摘要: In this study, we used over 50 high-resolution satellite images to analyse sequences and interrelations in the progression of peatland degradation conversion processes Sumatra, Indonesia. Changes were monitored three study areas 2,500–3,500 km2 since 1970s examined conjunction with satellite-based active fire data sets. Forests disturbed by intensive logging noticed be intermediate stages towards further degradation. Fires practically non-existent nearly pristine peat swamp forests (7 fires/100 km2, 1996–2010), but highly concentrated heavily degraded forest (140 km2) leading either an extremely landscape or agriculture. The results highlight vulnerability ecosystems indicate that most remaining forested peatlands Sumatra are danger being fully converted agriculture turning into unmanaged wastelands under current management practices.
