Forest ants of the genus Formica are legally protected animals. With the environmental services they provide, ensure ecological stability of forest ecosystem and are an important part of ecosystem. This work was focused on the study of ecological linkages (trofobiosis, myrmecochory and myrmecofily) and mapping damage nesting by woodpecker and wild pigs. Their destructive activities in the studied area are very high. The work also oriented on gaining a new approach to protect the ants of the genus Formica, which is based on the Red List of endangered species in the Czech Republic. Existing species protection is extended to protect the environment and the creation of a comprehensive protection.
