 Its sparse bunch grass, prostrate vines and low-growing shrubs are primarily a nesting, roosting, and foraging habitat for seabirds, shorebirds, and marine wildlife.Jarvis Island was once one of the largest breeding colonies in the tropical ocean, but guano mining and the introduction of rodents have ruined much of the island's native wildlife.Just eight breeding species were recorded in 1982, compared to thirteen in 1996, and fourteen species in 2004.
