“…Genetic studies show that two genetically distinct clades (mitochondrial haplogroups) of the brown bear occur in Europe: one in southern Europe (clade 1), and the other in the entire north-eastern part of the continent (clade 3) [ 9 ]. Clade 1 is the only lineage in the European Mediterranean since the beginning of the Holocene [ 10 ], and the only one in Bulgaria since the end of the Pleistocene [ 11 ]. The Balkan-Apennine population is unique in its gene pool (clade 1b) [ 11 ].…”

Until recently, the Bulgarian bear population (Ursus arctos L.) was considered one of the significant ones in Europe and one of the few with more than 500 bears. While the numbers of some neighboring populations may be increasing, the Bulgarian population has been on a downward trend since the early 1990s. The probable numbers of the species at the end of the 1980s was about 700–750 individuals. Calculations based on field data from national monitoring and statistical analysis show probable numbers in Bulgaria in 2020 of about 500 individuals (data for the autumn state). This decline is mostly related to poaching due to weaker control activity, the reduction of forest areas and habitat fragmentation. The preservation of the Bulgarian population, which, together with the other Balkan populations and the Apennine bear, has a unique gene pool, is particularly important from the point of view of preserving the biodiversity of the species in Europe.
