Since 2001, approximately 25 acres of invasive mesquite tree, buffalo grass, and Pluchea sp. have been removed. To date, about 15 acres have been replanted with endangered and rare native species and natural recruitment of native species has occured throughout the 25 acres. The majority of the work is performed by volunteers however, project funds were used to contract services to mechanically remove and haul away invasive plant species that out-compete endangered and rare plant species for valuable sunlight, water, and nutrients.

Interpretive signs explaining restoration efforts at Kalaeloa are being developed from funding for this project and restoration of limestone sinkholes, which are one of the most threatened aquatic ecosystems in the State of Hawaii. The limestone sinkholes are the O`ahu analogs of the anchialine ponds found in the lava fields on the Big Island of Hawaii. Like the anchialine ponds, these sinkholes support a unique aquatic ecosystem centered around the rare opae ula shrimp.

Some benefits of this on-going project include: Engaging and informing the local community about native Hawaiian resources, federally endangered species, and the fragile balance of ecosystems within the Ewa Plain, providing educational and outdoor opportunities for present and future generations, and restoration and recovery of endangered and rare species and ecosystems at risk of extinction.
