San Juan, Puerto Rico


This project, prepared for the Conservation Trust of Puerto Rico (the Trust), outlines the initial development of an Index of Biotic Integrity (IBI) for the San Juan metropolitan area of Puerto Rico. It adapts methodologies developed in rural areas of the mainland United States to the tropical urban streams in San Juan and recommends updates to the Trust's Mapa de Vida stream assessment protocols. Stream flow data, water quality data, and macroinvertebrate samples were collected at nine sites in a set of six streams representing a gradient of environmental quality throughout the San Juan area to form a data set on biological communities of urban streams. Statistical data analysis supported recommendations for eight indices that comprise an IBI for the streams of San Juan.
