Home Range and Habitat Selection of Feral Horses (<i>Equus ferus</i> f. <i>caballus</i>) in a Mountainous Environment: A Case Study from Northern Greece

Abstract

The spatial ecology of feral horses (Equus ferus f. caballus) in Greece has never been studied before, including home range size and habitat selection. We tracked two mares fitted with global positioning system collars between September 2020 and August 2021 in a portion of Mount Menoikio in Central Macedonia, Northern Greece. We used K-select analysis to assess habitat selection for the study period by combining location data with several environmental variables. The mean home ranges for horses varied from 26.72 km2 (95% Minimum Convex Polygon; SE = 0.442) to 27.84 km2 (95% Kernel Density; SE = 1.83). Both horses selected areas with flat and smooth topography near natural grasslands with high green productivity. Conversely, they avoided areas near broadleaved forests and pastures, as well as at north-facing aspects. Overall, suitable habitats corresponded to a small portion (15.1%) of the available habitat. Our findings could assist land managers in mapping primary horses’ habitat in the wider region and implement management regimes that will aid in preserving natural grasslands.
