The Hawai‘i Forest Institute (HFI) and the Hawai‘i Forest Industry Association (HFIA), along with community partners completed the Phase I of the Pana‘ewa Zoo Discovery Forest in 2011 and Phase II  in 2013.  Over 1,000 community volunteers have participated in creating native and agro-forest demonstration gardens. In Phase II, a main project kiosk, Native and Polynesian-introduced interpretive signs, and Plant ID signs were installed.

The Discovery Forest receives quarterly groomings, courtesy of the Kiwanis Club of East Hawai’i ohana under the direction of Outreach Coordinator Mika Gallarado.  Kiwanis Club members and their sponsored youth clubs volunteer to help maintain and enhance the Discovery Forest. 

Each summer, 80 Kamehameha Schools students volunteer their time at the Discovery Forest.  June 25, 2019 was Kamehameha Schools last volunteer day.  The students learned about the history and significance of the Native and Polynesian-introduced plantings before planting seedlings and weeding.

Other volunteer groups have included Hawaii Academy of Arts and Science, UH Hilo students, Hilo Boy Scouts, Innovations Academy, Pacific Quest, Malamalama Waldorf students, Circle K, Ka’ū High School students, Ocean Awareness Training Group, Hilo High Key Club, Ford Leadership Group, Prince Jonah Kūhiō Kalani‘ana‘ole students, Hilo Intermediate School Builders Club, De Silva Intermediate School, as well as communtiiy volunteers and visitors.

The project is providing education, recreation, and volunteer opportunities for community residents and visitors.

In the Summer of 2013, 80 Kamehameha Schools 1st grade students visited the Discovery Forest this summer.  Four groups of 20 students spent an hour pulling weeds and planting seedlings.  See gallery here.

The Discovery Forest features a demonstration of native, cultural, and medicinal plants. Culturally significant plants that once grew in the traditional farms and native forests of East Hawai‘i are featured in the Discovery Forest, including Polynesian-introduced plants that arrived with migrations in voyaging canoes. These “canoe plants”, along with many endemic species, play essential roles in Hawaiian culture, for food, fiber, tools, implements, building materials, and medicine. Many of these culturally significant plants have found a place in the Discovery forest.

Prince Jonah Kūhiō Kalani‘ana‘ole Elementary and Intermediate School first grade students planted native Hawaiian plants and learned from native plant experts at the Pana‘ewa Zoo Discovery Forest.  See gallery here.

A group of 80 Kamehameha Schools first grade students have visited the Discovery Forest several times to clear weeds, plant seedlings, and learn from native plant experts.  See gallery here.

In addition to area school and community groups such as Pacific Quest, Kiwanis Kids are helping to create and maintain the Discovery Forest. Landscape Architects, Leonard Bisel Associates (LBA) created thoughtful preliminary native and agro-forest demonstration design plans.  Kiwanis Kids Gallery

Native Forest Plan

The native plan provides a tiered effect of native trees, plants, and groundcovers including Naupaka kuahiwi (Scaevola gaudichaudii), Maile (Alyxia stellata), Hāpu‘u pulu (Cibotium glaucum), Kōlea (Myrsine lessertiana), and Kōpiko (Psychotria hawaiiensis). Boulders, gravel rock, and stepping pavers provide for a low maintenance viewing platform and add visual interest. Native species will be outplanted among existing native species including Lama, Hāpu’u pulu, and ‘Ōhi‘a.

Agro-forest Plan

The agro-forest features a strategically-placed viewing platform overlooking low, mid and higher canopy species such as Awa, (Piper methysticum, Noni (Morinda citrifolia), Ulu (Artocarpus altilis), and Milo (Thespesia populnea). An existing Kukui (Candlenut) and palms are incorporated into the design. Edged planting beds, stone groundcovers, and decorative pavers enhance the plantings.

The Phase II plan blends the Native and Agro-forest gardens.

Mahalo to LBA for donating 50% of their design services.

HFIA is seeking monetary and in-kind donations through the Hawai‘i Forest Institute, a 501 (c) (3) nonprofit organization. Volunteers and contributions are needed for planting seedlings, caring for new plants, plants and planting materials, interpretive features, and hardscape materials.
