About PROTECT & PRESERVE HAWAII INC

Protect & Preserve Hawaiʻi (EIN 83-3415430) is a Honolulu-based 501(c)(3) conservation nonprofit founded in 2019 that restores and protects native ecosystems across Oʻahu, operating a large restoration site in Pia Valley and community programs mauka-to-makai. The organization runs volunteer restoration days, native outplanting and seed-collection efforts, tree-donation programs with a live tree-tracker, and the Satellite Rain Garden Initiative to reduce stormwater runoff and support biodiversity. Protect & Preserve Hawaiʻi emphasizes community engagement and cultural stewardship through partnerships with local conservation groups and programs that train and mobilize volunteers; recent organizational activity includes quarterly newsletters and regular volunteer events, and the group reports active metrics including hundreds of monthly volunteers and thousands of native outplantings. The organization has scaled operations and received foundation support in recent years while maintaining an active public-facing donor and volunteer program.
