Ancient broadleaved forests, mainly situated on the Ulyasy ridge, part of the Talysh mountains, but one small area (81 ha only) is in the lowlands. There is also a reservoir (400 ha).
Breeding birds include Ciconia nigra (probably still 1 pair), Hieraaetus pennatus (1+ pair), Otus scops and four woodpeckers, Dendrocopos syriacus and D. medius being common. Milvus milvus: status uncertain, mainly a very rare winter visitor. The site holds a good representation of restricted-range subspecies (chiefly passerines).
