Evaluation Ecological Niche Factor Analysis in Modeling Suitability Habitat of Boar (Sus scrofa, Linnaeus, 1758) in Arak Jassib Wildlife

The information about the geographical distribution and habitat selection is the core of the conservation and management of threatened species. Habitat destruction is one of the major threats to biodiversity. Therefore, knowledge of the need for biological and identify favorable habitats for wild boar have very important role in the way of habitat species management. This study is going to model the habitat of wild boar in Jassib wildlife sanctuary and determine the most important environmental factors affecting the choice of species-habitat. The provided survey has conducted in one-year period in four different seasons of the year. So Ecological Niche Factor Analysis (ENFA) and software Bayvmpr was used. Information layers used as effective variables on the species consisted of, slope, aspect, elevation, distance from the source, the distance from the village, away from canals, roads, vegetation index, vegetation type, land use and distance to human development, respectively. The results of the analysis showed that ecological niche factor, Boyce index values for average algorithm median, mean geometric distance, the harmonic mean and minimum distance during four seasons (spring, summer, autumn and winter) and a one-year period is not really enough. Boyce can be concluded based on index values; the accuracy is not very good production. The reason for this variance is high, indicating low precision and low predictive power of the model. Based on index values of Boyce it can be concluded that the accuracy production is not very good. The reason is for the higher variance which indicating lower precision predictive power of the model. Thus, ecological niche factor analysis model is less functional due to low quality and small-scale habitats. The ecological niche factor analysis is not a good way to study the habitat of Jassib hogs Wildlife. Therefore, identification of species distribution and dispersion of wild boar in Jassib wildlife sanctuary have paly important role as a facilitator for executives and environmental experts and farmers in order to achieve an efficient management to reduce conflict as well as identify areas that are at high risk damage and their protection must be in a priority as well.
