Habitat Overview Species belonging to this habitat require loose, sparsely vegetated, sandy soils as a primary requirement. Some are adapted to living in areas completely devoid of vegetation but the majority reside in open, sunny woodlands that have patches of bare sand interspersed with sparse ground cover and woody debris.

Many of the animal species of this habitat are burrowers, constructing either permanent tubes or capable of swimming through the sands. Others are active hunters that pursue their prey across the open barrens. The plant species are all psammophitic and xerophytic, adapted to living in sparse populations under harsh conditions, with high temperatures, little or no available water, and scarce nutrients all routinely experienced. At least one moth species, Pygarctia abdominalis, appears to be an obligate herbivore on the Spurge species found in these habitats. Another species, Elaphria cyanympha, may feed on xerophitic lichens.

This group contains species that are adapted to the driest sandy habitats in the state. Species associated with sandy river bars or other wet sandy habitats are treated separately.
