Hawaii has the greatest number of endangered species in the Nation. WS protects these species, including endangered waterbirds at State sanctuaries and wetland sites on military installations, from introduced predators such as the small Indian mongoose. When feral goats, sheep, pigs, and deer impact threatened and endangered plants, and public hunting is not feasible, WS works closely with State, Federal, and private organizations to removal animals that are causing damage and negatively impacting native species.
