The property comprises seven component parts, within an 80km long corridor along the warm-temperate and extremely humid eastern coast of the Black Sea. They provide a series of the most typical Colchic ecosystems at altitudes ranging from sea level to more than 2,500 metres above it. The main ecosystems are ancient deciduous Colchic rainforests and wetlands, percolation bogs and other mire types of the distinct Colchic mire region. The extremely humid broad-leaved rainforests comprise a highly diverse flora and fauna, with very high densities of endemic and relict species, with significant numbers of globally threatened species and relict species, which survived the glacial cycles of the Tertiary. The site is home to approximately 1,100 species of vascular and non-vascular plants, including 44 threatened vascular plan species, and almost 500 species of vertebrates, and a high number of invertebrate species. The site also harbours 19 threatened animal species including sturgeon, notably the critically endangered Colchic Sturgeon. It is a key stopover for many globally threatened birds that migrate through the Batumi bottleneck.
