Table 1 Forest degradation activities and their degree of detection using Landsat-type data, adapted from [44].

From: Options for monitoring and estimating historical carbon emissions from forest degradation in the context of REDD+

Highly Detectable Detection limited & increasing data/effort Detection very limited
• Deforestation • Forest fragmentation • Recent slash-and-burn agriculture • Major canopy fires • Major roads • Conversion to tree monoculture • Hydroelectric dams and other forms of flood disturbances • Large-scale mining • Selective logging • Forest surface fires • A range of edge-effects • Oldslash-and-burn agriculture • Small scale mining • Unpaved secondary roads (6-20 m wide) • Selective thinning of canopy trees • Harvesting of most non-timber plants products • Low-mechanized selective logging • Narrow roads (< 6 m wide) • Understory thinning and clear cutting • Invasion of exotic species
