Celebrating the Year of our Community Forests

community-forest

Forests are more than trees—they are the lifeblood of our islands, connecting us to the land and enriching our daily lives. This year, as part of the Department of Land and Natural Resources (DLNR) statewide Year of our Community Forests campaign, Aloha Tree Alliance is thrilled to partner with DLNR and other organizations across Hawai`i to “celebrate trees in our wao kanaka, where we live, learn, and play.”

Get ready for a year of inspiring opportunities from ATA and partners across the state for arboreal education, community building, and stewardship in your community forests. Stay connected to join the movement!

745 Reasons to Celebrate

Reasons-to-celebrate

Since the planting season launch last October, 745 native plants—spanning 10 diverse species, from the sprawling Ilie‘e to the majestic Ōhiʻa lehua—have taken root along the Kuli‘ou‘ou Ridge Trail! Some of these young plants now flourish among existing kīpuka, while others are pioneering new sections of the ridge.

This incredible milestone was achieved thanks to the efforts of over 300 passionate volunteers from our local community and schools, who joined us to learn and plant. Through their tireless dedication to clearing dense groves of invasive Haole koa, Opiuma, and Strawberry Guava trees, ATA volunteers are transforming dry hillsides into thriving habitats for native biodiversity!

Planting the Way Nature Intended

planting

This season, ATA is embracing nature’s wisdom to refine its restoration approach. Traditional reforestation often follows a grid-like planting pattern on flat land to prevent overcrowding, but natural forests tell a different story. On the Kuli‘ou‘ou Ridge Trail, wild Alahe‘e trees grow in tight clusters, sometimes less than six inches apart. Could this proximity enhance resource sharing through mycorrhizal networks or facilitate reproduction? Furthermore, wild ʻŪlei are most commonly spotted hugging Kuli‘ou‘ou’s rugged hillsides. Despite these “unconventional” conditions, the plants thrive.

“This season, ATA has been observing and reflecting on the remnant native species in Kuli‘ou‘ou to gide our restoration. We see the success these plants have and want to emulate their habits.”

– Eli Livezey, ATA Field and Nursery Manager

Livezey adapted ATA’s planting strategy to reflect nature’s design. Alahe‘e are now planted in loose clusters, 3’-5’ apart, mimicking natural patterns. Echoing natural layers of the forest, the trees are densely flanked by shrubs like ‘A‘ali‘i and groundcover like carex, which support the forest floor’s health and reduce water loss by shielding the soil from evaporation.

By tuning in to the land and embracing its wisdom, ATA is nurturing a more resilient, self-sustaining forest– one that thrives not despite, but because of its wild dynamics.


Every Drop Counts

Every-drop-counts

In the Kuli‘ou‘ou watershed, every drop of water plays a vital role–whether it’s funneled into catchments, absorbed by thirsty roots, or replenishing the aquifer. Water sustains life, and for Aloha Tree Alliance, it’s the lifeline for our restoration efforts. We’re delighted to announce the addition of two new rainwater catchment totes that will increase our water collection capacity by 500 gallons! These systems not only ease the strain on our water supply but ensure our young native plants receive the hydration they need to thrive. Mahalo to the Department of Forestry and Wildlife crew for helping to keep the new totes full and boosting sustainability in the watershed!


Managing Your Footprint

Managing-footprints

Have you noticed the new boot brush station at the first switchback of the Kuli‘ou‘ou Ridge trail? Boot brushes are key tools in protecting Hawaii’s delicate ecosystems, but they only work when you do your part. By wiping your boots and spraying them with a 70% isopropyl alcohol solution before and after your hike, you can prevent the spread of invasive seeds and pathogens like Rapid ʻŌhiʻa Death (ROD). These simple steps help to protect the ‘āina, one footstep at a time.

Nature’s Classroom

SEEQS Students Dig Deep

Dig-deep

Did you know that the area now known as downtown Honolulu was once so abundant with Kou trees it was called Kou (City & County of Honolulu Archives, 2004)? Or that Kou was traditionally used medicinally to treat thrush (DLNR, 2024)? These insights were shared during Aloha Tree Alliance’s recent classroom collaboration with students from the School for Examining Essential Questions of Sustainability (SEEQS).For the second consecutive year, ATA partnered with SEEQS’ middle school class for a classroom visit and a field trip to Kuli‘ou‘ou Ridge Trail. In the classroom, students learned planting techniques, explored facts about Kou and the intrinsic value of forests, and played a plant identification game that got them excited about Hawai‘i’s native species. On the trail, the students planted 18 Kou trees, applying the planting techniques they learned in the classroom. They dug deep holes to avoid root exposure, added fertilizer and water absorption crystals, and packed soil to eliminate air bubbles.

ATA’s staff believes fostering a connection with nature is the first step in cultivating dedicated environmental stewards. Mahalo to the SEEQS community for joining us in our mission with their passion, energy and partnership!

Wiliwili are Back in Action!

In the summer, Wiliwili (Erythrina sandwicensis) trees on the Kuli‘ou‘ou Ridge Trail looked like dessicated, leafless sticks, but don’t worry—they were just in dormancy.

Erythrina sandwicensis, an endemic drought-resistant species, conserves its resources in the summer by dropping its leaves and photosynthesizing through its bark. With its deep root system, the Wiliwili draws water from deep in the soil, avoiding energy loss by not transporting water and nutrients beyond its trunk. This nitrogen-fixing tree enriches the soil by converting atmospheric nitrogen into a form that can be absorbed by itself and neighboring plants.

wiliwili-action

A Hawaiian proverb reminds us, “Pua ka wiliwili, nanahu ka mano” — when the Wiliwili blossoms, sharks bite. Native Hawaiians keenly observed and understood the cycles of mountain and sea, and recognized that Wiliwili blooms coincided with shark breeding season. Next time you spot a Wiliwili tree, remember its varied roles: a seasonal indicator, a fixer of atmospheric nitrogen, and a key member of this ecosystem!

 


 

In between studying psychology at the University of Hawai‘i at Mānoa, playing competitive volleyball, and her part-time jobs, Logan Kaneshiro makes time to hit the trail on Friday mornings. Logan’s easygoing attitude and work ethic have been much-appreciated since her first time volunteering last summer.

Mahalo Logan for your hard work and enthusiasm!

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. 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.

Partnerships in Sustainability


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, community engagement, and personnel.
