The U.S. Fish and Wildlife Service recently completed Environmental Assessment, Rat Eradication to Promote Ecosystem Restoration on Desecheo Island, Puerto Rico. This Environmental Assessment analyzes possible consequences of five alternatives – a no-action alternative and four action alternatives – for restoring the island’s native habitat and species by eradicating non-native, invasive black rats from the Refuge. The proposed action will assist the native subtropical dry forest to recover and will promote the recolonization of the island by nesting seabirds.
