Climate change in headwater streams - a baseline for monitoring and assessment
In order to provide a baseline for climate change among coldwater streams we located 100 m sampling reaches on 20 Laurel Hill sites previously surveyed by Sharpe et al. (1987) in 1983. During April 2011, we installed in-stream and riparian zone temperature monitors in three northwest (NW) and three southeast (SE) facing paired watersheds. In addition, monitors were installed in Laurel Hill and Loyalhanna creeks – major coolwater receiving streams along each slope.
During May and June, 2011 fish populations were sampled along the 100 m reach of each stream by back-pack electrofishing. Sampling stations were located as close as practicable to the locations surveyed by Sharpe et al. (1987), however, due to access limitations Roaring Run North was replaced by Allwine Creek. All fish were identified, measured, and enumerated in the field. Four voucher specimens were retained and the remainder released. Specific conductance (μS/cm), pH, and in-stream temperature (oC) were recorded on- site and a sample collected and analyzed for total alkalinity (mg/l as CaCO3) in the laboratory at California University of Pennsylvania. All sites were georeferenced.
