Pōhakuloa Training Area (PTA) (lit. long stone) was first
used during World War II as a Marine Corps artillery live-fire training area.
During World War II, few permanent structures existed; when
the Marines trained at PTA, they slept in tents.
U.S. Marines from the 3rd Marine Division and the 5th Marine
Division trained at PTA and on the western side of the Big Island in
preparation for the Iwo Jima and Saipan campaigns.
After the war, PTA fell under the control of the Hawai‘i
Territorial Guard and in the mid-1950s the Army took over PTA. From 1955-58,
Soldiers from the 65th Engineer Company built the distinctive Quonset huts,
which are still in use.
The training area is about midway between Hilo on the east
coast and the Army landing site at Kawaihae Harbor on the west coast. PTA extends up the lower slopes of Mauna Kea
to approximately 6,800-feet in elevation and to about 9,000-feet on Mauna Loa.
The area is the largest Department of Defense (DOD)
installation in Hawaiʻi. PTA's 130,000-acres include an 80-acre
cantonment area (headquarters, housing and other facilities) with a fuel yard,
fire and police departments and an airfield with a 3,700-foot runway.
The installation can support up to 2,300-military personnel
with rations, fuel and transportation.
PTA's firing ranges allow units to conduct small-arms and
crew-served weapons familiarization training and qualifications, as well as
artillery and mortar live fire.
Through the years, PTA’s ranges and training areas have
helped Army, Navy, Air Force and Marine units maintain their combat readiness
and prepare for war.
Most recently, 25th Infantry Division units, Kaneohe-based
Marines and Hawaii Army National Guard Soldiers prepared at PTA for combat
operations in Iraq and Afghanistan.
Today, PTA stands as the premier military training area in
the Pacific region. Units from all U.S. military services, as well as allied
militaries, train at PTA, because it offers realistic training opportunities
not found elsewhere.
With several new construction projects underway, PTA looks
to support military training well into the future.
One of the great untold stories is the attention to native
plant restoration at PTA - from the low-tech nursery house and field plantings,
to high-tech digital terrain monitoring (using airborne light detecting and
ranging (LiDAR)) to define areas for plant restoration.
Dryland forests are among the most threatened of all
tropical forest ecosystems, largely because of the impact of grazing animals,
invasive species, fire and land conversion. Only about 5 percent of Hawaii
dryland forest habitats remain.
PTA's Natural Resources Team consists of about 40 employees,
who protect threatened and endangered species on the military property, grow
and monitor plants, construct firebreaks and remove invasive species. More than
2,000-endangered and common native plants are annually replanted into the wild.
Bird counters do visual checks for common and rare birds and
also identify many by their songs. The most common native birds encountered are
palila, nene, amakihi and apapane.
In addition, the Army is fencing off areas to protect it
from the damaging effects of goats, sheep and pigs (ungulates) to allow
recovery of mamane-naio forest.
Recovery of that forest may eventually lead to
reintroduction of endangered palila to the Pōhakuloa plain. The Army is presently trying to get most of
the fence-enclosed area cleared of unexploded ordnance so that public hunters
can assist in ungulate removal.

images of PTA in a folder of like name in the Photos section on my Facebook
