Estimating Western mole-vole (Ellobius lutescens) Population Size Using Distance methods In Hamedan Province

knowledge about the animal Population size is important for Wildlife management and is the main requirement tool for management and is the prerequisite for management. Western mole-vole have special life. It has underground life and for this reason the researchers have been little attention to it. Estimating abundance is important and first information that use wildlife management. Therefore study estimating abundance is done for this species.

We use to distance models (T-square sampling and Byth and Ripley). This models don’t need plot and quadrats and Using Seber (1982) model for sample size. Also we use Burnham et al. (1980) for total length of transect and using Ecological Methodology software.

The T-square method, the sample size n=27, density was estimated 56 species per hectare that the 95% confidence interval limits of 38/44 to 63/8 species per hectare (SE=0/0039). The Byth and Ripley method, the sample size n=27, density was estimated 49 species per hectare that the 95% confidence interval limits of 45/2 to 52/6 species per hectare (SE=0/00076).

The final mean population size was considered 50 species per hectare.
