Change in Land Cover for SITE 1-A 
Within the 43,200 hectare sub-site, 86 percent of 
the area remained unchanged over time, with 
approximately 96 percent of the area classified as 
closed rain forest experiencing no change over the 
fourteen year period of this study. These 
results, combined with visual image 
interpretation, suggest that the large, contiguous 
patches of rain forest in this portion of the 
study area have not been subjected to 
deforestation. Site 1-A experienced very little 
reduction in forest cover over this period with 
less than 0.1 percent of the cloud-free portion 
of this sub-site changing from CLOSED FOREST to 
NONFOREST area. Most of the change (four percent) 
appears as scattered individual pixels throughout 
the main body of the rain forest changing to OPEN 
FOREST. The regularity in the line spacing 
associated with seme of the pixel "scatter" may be 
attributed to radiometric distortions (striping) 
which are minimized but are not totally 
eliminated. Hence, some of the "forest change" 
should not be interpreted as change at all but 
rather as radiametrically-induced uncertainty. 
However, some of the CLOSED FOREST which changed 
to OPEN FOREST may refer to thinning of the rain 
forest. 
Land area classified as OPEN FOREST in 1973 
changed to CLOSED FOREST (3.7 percent). The 
geographic distribution of these changes suggests 
that these pixels classified as OPEN FOREST in 
1973 my have been sections of rain forest with 
small openings in the canopy (borderline CLOSED 
FOREST/OPEN FOREST classification). 
Overal 1, six percent of the area mapped as 
NONFOREST in 1973 was designated as a forest 
vegetation in 1987 thereby suggesting possible 
change from immature plantations among the 
agricultural fields to mature plantations in 1987. 
Change in Land Cover for SITE 1-B 
Site 1-B experienced the greatest amount of change 
in land cover (over 65 percent of the area). This
