March 11th, a brief but strong storm came through Goodlettsville and blew over two giant trees in my front yard; one which was being supported by a 3rd tree that was facing and threatening my house. It was an…

Why Los Angeles
Why Los Angeles trees need a real arborist.
The Certified Arborist Tree Service brings expert arborist judgment, not just crews with chainsaws, to tree work across Los Angeles County, because the city's mature oak canopy and its imported ornamentals fail in different ways and need different judgment.
Los Angeles runs a Mediterranean climate: mild wet winters, long dry summers, and soil that swings from sandy coastal fill to heavy adobe clay depending on which side of the basin you're standing on. A tree that thrives on a Westside sand lot can struggle on clay a few miles inland, and vice versa.
The regional threats compound that variability. Oak root fungus targets the native coast live oaks that anchor so many older neighborhoods, polyphagous shot hole borer works through backyard maples and sycamores alike, and gold-spotted oak borer, found in parts of northern Los Angeles County, is worth watching on those same oaks. We read the species and the site before we ever start a saw.
Why Los Angeles trees fail
The risks we watch in Los Angeles right now.
These are the problems behind tree failures and canopy loss across the Los Angeles basin.
Oak Root Fungus
Armillaria root rot quietly kills coast live oaks where lawns and sprinklers keep the root zone wet. Los Angeles oaks in shaded, irrigated yards are most exposed. We check the root collar and trunk base for decay when we inspect an oak.
Polyphagous Shot Hole Borer
A tiny beetle that farms fungus inside dozens of Los Angeles tree species, from box elder to sycamore. Once a tree is heavily infested, removal is usually the only option, so early detection matters more than almost anything else we do.
Winter Storm Uprooting
Los Angeles soil dries hard for most of the year, then a wet winter saturates it fast. Shallow rooted trees, especially eucalyptus, can go over in saturated ground even without much wind. We flag lean and root plate movement before the rains hit.
Gold-Spotted Oak Borer Watch
Found in parts of northern Los Angeles County, this invasive beetle bores into oak bark and cuts off the tree's ability to move water, often with no outward sign until the canopy is already thinning. It's worth watching on older coast live oaks.

The Los Angeles species list, and what to watch for.
Local soil, local weather, local pests. Each species here fails in its own way, and we plan around all of them.
Coast Live Oak
The backbone of Los Angeles's native canopy and the species most exposed to oak root fungus, with gold-spotted oak borer, found in parts of northern Los Angeles County, worth watching too; we inspect these trees closely and rarely recommend removal if the crown still reads healthy.
Jacaranda
A Los Angeles street tree icon whose brittle wood and shallow roots mean storm damage and sidewalk lift are the recurring issues, not disease.
London Plane
Planted heavily along Los Angeles boulevards for shade; it tolerates the clay pockets well but needs structural pruning early to avoid included bark and weak unions later.
Chinese Elm
Common in older Los Angeles yards and tolerant of drought, but prone to deadwood buildup that we clear out before it becomes a liability over a driveway or roof.
Eucalyptus
Fast growing and common across Los Angeles hillsides, but shallow rooted and a known uprooting risk in saturated winter soil, plus a host for eucalyptus longhorned borer.
Crape Myrtle
A reliable smaller ornamental in Los Angeles yards; its main issue here is over pruning by unlicensed crews, which we correct with a proper structural approach.
Local expertise
Why an Expert Arborist Matters in Los Angeles
Los Angeles grows two cities' worth of trees: the native oaks of the foothills and canyons, and the imported palette of jacaranda, eucalyptus, and London plane planted over the last century. They fail differently, and a crew that only knows one side of that equation is guessing on the other.
Estimates are walked by an experienced arborist. Cuts follow ANSI A300, risk assessments follow TRAQ methodology, and you get a written plan before work begins.
Across Los Angeles County
Every community in our coverage list, from the Westside beach cities to the canyons pushing into Ventura County, has its own page covering the species, soil, and storm exposure specific to that ground.
Los Angeles FAQ
Local questions, local answers.
Don't see your question? Call us. Calls are answered by a real person, day or night.
Do I need a permit to remove a tree in Los Angeles?
Often, yes, especially for protected native trees such as oaks. Requirements vary by exact address and zoning. We confirm what applies to your property and handle any permit or arborist report needed before work begins.
How fast can an arborist get to my property?
Most estimate visits happen within 24 hours across Los Angeles County, and storm emergencies get a crew on site the same day. We answer the phone around the clock.
What is stressing Los Angeles trees right now?
Oak root fungus on the native oaks, polyphagous shot hole borer across a wide range of species, saturated-soil uprooting whenever a wet winter follows a dry summer, and gold-spotted oak borer, which has reached parts of northern Los Angeles County and is worth watching on older coast live oaks.
My eucalyptus is leaning after rain. Is that an emergency?
Treat it as one. Eucalyptus root systems are shallow, and lean after saturated soil is one of the clearest uprooting warning signs. Call before the next storm, not after it falls.
What standards do your arborists follow?
Our crews are trained to ANSI A300 pruning standards, and risk assessments follow TRAQ methodology. An expert arborist walks the estimate.
Are you insured?
Yes. We carry the insurance that matters, the kind that protects every inch of your property.
