White Clay Creek, Pennsylvania
Land use map of White Clay Creek watershed
In 1998, the White Clay Creek (WCC) experimental watershed, extending from the Stroud Water Research Center north to the headwaters, was designated as a site for long-term research in environmental biology (LTREB). The National Science Foundation LTREB grant to Center scientists recognizes that many important questions in ecology require the acquisition of long time series of data. NSF funds are being use to help maintain an on-going long-term research project examining stream and watershed characteristics associated with a riparian zone restoration/reforestation.
In this LTREB project, the overarching goals involve discerning the time period, most salient features, and final condition of a recovered state. LTREB funding is being used to:
- maintain existing watershed installations to continue an on-going acquisition of long-term data on White Clay Creek,
- address the data management needs of the long-term project, including making the data available to the research community, and
- test hypotheses concerning long-term variations in stream ecosystem structure and function under stable and/or recovering conditions.
Área de Conservación Guanacaste, Costa Rica
Área de Conservación Guanacaste
In 1989 the Stroud Water Research Center helped establish the Maritza Biological Station in the Guanacaste Conservation Area of Costa Rica. Located at the base of the Orosí Volcano in the northwest corner of the country, the station is the Center’s headquarters for the study of tropical ecosystems. It also serves as an information source for Latin American scientists and land managers who are interested in implementing conservation strategies in tropical streams and watersheds.
Estación Maritza is located near the banks of the Río Tempisquito, and within easy walking distance of 5 other permanent streams that are all tributaries of the Río Tempisque. These streams have been the focus of many of our studies of stream ecology and biogeochemistry. Our efforts have also extended to permanent and temporary streams near other research facilities such as Santa Rosa, Cacao, San Cristóbal, and Pitilla. Long term collection of air and water temperature, rainfall, stream discharge, seston, litter an leaf, and aquatic macroinvertebrates began at Maritza in 1990.
