Colonies are found in vegetation of moist, relatively well-drained lowlands, at lower elevations on mountain slopes, beach ridges where rye grass grows, and lower slopes of islands. Burrow systems often near rocky outrops and small streams (Cook and Klein 1999, Rausch and Rausch 1968). They were not found in dry lowlands or areas with much standing water (Rausch and Rausch 1968).
