Watershed threats do not recognize landownership boundaries. This is why the Partnership, in which a forum is provided for partners to share costs, information and expertise to promote good stewardship of the land, is so critical to protecting our productive forests.  Landowners who own more than 100 acres within the partnership boundaries are invited to participate in the Partnership.

All participating partners agree that the Ko’olau Mountains Watershed is an important watershed for O’ahu. The partners also concur that pro-active management of the watershed is crucial in eliminating or reducing the threats of damage to the watershed due to weeds, insects, disease, feral ungulates, and in some instances, human impacts. They agree to work together to formulate watershed projects for the mauka regions of the Ko’olau mountains and join in cooperative efforts to seek funds for these projects.
