If you were on the back nine at dawn sometime after Memorial Day, you may have noticed something missing. Not the ocean, which is still doing its usual work along Kohanaiki's mile and a half of coastline. Not the wind, which never quits up here. What's gone is the sound of an engine. A 100-inch mower has been gliding across the fairways with no one behind the wheel, and no exhaust trailing behind it either.
That machine showed up on May 26, 2026, and it wasn't an accident of timing. To understand why, you have to back up a month, to an award most members probably skimmed past in a club newsletter and moved on.
The award that isn't really about the golf course
In April 2026, Kohanaiki's course became the first in Hawaii to earn Audubon International's Gold Signature Sanctuary certification, placing it among just 14 courses worldwide to hold that status within a global network of more than 2,000 certified properties. That's a genuinely small club. The certification covers the Rees Jones design most members already know by feel: 18 holes, par 72, roughly 7,400 yards of lava-field fairway with several holes running straight along the water. Jones, the son of golf course architect Robert Trent Jones Sr., has built or renovated more than 300 courses over six decades, and Kohanaiki's is now the only one of his in Hawaii carrying this particular distinction.
But read past the headline and the certification isn't really a statement about tee boxes or green speeds. It's a statement about what's underneath them.
What's actually living in those ponds
Kohanaiki's grounds hold more than 200 anchialine ponds strung along the coastline, some no bigger than a fist, a few as large as a swimming pool, with roughly 30 of them clustered around the 14th green alone. These are brackish, tide-fed pools that form in old lava rock, fed by groundwater from above and seawater seeping in from below. They're rare enough globally that a golf course built around this many of them is unusual on its own.
They're also home to the Hawaiian stilt, or Ae'o, a wading bird found in its largest island population right along this stretch of the Kona coast. The Department of Land and Natural Resources notes that Ae'o nesting runs from March through August and peaks in May and June, with parents laying three to four eggs and defending the nest aggressively, calling and performing broken-wing displays to lure anything that gets too close away from the chicks.
That's the window Kohanaiki's certification was built around. Luke Bennett, the club's Director of Golf Course Maintenance and Grounds, put it plainly when the award was announced: protecting the anchialine ponds and the Ae'o nesting grounds guides the crew's work every day, not just during audit season. President and CEO David Reese framed it the same way, describing the certification as a reflection of everyday practices rather than a one-time project.
So when you see a grounds crew keeping a wider berth around a pond in June, or notice a section of rough left a little longer than usual near the water, that's not neglect. It's the buffer zone the certification requires, timed to the exact eight weeks when the birds nesting a few feet from the fairway are least able to relocate.
Why the mower landed in the middle of nesting season
Which brings the story back to that quiet machine on the back nine. The FireFly Automatix AMP-L100 is a fully autonomous, all-electric reel mower, a 100-inch, five-gang unit built for large-scale fairway work. It runs without a driver, using precision guidance to hold a consistent line across the course, and it does the job without the noise or emissions that come standard with gas-powered equipment. Kohanaiki is the first club in the Hawaiian Islands to put one to work, and the mower itself picked up a 2026 Innovator Award from the Sports Field Management Association.
Here's the part worth sitting with: it arrived on May 26, seven days into the peak stretch of Ae'o nesting season. A course that just spent months proving to Audubon International that its everyday operations protect nesting shorebirds then deployed the one piece of equipment least likely to disturb them, at the exact moment disturbance would matter most.
| Typical gas fairway mower | Kohanaiki's AMP-L100 | |
|---|---|---|
| Power source | Combustion engine | Fully electric |
| Operator | Human driver | Autonomous, no operator |
| Cutting width | Varies by unit | 100 inches, 5-gang reel |
| Emissions during operation | Yes | None |
| Engine noise near nesting ponds | Present | Absent |
That's not a coincidence you'll find spelled out in a press release. It's just what happens when a certification stops being a plaque in the pro shop and starts showing up in the equipment budget.
The rest of the club didn't stand still either
None of this happened in isolation from the rest of Kohanaiki's calendar. Executive Chef Robin Nishizaki, who came up under Wolfgang Puck in Beverly Hills before running kitchens at Spanish Hills Country Club and Montecito Club, still has the kitchens at Kōnane and the Beach Restaurant pulling from more than 40 local and Hawaii-based farms, with line-caught fish, upcountry lamb, and produce from the club's own farm rotating through the menus at both. A Certified Cicerone Beer Server who home-brews on the side, Nishizaki runs the kind of program where the sourcing conversation isn't so different from the one happening out on the course: know where it comes from, and don't waste it.
On the golf side, May also brought the club's inaugural Longboard, a three-day couples' member-guest tournament that closed registration on May 22, just days before the mower rolled out and right as nesting season hit its peak. Practice round, two tournament rounds, evenings built around food and company rather than leaderboard pressure. It's the kind of event that fills the clubhouse calendar without asking anyone to think about anchialine ponds at all, which is sort of the point. The stewardship work is supposed to run underneath daily life here, not compete with it.
What this actually changes if you're already here
If you play Kohanaiki regularly, the practical takeaway is small but real. Expect wider staked buffers around certain ponds through August. Expect the grounds crew to explain, if you ask, why a patch near the 14th looks a little different than it did last winter. And expect the quiet mower to keep showing up at odd hours, because running equipment during cooler, calmer parts of the day is part of the same low-impact approach that earned the Gold Signature Sanctuary status in the first place.
The certification made news because it's rare. The mower made news because it's a first for the islands. But the reason both happened in the same six-week window is the part that doesn't fit neatly into a press release: Kohanaiki timed a genuine operational shift to line up with eight weeks when a protected bird is raising its young a few yards from the cart path, and most of the people playing through never had to notice.
If you're weighing what life inside a gated golf community on the Kona Coast actually looks like day to day, that's a more honest answer than any brochure.
