English: The thick-tailed three-toed jerboa Falz-Feini (Stylodipus telum falzfeini Brauner, 1913) is an endemic subspecies with a very small range, which is limited only to the territory of Oleshski sands (or Lower Dnieper Sands). The economic development of the region, especially the creation of forest plantations, has resulted in significant fragmentation and reduction of the jerboa habitats during the last century. The jerboa habitat suitability map was modeled by analyzing the ecological niche on the basis of vegetation indices (computed from Landsat 8 remote sensing data) using geoinformation technologies and multidimensional statistics. The part of the habitat suitability map for jerboa for the region of the Black Sea Biosphere Reserve (Ivanivska Sand Aren and the root part of the Kinburn Peninsula) is shown on the picture. The spatial distribution modeling of the jerboa is very useful for some reasons. It allows to determine which part of the Oleshski Sands is occupied by the jerboa, to analyze the retrospective spatial distributional changes and to assess the risk of the jerboa population extinction, to plan further monitoring of the jerboa population dynamics and to development of the protection measures.
