Geolocation tracking to monitor spatial distribution and habitat selection of cows, horses and sheep grazing in mountainous areas
Precision Livestock Farming (PLF) technologies offer an opportunity to monitor livestock, enhancing farmers' decision-making for improved control, better animal performance, and reduced environmental impact through proper management of pasture areas.

| description | Precision Livestock Farming (PLF) technologies offer an opportunity to monitor livestock, enhancing farmers' decision-making for improved control, better animal performance, and reduced environmental impact through proper management of pasture areas. The objective of this study was to assess the potential of data provided by commercial geolocation collars, along with open data resources such as information on natural habitats, topography, and vegetation, to detect grazing preferences of mountain livestock. We monitored 240 animals from three different herds and species (140 cows, 50 horses, and 50 sheep) during the grazing season (6 months) using geolocation collars in the Alt Pirineu Natural Park (80,000 ha), located in Catalonia, Spain. Animal distributions were analysed spatially and temporally across different seasonal periods (Spring: May-Jun, Summer: Jul-Aug and Autumn: Sep-Oct). Geolocation data were used to assess livestock preferences and avoidances regarding different types of terrain, land cover, and vegetation, estimated using Jacob's selection index (JSI), a metric indicating whether animals use a particular area more or less than expected based on its availability. Additionally, we examined the influence of these environmental factors and the distance to water sources on animal distribution, and we identified high-density grazing hotspots. Results indicated that cows and horses positively selected areas with lower altitudes (JSI = 0.29 and 0.17, p < 0.05) and gentler slopes (JSI = 0.38 and 0.22, p < 0.05), whereas sheep preferred higher altitudes (JSI = 0.10, p < 0.05). Only cows showed a preference for areas with bare or dispersed vegetation. In general, all three species selected land covers such as open forests, meadows, wetlands, and water points, but changed depending on the season and species. The distance to water was greater for cows and sheep, particularly during the summer, whereas only horses showed a strong dependence on proximity to water sources. Finally, we identified and compared high-density grazing hotspots among the three species. These findings reveal not only interesting heterogeneity in distribution patterns among species sharing the same area, but also clear seasonal differences. In conclusion, data automatically collected from geolocation collars demonstrate strong potential for studying livestock grazing preferences, particularly in remote or hard-to-access mountainous areas. This information improves our understanding of livestockenvironment interactions without requiring physical presence and can be effectively applied to support extensive grazing management. |
