List Of Non-endemic Ant Species Introduced To Great Britain
This is a list of ants of Great Britain, including endemic and introduced species. Compared with much of the rest of Europe, Great Britain has a smaller number of ants. The size and diversity of ant species in any area is largely determined by the highest summer soil temperature, and this being so, it is not surprising that the greatest concentration of different species is centred in the warmer parts of the country – Dorset, Hampshire, Surrey, the Isle of Wight and Kent being the 5 richest counties, with 33, 31, 29, 27 and 26 different species present respectively. A few species, best exemplified by ''Lasius niger'' and ''Myrmica rubra'', are truly Cosmopolitan distribution, cosmopolitan, colonising a great variety of different habitats (often including those directly resultant from human activities). These species are very common in most places, and have ranges that cover most of the nation. The larger part of Great Britain's ant species are, however, considerably more special ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ...
