Bulimulus darwini is endemic to Santiago Island in the Galápagos. Five subpopulations are known on the island and total range area is likely to be less than 2,000 km². The species is found throughout the humid zone on Santiago Island.
It was reduced to a few small populations in 1970’s because of habitat destruction by feral goats, pigs and donkeys. However, the wild pigs were exterminated from this island in 2001, and goats and donkeys are being exterminated at the moment, so Santiago should no longer have goats or donkeys in a few years from now. The vegetation on the island now has started to grow back and the land snail populations are now larger and more numerous. However, it seems that this species is highly influenced by El Niño events with subpopulation sizes fluctuating from year to year.
