It is also found in acidic deciduous forest composed of Red Maple, northern White Cedar, and Atlantic white ceder. This species has been found to be a consistent component of sedge meadow and wooded wetland sites throughout eastern Massachusetts, Connecticut, southeastern New Hampshire and southern Maine. Populations are now also known to extend as far west as North central Wisconsin. Vertigo perryi can become quite abundant in sedge meadows in coastal New England, where thousands of individuals may occur per square meter. (Nekola 2011)
