Facts About

First reported in west-central Idaho in 1969, common crupina has spread rapidly in western rangelands, where it is avoided by cattle and forms monospecific stands in grazed lands. It is invasive in The Northwest and California, and has been recorded from Massachusetts.

Anthropogenic (man-made or disturbed habitats), meadows and fields
