Abstract: The presented paper discusses the issue of the bat community activity in the model area (SACMartinský les, SW part of the SlovakRepublic) and the impact of selected factors on it. Since we studied the foraging activity of bats, we focused on the bat habitat preference and ecological classification of bats in connection with foraging habitats. We also defined the current landscape structure, including the evaluation of the percentage of 22 elements identified in the studyarea. We describe the detailed attribute and the process of selecting specific sites where the bat-detectoring took place. Two criteria (age of forest stands and the number of tree cavities) have influenced this choice. The bat activity on 15 particular detecting points depending on the landscape structure was evaluated. The percentage of the landscape structure elements within the radius of 100 m from each monitoring site was evaluated too. In the selection of foraginghabitats, the presence of linear elements was of greater importance than old forest stands.
