Figure 6 — Average o values (dB) of 206 remnants within the 
22 first priority zones (indicated capital letters). 
The highest average o values of some fragments may 
indicate the presence of SSForest, because cerradáo's average o 
values should range around —9 dB. 
In order to achieve better results, the digital terrain 
elevation model for each fragment as well as the ephemeris of 
the satellite on the acquisition date should be considered. 
Preliminary study has already been done for Pé-de-Gigante pilot 
area but further analysis must take place later on, because a two 
ycar project is not enough to prepare all necessary data for 206 
polygons. 
The results obtained in that activity are similar to those 
obtained for savanna and tropical rainforests by Santos et al. 
(2002): campo cerrado around —13 dB; cerrado s.s. from —12 dB 
to —10 dB; cerradäo from —9 dB to —8 dB; and rainforest from — 
8 dB to —7 dB. 
4. CONCLUSIONS 
JERS-1/SAR images demonstrated to be good indicators 
of physiognomies with different aboveground wood biomass, 
such as cerrado s.s., cerraddo, and seasonal semideciduous 
forest (SSForest). 
MODIS NDVI images showed an excellent performance 
in indicating all Cerrado physiognomies. 
Because the pilot area correspond to a well preserved 
conservation unit it is acceptable the classification of the 206 
remnants located in private properties (as Legal Reserve). 
The satellite information corroborate the field observation 
that the Cerrado remnants are comprised mostly by the dense 
physiognomies of the biome. :
