Swamps as a self-regulated natural system

Swamps are stable ecosystems. Their stability is provided with the complexity and a substantial number of organisms that constitute them: animals and birds, fishes and insects, plants, fungi and lichens. They play the first and foremost role for those species which spend only some part of their life in the swamps. Plenty of birds nest and feed in the swamps such as black grouse, wood grouse, hazel-grouse, willow grouse, whose forage reserve is berries growing in the peatbogs. Swamps are the main places where ducks, geese, cranes, sandpipers, herons and other birds nest.
