Wild goat (Capra aegagrus) is an indicator species used for assessing the health of the habitat. In this study, the population of wild goats, were analyzed in Arasbaran protected area in the three sub zones include; Shah Heydar – Daraghzi, Vineq, Tazakend - Anza. The results of the annual census surveys and extensive field visit showed that linear transect method is reasonable for the census of the species in the National Park and Protected Area of Arasbaran, However, the need to revise and supplement besides using it to compare and determine the error for clarification of results is necessary. Census statistics for the eight-year observations show that approximately 50% of the total population of Goats focus in habitats of Daraghzi – Shah Heydar. Statistical analysis of census data show that a significant difference (p<0.5) in the total number of goat census from Arasbaran protected area in 2013 compared to 2006-2008. Declining of goats population density were observed in all three habitats in Shah Heydar – Daraghzi, Vineq, Tazakend – Anza, but the decline of the population density in Daraghzi – Shah Heydar habitats is higher in the charts that Steep gradient of population, continues decline with a sharp trend since 2009. If the conflicts, threats and habitat destructions do not resolve, insecurity Increased and reduced viability of the species presence in all habitats for the near future is conceivable. These results in a systemic approach, to planning for management and conservation of the region's ecosystem will be enough and possible changes or modifications will facilitate the protection of the ecosystem.
