Giant Palouse Earthworm Distribution and Habitats
Project ID: F10AC00056
Federal Agency: U.S. Fish and Wildlife Service
Partner Institution: University of Idaho
Fiscal Year: 2010
Initial Funding: $7,050
Total Funding: $24,284
Principal Investigator: Johnson-Maynard, Jodi
Agreement Technical Representative: Eames, Michelle
Abstract: This agreement is being implemented in order to gain a further understanding of the distribution and habitats of the giant Palouse earthworm, Driloleirus americanus or other Driloleirus species. The agreement will follow up on collection sites near Leavenworth, and Chelan, Washington.Potential sites near Ellensburg, WA will also be determined. Determining the site characteristics of known habitats inside and outside of the Palouse will advance understanding of the requirements of this species, and contribute to habitat modeling and potential conservation strategies. This project will benefit the Fish and Wildlife Service by advancing knowledge that will be used in the species’ status review and in future management planning on public and private land for this native species.
The Recipient shall:
• Survey sites near Leavenworth and ChelWA and determine probable locations near a known historic collection site near Ellensburg, WA.
• Surveys will be conducted using a combination of handsorting and electroshocking when soil moisture is
optimum (fall2010 and early spring 2011).
• Describe soils using standard USDA Soil Survey methods; samples will be analyzed for soil texture, pH, and soil organic matter.
• Describe vegetation conditions at each site.
• Catalog earthworms, sample for DNA and identify to species level.
• Report initial results to the Service by November 30,2010, or sooner if available, with quarterly reports thereafter.
The Fish and Wildlife Service shall:
• Provide technical assistance or staff support as needed.
• Coordinate on selection of survey sites and assist recipient in prioritizing work as needed.
• Use information provided in the giant Palouse earthworm, and potentially to guide future conservation of the Palouse and/or other bioregions in Washington.
• Cooperate with recipient on potential future research and funding activities.
