%X Determining and monitoring habitat size preferred by species and variables that play a role in their habitat preferences are important to carry out conservation and management activities for wildlife species. The collection of these data with traditional field inventory methods is a process both costly and time consuming. In contrast to these methods, the use of satellite data providing continuous data for large areas provides both time and cost benefits. For this reason, in this study carried out in Akda£¿ (Simav) region, it was aimed to determine the habitat size preferred by Roe deer (Capreolus capreolus L.) and the variables playing a role in this preference with Landsat-8 OLI satellite image. During field studies conducted using indirect inventory techniques, 32 presence data of species were recorded. By using Definiens software, multiresolution segmentation was applied and the satellite image was divided into different patches. Following this, the Chessboard Segmentation was applied and the satellite image was divided into different grids with 16, 64, 256 and 1024 pixels. Within each grids, 15 different variables (9 different algorithms with Definiens software, 6 different patch parameters with ArcGIS software) were obtained. By using MaxEnt, models are created and mapped for each grids size using the presence data of species and the variables obtained from the satellite image. The training data set AUC and the test data set AUC values for models of grids size with different pixel numbers were obtained as 16 (0.712, 0.698), 64 (0.864, 0, 825), 256 (0.802, 0.795) 1024 (0.792, 0.779). Among the obtained models, the model created for grid with 64 pixels was selected as the most suitable model for the species. The variables forming the model are determined as Contrast to Neighbor Pixels (2), Edge Contrast of Neighbor Pixels and GLCM entropy. Finally, with this study, it was determined that habitat size preferred by species and variables that play a role in their habitat preferences can be accessed by the satellite dat
