Notes: FNA23: "Before Carex kobomugi was formally recognized it was included in C. macrocephala Willdenow ex Sprengel. Carex kobomugi was collected during the early 1900s from ballast and sand near Portland, Oregon, but recent collections are not known; the habitat there may no longer exist. Clones of C. kobomugi have been registered by the U.S. Soil Conservation Service and the New Jersey Agricultural Experiment Station for long-term stabilization of coastal sand dunes. Its introduced range will likely expand."

SPNW reports it established in sand dunes in southwestern WA.
