forest roads are directions in natural habitats that used to transport wood products, secondary forest products and recreation. constructing forest roads causes trees clearing with specified width thus lead to direct or indirect changes in forest ecosystems and forest environment. this study aims to assess the changes of diversity and richness indices in main and secondary forest roads in a par...

in land use planning, mapping the present land use / land cover situation is a necessary tool for determining the current condition and for identifying land use trends. in this study, in order to provide a land use/ land cover map for ilam watershed, the irs-1c image data from 25th april 2006 were used. initial qualitative evaluation on data showed no significant radiometric error. ortho-rectif...

introduction ownership is an important element for sustainability development in natural resource management. rangelands vegetations are important factor for produce in traditional herding therefore recognition of different utilization methods and management of this vegetation resource production for animal grazing and rangelands condition is very important. so this research carried out in 2009...

     In recent years, large rangeland areas have been destroyed for various reasons, so that its negative impacts on local people's income and sustainable livelihood are become significant. Due to the fact that signs of negative or downward trends in the rangelands condition are being revealed prior to the complete degradation, a study was done to identify these sings and evaluate their importa...
