Tree Service in Thousand Oaks, CA
Thousand Oaks is home to 50,000 to 60,000 oaks, and the city protects nearly every one. Before we prune or remove a tree, our tree service in Thousand Oaks checks whether the city must sign off first.
Tree care in Thousand Oaks
A city named for its oaks
Thousand Oaks protects every oak over 2 inches across — the trees it is named for. A 14-year-old won a naming contest in the 1920s, and voters kept the name at cityhood in 1964. Today the valley holds 50,000 to 60,000 oaks. Four kinds are native: valley oak, coast live oak, scrub oak and Palmer's oak. The largest has a trunk 12 feet across, at the Chumash Indian Museum. About a third of the city is open space. The oaks are aging, too: in 2024 the city removed six failing oaks at the Civic Arts Plaza.
Here, even a dead oak needs paperwork before it comes down.
What we handle
Deadwood, aging oaks and stumps across Thousand Oaks
Supreme Tree Experts clears deadwood, checks aging oaks and grinds stumps in Thousand Oaks, home to 50,000 or more oaks. When a heavy oak limb hangs over the roof, Thousand Oaks owners bring it to Supreme Tree Experts.
Tree Removal
We remove trees in Thousand Oaks only after checking whether any oak is involved. Every oak over 2 inches across is protected, so even a dead one needs a Type A application. Once the owner has the city's answer, we take it down in sections and haul the wood.
Tree Trimming & Pruning
Our crews prune oaks and other yard trees with clean cuts to strong limbs. Inside an oak's protected zone, any work beyond removing dead wood needs a city permit. We take out deadwood freely and flag any live cut that needs sign-off first.
Stump Grinding & Stump Removal
Stumps are ground well below the soil so the spot can take new planting or lawn. When an oak comes out under a permit, the city expects replacement under its oak preservation guidelines. A deep grind leaves room for the young trees to root.
Palm Tree Trimming & Skinning
Palm visits cover brown fronds and flower stalks, plus skinning the old frond stubs off the trunk. Summer highs in central Thousand Oaks average about 90 degrees. Booking before the heat keeps the crown clean, and our lift truck keeps spikes out of the palm.
Emergency Tree Service
We respond 24/7 when an oak limb crashes onto a roof, car or drive in Thousand Oaks. The city's oak stock is aging, and old oaks can drop heavy limbs with little warning. We clear the hazard first, then make clean cuts on what is left.
Tree Maintenance
We inspect yard trees each year for decay, weak limbs and root trouble, then prune what needs it. In 2024, testing showed six oaks at the Civic Arts Plaza were failing, and the city took them down. A yearly look helps catch that kind of decline early.
Tree Height Reduction
We reduce the height and spread of big trees by cutting limbs back to smaller side branches. Wide oak crowns often hang over roofs here, carrying heavy end-weight. Our 75-ft boom trucks let the crew lower limbs from the street where possible.
Estate Tree Care
We manage trees on larger estates with a care plan that logs each oak and landmark tree. On lots of two acres or more, big California sycamores, bay laurels and toyons count as landmark trees. We track them with the oaks so none gets missed.
Tree Shaping & Shrub Shearing
Hand pruning and shearing keep shrubs and hedges to a clean face, full down to the base. Scrub oak can look like a shrub, but it is a native oak, protected over 2 inches across. We check before cutting any bush that might be one.
Landscaping
We design and plant Thousand Oaks yards with drought-wise plants and beds kept off oak roots. An oak's protected zone reaches 5 feet past the canopy or 15 feet from the trunk, whichever is greater. New beds and irrigation go outside that line.
Hardscape
We build patios, walks and walls that fit the slopes and knolls around your home. Building or grading near an oak's canopy calls for an Oak/Landmark Tree Permit, applied for by the owner. We lay out the design to stay clear of roots wherever we can.

A large protected tree that is not an oak. The list is larger California sycamores, black walnuts, bay laurels and toyons. The landmark rules do not apply to single-family lots under two acres, so most yards are covered only by the oak rules.
Only with a permit inside its protected zone. That zone reaches 5 feet past the canopy or 15 feet from the trunk, whichever is greater. Any work there that touches the tree or the soil needs a permit, except removing dead wood. For building or grading near the canopy, the owner applies for an Oak/Landmark Tree Permit.
The city. Trees in medians, parkways and easements fall under the city's Forestry Master Plan. Your parkway tree is the city's to prune and remove. To report a hazard or problem with a tree on a public street, submit a service request or call Public Works at (805) 449-2499.
