Service Description: We present a new global distribution map of tropical dry forest derived from the recently developed MODIS Vegetation Continuous Fields (VCF) product, which depicts percentage tree cover at a resolution of 500m, combined with previously defined maps of biomes. This distribution map was overlaid with spatial data to estimate the exposure of tropical dry forests to a number of different threats: climate change, habitat fragmentation, fire, human population density and conversion to cropland. The extent of tropical dry forest currently protected was estimated by overlaying the forest map with a global data set of the distribution of protected areas.

This grid dataset shows the estimated maximum distribution of dry and seasonally dry topical forest. It has a resolution of ~500m. It is derived from the WWF biome map, the MODIS canopy cover dataset and limited to the tropical zone. This dataset was used in the publication " A global overview of the conservation status of tropical dry forests, 2006. Miles, L., Newton, A., DeFries, R., Ravilious, C., May, I., Blyth, S. Kapos, V. and Gordon, J. Journal of Biogeography 33: 491-505
