Summary
ABSTRACT
Monteverde, Costa Rica is home to a tropical montane cloud forest that illustrates the balances between habitat and development inherent to ecotourism. The Monteverde Cloud Forest Reserve, located on the leeward side of the Continental Divide, has experienced a 100-fold increase in visitors since its inception 20 years ago. The associated growth in population and commercial development has the potential to impact water resources. Over three years, more than 400 stream-water samples were collected from eight sites above and below the main road within the Rio Guacimal watershed to assess the effect of development on water quality. The chemistry of upstream samples reflects mineral weathering and cation exchange reactions in the forest soils. Comparisons of downstream samples to these baseline data showed evidence of anthropogenic impacts: chemical concentrations were two to five times higher at downstream locations. The highest concentrations were observed at the site with the highest population density. These results point to the value of forest preserves, specifically the Monteverde Cloud Forest Reserve and the Bosque Eterno de Los Niños (or the Children's Eternal Rainforest), in limiting growth in riparian areas, which in turn helps to protect the quality of water resources for downstream communities.
