There has been no attempt to to distinguish natural from plantation cover in this case. It is therefore inevitable that some of the 'tropical dry forest' in this map is in fact plantation forest occupying a climate space that may have originally supported tropical dry forest.
This map has not been ground truthed. In particular, the assumption that 'forest' can be defined by a restriction to 40% canopy cover has not been verified with respect to dry forest.
The tree cover map (MODIS) is a classified satellite image. There is scope for error, which has not been evaluated for this application.
The arid zone map was not delineated to the same degree of accuracy as the ecoregions map, so there are disparities in edges which are clearly intended to indicate the same physical boundaries. Also, there are some distinct curves: see the dry forest defined at the edge of subSaharan Africa.UNEP-WCMCSpatial Analysis Unit+44 (0) 1223277314+44 (0) 1223277136219 Huntingdon RoadCambridgeCambrigeshireUKCB3 0DLspatialanalysis@unep-wcmc.org20111013ArcGIS Metadata1.0UNEP-WCMCSpatial Analysis Unit+44 (0) 1223277314+44 (0) 1223277136219 Huntingdon RoadCambridgeCambridgeshireCB3 0DLUKspatialanalysis@unep-wcmc.org\\wcmc-data-01.internal.wcmc\gis\SpatialAnalysisUnit\Datasets-May2006\trop_dryf\tropdryfEnterprise Geodatabase Raster DatasetGlobal tropical dry forest2006UNEP-WCMC for the publication "A global overview of the conservation status of tropical dry forests.
