One of these projects was transfer Deer to Ashk Island of Dashte Naz. In this study for estimation rate being used of exploitation the plants after identifying the priority species was done by cutting and weighting method the measuring production and difference between two season in order to rainfall the get tested rate of change in production. This difference can have presented from view available plant cover in Island and difference habitats and also production volume priority plant species in two season spring and summer. Spring production nutrition priority species which preferred by Fallow Deer (including 6 species) in 4 habitat types (Plane, High Slope and Rocky, Edge wellhead and East Edge, North Edge) estimated 284531.238 Kg. While the spring production volume estimated for priority species involving 7 types of food stuff 241367.580 Kg. Spring Sampling done in May that in this month growth of have been low plant covers, and so production value naturally doesn't very difference by production in summer which has been sampling in September.
