About

The Hawai‘i Sentinel Landscape spans over two million acres, featuring priority Department of Defense (DOD) installations, conservation, and agricultural lands on the islands of Kaua‘i, O‘ahu, and Hawai‘i. Given Hawai‘i’s limited land availability, these areas present a unique opportunity to conserve natural and cultural resources, mitigate encroachment threats, and promote land use that complements military activities.

Key military installations within this landscape include: Pōhakuloa Training Area on Hawai‘i Island; Pacific Missile Range Facility on Kaua‘i; and Marine Corps Base Hawai‘i, Joint Base Pearl Harbor-Hickam, and U.S. Army Garrison Hawai‘i on O‘ahu. These installations help maintain a regional power balance in the Indo-Pacific by deterring aggression. Their strategic locations enable coordinated training that builds a resilient and innovative Joint Force.

In Hawai‘i, development threatens agricultural lands, native forests, and critical habitat while also obstructing military activities like low elevation flight and drone training, radar, and communication antennas. Environmental threats further challenge military readiness and critical infrastructure, community resilience, and water quality and quantity. For example, weather events erode shorelines, increase flooding, and impact underground aquifers. Extended drought periods impact freshwater resources and lead to more frequent wildfires.

The Hawai‘i Sentinel Landscape fosters a growing partnership of nearly 20 Federal, state, local, and private partners to collaborate on landscape-scale solutions to address these shared challenges.
