Some species which were present in Britain before past glaciations, often during periods with a warmer climate than now failed to return after the Last Glacial Maximum. Amongst these are Rhododendron ponticum and rabbits, now considered invasive and non-native.
A species is only deemed native if it reached the British Isles without human intervention (either intentional or unintentional). That means that to be native the species must have reached Britain before the
A few endemic species are Arctic-Alpine species, survivors of Arctic species of plants and animals which either adapted to the warming climate or became isolated in suitable areas of mountains or lakes which still retained a suitable micro-climate. A common misconception is that the entirety of the British Isles was under glaciers and was uninhabitable both for humans, plants and animals. Whilst unsuitable for most species, a number of Arctic species survived in the areas not under glaciers in southern areas of England, Wales and south west Ireland and were either driven to extinction in the British Isles or to micro-climatic refuges as the climate warmed and the Arctic conditions retreated north.
Most endemic species or subspecies however date to more recent, post-glacial times, many having spread via land bridges or along the Atlantic seaboard of Europe.
Origins of endemic species
- Ice Age survivors in suitable micro-climates
- Subspecies (offshoots) of a larger species, many may in turn develop into new species
- Glacial or pre-glacial survivors which have become extinct across much of their former range or have never occurred outside of Britain.

Spiders
Amphipoda (freshwater)
- Microniphargus leruthi – found across Ireland, Wales and Southern England. Comprises three 'cryptic species'.

Insects

Isopods
Birds
Britain has few endemic species of birds but quite a few
- willow grouse– doesn't change plumage in winter as willow grouse does – Upland and Moorland areas of Great Britain and Ireland.
- pied / white wagtail–throughout British Isles.
- Shetland Islands, Scotlandonly.
- Fair Isle wren – Fair Isle, Scotland only.
- St Kilda wren – St Kilda Islands, Scotland only.
- Scottish crossbill – Highlands, Scotland only.
- British Isles subspecies of white-throated dipper
Mammals
Britain has a few subspecies of mammals but no endemic species. Many again are Ice Age survivors that adapted to the new conditions; others arrived in warmer conditions whilst the land bridge still existed.
- Irish hare or the Irish subspecies of the mountain hare– Mountain hares are also found in other locations of the British Isles, but in Ireland have the distinction of not turning white in winter.
- Scottish red deer
- Scottish wildcat – Formerly also found in Northern England and Wales, this subspecies of the European wildcat is now restricted to a few locations in Scotland largely due to hunting and hybridisation with domestic cats.
- St Kilda field mouse – St Kilda Islands only. A subspecies of the wood mouse.
- Orkney vole – Orkney only. A subspecies of the common vole.
- Skomer Island only. A subspecies of the bank vole.
- Canna mouse - Canna, Scotland only. A subspecies of the house mouse.
Aquatic fauna
Cnidaria

- Ivell's sea anemone (Edwardsia ivelli) described in 1975 and found in Widewater Lagoon in West Sussex.
Fish
In some areas of uplands in the British Isles the retreating glaciers left melt water in hollows which had been carved out by the movement of ice. In these, Arctic species of fish survived, due often to the sheer depth of the lakes and the colder temperatures. For the young endemic fish varieties of the British Isles, it is usually controversial whether they should be considered as distinct taxa (species or subspecies) or just as isolated populations of their ancestral species.
As global warming affects the British climate there is some concern for these species, some confined to a handful of lakes. Action has been taken to protect them, as is the case with vendace which has been moved to tarns in nearby mountains due to the cooler temperatures. It is hoped that these will act as refuges should the species die-out in the lower-level lakes where they occur naturally.

Distribution
The distribution of endemic species seems to have a north western bias and with endemic species on the whole showing an oceanic / alpine distribution with most endemics being found in upland areas or islands.
Endemic livestock breeds
Human bred-animals are not usually classified as distinct subspecies but rather breeds which is a similar concept. However some animals such as
