Cyperus grayioides is fairly abundant where it occurs, in open areas of deep, disturbed sands. It is restricted to areas with periodic disturbance by fire, wind, and/or erosion, however, and is vulnerable to encroachment by woody or weedy plant species. Sand prairie habitats have declined severely as a result of agricultural and residential development, fire suppression, and grazing. Many populations of C. grayioides occur on public lands, in which fires and natural soil disturbances are more likely to occur; in Missouri, however, all populations of this species currently occur on private lands.

C. grayoides is found in 6 counties in Illinois, 3 counties (with 4 populations) in Missouri, 21 counties in Texas, 4 parishes in Louisiana, and 4 sites in the National Texas Forest.
Restoration suitable habitat in several national forests in Texas is currently underway after severe storm damage that occurred in 1998. (Turner 1999)
The Illinois DNR Division of Natural Heritage is monitoring a population located in a nature preserve in Mason County. (IL DNR 2002)
