some of our favorite biodiversity research and stories from the year. We’d love to hear what rocked your 2014 – pass us the link in the comments section!
- Reconciling Diversification: Random Pulse Models of Speciation and Extinction
- Predicting rates of interspecific interaction from phylogenetic trees
- Tale of two phylogenies: comparative analyses of ecological interactions.
Hundreds of new species have been described this year all over the world. Here are some of my favorites:
- A fossilized skull of one of the largest mammals that walked along with the dinosaurs in the Late Cretaceous, was discovered in Madasgcar. The species named Vintana sertichi was a 9kg gondwanatherian herbivore, that reminds me of a coypu. Up to now, the only information we had about gondwanatherian mammals came from teeth and small pieces of jawbones;
- A new species of annual fish from southern Brazil, Austrolebias bagual (bagual is a term from the Pampas that means untamed, unbroken horse or unsocial);
- The mushroom looking animals, form the deep oceans of Australia, Dendrogramma.
- A montane forest dwelling Tapaculo, form northeastern Brazil.
- And the coolest one; a new species of tree frog from the Amazon has been named after the Prince of Darkness, Ozzy Osbourne.
At last, a couple of species have been declared extinct in 2014 (for more information see the timeline of extinctions):
- Acalypha wilderi, a small shrub that inhabited the Cook Islands.The species has not been seen since 1929, and it seems that it disappeared due to habitat modification;
- Stipax triangulifer. This is a “virtually unknown” arachnid species that was collected only once in 1894 in the Seychelles island of Mahe, and was never spotted again.

The Avian Phylogenomics Project, an international team with more than 200 researchers worked in a collective effort to sequence the whole genome of 45 bird species, comprising the main clades of modern birds. The project published 28 papers, in journals like Science, Gigascience and Genome Biology, in just one day! One of their key papers is Jarvis et al., “Whole -genome analysis resolve early branches in the tree of life of modern birds”. Among their main findings are: 1) Two events of speciation happened around 66 mya, just after the dinosaurs went extinct, giving origin to most of the birds we know nowadays; 2) Avian genome is very reduced, with few repetitive DNA; 3) Vocal learning evolved independently, at least twice; 4) Tooth loss happened from lost enamel mutations, around 116 mya. Nonetheless, the most important steps accomplished by the group, is a better representation of the phylogenetic relationship of birds, with some very impressive changes, e.g. falcons are closer relatives to parrots than to other group of prey birds like hawks. Several other fields of biology must benefit from this better solved piece in the puzzle of the tree of life, especially fields like ecology, which in the last years has investigated the phylogenetic structure of communities as a way to understand patterns of diversity on Earth and the processes determining them. Maybe two last very important messages from Jarvis et al. (and the other of papers resulting from this project) are that: 1) basic science (e.g. taxonomy) is an essential tool for the next big steps toward understanding life on Earth; and 2) improvements on scientific knowledge are more and more related to collective efforts of huge networks of scientist and institutions around the world, working together in ambitious projects.

Forget horses, 2014 has been the year of the lichen. And although most readers are probably uninclined to overthrow thousands of years of Chinese tradition to make it so, I’m here to tell you why it’s worth the effort. Ecologists studying lichens have worked hard this year to push their traditionally esoteric research subject out into mainstream ecology. In honor of 2014’s listicle-mania, here are the top four ways that lichenologists have really broken the mold. You won’t believe what they found…
4. Lichens impact ecosystems at both micro and macroscales. From Porada et al comes a brand-new estimation of how lichens contribute to global biogeochemical cycles. Zooming in, Delgado-Baquerizo et al show that lichen species in biological soil crusts can cause fine-scale variation in the nutrients and microbes that reside under them.
3. Lichens are great for testing general ecological theory and models, both new and old. Pastore et al found no evidence for a competition-colonization tradeoff in the life-history traits of lichens inhabiting rocks over a 30+ year experiment. Time to lay this old idea to rest? From Ruete et al comes a cool new model for estimating dispersal rates in a metapopulation that is at disequilibrium from presence/absence data, patch ages, and past distributions. Because really, when aren’t we in a disequillibrial state? And yes, they tested it with lichens because epiphytes are great models of meta-structure.
2. We have discovered that lichens have traits too! Farber et al found that the performance of lichens with light-absorbing versus light-reflecting pigments recapitulated the distribution of these species along a vertical light gradient in boreal tree canopies. Lichens, however, may be more variable in their traits than plants or animals. Asplund & Wardle found that the community-level response of lichen N and P-content to a nutrient gradient occurs mainly intra-specifically, and not because of species turnover. Perhaps fungi are more flexible?
1. It’s been a great year for lichens’ better half- the algae and cyanobacteria that do all the photosynthesizing in the relationship. Although historically underappreciated by lichenologists, this year saw a barrage of papers exploring diversity of these “photobionts”, from across whole communities and large taxonomic groups (Lindgren et al, Nyati et al, Sadowska-Des et al) to genetic diversity within a single lichen individual (Dal Grande et al). It’s becoming increasingly evident that partner specificity and local adaptation among photobionts is a key determinant of whether a lichen-forming fungal species has a broad (Werth & Sork, Muggia et al) or narrow distribution (Dal Grande et al). With increasing interest in the ecology of microbial systems, the role of symbiosis in the community ecology of lichens is ripe for research. If 2014 was the year of the lichen, 2015 will be for their algae.

2014 by the numbers:
221 – the number of new species described by CalAcademy of Sciences this year. I was particularly charmed by the description of the defensive behavior of the Hero Ant of Madagascar (Malagidris sofina), which hurls itself at invaders, kamikaze-style, knocking them off the nest. See for yourself.
2,218 – Number of plants and animals currently listed as threatened or endangered by the Endangered Species Act. There is an active recovery plan for about half of those.
1 – Number of species delisted under the ESA during 2014. The Island night lizard (Xantusia riversiana), the poster child of this post, was originally listed in 1977, and has benefitted from the removal of invasive mammals from the Channel Islands, and is considered recovered.
90% – Estimated population losses for the Monarch butterfly over the past two decades. They are now being considered for ESA listing.
1.6 million – Area (km²) proposed in 2014 as additions to marine protected areas worldwide, including Fiji, Gabon, Palau, and the US.

Deconstructing Defaunation Updated for 2026

Many species globally are threatened by numerous biotic and abiotic stressors, resulting in declining population and shifts in ecosystem functioning.
Science recently released a special issue on defaunation, which spanned seven articles detailing the recent decline in animal species diversity and abundance. Among others, the issue included two peer-reviewed articles, an opinion piece, and an analysis of national policies tied to global and local conservation strategies. The statistics associated with defaunation are sobering, but the issue presents a few solutions to help us curb this global environmental crisis.
First, a damage assessment. According to Defaunation in the Anthropocene, between 11,000 and 58,000 species go extinct each year. At least 16% of all vertebrate species are endangered or threatened, and there’s been a 28% decline in their abundances since the 1970s. Approximately 40% of invertebrate species are considered threatened, though less than 1% of described invertebrates have been assessed. There is data to suggest that invertebrate species’ abundances are also decreasing, but it’s difficult to put an exact number on that decline since they are not as well monitored as vertebrates. On a global scale, these statistics may be underestimated because our monitoring practices bias our data toward specific taxa. Groups of large and charismatic organisms, like mammals and birds, get most of the attention because they are easier to monitor and more sympathetic than invertebrates, amphibians, and reptiles. In some systems this is beneficial, where large mammals and birds are the most threatened and contribute significantly greater function to an ecosystem than smaller organisms. However the opposite can be true in other instances, so it is critical that we prioritize greater sampling of underrepresented groups.
Additionally, there is concern that such measures of declines in species and abundance may not reflect the true extent of our ecological troubles. Shifts in ecosystem compositions may not be reflected in a given measurement of biodiversity, yet are nonetheless indicative of environmental change. The primary goal behind many conservation strategies has been to restore a species or population to a certain number. While population viability is critical for any species, the authors argue that ecosystem functionality is a useful yet underutilized goal for conservationists. With this goal, the composition of an ecosystem (i.e. the identity and abundance of resident species) can be more flexible, as long as the ecosystem functions in a similar way. The issue with this then becomes how to measure ecosystem function, or rather, against what do we compare it? Do we set an arbitrary time in history that we would like to restore it to, or do we attempt to maintain its function while integrated with a unique environment managed by humans? Some proponents of the latter strategy see historical comparisons as unrealistic and uninformative, especially given our changing climate. Regardless, restoring the functionality of ecosystems is a key predictor of the future success of not only animal and plant populations, but the human population as well.
One of the strongest arguments this issue makes derives from its use of specific economic values of animals and ecosystems. According to the article Wildlife decline and social conflict, the harvest of land and sea animals accounts for $400 billion annually around the world. Defaunation in the Anthropocene claims that pest control by native U.S. predators is worth approximately $4.5 billion annually, and that the decline in North American bat populations (a specific type of pest controller) has cost the agriculture industry $22 billion in lost productivity. Insect pollinators are required for about 75% of the world’s food crops, and are therefore responsible for approximately 10% of the economic value of the entire world’s food supply. According to the World Bank, food and agriculture represents about 10% of global GDP, which in 2012 was estimated at $72 trillion. If we take total food supply to be approximately $7.2 trillion (again, estimating), then insect pollinators are worth around $72 billion dollars. These estimates apply tangible figures to a broad and occasionally overwhelming issue, and may be good starting points to unite many different stakeholders under a common currency.
The article Reversing defaunation: Restoring species in a changing world details the different strategies conservationists use to preserve species abundances and their associated ecosystem functions. These strategies can broadly be grouped into two categories, translocations and introductions. Translocations involve moving individuals within their indigenous range to either reinforce a local population or to reintroduce them following a local extinction. Introductions, on the other hand, move species outside of their indigenous range to prevent a global extinction of a species or to replace a lost ecosystem function. Though planning a conservation strategy in terms of these labels can be useful for setting long-term goals, they are not mutually exclusive. Certain strategies can incorporate aspects of both translocation and introduction, or can introduce a species both to preserve its numbers and to restore ecosystem functionality. Therefore, it’s best to use these terms as guidelines for how to measure the success of any plan rather than as constraining requirements.
These losses in biodiversity, and their associated shifts in ecosystem functioning, are primarily driven by a combination of over-hunting, habitat destruction, impacts of invasive species, climate change, and disease. The Defaunation articles make a point of addressing national policies aimed at preventing species extinctions, namely those regarding over-hunting and poaching. Many of these policies simply impose penalties for illegal hunting rather than address the underlying causes of the issue, poverty and starvation. While it’s unrealistic to expect a conservation plan to alleviate world hunger and income inequality, it may be useful to consider animal overexploitation as an unintended side-effect of the economic cycle caused by scarcity. Supply and demand states that as a species becomes less common, its value on the market rises. However, this scarcity also leads to a reduction in the amount caught per unit effort. The rise in price drives a greater hunting effort by the sellers, further decreasing the population, and the cycle begins again. Since many of these hunters are using their profits to feed themselves or their families, simply enacting penalties for poaching may not have the intended effect. Overhunting is not a simple problem, and most likely will not have a simple solution. However, the only way we can begin to address it is by determining its causes.

Europe’s vultures face extinction from toxic vet drug Updated for 2026
Following recent catastrophic declines of vultures in Asia that left landscapes littered with carcasses, vultures in Europe and Africa may be set to follow, according to BirdLife International.
The warning comes following the discovery that a veterinary drug that’s lethal to vultures even at low doses is commercially available in Europe.
“Vultures play a fundamental role that no other birds do: they clean our landscapes”, said Iván Ramírez, Head of Conservation for BirdLife International in Europe and Central Asia.
And that means they are for human and animal health as they clean up the rotting remains of dead animals.
Diclofenac has already wiped out vultures in South Asia
Used to treat inflammation in livestock, diclofenac has already wiped out 99% of vultures in India, Pakistan and Nepal.
A non-steroid anti-inflammatory drug (NSAID) present in many commonly used drugs that are used for treating moderate pain, diclofenac is extremely toxic to vultures in small doses. Vultures eating cattle treated with a veterinary dose of diclofenac will die in less than 2 days.
The decline of vultures in Asia was shockingly fast – quicker than any other wild bird, including the Dodo. Within a decade species such as the White-rumped Vulture fell by 99.9% as a result of diclofenac in India alone – leaving only one bird in a thousand alive.
A safe alternative drug, meloxicam, has been identified and tested on vultures and a range of other bird species. The meloxicam patent is more than 10-years old, meaning any pharmaceutical company can produce it with no royalties or licence fees to pay.
But now diclofenac has reached Europe
But despite the dangers and the availablity of alternatives, BirdLife has found that the drug is commercially available in Spain and Italy – both stronghold countries for European vulture species.
Since 1996, the EU and national governments have invested significant resources on conserving vultures, and there have been at least 67 LIFE projects related to these species. Between 2008 and 2012, nine vulture conservation projects alone received €10.7 million.
“We know what we need to do in Europe – ban veterinary diclofenac”, said Jim Lawrence, BirdLife’s Preventing Extinctions Programme Manager. “All these European conservation efforts would be useless if the use of veterinary diclofenac becomes widespread.”
Four vulture species breed in Europe: the Endangered Egyptian Vulture, the Near Threatened Cinereous Vulture, and important populations of Griffon Vulture and Bearded Vulture.
Three of the four vulture populations have been increasing steadily (except the Egyptian Vulture), partly due to the intensive conservation efforts funded by European Union budget lines.
A host of other threats in Africa
As well as the impending threat of diclofenac, a multitude of other complex threats need to be unravelled further in Africa, and investment needed to tackle them.
African vultures are facing increasing threats from poisoning (deliberate and accidental), persecution for body parts to be used in traditional medicine, habitat loss, collision with power-lines, and more.
The birds have declined in West Africa on average by 95% in three decades. Across Africa, seven of the eleven vulture species are now listed as globally threatened, with species such as Hooded Vulture recently being up-listed to Endangered in 2011.
“Three of every four old-world vulture species are already globally threatened with extinction or Near Threatened according the IUCN Red List of Threatened Species”, said Kariuki Ndanganga, BirdLife Africa’s Species Programme Manager.
“Unless threats are identified and tackled quickly and effectively, vultures in Africa and Europe could face extinction within our lifetime.”
He is now leading an effort to raise £20,000 to identify, review, prioritize and tackle the threats to vultures across the continent.
The decline is global
Of 11 vulture species found in Africa, seven (including five of the six species endemic to Africa) are globally threatened. Five of these species joined the Red List of threatened species only in the last seven years. The Hooded Vulture – a historically widespread species – was listed as Endangered in 2011.
There are 21 species of vultures in the world, five of which can be found in the American continent. The other 16 are distributed across Africa, Europe and Asia.
Of these so-called Old World vultures, 75% are globally threatened or near-threatened, with the number of threatened species expected to rise in the next conservation status assessment.
