Therefore, at this time, any sandy soils within the proposed lease parcels have to be assumed to be potential habitat for the species. The parcels listed are known to contain suitable habitat for the species, based on documented populations. *Parcels contain habitat designated as Core Conservation Areas or Conservation Agreement Areas for the species that will require additional mitigation measures if developed (USFWS 2014, SWCA 2014).
