Ecotones are zones of gradual changes from an ecological system to another. Ecotones monitoring could be important to find out the reason for changes and limits. In this research satellite data were used to analyze the ecotone boundary in Fars steppic rangelands using IRS LISS III and Pan data of year 2006. The real vegetation […]
One of the influential tools concerning the rangeland and vegetation sciences is the technology of remote sensing and satellite data. Satellite data have played essential roles in preparing the needed information for studying the vegetation. Vegetation has been widely recognized as one of the best indicators for determining the land conditions. Using vegetation indices is […]
Biological invasions form a major threat to the provision of ecosystems products and services and can affect ecosystems across a wide spectrum of bioclimatic conditions. Therefore, it is important to systematically monitor the spread of species over broad regions. It has long been recognized that remote sensing and geographical information system could contribute to this […]
