Modeling the habitat suitability for three key species in forest habitat using HEP model (Case study: Mazandaran forest areas)

Habitat is the most important factor for wild life and plant life that is necessary to protect it for sustainable development. The most important factor of threat and destruction plant and animal life is related to habitat`s changes and insecurity. With habitat Modeling we can estimate wild life species habitat suitability on a large scale without collecting a lot of information about physiological and behavioral characteristics details. With respect to the importance of habitat and problems that caused by their destruction, habitat survey and exact assessment is emergent need more than ever. In this research effective parameters have been studied in 4 forest habitat in north of country, GhadiKola, Abbandankash, Erus, Lajim, for determining habitat suitability with HEP model. This model is a quantifiable method for assessing habitats that with the lowest data, the best and most desirable result can be achieved. After library studies and checking selected stations, trapping was done in the form of transect. And then 3 indicator spices including (Lampyris Noctiluca), (Crocidura caspica / Caspian Shrew) and (Accipiter gentilis) were chosen and finally with calculating habitat suitability index (HSI) the suitability situation of each four stations was compared. Results show that each of the four stations has had a relatively good utility. in general, calculate the average utility rate in4 stands, three of them include: abbankash, erus and lajim have had the same utility with value of 67 and 68 percent's but gladiola’s station whit amount of 87 percent has had the highest utility rate.
