California wants to fine you per worker, per site

Regulators spent the week rewriting the math on penalties while three crews outside the trade got hurt and one worker in Bonita didn't come down. California's new citation rules are the story that reaches the most paychecks, so we'll start there.

The big one

Cal/OSHA opened formal rulemaking on October 16 to put teeth into Senate Bill 606, and the numbers should get the attention of anyone running more than one truck (JD Supra). Under the proposal, an egregious violation gets a separate penalty for each exposed employee. Send four climbers into the same bad situation and that's four penalties, not one. Enterprise-wide violations get multiplied by the number of covered worksites, capped at $162,851.

The part that will catch small outfits is the presumption. If a written policy is defective and applies across your worksites, or if Cal/OSHA finds the same violation at more than one location, the agency can presume the problem is enterprise-wide and make you argue your way out of it (Provisio EHS). The burden flips onto the employer. The proposal also tightens abatement certification from 10 calendar days to 10 working days and limits some penalty adjustments.

This is aimed at serial offenders, but tree work is exactly the kind of multi-crew, same-procedure operation that fits an enterprise-wide pattern. One sloppy job hazard analysis copied onto every truck becomes the evidence. Comments are due November 30, with a public hearing December 3. If you run jobs in California, read the actual text before the window closes.

The canopy

ANSI Z133 is now on the 2026 edition

The current revision of the arborist safety standard is Z133-2026, with updated provisions on friction-hitch materials, mechanical rope-work-positioning devices, climbing ropes and system-component compatibility (Toshi Landscape). Worth remembering why this matters: OSHA still has no dedicated federal tree-care standard and leans on general industry rules and the General Duty Clause. When an inspector needs a yardstick after an incident, Z133 is the one they reach for. Knowing the current edition is cheap insurance.

Another lawn-and-tree roll-up

Turf Masters Brands bought Turf Guys, an Illinois company doing lawn, tree and shrub care, on October 22 (Turf Masters via WN.com). It's the same pattern we keep flagging: regional lawn-care brands folding tree and shrub work into the portfolio to grab more of each property. If you compete in northern Illinois, your next bid is against a bigger balance sheet.

Arbor Day Foundation moves earlier into disaster response

The Arbor Day Foundation widened its post-disaster work to cover the immediate phase after wildfires, floods, hurricanes and tornadoes (Las Vegas Sun). That means hazard-tree removal, pruning, erosion control, rescue watering and health assessments before any replanting. The foundation pointed to the 2025 Los Angeles-area fires, where surviving trees needed watering and monitoring through the drought that followed. There's paid recovery work in that pipeline for crews who know how to triage a damaged canopy.

Safety report

A tree trimmer died in Bonita, California, after becoming trapped roughly 35 to 40 feet up a tree near Horton Road on October 11 (FOX 5 San Diego via Ground News). Multiple agencies responded. The available report did not name the worker, describe the entrapment mechanism, or mention OSHA involvement.

Two logging workers were injured in a wooded part of Kanawha County, West Virginia, when a tree fell on them around 2:35 p.m. on October 22 (WSAZ). The terrain made the rescue hard. Both were airlifted to hospitals. No names or injury details were released.

Also on October 22, Dustin Burke was pinned under a tree during land clearing on Monroe Road in Madison County, Alabama (WAFF 48). He had been running a skid steer and was flown out in serious but stable condition. The report named no cause and no OSHA investigation.

Pest and disease watch

EAB reaches Washington for the first time

The Washington State Department of Agriculture confirmed emerald ash borer in southeast Washington after staff found larvae and USDA verified the specimens (OPB). It's the state's first documented detection. Officials pulled the infested tree and told residents to stop planting ash. Washington already put a firewood quarantine in place earlier this year, because moving wood is how this beetle travels.

On the other coast, EAB is now confirmed in every Vermont county, with Essex the last to fall (VTDigger). Researchers expect it to kill most of the state's ash, and black ash shows almost no resistance. Foresters are injecting systemic insecticide into selected trees, with repeat injections every few years to hold the line. Two coasts, same beetle, same slow retreat.

Species spotlight

Slash pine (Pinus elliottii) is the fast, straight southern yellow pine of the Coastal Plain, native from South Carolina down through Florida and into Louisiana. It runs 60 to 100 feet tall and self-prunes to a high crown, so the climbing is often clean once you're past the lower stem. The wood is dense and strong at around 0.54 specific gravity, and it's very resinous. That resin is the catch on a rig. Cuts gum up, saw chains load with pitch, and anything that drips finds your gear and your truck. Historically the tree was tapped for turpentine and rosin, which tells you how much pitch it carries.

It grows on moist, sandy, acidic flatwoods and shrugs off seasonally wet ground, which is why you see it in plantations across the Southeast. Watch for two problems: southern pine beetle, which can move fast through stressed stands, and fusiform rust galls on stems and branches. Dormant season is the window if you're pruning.

One for the lunch break

Ninety-one climbers showed up to Tower Grove Park in St. Louis for the International Tree Climbing Competition on October 9 through 11, and EJ Turner of House Springs, Missouri, was one of them (The Leader). The aerial rescue event sends competitors up to a dummy about 25 feet off the ground and gives them five minutes to get it down safely. Turner has done four international events, including stops in Australia and Canada. Germany's James Kilpatrick took the men's division and the UK's Josephine Hedger won the women's. Good reminder that the rescue skills on display there are the same ones you hope you never need on a Tuesday.

Stay safe out there,
