Flora and vegetation
332 species of vascular plants, 92 species of bryophytes and 16 species of fungi, lichens and fungus-like organisms are observed in the territory of Koryaksky reserve. The vegetation of the territory under study is comparatively poor in species. It is determined by the isolation of the region during the postglacial time. Species that have managed to survive since the pre-glacial period predominate among tree species.
The flora and vegetation of the reserve are typical for the region in general. The northern part of Kamchatka krai in which Koryaksky reserve is located is included in the tundra zone with an intermediate belt of shrubs and forest-tundras which grow near barren lands. The belt of high standing forests is represented here only by fragmental stone birch forests and band bottomland forests.
According to the character of vegetation cover the upper parts of mountain ridge slopes in the “Cape Govena” and “Lavrova Bay” areas are included in the Beringian forest-tundra geobotanical zone. The vegetation cover of the “Parapolsky Dale” area is also typical for Beringian forest-tundra. In the mountains one can observe a clearly expressed vertical zonality of vegetation: sedge-cotton-grass tundras and forests along river valleys in the forest belt; sub-Alpine belt of creeping shrubs; Alpine belt – high mountain tundras, alpine meadows, nival vegetation of the goltsi altitudinal belt (barrens). On the whole, forest tundra prevails in the vegetation cover among the zonal vegetation kinds, and among the azonal kinds – swamps and meadows of different types.
