Papahānaumokuākea Marine National Monument is the single largest conservation
area under the U.S. flag, and one of the largest marine conservation areas in
the world. Extensive coral reefs can be found below the water surface, housing
over 7,000 marine species. Many of the islands and shallow water environments
are vital habitats for species such as the threatened green turtle and the
endangered Hawaiian monk seal. Land areas also provide a home for unique bird
species, including the world's most endangered duck, the Laysan duck. In
addition to the importance to marine wildlife, this sanctuary has significant
cultural importance to Native Hawaiians. Visitors can enjoy this cultural and
marine conservation site with activities such as snorkeling, diving, and
interactive educational exhibits in the visitor center. To learn more about
this sanctuary, visitors should stop by the Mokupāpapa Discovery Center.

Hakalau Forest NWR contains some of the finest remaining stands of native
montane rain forest in Hawai‘i. The slopes below 4,000 feet receive very high
rainfall - 250 inches annually. Bogs, fern patches, and scrubby forest
dominate this area which is dissected by numerous deep gulches. Rainfall
decreases to about 150 inches at elevations above 4,500 feet, where majestic
koa and red-blossomed ‘ōhi‘a trees form a closed-canopy forest. Further
upslope, above 6,000 feet, rainfall decreases to 100 inches or less and native
forest merges into abandoned pastureland where alien grasses and weeds,
introduced as forage for cattle, are the dominant vegetation. Since 1989, over
400,000 koa, ‘ōhi‘a, and other native plants have been planted in this area as
part of the refuge's reforestation program.

In 1997, the U.S. Fish and Wildlife Service purchased approximately 5,300
acres of land to create the Kona Forest Unit of Hakalau Forest NWR. The Kona
Forest Unit includes lands within the Ho‘okena and Kalahiki land divisions on
the western slopes of Mauna Loa, at elevations between 2,000 and 6,000 feet.
Kona Forest Unit is located approximately 23 miles south of Kailua-Kona.

At the lower elevations - 2,000 to 3,600 feet - the forest is predominately
‘ōhi‘a trees with an understory of nonnative trees and shrubs, such as
christmasberry, clidemia, an strawberry guava. Above 3,600 feet, the invasive
trees and shrubs drop out and the forest is dominated by ‘ōhi‘a and koa trees
with an understory of ferns and native flora. A remnant of dry ‘ōhi‘a forest
is found at the highest elevations and includes sandalwood and māmane.

The primary purpose for establishing the Kona Forest Unit is to protect,
conserve, and manage this native forest for threatened or endangered species.
Of particular concern was the ‘alalā (_Corvus hawaiiensis_), whose wild
population, known only from the west side of the Big Island, gradually
declined to only a single pair in 2002. After 1993, the wild population of
‘alalā was observed intensively, as the number of birds gradually declined to
a single pair in 2002, and were not seen after June of that year. As of 2008,
approximately 50 ‘alalā are in captivity at the Keauhou and Maui Bird
Conservation Centers on Hawai‘i and Maui islands, respectively. Once the Kona
Forest Unit is fenced, feral ungulates removed, and vegetation and habitat
restored, progeny from these captive birds may be released into the Kona
Forest Unit.

The Kona Forest Unit also offers protected areas for other endangered species,
including the Hawai‘i ‘ākepa, (_Loxops coccineus_), Hawai‘i creeper
(_Oreomystis mana_), ‘akiapōlā‘au (_Hemignathus munroi_), ‘io (Hawaiian hawk),
and ‘ōpe‘ape‘a (Hawaiian hoary bat), as well as, several endangered plants and
an insect.
