This is a list of extinct animals of the British Isles, including extirpated species. Only a small number of the listed species are globally extinct (most famously the Irish elk, great auk and woolly mammoth). Most of the remainder survive to some extent outside the islands. The list includes introduced species only in cases where they were able to form self-sustaining colonies for a time. Only Pleistocene species, and specifically those extinct since the Ipswichian/Eemian interglacial (c. 130,000 – c. 115,000 before present (BP)), Devensian glaciation (c. 115,000 – c. 11,700 BP) or into the Holocene (c. 11,700 BP – present), are included (that is, the assemblage that can be approximately considered the 'modern' fauna which displays insular differences from the mainland European fauna). The date beside each species is the last date when a specimen was observed in the wild or, where this is not known, the approximate date of extinction.
For most of its history, the British Isles were part of the main continent of Eurasia, linked by the region now known as Doggerland. Throughout the Pleistocene (Ice age) the climate alternated between cold glacial periods, including times when the climate was too cold to support much fauna, and temperate interglacials when a much larger fauna was present. Insularity first occurred around 125,000 BP, during the Ipswichian interglacial, [1] when a warming climate raised sea levels and flooded Doggerland. This temperate climate supported an assemblage of species characterised by straight-tusked elephant (Palaeodoxodon antiquus). Around 115,000 BP the climate began to cool again as the Devensian glaciation began. The temperate species began to go extinct locally (many survived in southern refugia elsewhere in Europe). With the cooling climate, the sea level fell and by 60,000 BP a land bridge reformed so new or returning species could repopulate Britain. The colder climate supported a biome favoured by woolly mammoths (Mammuthus primigenius). [2] By around 20,000 BP the climate was so cold, with much of Britain under ice and the rest a polar desert, that little life could survive, and the glacial fauna also went extinct. The climate began to warm again around 11,700 BP, entering the present climatic period known as the Holocene. Animals repopulated Britain and Ireland. Many of the former species had gone extinct during the interval, but the majority of the surviving European temperate fauna, and some new immigrants, including modern humans (Homo sapiens), were able to reach Britain until the rising sea level once again isolated the islands. Great Britain was cut off from mainland Europe in around 8,200 BP by the Storegga Slide tsunami flooding Doggerland. [3]
Extinctions in Britain over the period have thus had three main causes:
It is important to remember that absence of evidence is not evidence of absence; the fossil record is always incomplete; [4] and many of the early dates are very approximate, since caves in Britain were often excavated before modern archaeological stratifications and dating techniques. [5] [6]
† – A species that is globally extinct
* – A species that is known to have been introduced by humans and was never present by natural immigration.
Some animals have gone extinct several times and then recolonized. The date given is of the most recent extinction. Species that have been introduced or reintroduced by humans are noted.

The white-tailed eagle has been successfully re-established on the western coast of Scotland. [69] Having clung on in parts of Wales, [70] red kites have been successfully re-established in parts of England and Scotland. [71] Ongoing projects involve both these species: the corn crake into parts of England and Scotland, and the great bustard on Salisbury Plain.
European beavers have been reintroduced to parts of Scotland, and there are plans to bring them back to other parts of Britain. A five-year trial reintroduction at Knapdale in Argyll started in 2009 and concluded in 2014. [72] A few hundred beavers live wild in the Tay river basin, as a result of escapes from a wildlife park. [73] A similar reintroduction trial is being undertaken on the river otter in Devon, England. [74] Also, around the country, beavers have been introduced into fenced reserves for many reasons including flood prevention. [75] In 2016, beavers were recognised as a British native species, and will be protected under law. [76]
In 2008, Eurasian elk were released into a fenced reserve on the Alladale Estate in the Highlands of Scotland. Reindeer were re-established in 1952; approximately 150–170 reindeer live around the Cairngorms region in Scotland.
Set up by the Wildwood Trust, Konik horses have been established across many reserves as a proxy for the extinct tarpan. [77]
In 1998, MAFF, now known as DEFRA released a report concerning the presence of two populations of wild boar living freely in the UK. [78] These boar are thought to have escaped from wildlife parks, zoos and from farms where they are farmed for their meat, and gone on to establish breeding populations. [79] [80]
Around 20 white storks pass through the UK each year. [81] A colony at the Knepp Wildland in West Sussex, aided by zoologist Roisin Campbell-Palmer, hopes to reinforce these off-path migrants by introducing adults into a fenced reserve, where the juveniles born will be able to establish other colonies further afield. [82]
The northern clade of the pool frog was reintroduced from Swedish stock in 2005, to a single site in Norfolk, England, following detailed research to prove that it had been native before its extinction around 1993.
Smaller species, mainly reptiles, such as the green lizard and Aesculapian snake, have formed colonies probably due to a result of release from captivity. [83] There have also been calls for the return of the European tree frog to the wild. [84]
Established in 2020, Celtic Reptile & Amphibian, aims to reintroduce the lost species of reptile and amphibian that once inhabited Britain, back to rewilding projects. [85] These include the moor frog, European tree frog, agile frog and European pond turtle. [86] They have already had significant success breeding the moor frog in captivity. [87] [88] The organisation also wants to see European pond turtles re-established within wetland restoration projects. [89]
The large blue butterfly has been successfully re-established from Swedish stock at several sites, but very few of these are open-access. There are also several successful cases of the establishment of new populations of heath fritillary.
There have been calls for the reintroduction of the Eurasian lynx, brown bear and grey wolf to the UK, because no large predators are living in viable populations in Great Britain. It is theorized that a large predators presence could create a trophic cascade, [90] thus improving the ecosystem. [91]
Three female bison were introduced to the West Blean and Thornden Woods in Kent, England on 18 July 2022. [92] A calf, also female, was unexpectedly born in September 2022 [93] and in December 2022 a bull was introduced. These five bison are first "complete" wild herd in the UK in thousands of years. [94] As of October 2024, the herd consists of three females, a bull and four calves. [95]
The European bison or the European wood bison, also known as the wisent, the zubr, or sometimes colloquially as the European buffalo, is a European species of bison. It is one of two extant species of bison, alongside the American bison. The European bison is the heaviest wild land animal in Europe, and individuals in the past may have been even larger than their modern-day descendants. During late antiquity and the Middle Ages, bison became extinct in much of Europe and Asia, surviving into the 20th century only in northern-central Europe and the northern Caucasus Mountains. During the early years of the 20th century, bison were hunted to extinction in the wild.
Species reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival. The goal of species reintroduction is to establish a healthy, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population. Species that may be eligible for reintroduction are typically threatened or endangered in the wild. However, reintroduction of a species can also be for pest control; for example, wolves being reintroduced to a wild area to curb an overpopulation of deer. Because reintroduction may involve returning native species to localities where they had been extirpated, some prefer the term "reestablishment".
The Eurasian beaver or European beaver is a species of beaver widespread across Eurasia, with a rapidly increasing population of at least 1.5 million in 2020. The Eurasian beaver was hunted to near-extinction for both its fur and castoreum, with only about 1,200 beavers in eight relict populations from France to Mongolia in the early 20th century. It has since been reintroduced into much of its former range and now lives from Western, Southern, Central and Eastern Europe, Scandinavia, Russia through China and Mongolia, with about half the population in Russia. It is listed as least concern on the IUCN Red List.
Local extinction, also extirpation, is the termination of a species in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions.
The island of Great Britain, along with the rest of the archipelago known as the British Isles, has a largely temperate climate. It contains a relatively small fraction of the world's wildlife. The biota was severely diminished in the last ice age, and shortly thereafter was separated from the continent by the English Channel's formation. Since then, humans have hunted the most dangerous forms to extinction, though domesticated forms such as the dog and the pig remain. The wild boar has subsequently been reintroduced as a meat animal.
Wildwood Trust is a woodland discovery park in Herne, near Canterbury in Kent, England. It features over fifty species of native British animals such as deer, badgers, wild boar, wolves and brown bear. It is located on the main road A291 between Herne Bay and Canterbury.
The wildlife of Israel includes the flora and fauna of Israel, which is extremely diverse due to the country's location between the temperate and the tropical zones, bordering the Mediterranean Sea in the west and the desert in the east. Species such as the Syrian brown bear and the Arabian ostrich have become extinct in Israel because of their loss of habitat. As of May 2007, 190 nature reserves have been established in Israel.
Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. It is an extension of the conservation practice of rewilding, which aims to restore functioning, self-sustaining ecosystems through practices that may include species reintroductions.
Translocation is the human action of moving an organism from one area and releasing it in another. In terms of wildlife conservation, its objective is to improve the conservation status of the translocated organism or to restore the function and processes of the ecosystem the organism is entering.
The fauna of Ireland comprises all the animal species inhabiting the island of Ireland and its surrounding waters.
Rewilding is a form of ecological restoration aimed at increasing biodiversity and restoring natural processes. It differs from other forms of ecological restoration in that rewilding aspires to reduce human influence on ecosystems. It is also distinct from other forms of restoration in that, while it places emphasis on recovering geographically specific sets of ecological interactions and functions that would have maintained ecosystems prior to human influence, rewilding is open to novel or emerging ecosystems which encompass new species and new interactions.
De-extinction is the process of generating an organism that either resembles or is an extinct species. There are several ways to carry out the process of de-extinction. Cloning is the most widely proposed method, although genome editing and selective breeding have also been considered. Similar techniques have been applied to certain endangered species, in hopes to boost their genetic diversity. The only method of the three that would provide an animal with the same genetic identity is cloning. There are benefits and drawbacks to the process of de-extinction ranging from technological advancements to ethical issues.
Rewilding Europe is a non-profit organization based in Nijmegen, the Netherlands, dedicated to creating rewilded landscapes throughout Europe. The group's efforts have contributed to increasing the stock of previously endangered species such as the European bison and the Iberian lynx.
Feral: Searching for Enchantment on the Frontiers of Rewilding is a 2013 book by the British activist George Monbiot. In it, Monbiot discusses rewilding, particularly in the United Kingdom. It was first published by Allen Lane, a hardback imprint of the Penguin Group. The book received positive critical reviews, and won several awards. It inspired the founding of Rewilding Britain.
The Eurasian beaver has been the successful subject of a century of official and unapproved species reintroduction programs in Europe and Asia. Beavers had been driven to the point of near extinction in Eurasia by humans trapping and hunting them for their meat, fur and castoreum. The reintroductions and conservation led in 2008, to the IUCN assessing the Eurasian beaver as being of "least concern" on its red list.
The Eurasian lynx is the target of ongoing species reintroduction proposals in Great Britain. Proposed locations include the Scottish Highlands and Kielder Forest in Northumberland, England.
The wood-pasture hypothesis is a scientific hypothesis positing that open and semi-open pastures and wood-pastures formed the predominant type of landscape in post-glacial temperate Europe, rather than the common belief of primeval forests. The hypothesis proposes that such a landscape would be formed and maintained by large wild herbivores. Although others, including landscape ecologist Oliver Rackham, had previously expressed similar ideas, it was the Dutch researcher Frans Vera, who, in his 2000 book Grazing Ecology and Forest History, first developed a comprehensive framework for such ideas and formulated them into a theorem. Vera's proposals, although highly controversial, came at a time when the role grazers played in woodlands was increasingly being reconsidered, and are credited for ushering in a period of increased reassessment and interdisciplinary research in European conservation theory and practice. Although Vera largely focused his research on the European situation, his findings could also be applied to other temperate ecological regions worldwide, especially the broadleaved ones.
Jim Crumley is a Scottish journalist, a former newspaper editor and regular columnist for the Dundee Courier and The Scots Magazine. He is also the author of more than 40 books, mostly on the wildlife and wild landscapes of Scotland, many of them making the case for species reintroductions, or ‘rewilding’. His Seasons series, a quartet of books exploring the wildlife and landscapes and how climate change is affecting our environment across the four seasons, is highly acclaimed. The Nature of Autumn was longlisted for the Wainwright Golden Beer Book Prize 2017 and shortlisted for the Richard Jefferies Society and White Horse Bookshop Literary Prize 2017. The Nature of Spring was BBC Radio 4’s Book of the Week. The Nature of Summer, published in 2020, was shortlisted for the 2021 Highland Book Prize. His most recent book, Lakeland Wild, is his first to focus entirely on an English landscape.
Celtic Rewilding, formally known as Celtic Reptile & Amphibian, is a conservation company, established in 2020, by Harvey Tweats and Tom Whitehurst, with the initial aim of reintroducing extinct reptiles and amphibians back to rewilding projects within the UK. However, the company's scope has since broadened to all lost species of the UK and northern Europe. It is based in Leek, Staffordshire.
