We conducted spring and autumn surveys of Caucasian black grouse Tetrao mlokosiewiczi throughout northeastern Turkey during 2004-2005. Birds were found at 45 locations, 29 of which were previously undocumented. The species appears to occur in four geographical units with differing degrees of connectivity and isolation, and is still under pressure from illegal hunting as well as habitat deterioration and fragmentation, principally as the result of road construction in mountain areas. A preliminary analysis of the degree of overlap between grouse populations and protected areas shows that the protected areas network should be reviewed. The data collected during the course of this survey are being used to develop a model for predicting the distribution of black grouse in northeastern Turkey and to prepare a National Species Action Plan. A detailed ecological study of the Caucasian black grouse is required to develop habitat management recommendations for the species.
