Executive Summary

Lomatium cookii is endemic to southwestern Oregon with only two known populations in Jackson and Josephine Counties. The species is listed as endangered by the State of Oregon and the U.S. Fish and Wildlife Service, and the Draft Recovery Plan for the species identifies population augmentation and reintroduction as necessary steps toward recovery. Reintroduction through direct seeding and transplanting in experimental plots occurred in the Illinois and Rouge River Valleys at French Flat, Agate Desert, and Reeve’s Creek in 2006, 2007, and 2009. This report updates the status of these reintroduction plots, which we annually monitored at French Flat (South and North) as of 2017, at Agate Desert as of 2011, and at Reeve’s Creek as of 2017.
