Lacamas Prairie

This combined natural area preserve (NAP) and natural resources conservation area (NRCA) protects the best known remnant of the Willamette Valley wet prairie ecosystem in Washington. Lacamas Prairie Natural Area also protects one of the largest populations of Bradshaw’s lomatium, which is federally listed as “endangered”. The site also protects populations of five other rare plant species. The prairie remnant occurs in a native valley landscape mosaic with Oregon white oak woodland and Oregon ash wetland forest. The NAP and NRCA combined currently include 211 acres. 

 

Features Protected: Bradshaw’s lomatium, Oregon coyote-thistle, Hall’s aster, dense sedge, Nuttall’s quillwort, small-flowered trillium, Willamette Valley wet prairie, and Oregon white oak woodland
