The region noted for its sparse forests of Betula ermanii ("Stone birch"), and also for extensive tall-herb meadows.

The main floral communities are dwarf forest (primarily Alder and Siberian Dwarf Pine), sparse forests (Ermine birch and Japanese white birch), tundra (moss, lichen and shrub), and some meadows.

Common tall herbs include Jacobaea cannabifolia (Aleutian ragwort), and Filipendula camtschatica.

[6] The area is known for its very high population of brown bears (over 15,000 individuals),[7] and for the extensive networks of streams supporting salmon spawning grounds.

Important mammals include bear, reindeer, sable (now protected in Kronotsky), wolves, and sea otters.
