Bulimulus saeronius is endemic to Santa Cruz Island in the Galápagos Islands. It was not found alive over the past three years of collecting on Santa Cruz Island. It may already be extinct, however, further surveys are required to confirm this. Suitable range area for this species has declined because of human activities (mostly farming). There is now likely to be less than 100 km² of habitat left. Habitat destruction and alteration by human activities and introduced species are the main threats to the species.

Major Threat(s): Habitat destruction and alteration by human activities and introduced species. The introduction of fire ants to the area is thought to form the main threat to this species. The invasive little fire ant, Wasmannia auropunctata, occurs on the island (Roque and Causton 1999).
