Online program: From Extinction to Recovery? Reintroducing Golden Paintbrush to the Willamette Valley Dr. Tom Kaye, founder and Executive Director of the Institute for Applied Ecology, will present this topic on Zoom. Members of Emerald Chapter will receive more information on registering in our September newsletter. Last documented in the wild in Oregon in 1938, golden paintbrush (Castilleja levisecta) was apparently extirpated from Oregon through agriculture, urban development and habitat invasion by exotic weeds. Several populations remained in Washington and British Columbia, but even these have been in decline in recent years. The species was listed as Threatened by the federal government in 2000, and in 2004 became one of the first plants in the country to have a written reintroduction plan. Since 2010, the Institute for Applied Ecology has teamed with the US Fish and Wildlife Service to reintroduce this iconic prairie plant to western Oregon grasslands in an attempt to bring it back to the state, and in the process contribute to its full recovery and potential removal from the threatened species list. This process has faced many challenges, including the need to restore habitat for the species in the process and unravel its basic biology, from seed germination to its hemiparasitic relationships with host plants through root-to-root connections. This presentation will provide a tour of the history of the species in Oregon, research into its habitat relationships, and a summary of reintroduction and habitat conservation successes (and failures) in Oregon and rangewide.
