Habitat
Preferred habitats include dune and grass-umbel communities and secondarily, forb and mixed (grass-umbel and forb) habitats. Carex and upland habitats do not appear to be used by the shrews (Byrd and Norvell 1988). Most abundant in habitats with greater tall stems per unit area (Byrd and Norvell 1988, Byrd and Mendenhall 1986). Found at high densities within communities dominated by tall plants, particularly beach rye (Elymus arenarius), bluegrass (Poa eminens), wild celery (Angelica lucida), and sage (Artemesia arctica; Byrd and Norvell 1993).
