with those from the 1-m panchromaticly sharpened IKONOS image. A good correlation was found between the ETM+ and IKONOS -derived fc ( R 2 = 0.8) while the latter was assumed to be ground truth. In this study a modification to the linear mixture model is to use vegetation index instead of multiple reflectance bands. A great advantage of this modification is the reduced computation time, which is critical when many Landsat images are applied in basin-based studies of forest disturbances due to

forest site. Within a selectively logged area, the degree of soil compaction and modification of microclimate and biogeochemical processes varies greatly according to harvest practice. Within the studied logging sites at TNF, we stratified sampling according to decreasing damage intensity from logging decks, skid trails, felling gaps to relatively undisturbed forest ( Figure 1 ). Excluding roads where we did not sample gas fluxes, the greatest damage was found on the log storage decks (or landings
