Conservation

Lacamas Prairie Natural Resources Conservation Area/Natural Area was first established in 2007 following land acquisition by Washington Department of Natural Resources, who continues to administer the combined units. DNR aims to conserve the total of prairie in the area. In addition to the DNR owned lands, are owned and protected by Clark County, and an additional are owned by Columbia Land Trust. The remaining land is privately owned. Between 2019 and 2021, DNR was granted $6.3 million by the state of Washington for the purposes of land acquisition and stewardship for Lacamas Prairie.
DNR periodically performs prescribed burns to maintain the prairie ecosystem and reduce populations of invasive species.

The prairie is home to one of the largest known populations of the endangered Bradshaw's lomatium. It is the location of one of only five known populations of tall western penstemon, and represents the sole population in Washington. Other sensitive species of the prairie include Oregon coyote-thistle, Hall's aster, dense sedge, Nuttall's quillwort, and small-flowered trillium.
