Avondale, PA This February, scientists at the Pennsylvania-based Stroud Water Research Center take the world stage once again with another groundbreaking study on the Center's focusfresh water. This new study, made possible with a Long-Term Research in Environmental Biology (LTREB) grant from the National Science Foundation (NSF), will investigate how the ecology of a stream changes as trees planted along the stream banks mature.
Grant funding will allow Stroud Water Research Center scientists to build on over 40 years of data and use cutting-edge technologies to collect new data on everything from the shape of the stream channel of southeastern Pennsylvania's White Clay Creek (WCC) to the food resources of the insects and fish living in the stream.
"The grant represents the combined efforts of all research fields at the Center and builds on the collaborative science that is a hallmark of our organization," said Dr. Louis A. Kaplan, senior research scientist at Stroud Water Research Center and the grant's project director.
Restoration of the stream began in 1967 when Stroud Water Research Center was established in a pasture next to WCC and cattle that had been trampling the stream banks were removed. The Center began a complete restoration and reforestation of the riparian zone in the mid-1980s with the planting of native deciduous trees and removal of invasive plant species. As the forest has grown, Center scientists used prior LTREB funding to characterize the sequence of changes in the physical, chemical, and biological attributes of the stream; this new grant will extend those studies as the forest matures.
"We have known for years that the reforestation of stream banks is perhaps the single most important step that can be taken to improve water quality and stream health," said Kaplan. "What we do not know is the sequence of events or time frames needed to reach certain milestones along a stream restoration trajectory.
