The Environmental Compliance & Protection Division join forces with the 3rd Marines’ Combat Assault Company (CAC) to help control an invasive plant and preserve endangered bird habitat in the Nuʻupia Ponds Wildlife Management Area. The three-day operation called “Mud Ops” has been a consistent training opportunity for the CAC since 1970s.

Republic P-47 Thunderbolts lined up for inspection at Bellows Field (now Marine Corps Training Area Bellows) during World War II. The P-47 was the largest fighter aircraft powered by a single-piston engine. It was heavily armed with eight .50-caliber machine guns and up to 2,500 lbs of Bombs.
Ulupa’u Crater WMA is home to one of two breeding colonies of Red-footed Boobies (Sula sula rubripes) in the main Hawaiian islands – the other is located on Kauai’s Kilauea Wildlife Refuge managed by the US Fish and Wildlife Service, Refuge division. The WMA supports approximately 2500 – 3000 Boobies.
Hangar 101 under attack on 7 December 1941 by Japanese of the Imperial Navy. Hangar 101, the five seaplane ramps, and the parking apron are now part of the National Historic Landmark (NHL). NHLs are the nation’s most significant historic places that possess exceptional value in illustrating or interpreting the heritage of the United States.
Each year the Environmental Dept engages 3rd Marines’ Combat Assault Company (CAC) to perform the annual site preparation for the endangered Hawaiian Stilt breeding season (Mar-Sep). The CAC’s Amphibious Assault Vehicles (AAVs) are used to break-up the non-native invasive pickleweed or akulikuki kai (Batis maritimas) covering the mud flats used for nesting. This annual 3-day operation known as “Mud Ops” has been a yearly event since 1982, and is usually conducted mid-February. Besides supporting the Environmental Dept’s management objectives for the Nu’upia Ponds, the Marines operating the AAVs are provided a unique and valuable training opportunity.
Fort Hase archaeological site is located along the eastern edge of Mokapu Peninsula. Evidence of an ancient Hawaiian fishing camp is buried below the grassy surface. It is likely that the abundant resources on the peninsula drew the inhabitants to the site. Radiocarbon dating of an old fire pit indicates that the site was inhabited about 600 years ago.
Archaeologists in the field carefully record the rock features that are the former house sites and agricultural fields of Hawaiians that once lived on Mokapu Peninsula.
On July 16, 2009, only the 3rd documented Olive Ridley turtle nesting in Hawaii occurred aboard Marine Corps Base Hawaii on Pyramid Rock Beach. The MCB Hawaii egg hatching was the most successful of the three events – over 50% of the eggs hatched. With the exception of nesting in Hawaii noted above, there is no nesting by this species anywhere in the United States or the territories under U.S. political jurisdiction.
Archaeologist coring in Nuupia Fishponds to extract sediment samples. These samples provide evidence of pond formation and pollen from the different plants that once lived along the ponds. The sediment from the core indicates that the fishpond was likely constructed by ancient Hawaiians about 700 years ago.
Base Cultural Resources Manager observing the stratigraphy (different layers of soil) in an excavation. The soil layers can help explain the events that have occurred in the past, showing ancient living surfaces and may include evidence of types of food people ate, the tools they made, and the types of houses they lived in.

Marines from the Fleet Assistance (FAP) and Wounded Warrior Programs have been provided an introduction to archaeology, including field techniques and laboratory analysis. The laboratory analysis looks at the midden (sea shells and food refuse) left behind to determine what was eaten.

The Environmental Compliance and Protection Department carries out the functions of compliance, pollution prevention, conservation, installation restoration, and training, education, and outreach at MCBH such that we contribute to the combat readiness of our Marines, and protect human health and the environment.
