The three breeds are part of the natural, cultural and historical heritage of Bulgaria. The main goal of these projects is: saving the traditional way of their breeding as a symbiosis among them and their living environment. The long-term project started in the beginning of 2001 and is supported by: The SAVE Foundation, Frankfurt Zoological Society and private donors.
