Terrestrial invertebrate abundance in the Elwha River estuary, Washington, in 2007 and 2013.

Metadata Updated: November 12, 2020

This portion of the data release presents terrestrial invertebrate abundance data from samples collected in emergent and shrub vegetation along the edge of the Elwha River estuary, Washington, in 2007 and 2013 (no associated USGS Field Activities numbers because data were collected predominantly by biologists from the Lower Elwha Klallam Tribe). We deployed terrestrial insect fallout traps at ten locations in the east estuary, five replicates each in shrub and emergent (littoral) vegetation habitats. Clear, rectangular traps (2,400 cm2 in 2007 and 3,526 cm2 in 2013) were filled with 5 cm of filtered soapy water and deployed for 72 hours. Invertebrate counts from 2013 were standardized to the 2007 bin size to account for the different area of the fallout traps between years. Samples were filtered through a funnel sieve and stored in 70 percent ethanol until processing. Invertebrates were identified to genera when possible. However, taxonomic resolution was not consistent across species so we grouped data by Order for our analyses (unless otherwise noted in the attributes). The locations of samples were determined with a hand-held global positioning system (GPS). Terrestrial invertebrate abundance data are provided in a comma-delimited spreadsheet (.csv).
