with Forest Type Maps
نویسنده
چکیده
Fragmentation of forest types is an indicator of biodiversity in the Montreal Process, but the available national data permit assessment of only overall forestland fragmentation, not forest type fragmentation. Here we illustrate how to localize national statistics from the 2003 National Report on Sustainable Forests by combining state vegetation maps with national forestland fragmentation maps. The degree and scale of fragmentation of diff erent forest types can be gauged from the amount of forestland that meets certain fragmentation thresholds at multiple scales of analysis.

متن کاملAssessment of geostatistical and interpolation methods for mapping forest dieback intensity in Zagros forests
During recent years, oak decline has been widely spread across Brant’s oak (Quercus Brantii Lindl.) stands in the Zagros Mountains, Western Iran, which caused large-area forest dieback in several sites. Mapping the intensity and spatial distribution of forest dieback is essential for developing management and control strategies. This study evaluated a range of geostatistical and interpolation m...
