Impact of Cropping Methods on Biodiversity in Coffee Agroecosystems in Sumatra, Indonesia
(2004) Gillison, Andrew N.; Liswanti, Nining; Budidarsono, Suseno; van Noordwijk, Meine; Tomich, Thomas V.
"The sustainable management of biodiversity and productivity in forested lands requires an understanding of key interactions between socioeconomic and biophysical factors and their response to environmental change. Appropriate baseline data are rarely available. As part of a broader study on biodiversity and profitability, we examined the impact of different cropping methods on biodiversity (plant species richness) along a subjectively determined land-use intensity gradient in southern Sumatra, ranging from primary and secondary forest to coffee-farming systems (simple, complex, with and without shade crops) and smallholder coffee plantings, at increasing levels of intensity. We used 24 (40 x 5 m) plots to record site physical data, including soil nutrients and soil texture together with vegetation structure, all vascular plant species, and plant functional types (PFT's readily observable, adaptive, morphological features). Biodiversity was lowest under simple, intensive, non-shaded farming systems and increased progressively through shaded and more complex agroforests to late secondary and closed-canopy forests. The most efficient single indicators of biodiversity and soil nutrient status were PFT richness and a derived measure of plant functional complexity. Vegetation structure, tree dry weight, and duration of the land-use type, to a lesser degree, were also highly correlated with biodiversity. Together with a vegetation, or V index, the close correspondence between these variables and soil nutrients suggests they are potentially useful indicators of coffee production and profitability across different farming systems. These findings provide a unique quantitative basis for a subsequent study of the nexus between biodiversity and profitability."
Rapid Ecological Assessment in Kerinci Seblat National Park Buffer Zone: Report on Plant Ecology
(1996) Gillison, Andrew N.; Liswanti, Nining; Rachman, I. Arief
"A Rapid Ecological Assessment (REA) was undertaken in two logging concessions bounding the Kerinci Seblat National Park in Central Sumatra. The REA was implemented by WWF Indonesia and funded by the World Bank. CIFOR together with LIPI advised on survey method as part of a wider study involving biodiversity assessment in the Jambi Province. An international team investigated biodiversity pattern in vascular plant species and plant functional groups, insects (mainly butterflies, moths, dung beetles and carabids), herpetofauna (amphibians and reptiles), bats, rodents, large mammals and birds. Unusually restrictive logistics reduced the number of sites to approximately half that needed for a statistical analysis. Results indicate that while plant species and functional richness vary directly with elevation, fauna show a reverse trend. The paper comments on ways of improving logging practices to conserve biodiversity. New global levels of species and functional richness were recorded for several sites. Any future baseline study will require a wider sample of land cover types."
