Freshwater Snail Inventory at Upper Delaware Scenic and Recreational River - Spatial Data - Dataset As Delivered

Description

Species Inventory project as-delivered dataset, geopackages and associated geospatial files The Upper Delaware Scenic and Recreational River (UPDE) unit of the National Park Service partnered with the Academy of Natural Sciences of Drexel University (ANS) to perform a freshwater snail inventory within the park. ANS and UPDE teams conducted field research in July and August of 2022 and 2023 using a combination of kick sampling and hand-picking methods to determine the abundance and diversity of freshwater snail populations. Fifty-four sites were chosen along the ~70 miles of the Delaware River within UPDE and included coldwater and warmwater fisheries zones. In 2022, field collections occurred at 30 sites along the river edge from Hancock, NY to the No. 2 railroad bridge near Mill Rift, PA. In 2023, field work occurred at 24 sites in more disturbed areas like river access points and boat launches, and within habitats that were not sampled in 2022 (i.e., backwater, channels, and islands). Snails were identified using traditional morphological taxonomy and DNA barcoding of the CO1 (Cytochrome c oxidase I) gene. Additional environmental DNA (eDNA) was analyzed from water collected at ten eDNA Atlas Sites. This study identified 27 taxa of snails, one of which is a non-native species, the Japanese Mystery Snail (Cipangopaludina japonica). A better understanding of the snail community and the ecosystem has been gained with the results of this inventory which will inform effective and responsible river management plans.
