Ko’olau Mountains Watershed Partnership


About the organizer

KMWP works across over 103,000 acres of the Ko’olau Mountains. Our partnership was formed with the goal to protect our watershed resources and increase the recharge of our aquifers with high quality water through active conservation of our forested lands.

We work across landowner boundaries to eliminate threats to the watershed such as habitat-modifying invasive weeds and ungulates like goats and wild boars. Our focus is on combining protection with restoration using a adaptive management strategies and established conservation practices. These methods include the installation of ungulate-proof fencing, various weed removal techniques, restoration planting, and long-term monitoring.

We also reach out to local communities, individuals, and organizations to empower them with the knowledge and skills needed to become effective stewards of their land. We host educational presentations, workshops, and service-learning opportunities, to give everyone the chance to learn about and protect the native ecosystems and watershed resources of the Ko’olau Mountains.
