Palearctic

The Palearctic is one of the eight ecozones dividing the Earth surface (see map).

It includes the terrestrial ecoregions of Europe, Asia north of the Himalayas, Africa north of the Sahara Desert and some parts of the Middle East.

Physically, it is the largest ecozone, but it has few unique features since it is central and temperate or tundra, with no truly tropical areas, but some arid areas with near-tropical climates (Sicily, southern Spain, Greece).

Because of its size, it is often divided for convenience into the Western Palaearctic and the Eastern Palaearctic, the Ural mountains being taken as the boundary.

This zone and the Nearctic were often connected by the Bering land bridge, and therefore have more similarities than other faunal zones. They are therefore sometimes considered together as a circumpolar Holarctic zone.

Ecologically important features:

One bird family, Prunellidae, the accentors, is endemic to the Palearctic region. The Holarctic has four other endemic groups: Gaviidae, divers, Tetraoninae grouse, Alcidae auks, and Bombycillidae waxwings.

Animal families originally unique to the Palearctic ecozone include:
