Rich floodplain forests and forested slopes of larger streams; sometimes in thickets and forest edges, often along trails. This species is known from the Clinton, Grand, Raisin, Rouge, and St. Joseph River systems.
Though known in Michigan since the late 1800's Carex davisii was rarely collected until nearly a century later, when numerous stations started to turn up, especially along the Grand River system. Perhaps it has been increasing its range in the state recently.
