Conversion of life zone to ecologically less valuable land cover in Iran
The life zones of Iran were mapped using the Holdridge system based on biotemperature and precipitation maps of Iran. Conversion of each life zone to an ecologically less valuable land use/cover was determined based on comparing the life zones and the current land cover of Iran. Results showed that...
