ODF finishes gathering Oregon ash seeds

Oregon Department of Forestry staff recently completed its effort to collect seeds from Oregon ash (Fraxinus latifolia) trees throughout the Oregon portion of the species range, before they are wiped out by an invasive pest.

Between 2019 and the end of 2022, five ODF staff members collected more than 900,000 seeds from 245 mother trees representing 27 distinct populations from the Coast Range throughout the Willamette Valley and the western Cascade foothills, and south to the California border.

The collecting effort was made possible by a federal grant from the USDA Forest Service. The collected ash seeds were cleaned and sorted at ODF’s JE Schroeder Seed Orchard facility in St. Paul. 

A third of the seeds were sent to the primary long-term storage facility at the Center for Agricultural Resources Research (ARS) National Seed Lab in Fort Collins, Colorado. Equal amounts were also sent to the USDA Forest Service’s Dorena Genetic Resource Center in Cottage Grove and to the USDA Agricultural Research Service’s North Central Regional Plant Introduction Station in Ames, Iowa. 

This will allow both sites to help facilitate research on Oregon ash, the only species of ash native to the state.
