How Coffee Affects Biodiversity
A 2003 graduate of CERC’s Executive Education Program in Conservation and Sustainability and doctoral student at the University of Rhode Island, S. Amanda Caudill writes for NY Times Scientist at Work, where she is assessing biodiversity on coffee farms in Costa Rica.
Drawing upon previous field research in the Coorg region of southwest India, S. Amanda Caudill is currently evaluating mammal biodiversity in coffee dominated regions in Turrialba, Costa Rica. Her findings will help determine which habitat parameters are important to the mammals and shape suggestions on how to enhance the habitat, in part through recommendations of sustainable farming practices.
S. Amanda Caudill notes that coffee is the second most traded commodity in the world, acting as the primary export for many developing countries. Though coffee was traditionally grown in native forests, it has become increasingly common to replace the diverse ecosystem with a monoculture of coffee plants. This change has profound effects on the species richness and abundance that the landscape can support and the environmental services that can be provided, including soil erosion, pollination, and water clarification.
Though researchers have explored the impact of developing these coffee habitats on birds and insects, the affect on mammals remains largely unknown, placing S. Amanda Caudill’s research at the forefront of conservation.
S. Amanda Caudill and her field assistants use small and large traps and track plates and camera traps to directly and indirectly survey animals in the region, respectively. She notes that the logistics are relatively straightforward, but challenges often emerge, as the equipment can be difficult to find in the field and liable to be stolen by thieves. Additionally, using machetes to cut trails and set up trap locations is extremely dangerous, resulting in serious injuries if necessary precautions aren’t taken.
