    Deforestation in the Amazon Deforestation in Brazil : This image of the  southern Amazon uses satellite data from the  MODIS on the Terra satellite collected in 2000  and 2001 to classify the terrain into three  separate land surface categories:  forest (red) herbaceous (non-woody) vegetation like  grasses  (green) , and  bare ground (blue) . The Amazon’s  numerous rivers appear white. Brazilian deforestation  is strongly correlated to the  economic health of the country: the decline in deforestation  from 1988-1991 nicely matched the economic slowdown  during the same period, while the rocketing rate of  deforestation from 1993-1998 paralleled Brazil's period of  rapid economic growth.

    Land-cover Categories in CLM CLM land-cover data has total 15 categories called PFTs (Plant Functional Types). Seven primary PFTs (needle-leaf evergreen and deciduous tree, broadleaf evergreen and deciduous tree, shrub, grass, and crop) are defined based on 1-km IGBP (International Geosphere-Biosphere Program) land cover dataset and University of Maryland tree cover dataset. These primary types are expanded to climate regimes (arctic, boreal, temperate, and tropical), using temperature and precipitation-based rules, to obtain the 15 total PFTs. A limitation of the current version of the CAM/CLM model is that only four PFTs for each grid cell are used. The four PFTs chosen for each grid cell are the PFTs with the highest percent coverage of area.
