The spatial and temporal aspects of the habitat suitability of the European Souslik (Spermophilus citellus L.) in an area in Sredna Gora Mountain (Bulgaria) was investigated. Data from Landsat satellite imagery were used for modelling changes in the habitat suitability of the species from 1985 till 2018. Linear Regression Analysis showed that spectral bands represent not only the spatial heterogeneity of the landcover, but also the temporal changes of two climatic parameters – monthly temperature and rainfall amount. The obtained results show that the habitat suitability of the European Souslik increased during the studied period. The methodology used here based on statistical modelingis applicable to long-term monitoring and evaluation of the role of land cover change as a result of the human activity and the climate change on the habitat suitability of the European Souslik.
