Loxospora assateaguensis is a crustose lichen known from a single location on the Virginian Barrier Islands of the Mid-Atlantic Coastal Plain of southeastern North America. Suitable habitat for this speciesis significantly fragmented and has been degraded by anthropogenic forces. The threats to L. assateaguensis stem from continued degradation of suitable habitat and projected impacts from sea-level rise.
This species is assessed here as Critically Endangered (CR) based on the single known location, small area of occupancy, and extent of occurrence, and the documented declines in habitat quality historically, at present, and projected into the future. It also ranks as CR based on the inferred future decline which estimates that even under the most conservative estimates, that 100% of the population, which lies at~0.3 meters above sea level (well below the 1.5 meter conservative estimate for sea-level rise by 2100; see Lendemer & Allen 2014, Sallenger et al. 2012, U.S. Army Corps of Engineers 2015) will be flooded within the next three generations as a result of sea-level rise and/or intense storm damage. It would also meet Endangered D based on the small number of mature individuals (ca.<100).
