Population dynamics trends of four Artiodactyla species in Sarnena Sredna Gora Mts (Bulgaria) based on hunting statistics

. Annual harvest hunting data and counting statistics from 2009 to 2019 were used as methods for assessing changes in four Artiodactyla species population trends. The study area covers approximately 100,000 ha territory from Sredna Gora Mts. The results showed trend for a stable increase in the Red Deer population, because of provided conservation measures. The Fallow Deer could be considered an occasional species. An increase in Roe Deer number was observed, with steeper rising between 2014 and 2018, followed by a strong decline in 2019. The Wild Boar number was changing significantly over the years, reflected in peaks and falls of number shot individuals for the study period. Tracking and comparing the hunting bag statistics data for ungulates in the study area for a longer period would give a clearer picture on their population trends and would help in selecting conservation measures.
