At High Regard, our team provides ISA-certified arborist services in Honolulu and across Oahu, caring for residential, commercial, and municipal properties with the precision and craft these trees deserve.

Arborist Services in Honolulu: What Makes Tree Care Here Unique

Honolulu’s microclimates are some of the most varied of any American city. A property in Mānoa Valley deals with very different conditions than one in Kakaʻako or Diamond Head — and tree care that ignores those differences usually shows up as a problem six months later.

Mauka neighborhoods (Mānoa, Nuʻuanu, Pālolo) get significantly more rainfall than the coast, which means higher fungal disease pressure, faster canopy growth, and trees that need more frequent pruning.
Coastal areas (Waikīkī, Kakaʻako, Diamond Head) face salt spray, drier soil, and higher wind exposure — issues that benefit from different species selection and proactive monitoring.
Urban core neighborhoods (Downtown, Chinatown) have mature street trees with confined root zones, often near power lines, sidewalks, and historic structures that demand careful, precise work.

Knowing the specific challenges of each area is the difference between a tree job that lasts and one that creates problems six months later.

Trees We Care for Across Honolulu

Honolulu’s tree population is unusually diverse for an American city — a legacy of more than a century of intentional planting, plus the unique conditions that allow species from around the world to thrive side by side. Our team regularly cares for:

Monkeypod (Albizia saman) — Honolulu’s iconic shade tree, present in nearly every park and on countless residential lots. Many of the largest specimens trace back to seeds first planted in Honolulu in 1847.
Indian banyan (Ficus benghalensis) — Including the century-old banyans at ʻIolani Palace and the Moana Surfrider Hotel, many of which are listed in Hawaii’s Exceptional Trees registry.
Royal poinciana, shower trees, and plumeria — The flowering trees that give Oahu’s neighborhoods their seasonal color.
Coconut, royal, and Mexican fan palms — Increasingly threatened by the coconut rhinoceros beetle (CRB), which has been spreading across Oahu since 2013. Our team is specifically trained to identify and address CRB damage.
Mango, avocado, and breadfruit — Fixtures of older Honolulu residential properties, often requiring specialized fruit-tree pruning to maintain yield and structure.

Honolulu’s Exceptional Trees and What They Mean for Property Owners

Hawaii’s Exceptional Tree Act, passed in 1975, was the first program of its kind in the United States. It legally protects trees of significant historical, cultural, or environmental value — and Honolulu has more designated exceptional trees than any other city in the state.

If you own or manage property in Honolulu, this matters more than most people realize. Pruning, treating, or removing an exceptional tree without proper authorization can result in significant legal penalties — even if the tree is on your own land.

Some examples of Honolulu’s exceptional trees include the giant monkeypod at Moanalua Gardens (used as Hitachi Corporation’s global corporate logo), the Iolani Palace banyans, the towering kapok on Keeaumoku Street, and the American mahoganies along Kalakaua Avenue. The registry includes hundreds of trees scattered across the city, including on private property.
Our ISA-certified arborists are familiar with the registry and the permit processes that come with working on protected trees, so property owners and managers can move forward with confidence.

Frequently Asked Questions

Here are some questions people often ask about our Honolulu tree services. If your question isn’t listed here, feel free to reach out, and we’ll be happy to help.

Hawaii’s Department of Land and Natural Resources maintains a public registry. If you’re unsure, we can check the registry for you during a free consultation — and if your tree IS designated exceptional, we can guide you through the permit process required before any work.

Yes, this is a real and growing concern across Oahu. CRB has been confirmed in Honolulu since 2013 and is now considered widespread. Distinctive V-shaped notches in palm fronds are the telltale sign. Our team can assess your palms, identify CRB damage at early stages, and recommend treatment options.

Yes. We’re available 24/7 for urgent tree issues like fallen trees, broken limbs, or safety risks. Quick response helps prevent property damage and injury. We prioritize emergency calls and arrive with the equipment needed to stabilize or remove the hazard quickly.

If the tree is leaning, showing signs of internal decay, or interfering with structures, it might be time to consider removal. We’ll inspect it and walk you through the safest options. Sometimes pruning or treatment can help, but we’ll be honest about what’s best. A full risk assessment will give you a clearer picture of whether your tree is a liability.

We assess your trees during a full walkthrough and share expert insights on health, structure, and safety. You’ll receive recommendations based on your property’s layout and your goals. It’s a smart way to get ahead of any problems. This service is especially helpful if you’re planning future landscape work or have concerns about specific trees.

That depends on the species, location, and health of your trees. Most benefit from annual or seasonal pruning. We can help set a schedule that fits your landscape. Regular pruning also helps improve tree shape, reduce hazards, and promote healthy growth.
