Abstract
One step in wildlife management is knowing as target population density and that is required cognition of species dispersion pattern in landscape level. In this research, the dispersion and density of brown bear (Ursus arctos syriocus) with use of the Standardized Morisita Index (SMI) and Adaptive cluster sampling (ACS) Were determined in Arsanjan County range in Fars province. Field work and cencus of presence signs does with use random sample in 3 × 3 km cells. Total of sampeling grid in study area include 300 cells. Results SMI showed that dispersion pattern brown bear is clumped and individuals that most aggregationed in koh khom non hunting area. The Results of ACS related to active winter dens showed the brown bear density was 0.031 bear in each cell and 0.0034 bear in kilometer square. Therefor recommendation winter dens is appropriate index in evaluation brown bear population and use in density estimate this species in other areas.
