ISA Certified Arborist in Santa Rosa, CA

ISA Certified Arborist Help for Trees That Need a Closer Look

SRT Forestry provides ISA certified arborist service in Santa Rosa, CA for property owners who need help understanding a tree’s condition before deciding what to do next. This is useful when a tree is leaning, dropping limbs, declining, showing disease symptoms, or growing too close to a home, driveway, fence, or utility area.

An ISA certified arborist can help separate a tree that needs care from a tree that may be unsafe. Sometimes the right answer is tree pruning, tree cabling and bracing, or tree preservation. Other times, the safest answer may be hazardous tree removal.

  • Tree health and structure evaluations
  • Risk concerns for leaning, cracked, or damaged trees
  • Oak tree, root zone, and site condition review
  • Practical recommendations before tree work begins

Based in Santa Rosa, we serve Sonoma County and nearby North Bay communities. Check coverage for your property.

When to Call an ISA Certified Arborist

Some tree problems are easy to see. Others are hidden in the canopy, trunk, roots, or site conditions. Arborist work helps connect the visible symptoms with the likely cause.

  • Tree Risk Concerns

    If a tree is leaning, cracked, storm-damaged, or close to a structure, a tree risk assessment can help decide the safest next step.

  • Tree Health Problems

    Thinning leaves, dieback, fungus, bark damage, and early leaf drop may need tree diagnosis or tree disease diagnosis.

  • Mature Tree Preservation

    Large, older trees often deserve a careful look before removal. We help with preservation options when the tree is still worth saving.

  • Root Zone Issues

    Compacted soil, grade changes, trenching, and irrigation problems can stress roots. In those cases, root management may be needed.

  • Oak Tree Care

    Santa Rosa and Sonoma County have many valuable oaks. Our oak tree care service helps with pruning timing, deadwood, roots, and health concerns.

  • Before Major Tree Work

    Before removal, heavy pruning, crown work, or construction near trees, arborist guidance can help protect the property and the tree.

We Look at the Tree, the Roots, and the Site Around It

A tree problem is not always caused by one thing. It can come from old pruning cuts, soil compaction, root damage, poor drainage, drought stress, pests, disease, storm damage, or a structure being too close to the tree.

That is why an arborist evaluation should look beyond the branch that is bothering you. We look at the canopy, trunk, root flare, surrounding soil, nearby hardscape, slope, irrigation, and what could happen if the tree fails.

  • Canopy review: Deadwood, thinning, dieback, weak limbs, and branch spacing.
  • Trunk review: Cracks, cavities, fungus, wounds, included bark, and decay signs.
  • Root review: Exposed roots, compaction, grade changes, girdling roots, and damage.
  • Site review: Homes, fences, driveways, slope, access, fire exposure, and target areas.

ISA Certified Arborist
questions

Need to discuss your particular tree or property? Get in touch.

What does an ISA certified arborist do?

An ISA certified arborist evaluates tree health, structure, risk, and care needs. They help property owners make better decisions about pruning, preservation, removal, and tree safety.

When should I call an arborist instead of a tree crew?

Call an arborist when you are unsure what is wrong with a tree, whether it can be saved, whether it is risky, or what type of work should be done.

Can an arborist tell me if a tree needs removal?

Yes. If the tree has serious decay, structural failure, root damage, or unsafe lean, an arborist can help determine whether removal is the safest choice.

Do you help with trees near homes or driveways?

Yes. Trees near structures, driveways, fences, and high-use areas are common reasons property owners call for arborist help.
