Partnership Map

West Maui Mountains Watershed Partnership Map

The Partnership is a voluntary alliance of public and private landowners driven to preserve and protect nearly 50,000 acres of the forested core of West Maui. The Partnership's efforts are concentrated in the West Maui Mountains, also known as Mauna Kahalawai, where elevations range from sea level to 5,788 feet at the summit.  

The Partnership's management area encompasses around 10% of Maui Island and includes both wet and dry forest landscapes, knife ridges and deep valleys.
