Bradshaw's lomatium <br /> Species Description <br /> L. bradshawii is a member of the Apiaceae =U ■-lliferae, parsley or <br /> umbel) family (USFWS 1993). It is a t - pr• , herbaceous plant with <br /> compact yellow flowers in compound u s . ^r chcoc and Cronquist 1973, <br /> Kagan 1980) . It is found in season fly ,; t � "° T �: s of the Willamette <br /> Valley in Marion, Benton, Linn, and ,:.; Count. More detailed <br /> descriptions of L. bradshawii can be •d in Hitchcock and Cronquist <br /> (1973), Kagan (1980), Meinke (1982) ani Lomatium Recovery <br /> Plan (USFWS 1993) (Recovery Plan " <br /> Habitat <br /> L. bradshawii is endemic�, � th e ral and southern portions of the <br /> Willamette Valley n.wefiter 0 =gbn ( USFWS 1993). According to the <br /> Recovery Plan (US L1993.it is known to occur in two distinct habitat <br /> fr -` <br /> types: (1) shallow alluvi1. soils near the Santiam River; and (2) <br /> seasonally saturated o flooded prairies along creeks and streams in the <br /> southern Willamete Val l ey. The latter habitat is more common and <br /> supports more +.pulatioris than the former. In addition, a large <br /> population wa , ecen _y discovered near LaCamas Lake, Washington in <br /> 1994. ;, <br /> L. bradshawii occurs in the wet prairies dominated by tufted - hairgrass <br /> ( Deschampsia caespitosa). The Deschampsia community is a tall grass <br /> prairie type, typically found in the low, flat, bottomlands of the <br /> Willamette Valley (Franklin and Dyrness 1973). These areas usually <br /> have standing water from October to May. The soils are uniformly heavy <br /> clay with little rock, sand, or gravel present (Kagan 1980). <br /> Native vascular plants associated with this habitat type are listed in <br /> Appendix 1. Many introduced plants are also common in the wet prairie <br /> habitat. Common introduced species found at Willow Creek Preserve, a <br /> Deschampsia caespitosa grassland in west Eugene, are also listed in <br /> Appendix 1. The wetter depressions often support Hordeum brachyantherum <br /> (meadow barley), Beckmannia syzigachne (American sloughgrass), <br /> Alopecurus geniculatus (water foxtail), Camassia quamash (common camas), <br /> Montia linearis (narrow - leaved montia), and Eleocharis acicularis <br /> (needle spike -rush) (Franklin and Dyrness 1973). <br />
