Legacy NPSpecies information may no longer be applicable, please remove if it is not applicable. In legacy NPSpecies Management priority value was No with comment: This still common (dominant in North Unit) native taxon could potentially decline in CRMO due to wildfire and invasion of annual weeds (rangeland conversion), and is a noteworthy vegetation resource value of the native ecosystem.
