ERMN Monitoring Stream Fish (2022-2023)

Tzilkowski C and Stum M. ERMN Monitoring Stream Fish (2022-2023). 2022-2023. Eastern Rivers and Mountains Network, National Park Service

In collaboration with the U.S. Geological Survey (Pennsylvania Cooperative Fish and Wildlife Research Unit) and The Pennsylvania State University, the Eastern Rivers and Mountains Network surveyed fish communities in wadeable streams throughout six National Park Service units during 2022 and 2023. Repeat assessments using the same approach are planned to be conducted at least once per decade to: (1) quantify changes in fish species occupancy and (2) investigate site- and watershed-scale habitat factors that affect estimates of species occupancy and detection probabilities. Reaches were backpack electrofished in a single pass, on three occasions within as few days as possible. Sampling was conducted by a crew of 3 – 7 people using pulsed DC and block nets. Reach- and watershed-scale habitat were characterized to investigate drivers of species detection and occupancy estimates. This information will provide warning signs of native species decline, or an increase in non-native species, and will aid in developing proactive management strategies to protect and restore critical aquatic habitat in parks.
