Bulgarian Biodiversity Foundation (BBF) was established in 1997 as the successor of the established in 1994 Bulgarian – Swiss Biodiversity Conservation Programme (BSBCP). Since its creation for more than 15 years BBF has supported nature conservation in several key regions of Bulgaria – Pirin, Dobrudzha, Ropotamo, Central Balkan Burgas wetlands, Strandja, Eastern Rhodopes, Osogovo and Belasitsa.

Individually and in partnerships with others BBF developed 12 Action Plans for endangered species from the IUCN Red List, prepared the documentation for declaring /proclamation of three Nature Parks, 11 protected areas and three new Ramsar sites and assists the establishment of 6 information and nature conservation centers.
