Markazi province with its elevated mountains is a suitable habitat for the wild goat(Capra aegagrus) such that the species has been chosen as the symbol of biodiversity in the province. The fragmentation of habitat due to the human-initiated activities is one of the major threatening factors against the species viability. The study is under taken using the MAXENT method based on the maximum entropy or near to reality approach with 10 different variables. The study results indicate that a 1698.78 Km² area equivalent to 11% in the southern half of Markazi province covers a favorable habitat for the wild goat. The ROC model specifies that the validity of habitat suitability model is 0.978 indicating the superior performance of MAXENT method. Among the development variables, the highest impact on the wild goat ecology is assigned to distance to cities variable (20Km) while the lowest impact is related to distance from unpaved road variable. And among the ecologic variables, the highest impact is determined for slop variable (20%) and the lowest impact is related to height variable..The protection of the extant population, inter-regional corridors, live capturing, sending the wild goat from other regions to Jasb and Rasvand, and restoring the wild goat in Alvand and Bazerjan in Tafresh, Iran.
