Marine Corps Air Station Iwakuni, Japan


Marine Corps Air Station Iwakuni, Japan

MCAS Iwakuni is a mission-ready air station, capable of providing continuous base-operating support for tenant organizations and follow-on U.S. and allied forces during training, combat or contingency (HA/DR) operations throughout the Indo-Asia Pacific region.
Natural Resources Program

Nearly the entire Air Station is artificially maintained and cannot be characterized as environmental rich in natural resources. However Penny Lake, North and South Retention ponds provide temporary habitat for a variety of Japanese resident and migratory birds.

Natural Resources Surveys are being conducted aboard the installation, and the surveys include small mammals, birds, reptiles, amphibians, fish, insects and flora (plants) to update the inventory and to develop effective conservation/management plans for the natural resources on MCAS Iwakuni, and to support bird/wildlife aircraft strike hazard (BASH) programs.

Here are some of the species identified on MCAS Iwakuni during surveys in 2017.
