Urban Land Use features are shown along with existing tree canopy cover

Kaulunani conducted an Urban Tree Canopy Assessment of the major urban centers of O‘ahu. The study area includes 250 square miles of Leeward and Windward O‘ahu. This assessment identifies where trees are located, the extent of the canopy, as well as ownership and potential planting sites for enhancing the urban tree canopy.

Trees and tree-lined streets lead to more livable and cooler communities as well as healthier people. In addition, trees not only improve air quality, stormwater control and coastal water quality but also enrich businesses and provide energy savings.

The Urban Tree Canopy Assessment is part of the long range Hawai‘i urban forestry strategy planning initiative conducted by Smart Trees Pacific in collaboration with the USDA Forest Service; the State DLNR Division of Forestry and Wildlife, the Kaulunani Urban and Community Forestry Program; the City and County of Honolulu, Department of Parks and Recreation Urban Forestry Division, and the Department of Planning and Permitting, Honolulu Land Information System. 

City of Honolulu, Hawai‘i Municipal Forest Resource Analysis

2007 Technical report by the Center for Urban Forest Research, which combines results of a partial citywide inventory with benefit-cost modeling data. Value is calculated for benefits such as energy savings, CO2 reduction, air quality improvement, stormwater runoff reductions, aesthetic, property value, social, economic and other benefits.  The report is based on 43,000 inventoried street trees and thus represents only a fraction of the entire urban forest of Honolulu. Nonetheless, the value of these benefits is still substantial.

Planting Tips

Maui County Planting Plan

“The Maui County Planting Plan (MCPP) was prepared by the Maui County Arborist Committee… to serve as a guide for government officials, design and landscape professionals, and the public. It provides information on the planting, replanting, care, pruning, preservation, and disposition of Exceptional Trees, trees in general, and other landscape plants in Maui County parks and public rights-of-way.” (MCPP Preface)

Planting Details and Specifications (International Society of Arboriculture)

Dr. Ed Gilman from University of Florida, Jim Urban, FASLA, and Brian Kempf and Tyson Carroll of the Urban Tree Foundation have developed a modern, up-to-date, and peer reviewed set of details and specifications in AutoCAD, PDF, and Microsoft Word formats for the green industry. These are designed specifically for landscape architects, engineers, architects, contractors, urban foresters, arborists, municipalities, and state agencies.  All these files are open source, free, and can be edited by the user.

Exceptional Tree Program

“In 1975, the Hawai’i State Legislature found that rapid development had led to the destruction of many of the State’s exceptional trees and passed Act 105 – The Exceptional Tree Act. The Act recognizes that trees are valuable for their beauty and they perform crucial ecological functions. It mandates each county to establish a County Arborist Advisory Committee which enacts regulations to protect trees of exceptional stature. Each county has its own program, set of rules and operating guidelines.” More information can be found with the City & County of Honolulu’s Department of Parks & Recreation
