'''''Carex inops''''' is a species of sedge known as '''long-stolon sedge'''<ref name=usda>{{PLANTS|id=CAIN9|taxon=Carex inops|accessdate=2018-11-20}}</ref> and '''western oak sedge'''.<ref name=fotcr2017>{{cite book|last1=Wilhelm|first1=Gerould|last2=Rericha|first2=Laura|date=2017|title=Flora of the Chicago Region: A Floristic and Ecological Synthesis|publisher=Indiana Academy of Sciences}}</ref> It is native to northern North America, where it occurs throughout the southern half of Canada and the western and central United States.
There are two subspecies; ''Carex inops'' subsp. ''inops'' is limited to the west coast from British Columbia to California, while ''Carex inops'' subsp. ''heliophila'' ('''sun sedge'''), is more widespread and is more common east of the Rocky Mountains.<ref name=feis>Fryer, Janet L. 2009.

==Description== This sedge produces a loose clump of stems up to 50 centimeters tall. The stiff, narrow leaves persist, with dead ones remaining around the base of the plant. The inflorescence usually has pistillate spikes below staminate spikes.<ref name=fna>[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242357255 ''Carex inops''.] Flora of North America.</ref> The plant grows from rhizomes and fibrous roots; despite its common name, it does not usually form stolons.<ref name=feis/>
==Ecology== This plant, particularly sun sedge (''C. inops'' subsp. ''heliophila''), is a dominant species in a number of ecosystems, such as many grasslands. On the prairies of the northern Great Plains it is codominant with grasses such as western wheatgrass (''Pascopyrum smithii'') and other wheatgrasses, big bluestem (''Andropogon gerardi'') and other bluestems, needle-and-thread grass (''Hesperostipa comata'') and other needlegrasses, and/or blue grama (''Bouteloua gracilis'') and other gramas. It is common on the tallgrass prairies of Kansas alongside bluestems and prairie sandreed (''Calamovilfa longifolia''). It can be a dominant species in Rocky Mountain meadows, woodlands in Nebraska, the Black Hills of South Dakota and Wyoming, and the plains of Saskatchewan. It can be found in each stage of ecological succession on grasslands. It can colonize blowouts, anthills, and prairie dog towns.<ref name=feis/>
Many types of animals consume this plant, particularly ''C. inops'' subsp. ''heliophila''. It is considered a good forage for livestock because it is one of the first green plants to appear in the spring and animals such as cattle find it palatable.<ref name=feis/>
