[3] The ecoregion extends along the thin coastal strip from the southeastern corner of Bulgaria in the west, across the northern coast of Turkey, to Georgia in the east, where it wraps around the eastern end of the Black Sea.

[1] The Colchic or Colchian forests are found around the southeast corner of the Black Sea in Turkey and Georgia in and around the Machakhela National Park.

[4] The Colchic region has high rainfall, averaging 1,500–2,500 millimetres (59–98 inches) annually,[5] with a maximum in excess of 4000 mm, and is home to some of Europe's temperate rainforests.

[8] Water birds found in the ecoregion include the eastern imperial eagle (Aquila heliaca), Dalmatian pelican (Pelecanus crispus), great white pelican (Pelecanus onocrotalus), pygmy cormorant (Microcarbo pygmaeus), white-headed duck (Oxyura leucocephala), ferruginous duck (Aythya nyroca), red-crested pochard (Netta rufina), black stork (Ciconia nigra), white stork (C. ciconia), common crane (Grus grus), demoiselle crane (Grus virgo), greater flamingo (Phoenicopterus roseus), and Bewick's swan (Cygnus bewickii).

[1] Much woodland has been converted to arable land to grow crops such as hazelnut, tea, citrus fruit, and bamboo.
