ABSTRACT

Palaeoecology may contribute to the debate on nature conservation and the preservation of cultural heritage. Here we present two palaeo-records from the Lore Lindu Biosphere Reserve and National Park in central Sulawesi, Indonesia. The park comprises one of the largest remaining and most biodiverse mountain forests of Sulawesi. Outstanding megalithic sites reveal long-term human impact on the area. Thus, modern vegetation composition within the park has been determined by complex site histories, natural and anthropogenic. Palaeo-records from sites between 1,000 and 1,400 m a.s.l. demonstrate that human activity as well as climate variations have to be considered as the main drivers of vegetation changes in the region for the last 2,000 years. Human impact is reflected by large amounts of charred fragments in the pollen records plus low values of arboreal pollen resulting from forest clearance. The stratigraphy of one of the pollen records shows effects of a general cooling trend during the Little Ice Age (LIA). Biomass loss due to the conversion of lower montane rainforest to grassland has reduced the carbon storage potential in the area of the Lore Lindu Park. Recommendations for conservation policy that may be made from the environmental history within the biosphere reserve thus include the consideration of human influence in easily accessible areas, particularly in face of recent settlement intensification.
