Introduction: One of the potentials of arid and semi-arid natural ecosystems is that these regions are prepeir area for grazing animal species. These species adopted with dry climate and conditions and they have high value. Wild goat and wild lamb such as the importance index of mammals in mountain region in a lot of dry habitat. Therefore, there isn’t enough studding about contract relationship and their habitat in Hormozgan. On the other side, these animals are one of the main food resources for carnivores such as tiger.  Tiger, goat and lamb are important potential in arid and semi-arid ecosystems. Habitat suitability of wildlife and determining suitability for livestock investigate relationship between species and ecological factors. These modals today are such as instrument for using in protection biology and their result has high utility in different management planning for protection and rehabilitation wildlife population in protected area. It is necessary for permanent and sustainable using from these resources is evaluate ecologic potential and determining arid and semi-arid land suitability. Geno national park because of habitat degradation and hasn’t enough protection of wildlife degraded to protected area in 1351. This region is ecoton and it is inter pole of 3 grow areas (Omani Gulf, Iran – Tourani & Zagros) from 5 grow areas in Iran. Geno has more than 60% of plant species in Hormozgan, it has 517 plant species. Because of climate factor and human degradation exchange and wild life density that use forage decreased. Follow that density of wildlife decreased. From IUCN some animals are in vulnerable list (IUCN,2009). This fact show that we need to decide for arid and semi-arid areas that they have wildlife habitat for protection and improve herbivores and mammal’s species population especially in protected area. It cause to prevent degradation and decreasing ecological potential area.
Material and methods Geno protected area with 44598 ha with 27 15 49 – 27 29 28 north and 56 18 15 – 56 57 5 in 30 km to west north of Bandarabass. Geno has mountain with 2345 m that surrounded by plain and open hills. North of Geno is Tang Bagh river, Agah harbor Chimangan, Geno gerd tiver, Soltan Shah land and Sadgaz in east, Bandarlengeh to Kal river. Geno is far 30 km from center of Bandarabas from 1351 under manage of environment protection organization. This study was down according FAO evaluation principals for determining livestock and wildlife grazing suitability in Geno protected area. For determining wildlife grazing suitability modal, at first based map and second sub modals prepared and then we overlaid maps. Finally region with high suitability (S1), moderate suitability (S2), weak suitability (S3) and not proper (N) determined. Although all articles effect on arid and semi-arid ecosystems suitability, but investigation of all factors are not possible. So 3 factors are main article from final wildlife suitability modals according FAO principals (Arzani, 2006).
   a) soil Sensitiviti to erosion    final modal of erosion HASASIAT soil was prepared according field studding and observation investigation with EPM.
b) Forage production and determining grazing capacity: in production suitability modal, total production and allowable  production in every type were calculated. Total production measured by cut and weight method (Milner and Hogs, 1968). We determined wildlife daily requirement forage for different wildlife species and then wildlife grazing capacity determinded.
c) Water resources. Place of water resources by GPS registered in ArcGIS and distance of water resources map with buffer prepared. After overlaid quality and quantity and distance of water resources we identify water resources wildlife map.
Discussion and conclusion: In our study we use two parameters one ecological (slope, aspect, dem, soil, plant production, water resources, wildlife distributions) and one sub structural (distance to city and service facility and roads). FAO modal for determining suitability. Results show that in Geno protected area we haven’t S1 and S2 area and we have 27.84 %  S3  or 12415.46 ha and  32182.54 ha or 72.16 % area non suitable area. So according to finding we must manage and protect more. Although exporting modals livestock were interred wildlife suitability modals.  Allowable use harvesting level, forage production, livestock more grazing and decreasing water resources are limited factors for wildlife grazing suitability. If we don’t protect and we haven’t good and principal program our suitability trend from S3 to N.
