Pfad der Pioniere 8: Artenvielfalt
One fifth of the animal species living in the forest and around 2500 species of fungi depend on deadwood. Totzholz ensures that enough beneficial organisms are available.
In the natural forest reserve, there is more dead and waste wood than in an average Swiss forest. The beneficial insects prevent e.B. as natural antagonists of the bark beetle its mass reproduction.
Capercaillie roam the Crap Furò Natural Forest Reserve. Here the rare birds find ideal living conditions. The conifers and shrubs offer the Auerhun protection from enemies. They use structures such as lying deadwood as cover from the weather and as a place to rest and sleep. In summer, they feed on berries and herbs in the lush layer of plants of the open forest. In winter, they live mainly on trees and eat needles.
The main threats are disturbances caused by humans and habitat loss due to changes in forest management. About 500 capercaillie pairs still live in Switzerland, a third of them in the canton of Graubünden. for their protection, the natural forest reserves are not allowed to leave the paths during the Winder half-year.
