Land Cover/Veqetation Vigor Changes for SITE ONE 
Recognizable patterns in spectral signatures and 
the geographic distributions of the spectral 
classes were used sis the basis for generating the 
final classification. Statistics for percent land 
cover for the entire area are not considered 
accurate because of the extensive cloud/smoke/haze 
cover in the 1987 data. Thus, statistics for the 
six sub-sites (Table 2) are presented as a means 
of indicating representative land cover variations 
throughout the study area in haze-free locales. 
Land cover maps were generated for each of the 
sub-sites for both dates with CLOSED FOREST cover 
represented in black, OPEN FOREST cover in dark 
gray, and NONFOREST in light gray (with clouds 
represented in white). To illustrate land cover 
and changes in southwestern sections of the 
Central African Republic, sub-sites from within 
the closed equatorial rain forest (Figures 3 and 
4 of Site 1-A), a location on the boundary between 
the closed rain forest and the grasslands (Figures 
5 and 6 of Site 1-B), and a sub-site with large 
patches of recently burned grasslands (Figures 7 
and 8 of Site 1-C) are presented.
