October brings a special kind of magic to Aloha Tree Alliance as we celebrate the start of our 2024-25 planting season! With fresh goals, vibrant seedlings, terrific volunteers and a continued dedication to improving Hawai‘i’s watersheds, we’re ready to dive into another season of transformation and growth. Throughout the next eight months of this planting season, we’ll gather to plant 300 native trees and shrubs each month, nurture even more, and connect with the land that continues to sustain us. Mahalo to everyone for helping us make a lasting impact in the Kuli‘ou‘ou watershed. We look forward to many more great work days together!
From Grassroots to Government
Propelling into Planting Season


Among our volunteers were three school groups: students from Kaiser High School’s Interact Club, middle schoolers from Hālau Kū Māna (who uplifted us with their beautiful voices through a Mahalo Oli at the day’s end), and Roosevelt High School’s Green Horizons club, led by Leo Tokumi, an Eagle Scout who completed his project requirements with ATA earlier this year.

Groundbreaking News at the ATA Nursery!

While Hawai‘i may not flaunt the fiery fall colors of other places, this autumn season brings transformation to ATA’s restoration work in its own way. A once-bare plot in Kamilo Nui Valley now hums with activity: debris clearing, concrete pouring, and gravelling worksites have all laid the foundation for ATA’s Native Hawaiian Plant Nursery. With the shadehouse structure making its way to O‘ahu, it won’t be long before this space comes alive with thousands of seedlings, poised to take root and thrive along the Kuli‘ou‘ou Ridge Trail. Change is in the air, and it’s just the beginning. Stay tuned!
Sharing ‘Ike with Our Elected Officials

Senator Hirono and her staff were joined by representatives of the National Oceanic and Atmospheric Administration (NOAA), Mālama Maunalua (MM), and ATA. Together, the groups planted Koa in an affirmation of the coastal partnership that unites them.

A few weeks later, Representative Ichiyama and her team joined ATA and Protect and Preserve Hawai‘i staff for a restoration site tour at the Kuli‘ou‘ou Ridge Trail, followed by an engaging limu huki (seaweed pull) with MM and a tour of Kānewai Spring with the Maunalua Fishpond Heritage Center. Through these visits, ATA grows meaningful relationships with many individuals and groups who share the goal of building a better Hawai‘i.
Mahalo to Representatives Ichiyama and Hashem for spearheading the ridge-to-reef tour, and to MM for elevating ATA’s work and for being a powerhouse organization in the Maunalua area!
Coqui Frogs Threaten Kuli‘ou‘ou Valley


“Besides the ecological impacts, there are a lot of cultural impacts with invasive species. The sound of the wind in that area, which is called Pu’uokona [and] the sound of the rain, Naulu, will be erased if coqui frogs persist in Kuli‘ou‘ou. It is part of what makes Hawai‘i, Hawai‘i.”
– Ryan Chang, DOFAW field technician, in an interview with Hawaii Public Radio.
Containment efforts are underway to prevent the spread of this infestation down Kuli‘ou‘ou Valley. DOFAW has begun sending drones equipped with a citric acid dilution to spray other frog-infested sites in Waimānalo. Citric acid, according to DOFAW, is lethal to frogs but does not cause serious or lasting injury to insects, birds, or people. DOFAW has also begun engaging the community through volunteer frog capture events. The sign-up form is linked here, but please note that volunteer capacity is limited based on staff availability.
If you suspect that you’ve heard coqui frogs, please report the observation to the O‘ahu Invasive Species Committee. More detailed information can be found at https://www.oahuisc.org/species/coqui-frog/.

Biodiversity: a Botanical Melting Pot
Trees may dominate the scenery of ATA’s restoration kīpuka, but their importance must not overshadow the other biodiverse plant species working hard to stabilize soil, produce oxygen, and sequester carbon. Biodiversity is the variety of all life in a given habitat, and it denotes the breadth of ecosystem services–pollination, water purification, oxygen production, and nutrient cycling, and more–that are performed by those organisms. “Biodiversity is an essential part of ecosystem resilience because it allows the ecosystem to adapt to changing climates, disease, and to preserve essential symbioses,” said ATA Field & Nursery Manager Eli Livezey. ATA fosters biodiversity by planting more than 15 species of native trees, shrubs, and groundcover in Kuli‘ou‘ou Valley. In restoring plant biodiversity, ATA hopes to increase the diversity of insects, fungi, and other key players in the ecosystem – some of which depend on a single native plant species for survival.

ATA understands that every plant in the ecosystem—from a towering Koa to a sprawling Ilie‘e—plays a unique role. Together, they thrive in a biodiverse environment, supporting each other and strengthening the forest.
119 Years of Green

While National Arbor Day falls on the first Friday in April, Hawaii celebrates in November to align with the rainy season, the ideal time for planting. Join Aloha Tree Alliance on Friday, November 1st for our Aloha Friday Watering event to nurture new seedlings and existing trees and shrubs on the Kuli`ou`ou Ridge Trail. Then, on Arbor Day itself– November 2nd–participate in tree giveaways and other fun events sponsored by the Department of Land and Natural Resources (DLNR) Kaulunani Urban and Community Forestry Program to support our forests and make a lasting impact on Hawaii’s future!

Trees on the Trail: Milo

This tree was and continues to be esteemed for its many uses. During World War II, Milo was one of the few plants acknowledged as an emergency food source in a manual called, “Emergency Food Plants and Poisonous Plants of the Islands of the Pacific.” Their young leaves and flower buds were found to be edible, while other parts of the tree are considered to be mildly poisonous. Its inner bark provided essential fiber, the outer bark was fashioned into cordage, and its fruits yielded an exquisite yellow-green dye.
Energetic Environmentalists Hit the Trail
Hālau Kū Māna 8th Graders Open a New Kīpuka

Their enthusiasm was contagious, and some students returned to volunteer during our community work day, deepening their connection to the land. We’re excited to welcome Hālau Ku Māna back to the trail again later this school year when the students will experience the other side of restoration work—planting in the new kīpuka they helped create!

Partnerships in Sustainability
Just as the different elements of an ecosystem are interconnected with each other, our community’s various sustainability efforts must be as well. Aloha Tree Alliance operates knowing that collaboration is the foundation of a sustainable future. We are so grateful for all of our partner organizations and their respective missions, commitment to the vitality of our planet, and desire to work as a community.

ATA would like to express sincere appreciation to The Coconut Traveler, Xylem, The Garden Club of Honolulu, and the National Oceanic and Atmospheric Administration for their financial support. These grantors have enabled ATA to fund its growth in education capacity, restoration progress, and personnel. Furthermore, by expressing their support, these grantors have magnified the reach of ATA’s mission.
