In the absence of population control, feral goats rapidly assume ecological dominance in island ecosystems. There, they are implicated in habitat destruction, alteration of species composition (including extinctions), and altered ecosystem processes and functions. We have demonstrated that removal of goats can lead to the rapid recovery of suppressed vegetation, and have been instrumental in goat eradications from several islands around the world including San Clemente Island, California, Aldabra Atoll in the Seychelles, and Isla Santiago and Isla Isabela in the Galapagos.
Did you know? Goats removed forage to the height they could reach and greatly reduced shade for tortoises. This is bad news for tortoises, as being deprived of shade on Aldabra will likely kill them quickly.
