Bradshaw's Lomatium (Lomatium bradshawii) 


Bradshaw’s lomatium (Lomatium bradshawii) is a Federal and State protected Endangered Species.  A recovery plan was completed in 1993 (USFWS, 2010).  The USFWS finalized a multi-species recovery plan for listed plants in the Willamette valley, including Bradshaw’s lomatium in 2010 (USFWS, 2010).

Bradshaw’s lomatium is a perennial wildflower found in seasonally flooded wetland prairies of the Willamette Valley.  A L. bradshawii subpopulation is being managed at the Short Mountain Landfill property. This population is annually monitored and tracked with Geosptial Survey in conjunction with the US  Fish and Wildlife Service.  Associated native species include tufted hairgrass (Deschampsia cespitosa), meadow barley (Hordeum brachyantherum), dense sedge (Carex densa), camas (Camassia quamash), death camas (Zigadenus venenosus), northwest cinquefoil (Potentilla gracilis), and meadow checkermallow (Sidalcea campestris).  In 2007 when Phase V of Short Mountain Landfill was constructed, small clusters of L. bradshawii were transplanted to portions of the property that would not be impacted in the future. This slideshow shows the transplant process.
