Habitat and Ecology [top]

Habitat and Ecology:This fossorial Boa was found in the palm groves of mid-altitude top-soil layers on volcanic slopes.

Threats [top]

Major Threat(s): The introduction of rabbits and goats to the island in 1840 resulted in damage to the vegetation, consequently causing soil erosion on the volcanic slopes and deterioration of palm forest habitat. This decline in habitat quality is thought to have been the main reason for the extinction of the Round Island Burrowing Boa.
