Alsophis antiguae has been assessed as Critically Endangered. This species distribution across Antigua and Barbuda has historically been reduced to a single population on Great Bird Island. Since 1995, the Antiguan Racer Conservation Project has led a reintroduction programme, and there are now populations on Rabbit, Green, and York islands, with the global population exceeding 300. However, the species extent of occurrence is only 0.65 km² (less than 0.1% of its natural range) and it is continually threatened by invasive species, inbreeding depression, and natural disasters. Continued conservation management, population monitoring and invasive species control are needed to guarantee the species persistence.
