Lorestan province, as a predominantly mountainous region, covers important part of critical habitats of Persian leopard (Panthera pardus) in west of Iran. However, there is little information on geographical distribution of the leopard in this province. This study aims to identify suitable habitats of the Persian leopard in Lorestan province, using an ensemble model consisting of seven species distribution models. The ensemble model identified 6,185 km2 (21.85%) of the study area as suitable habitat for the Persian leopard. Distance to conservation areas (30%), distance to village (29%), distance to farmlands (11%), annual precipitation (8%) and distance to forest (7%) made the highest contribution to the model performance. About 49% of the identified suitable habitat covered by conservation areas. Establishing more conservation areas in suitable habitats and re-evaluation of the network of conservation areas are crucial strategies to conserve endangered populations of the leopard. Many large carnivores, due to their large home ranges, depend on habitat patches outside protected areas and corridors between them. Thus, conserving the habitat patches and connectivity between them are crucial. Monitoring and surveillance of habitats, using effective conservation strategies, and promoting local community involvement are other important issues.

This study was conducted to determine habitat connectivity and road crossing area for the Persian wild ass (Equus hemionus onager) in the Bahram-e-Goor Protected Area. In this research, habitat suitability modeling was carried out using 57 presence points of the species and six environmental layers implemented in the Biomod2 package in the R software based on four species distribution models. Then, the ensemble map obtained from the distribution models was used for habitat connectivity modeling using electrical-circuit method. Finally, the coincidence rate of road crossing with road collision points was assessed. Ourresults revealed that distance from moderate rangelands, distance from roads and slope had the greatest impact on habitat suitability of the Persian wild ass. Furthermore,results of the connectivity modeling revealed that there were high current movements of Persian wild ass individuals between Qatruiyeh National Park and western parts of the Bahram -e- Goor Protected Area. Eventually, seven road collisions were found to be in high coincidence with the modeled current movement along the west border of the Bahram -e- Goor Protected Area.This research highlights the necessity of provision of road crossing facilities (i.e., warning signs and lights, and speed control for vehicles) for conservation of the Persian wild ass by the Department of Environment in the study area.
