Mangrove degradation is one of the most common issues in coastal areas Java, which can cause ecological impacts and even disadvantage for local community. The mangrove forest be identified based on vegetation analysis results, could potentially contribute to ecosystem management rehabilitation programs areas. Mangroves Keboromo Village was cultivation area, but often get damaged by ocean waves....
Remote sensing has been considered as an appropriate tool for temporal monitoring of some natural phenomena. Ardestan Region is prone to land degradation and masked by sand sheets, sand dunes, clay flats, desert pavement and different kinds of salt crust due to dry climate. To study the trends of land degradation in last three decades, four satellite data sets of Landsat MSS, Landsat TM, Landsa...
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...
This report contains the results of a 6-year project conducted by the U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station and U.S. Environmental Protection Agency, Office of Research and Development on stream incision and meadow ecosystem degradation in the central Great Basin.

Vegetation trampling resulting from recreation can adversely impact natural habitats, leading to the loss of vegetation and the degradation of plant communities. A considerable primary literature exists on this topic, therefore it is important to assess whether this accumulated evidence can be used to reach general conclusions concerning vegetation vulnerability to inform conservation managemen...
The turbidity of lakes is generally considered to be a smooth function of their nutrient status. However, recent results suggest that over a range of nutrient concentrations, shallow l&es can have two alternative equilibria: a clear state dominated by nquatic vegetation, and a turbid state characterized by high algal biomass. This bi-stability has important implications for the possibilities of...
