Camassia quamash Lowland Wet Prairie | NatureServe Biotics 2019

Name: Camassia quamash Lowland Wet Prairie Reference: NatureServe Biotics 2019 Description: Habitat is clay prairie and basalt scabland with a seasonally perched water table. <i>Camassia quamash</i> is the primary species in this association, with lesser amounts of <i>Saxifraga oregana, Ranunculus occidentalis</i>, and <i>Triteleia hyacinthina</i>. <i>Camassia</i> is conspicuous in spring and forms dense stands of gorgeous blue flowers, but it all but disappears with summer drought. Because of its seasonal presence, low elevation, and proximity to agriculture, many exotic species are present. Weeds such as <i>Hypochaeris radicata, Stellaria, Aira caryophyllea</i>, and <i>Galium aparine</i> may be inconspicuous when <i>Camassia</i> is at its peak but may dominate sites once it has disappeared. Both white and blue forms of <i>Camassia quamash</i> may be present, as well as <i>Camassia leichtlinii</i>. Camas was one of the most important staple foods for the original native peoples of the Willamette Valley, and wet prairies were intensively managed for food production. Arable prairies were converted to agriculture, and those on scabland sites were grazed by livestock, so that most surviving remnants are degraded with exotic species. This association may intergrade with the <i>Triteleia hyacinthina</i> association in areas of shallow soil over bedrock that have a perched water table or seasonal seepage.  Accession Code: urn:lsid:vegbank.org:commConcept:32223-{F2E28D6F-D1E1-4E3E-B64B-D84675D0FCEA} Plot-observations of this Community Concept: 0
