Hypotrachyna virginica warrants a status of critically endangered as its AOO and EOO are projected to reduce by >80% within its next three generations. Species distribution models projected to 2050 and 2070 using two different climate change models (CCSM4 and HadGEM2-AO) at the lowest and highest carbon dioxide concentration (2.6 and 8.5 rcp) were recently built in Maxent for this species (Allen & Lendemer, 2016). The results of the modeling predict an average suitable habitat loss of 94.3% with aminimum loss of 83.4% and a maximum loss of 100%. This represents a significant decrease in the AOO and EOO for the species.
