Until recently, the Bulgarian bear population ( 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.
直到最近，保加利亚的棕熊种群（L.）都被认为是欧洲数量较多的种群之一，也是为数不多的拥有超过500只棕熊的种群之一。虽然一些邻国的棕熊数量可能在增加，但自20世纪90年代初以来，保加利亚的棕熊数量一直在下降。20世纪80年代末该物种的可能数量约为700 - 750只。根据国家监测的实地数据和统计分析进行的计算显示，2020年保加利亚的棕熊可能数量约为500只（秋季统计数据）。这种数量下降主要与控制活动薄弱导致的偷猎、森林面积减少和栖息地破碎化有关。保加利亚的棕熊种群与其他巴尔干种群以及亚平宁棕熊一起拥有独特的基因库，从保护欧洲该物种的生物多样性角度来看，保护保加利亚的棕熊种群尤为重要。
