Increased damage from fires in logged forests during droughts caused by El Niño

摘要: In 1997–98, fires associated with an exceptional drought caused by the El Nino/Southern Oscillation (ENSO) devastated large areas of tropical rain forests worldwide. Evidence suggests that in rainforest environments selective logging may lead to increased susceptibility fire1,2,3,4. We investigated whether this was true the Indonesian fires, largest fire disaster ever observed5,6. performed a multiscale analysis using coarse- and high-resolution optical radar satellite imagery assisted by ground aerial surveys assess extent fire-damaged area effect on vegetation East Kalimantan island Borneo. A total 5.2 ± 0.3 million hectares including 2.6 forest burned varying degrees damage. Forest primarily affected recently logged forests; primary or those long ago were less affected. These results support hypothesis positive feedback between occurrence4. The severely damaged remaining significantly risk recurrent disasters leaving huge amounts dead flammable wood.
