Stream Fish Monitoring Data in Eastern Rivers and Mountains Network Parks (2022-2023) Data Package

This data package contains fish community and habitat data collected at 69, 100-meter-long reaches in wadeable streams throughout six national park units in the Mid-Atlantic Region. To account for imperfect detection and to estimate fish species occupancy and detection probabilities, reaches were sampled using pulsed DC backpack electrofishing, typically on three independent occasions in a single season (i.e., 2022 or 2023), with as few days as logistically possible between visits. All captured fish were counted and identified to species before releasing them throughout the sampled reach. At least one representative of each species, sex (when distinguishable), and age class (i.e., young-of-year, adult) were photographed. In-stream and riparian habitat were characterized, including basic water quality (e.g., pH, specific conductance), discharge, substrate size and embeddedness, channel morphology, fish cover, riparian vegetation type and cover, and human disturbance.
