The authority for the Service to enter into this voluntary Agreement derives from the Endangered Species Act of . 1973, as aminended, the Fish and Wildlife Act of 1956; as amended; and the Fish and Wildlife Coordination Act, as amended. - ' B. The purpose of this agreement is to formally document the intent of the parties involvedlo protect and conserve Eryngium petrolatum, Lomatium .bradshawii, and . . Trillium parviorum and their habitat on the Green Mountain Resort. . C. The objective of this agreement is to provide a for the protection and conservation ofEryngium petiolatum, Lomatium bradshawii and Trillium parviflorum and their habitat on the Green Mountain Resort D. The Management Goal is to maintain a stable or increasing population trend of Eryngium petiolatum, Lomatium bradshawii, and Trilliumparvifloruin . on the Green Mountain Resort. A decline of 35% from the baseline level for any of the populations will trigger management action if the cause of the decliners clearly indicated, or if further intensive studies determine the cause of the decline. Declines of less than 35 % were consider within the range of natural variation based on recent demographic studies(Tom Kaye, 1995.Persl.Comm.). IV. Status and distribution • Bradshaw's lomatium: Lomatium bradshawii is a federally listed endangered species,and was known until • recently as an endemic to the central and southern portions of the Willamette River Valley in western Oregon. In late May of 1994 Bradshaw's lomatium was discovered on the proposed Green Mountain Golf Course near Camas, Washington. This' new location extended the known distribution north into Clark County, Washington. Bradshaw's lomatium was first collected by IC: Nelson near Salem- Oregon in .1916. The type. specimen was collected in 1921, outside of Eugene; by R:V: Bradshaw, for whom the species was named by Mildred Mathias in 1934. Today Bradshaw's lomatium is known from Marion, Linn, Benton, and Lane Counties in Oregon and Clark County in Washington. Prior to 1994, there were a total of 52,250 plants occupying approximately 331 acres in 14 iodations. In 1994 three additional populations were discovered. The Oak Creek Conservation Easement near Sodaville in Linn County was estimated to have 200,000`plants on 56.8 acres. Two populations were found in Clark County, Washington along LaCamas Creek. The Green Mountain Resort population of about 2,500 plants occupies about 22 acres.
