Assesment of Habitat Suitability Centeral Alborz Wildsheep (O.o.arkali & O.o.vigneii) Using Maximum Antropy Analysis in Tehran Province

Alborz markazi wildsheep is a migrant species that has several seasonal home rang. This species is classified as vulnerable in red list of IUCN and is classified as a protected animal based on environment conservation law in iran ،Therefor conservation of this species and itshabitats is important in regional and international levels. Analysis relation between species and their environment has ever been a important issue that it is base of modelling. In research we used maximum entropy approach in1392 in Tehran by recorded 350 present points gathered in summer and winter to environmental variables representing geographical and anthropogenical factors of the study area. of summer suitable habitat is 204629 ha and winter suitable habitat is 204471 ha. . in order to survey validation model we used cross validation. Acording to result of studing standard devation of slope and elevation classification, distance of water resource maximum play and orientation minimum play in summer model and in winter model slop and elevation and about orientation sun maximum play and orient east and south minimum play in model.
