Ground layer species sustain a variety of plants and animals; and maintain a healthy and resilient forest ecosystem by contributing to ecological functioning, structural support, and biodiversity. The western Indian Aravalli range is noted for its vegetation. Studies from these regions indicate that various environmental factors influence plant diversity and its distributions. The present study examines the impacts of altitude on ground species in Rajasthan's southern Aravalli hill ranges. We conducted field investigations year-round in Phulwari Ki Nal Wildlife Sanctuary, Kumbhalgarh Wildlife Sanctuary, and Sitamata Wildlife Sanctuary at different altitudes. A random transect method was used; five 1m2 plots were laid at every 250m interval. Species’ names and numbers were recorded from sampling plots. Sanctuary-wise species richness, density, and diversity were analyzed and related with altitude. The protected areas of Southern Aravalli do not follow an altitude-specific pattern in ground species distribution. Specific lower altitude ranges had the most species richness, density, and diversity. While altitude showed both positive and negative correlations with respect to ground species richness, diversity and density. The study findings help in conserving and preserving ground layer species in the Aravalli regions of Rajasthan.
