Reintroduction Projects

Stephanomeria malheurensis

Known only from a single population south of Burns, Oregon, the listed endangered Malheur wire lettuce (Stephanomeria malheurensis) became extinct around 1985. The Berry Botanic Garden provided seedlings to the BLM and USFWS for what was perhaps the first plant reintroduction attempt made under the Endangered Species Act. It survived for 15 years, and because the Seed Bank holds approximately 40,000 seeds it is possible to make a second attempt, in which we are partnered with the Oregon Department of Agriculture, the BLM and USFWS.

Arabis koehleri var. koehleri

Koehler's rockcress (Arabis koehleri var. koehleri) is a candidate for state listing as threatened or endangered. Working with the Roseburg District BLM, we are augmenting an existing protected population using seed we have from the same site. We did our first majour outplanting in 2001, and are now germinating a second set of seeds for an additional planting in fall of 2007.

Calochortus umpquasensis

We are currently partnering with Umpqua National Forest to invigorate a declining population of state endangered Umpqua mariposa lily (Calochortus umpquasensis). In 2007, we placed seeds and plants grown from stored seed back in the ground at their native site.

Mirabilis macfarlanei

Brought to the atention of botanists by the Snake River boat captain for whom it is named, Macfarlane's four-o'clock (Mirabilis macfarlanei) is listed as threatened federally, and endangered by the State of Oregon. Our most recent project, in partnership with the USFS Wallowa Whitman NF, is still in the planning stages. The purpose is to establish new population of Macfarlane's in it's native Hells Canyon.


	Lilium occidentale

About half of the few known populations of the listed endangered western lily (Lilium occidentale) had been destroyed for died out when, in partnership with the Coose Bay District BLM, we began a reintroduction project in 1996. Annual monitoring has shown that plants derived from small bulbs we planted have consistently come up in greater frequency than either plants derived from new seeds (planted the year they were produced) or old seeds (having been stored in the bank for one or two years). For more information about this and the Arabis project see article by Guerrant and Kaye (2007) on Publications page.
