Kamchatka-Kurile meadows and sparse forests


The Kamchatka-Kurile meadows and sparse forests ecoregion covers the coastal zones of the Kamchatka peninsula, northern section of the Kuril Islands, and the Commander Islands in the Russian Far East. The region noted for its sparse forests of Betula ermanii, and also for extensive tall-herb meadows. It is in the Palearctic realm, and mostly in the boreal forests/taiga biome with a Humid continental climate, cool summer climate. It covers.

Location and description

The coasts of Kamchatka are relatively flat, and cooled by the cold current of the Sea of Okhotsk to the west, and the East Kamchatka Current that flows down the east coast on the Bering Sea side. The ecoregion includes the Kuril Islands down to Urap Island, the northern-most 800 km of islands that stretch down from the peninsula. The Commander Islands lie in the 175 km to the east of the middle of the peninsula in the Bering Sea. The area is volcanic, and the soils are Andosol.

Climate

The climate of this region is mostly Subarctic climate, without dry season. This climate is characterized by mild or cool summers and cold, snowy winters. with oceanic influences.
There is no permafrost south of 57 degrees north, reflecting the relatively warmer conditions. Precipitation can reach 2,500 mm per year, compared with lows of 450 mm in the central valley where the mountains provide some protection.

Flora

The main floral communities are dwarf forest, sparse forests, tundra, and some meadows. Common tall herbs include Senecio cannabifolius, and Filipendula camtschatica.

Fauna

The area is known for its very high population of brown bears, and for the extensive networks of streams supporting salmon spawning grounds. Scientists have recorded 104 species of fish in the Kronotsky area alone, and species inventory has only begun. The most common near-shore marine fish gobies, greenlings, pollock, herring, and flounder. Migratory salmon include pink, chum and coho. The rugged coasts are important for colonies of migratory seabirds, particularly those wintering in the area. Important mammals include bear, reindeer, sable, wolves, and sea otters.
Coastal Kamchatka is a breeding ground for the critically endangered Spoon-billed sandpiper.

Protections
