In 1835, Charles Darwin was the last person to officially see a land iguana on Santiago Island in the Galapagos. After that encounter, predators like the feral pig wiped the lizard population out of that location. Now — nearly two centuries later — an initiative by the Galapagos National Park authority has reintroduced more than 1,400 land iguanas (Conolophus subcristatus) back to Santiago Island. Authorities said in a recent statement that on January 3 and 4, the land iguanas were taken from neighboring North Seymour Island and introduced to the coastal regions Puerto Nuevo and Bucanero, which have similar ecosystems to the iguanas’ former home. The Galapagos Conservation Trust says that the archipelago’s land iguana population suffered when species like cats, rats, dogs and pigs were introduced.
