Birds are common here, including black hawk, cheglok, sea-eagle, vyakhir, coast swallow, the eastern Zavirushka bluebird, finches, seagulls, and krachki. The area is also the habitat of the quick lizard and raccoon dogs.
Felling trees is forbidden in this territory and human visits are limited to fishermen, hunters, and scientists observing the biocenosis.
