cies Canopy Cover Percent and Habitat Suitability of Gazella subgutrrosa in Different Seasons (Case study: Kalmand plain of Yazd province)

To manage an animal species effectively, it is necessary to identify habitats with high suitability for it; So its population can be preserved by conserving those habitats and planning to manage them properly. For this purpose, the study was done to determine Relationship between rangeland species and habitat suitability of Gazella subgutrrosa in different seasons on the basis of dung groups in Kalmand plain of Yazd province. So, sampling was done using random steady plots with 200 meters long and 2 meters wide and with 2 replications during five field investigation in summer and autumn. Random and control plots were put in different directions and were investigated every 45 days. Finally, all maps needed and information incorporation were prepared and done in ArcGIS9.3. The results showed that there is no difference in two seasons related to dung groups' density. In terms of canopy cover percentage, Artemisia species had a significant increase in presence points compared to random points; Astragalus sp. had also a significant increase in presence points compared to control points. Onopordon sp. canopy cover in absent points and Acanthophyllum sp. in random points were higher than in presence points (p<0.01).according to the prepared map, 23% of the region has topnotch suitability and 47% has second best suitability. Rocks and the regions under human activities were identified as unsuitable habitats. According to the results, it is seems that from habitat variables, species richness, Artemisia cover percent and distance from road are effective on deer habitat.
