Habitat is an important component of biodiversity conservation. Understanding the habitat characteristics to achieve conservation programs is inevitable. The present study was carried out with an aim to identifying microhabitat ecological factors effecting habitat use of Iranian Mountain Steppe Viper (Vipera ebneri) in Alborz Mountains. Sampling was carried out during spring and summer in 2012-2013. Ecological variables were measured in 31 presence and 33 absence plots of 12 ´ 12 m. Results of binary logistic regression analysis showed that hillsides with dense vegetation cover and decimetric stones at the appropriate distance from water sources, are the most important variables in habitat suitability of Iranian Mountain Steppe Viper in the area. The results of this study can fascilitate effective conservation of the remainig populations of Iranian Mountain Steppe Viper through determining factors limiting the distribution of this species as well as identifying and protecting its critical habitats.
