Habitat
The
Olive Vertigo is found in Newfoundland, the Northeastern USA,
and Wisconsin and
is typically found in acid sedge meadows,
shrub carr, and White Cedar swamp forests. 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)
