- Selah Cliffs Natural Area Preserve (NAP) was established in 1993 to protect the largest known population of basalt daisy (Erigeron basalticus), a state-listed threatened species known from only a 10-mile stretch of the Yakima River Canyon. The basalt daisy makes its home on the basalt cliffs of the site where few other plants can grow, rooting into cracks and fissures on the rock faces. The daisies are typically in bloom May through October, with a peak in June. The cliffs, much of which are covered by colorful lichens, also provide nesting and roosting habitat for raptors including prairie falcons (Falco mexicanus), red-tailed hawks (Buteo jamaicensis) and kestrels (Falco sparverius).

This 957-acre site protects a montane herbaceous bald ecosystem that supports two additional rare ecological features identified in the Washington State Natural Heritage Plan: the Roemer’s fescue-field chickweed-Junegrass community and the common bluecup plant (which actually is not very common in Washington State).
