Species diversity is one of the levels of biodiversity that encompasses a variety of Fauna and Flora. Haftad-Gholleh National Park located in central of Iran is inhabited by species diversity. This study identifies the animal species of the safe valleys of Chekab and Sibak Haftad-Gholleh National Park and this method calculates the species diversity indices for the area using ecological methodology software. Animals were recorded and censored using images from the local telephoto camera trap. Species diversity indices (richness, heterogeneity, homogeneity) and within habitat, between habitat and regional diversity (γ, β, α), and Morista similarity index were used to estimate and analyze the similarity of fauna with the Chekab and Sibak valleys. The results showed that 22 species were recorded in Haftad-Gholleh area, 11 of bird species, 10 mammals species and 1 amphibian species. In general, the highest species richness is related to the Sibak Valley and the least richness to the Chekab Valley. According to heterogeneity and homogeneity indices, the overall trend of species diversity in the Sibak and Chekab valleys was initially decreasing and then increasing. The similarity index between Sibak and Chekab valleys is 0.98, indicating high similarity between the two valleys. The highest α, β and γ diversity indices belong to the Sibak Valley and the least to the Chekab Valley.

This study in order to introductory study of ecological charactristics some in nesting habitat of Eurasian Penduline Tit Remiz pendulinus in Khondab Shara area of Markazi province was conducted from April to July 2018, Using of linear and point transects and statistical methods, with eight variables such as: Percentage of tree crown cover, diameter at breast height, depth of river under the nest dangling, distance from the road, distance from agricultural land, distance from the village, nest height from the surface of water and land and nest size. Results showed as if Penduline Tit’s nests 17 was observed in the area. Nests were active eight and inactive nine. The variables of tree crown percentages, diameter at breast height, river water depth and distance from the village have a significant correlation with the nesting habitat of the Pendulines and their activeness. Reduced annual drainage of the river and agricultural land development threatened the nesting habitat of the Pendulines and decline the population size of this bird.

Abstract Persian squirrel (Sciurus anomalus) is one of index mammals of the Zagros Oak Forests, as for is very poor of the natural forest cover in Markazi Province, therefore existence of trees dominant typeof species Quercus Brantii persica in the Forest Reserve Area of shazand is of great importance for the regeneration of this species.The study was using MaxEnt and statistic methods with Seven variables i.e. tree height, diameter at breast height(DBH), cover crown, distance from roads and agricultural land, distance from the nearest tree, the number of trees has holes, and Frying rate of oak trees, and 60 hypothetical of simulated points of squirrel. The results indicate that an area of 6.4 ha, equivalent to 39%, in the forest reserve area of shazand is habitat suitable for the Persian squirrel. The model validity is 0.845 revealing the excellent performance of MaxEnt method. According to, the habitat conditions of available does not exist of the possibility of regenerationof the Persian squirrel in the Forest Reserve Area of shazand now. The number of trees has holes, diameter at breast height, distance from the nearest tree, Frying rate of oak trees, cover crown and are respectively known as the variables with the greatest impact on habitat of Persian squirrel.
