Amphibian Inventory for Ebey's Landing National Historical Reserve tabular data

Amphibian survey for Ebey's Landing National Historical Reserve, 2002-2003

Our primary goal was to meet the National Park Service Inventory and Monitoring program goal to better assess the status of amphibian species listed as “expected” in the parks and to verify the occurrence of 90% of these species. Our primary goal for EBLA was to search for the presence of expected amphibian species: Ensatina; western red-backed salamander; northern red-legged frog; Oregon spotted frog; American bullfrog; Pacific treefrog; western toad; northwestern salamander; long-toed salamander; and rough-skinned newt. Inventories of reptiles were not targeted during this project; however they were documented when encountered.

Nineteen aquatic and 15 terrestrial surveys were conducted in 2002 and 2003. A total area of 75,286 m2 was searched in 4,013 minutes, over 14 days. During the surveys, for each species encountered, information on species life stage and habitat, was documented.

Species names have been verified and updated as needed based on Crother (2008). Species absence is extremely difficult to determine and it is possible that some species recorded historically or occasionally but not detected during our survey efforts may still be present in the park. Additional surveys of targeted habitats and species should be conducted.

This project at Fort Vancouver National Historic Site (FOVA) and the greater Vancouver National Historic Reserve was part of a larger effort to document species presence at five North Coast and Cascades Network parks: Mount Rainier National Park, Ebey’s Landing National Historical Reserve (EBLA), Lewis and Clark National Historical Site (LEWI, formerly FOCL), FOVA, and San Juan Island National Historical Park (SAJH). Four parks (EBLA, FOCL, FOVA, and SAJH) had incomplete amphibian lists based on limited or undocumented data.
