Echis carinatus, commonly known as the saw-scaled viper, is one of the most significant members of the Viperidae family in the arid and semi-arid regions of Iran. Due to its ecological role, predatory behavior, and wide distribution, it has drawn considerable attention. This study aimed to evaluate the potential habitat of this species using the MaxEnt (Maximum Entropy) model. Occurrence records along with 19 environmental variables were collected, and through principal component analysis, eight key variables were selected. The modeling results indicated that temperature, precipitation, and elevation are the most influential factors affecting the distribution of E. carinatus. The model's performance, with an AUC value of 0.882, suggests high predictive accuracy. The generated habitat suitability maps identified southern, southwestern, and parts of central Iran—particularly the provinces of Kerman, Fars, and Bushehr—as having more favorable habitats. These findings can contribute to more effective management and conservation planning, especially in the face of climate change and habitat degradation. Utilizing MaxEnt as a powerful modeling tool enables more accurate predictions of species distribution and supports biodiversity conservation efforts in vulnerable regions of Iran.
