Love Maui's mountains and forests?

Want to learn more about our native plants and animals and help protect them?

Do you feel the need to do some community service?

If you answered yes to any of these questions, we invite you to join us on a volunteer stewardship hike, led by trained WMMWP crew members!  We love bringing students, hula halau, sports teams, business teams, and other community groups out into the mountain. 

Sign up to be on our volunteer mailing list to be notified about our next public stewardship hike.  Or, if you have a group you would like come out with us, please contact us.  


Waihee Ridge Trail

Waihee Ridge Trail is part of the State of Hawaii's Na Ala Hele trail system.  Beginning at an elevation of 1,000 feet, the trail continues 2.5 miles up Waihee Ridge to Lanilili.  From this pu'u, hikers are met with sweeping views into Waihee Valley, and depending on the weather, Mauna Eke, Makamakaole Gulch, and the slopes of Kahakuloa can also be seen.

Vegetation along the trail transitions through introduced tree and grass species at the trailhead and lower slopes to a more native landscape at the upper elevations, including plants like the well known ohia and lesser known 'ie'ie.  Problematically, the highly invasive strawberry guava (Psidium cattleianum) has begun to establish itself on the ridge.  Although many people know this tree for its edible fruits and ornamental qualities, this species spreads as an aggressive weed in the watershed that has taken over thousands of acres of native forest.  To combat its advance further into the forest, our stewardship trip leads volunteers to the front lines on Waihee Ridge to rid strawberry guava from the upper slopes.  Come and do your part!

Maunalei Arboretum

Established in the 1920s, the Maunalei Aboretum is nestled on the west side of the West Maui Mountains, above Kapalua.  The arboretum was established by a former plantation manager, D.T. Fleming, who collected a wide range of species from around the world.  This brochure describes the trail through the arboretum, as well as some native species that can be seen along the way: Maunalei Arboretum

In certain parts of the arboretum, problem species like Tibouchina herbacea, a habitat-modifying invasive weed, have begun to invade.  Thus, our stewardship trip into the Maunalei Arboretum involves hands-on control of this species to help mitigate its spread into the watershed.  The trip begins with an interpretive hike to orient participants with the dynamics of the native watershed and invasive species, and once the control area is reached, work begins!
