Phenology: "The study of periodic plant and animal life cycle events and how these are influenced by seasonal and interannual variations in climate" - Wikipedia.
Trout Unlimited is collaborating with the University of Massachusetts and several other partners to develop a community science program that examines impacts of climate change on the phenology of trout streams and their riparian areas. Anglers will record observations of temperature, streamflow, and seasonal aquatic insect, fish and riparian plants. The resulting records will yield a database of ecosystem health, allowing us to develop "fishability" indices and incorporate this into TU climate change outreach campaigns at the chapter, council and national levels.
We are also looking for older angling records to compare with data the anglers will collect. We need your help determining the degree to which such records have been kept. Please take a few minutes to fill out the following survey. The results of the survey will help us determine what type of information might be available for different river systems around the country. At this point, please do not send in any specific angling records.
