Who Needs Tree Assessment?

When you’re purchasing new property, or making changes to your existing property, a tree assessment can provide valuable information about the health of your trees. Learning now about how your planned projects could impact your trees saves time later. This means a smoother process for every aspect of your project: from design to permits and construction to landscaping.


Trees add value to a property and can be a big part of your investment. If you’re buying a home it is a good idea to have the trees assessed, the same way you have the home inspected. If you’re expanding your home or creating outdoor living space like a pool or patio, having the trees inspected is a good idea.

An assessment can detect if that tree next to your new pool is in danger of falling and causing injury. Alternately, a review by a qualified arborist can provide peace of mind the tree near your new addition is healthy enough to withstand storms.


Creating a plan for new construction or landscaping frequently involves incorporating trees into the plans. Designing around a tree that is unhealthy can impact future plans for the property and cause costly delays.

Austin has tree regulations in place to protect trees larger than 19″ diameter. This is governed by City Ordinance Title 25, Division 2 which requires a permit for removal of protected trees. A tree assessment report prepared by a certified arborist can help contractors get approval for an administrative variance to remove trees that are dead and diseased.

Consult an Arborist Before Working Close to Valuable Trees

Landscape and construction practices have a critical influence on the root zone. The root zone is the lifeline of a tree. Damaging or compromising it during construction can lead to the decline of the tree’s health.

If the project plans have any chance of impacting your trees, consulting with an Arborist before the project starts can save time and headache later. A tree assessment gives you information to make educated decisions about the project and how it could affect your trees. When warranted, we will discuss the trees with your contractors to prevent irreparable damage or unnecessary cost.

While conducting an initial tree inspection, the arborist is checking out four specific indicators of the tree’s health, from the soil to the top of the canopy.

Visual Inspection

The arborist looks at the trunk, limbs, branches, and the color and density of the foliage. He is performing a ground-based 360-degree inspection.

Is the tree vigorous with color typical of its species? Does this tree have dead, dying or broken branches? Are there any structural defects? Do the leaves show damage from herbicide or signs of nutrient deficiency? Is an aerial inspection needed?

Damage Detection

It is essential to assess whether the tree has cavities or decay, which can weaken its structural integrity. The arborist will look for signs of disease and insect damage. Special tools are used to test the integrity of the tree inside the trunk.

Root Flare Evaluation

Next, the arborist moves to the lower part of the trunk where it joins the roots to inspect the root flare, also known as the root collar. Trees are often planted too deeply, and mulch is placed too close to the trunk burying the root collar.

The root collar is the most sensitive part of the tree where root tissue becomes stem tissue:  stem choking roots and basal rot are a serious and common problem in urban trees.

Root Zone Review

Continuing to the ground, he will inspect the site conditions in and around the root zone, focusing on soil health and roots. Roots may extend over two times the height of the tree from the trunk.  Feeding roots and structural roots are the foundation of healthy and stable trees, so they are a significant focus of our practice.

Heritage Tree Care has extensive diagnostics capacity, including several types of soil testing which include; micro-biomass testing, bulk density testing, PH and nutrient testing and looking for herbicide damage.

After the in-depth inspection, our Arborist will prepare a thorough tree assessment report. It will explain any problems and our recommendations for treatment and remediation of conditions that will damage your tree. If your tree is showing signs of decline, we can provide root collar excavation, fertilization, and an immune-boosting drench —  among other tree care services. When soil compaction is depriving its roots of air and water, we are able to aerate and improve the soil.

If your tree is healthy, we will provide information about a maintenance program for its continued well being. Proper soil care, mulching, and pruning can provide your tree the natural resources it needs to have a long, healthy life.
