Natural resources:

terrestrial and aquatic wildlife

Land use:

arable land: 0%
permanent crops: 0%
other: 100% (2008)

Natural hazards:

Baker, Howland, and Jarvis Islands: the narrow fringing reef
surrounding the island can be a maritime hazard
Kingman Reef: wet or awash most of the time, maximum elevation of
less than 2 m makes Kingman Reef a maritime hazard
Midway Islands, Johnston, and Palmyra Atolls: NA

Environment - current issues:

Baker, Howland, and Jarvis Islands, and Johnston Atoll: no natural
fresh water resources
Kingman Reef: none
Midway Islands and Palmyra Atoll: NA

Geography - note:

Baker, Howland, and Jarvis Islands: scattered vegetation consisting
of grasses, prostrate vines, and low growing shrubs; primarily a
nesting, roosting, and foraging habitat for seabirds, shorebirds,
and marine wildlife; closed to the public
Johnston Atoll: Johnston Island and Sand Island are natural islands,
which have been expanded by coral dredging; North Island (Akau) and
East Island (Hikina) are manmade islands formed from coral dredging;
the egg-shaped reef is 34 km in circumference; closed to the public
Kingman Reef: barren coral atoll with deep interior lagoon; closed
to the public
Midway Islands: a coral atoll managed as a national wildlife refuge
and open to the public for wildlife-related recreation in the form
of wildlife observation and photography
Palmyra Atoll: the high rainfall and resulting lush vegetation make
the environment of this atoll unique among the US Pacific Island
territories; supports a large undisturbed stand of Pisonia beach
forest
