Global Change Impacts & Adaptation
Biological Indicators of Climate Change
Changes in temperature and precipitation directly and indirectly affect organisms and their habitats. Measuring these effects over time provides information on the magnitude and direction of changes in condition relevant for EPA and States’ stream bioassessment programs. Our work focuses on examining existing data to determine where and to what extent physical and biological responses to climate change can be documented. To design appropriate data collection processes to track responses, we engage EPA and State partners to conduct vulnerability assessments that identify monitoring sites, examine the capacity of current monitoring and observing networks to report on climate-related changes, and develop indicators to identify changes in water temperature, flow, and presence of coldwater organisms.
