Why Tree Risk Assessments Are Essential for Property Owners in the Midwest

May 21, 2025

From Asset to Liability

In the heart of the American Midwest, trees are more than just part of the landscape—they are essential components of residential, commercial, and agricultural environments. Mature specimens like the white oak, sugar maple, and American elm offer beauty, shade, and property value. But without proper oversight, these same trees can become liabilities. Tree risk assessments are not optional—they are essential for responsible property management.

What Is a Tree Risk Assessment?

A tree risk assessment is a systematic evaluation performed by a certified arborist to determine the likelihood of a tree—or part of a tree—failing and causing damage or injury. These assessments are guided by industry standards set forth by the International Society of Arboriculture (ISA), and they are a core service offered by Midwest Tree Surgeons.



The process includes an inspection of the tree’s structural integrity, overall health, species-specific behavior, and environmental factors like soil condition and wind exposure. Arborists then classify the risk level and offer tailored recommendations—ranging from minor pruning to full removal.

Why Midwestern Property Owners Need Them

In the Midwest, the tree population includes many large, long-lived species. While this is a benefit for biodiversity and aesthetics, it also introduces structural challenges—especially as trees age. Native species like the bur oak or eastern cottonwood are known for their towering size, but they are also vulnerable to windthrow, internal rot, and storm damage.


The Midwest experiences a broad spectrum of weather conditions, from ice storms in Illinois to tornados in Missouri and prolonged droughts in parts of Iowa and Indiana. These conditions place additional stress on even healthy trees. A single windstorm can take down a limb from a seemingly strong hackberry or silver maple, potentially damaging a home, power line, or vehicle.



Tree risk assessments identify such vulnerabilities in advance—before the damage occurs.

Real Risk, Real Liability

Many homeowners assume their trees are stable simply because they have “been there forever.” Unfortunately, age does not equal strength. Internal decay, root girdling, insect infestations, and fungal infections often remain invisible to the untrained eye. Trees may still leaf out and appear healthy while hollow on the inside.



If a tree falls and causes damage—and it is determined that the hazard was foreseeable—property owners can be held legally and financially responsible. A tree risk assessment, especially one performed by a certified arborist, is often considered due diligence in both insurance and legal contexts.

What Assessments Look For

When Midwest Tree Surgeons performs a tree risk assessment, we evaluate the following:


  • Root and trunk stability: Signs of decay, cracks, or previous failure points.
  • Branch structure: Weak unions, excessive weight, or previous storm damage.
  • Species behavior: Some trees, like the fast-growing boxelder, are naturally prone to limb drop.
  • Environmental context: Proximity to structures, foot traffic, utilities, or drainage issues.
  • Pest and disease presence: Emerald ash borer, anthracnose, or fungal rot common in local species.



Using tools such as resistographs and soil probes—combined with visual inspection—we deliver a detailed report with our findings and recommendations.

Preventive Care Saves Money

A comprehensive assessment may recommend something as simple as targeted pruning to reduce weight on a large limb of a red oak, or cabling to support a split-trunk linden. These low-cost interventions can prevent high-cost outcomes like emergency removals, property repairs, or lawsuits.



For trees that pose a severe threat, removal may be necessary. In such cases, early identification ensures a safe, controlled removal under proper conditions—not a rushed response during a storm cleanup.

When insects begin damaging a tree, the first instinct may be to treat the problem as quickly as possible. But not every insect requires the same response, and some insects that look harmful may not be the actual cause of the decline. Applying the wrong treatment can waste time, money, and potentially put additional stress on the tree.  Midwest Tree Surgeons takes a diagnosis-first approach to tree care. Correct pest identification helps determine whether treatment is needed, which method is appropriate, and whether the real problem may involve disease, environmental stress, or another underlying issue.

Trees often show signs of trouble long before they experience major decline. One warning sign that deserves attention is the appearance of a canker—a localized area of dead or damaged bark that develops on a trunk, branch, or stem. Cankers can be caused by fungi, bacteria, environmental injury, or a combination of stress factors, and they often reveal that a tree is struggling to defend itself.  While not every canker means a tree is doomed, these lesions can provide valuable clues about underlying health problems. Midwest Tree Surgeons helps property owners evaluate symptoms such as bark damage, dieback, discoloration, and structural weakness so that appropriate care can begin before problems become more severe.

Pine trees are valued throughout the Midwest for their year-round beauty, wind protection, and ecological importance. Although these evergreens are generally hardy, they can become vulnerable to insect pests when stressed by drought, storm damage, construction activity, or disease. One group of insects that deserves particular attention is the pine bark beetle . While these beetles are small, their activity can have significant consequences for individual trees and, in some situations, entire stands of pines.  Recognizing the early signs of bark beetle activity allows property owners to respond before damage becomes more extensive. Professional evaluation is often the best way to determine whether a tree can be preserved or whether additional management measures are appropriate.

Standing beneath a towering oak or sycamore, it is easy to appreciate a tree’s size. What is less obvious is its age. Many of the mature trees found throughout Missouri and the greater American Midwest have been growing for generations, quietly enduring changing weather, shifting landscapes, and the passage of time. While no tree lives forever, some species possess remarkable longevity, allowing them to become living landmarks that connect communities with their natural history.  Understanding why certain trees live for centuries can help property owners appreciate the importance of proper tree care and preservation.

Pruning is one of the most valuable services a professional arborist can provide, yet it is often misunderstood. Some homeowners worry that removing healthy branches may harm a tree, while others assume pruning is only necessary when limbs become hazardous. In reality, proper pruning is a proactive practice that supports tree health, improves structure, and helps trees adapt to changing environmental conditions.  When performed correctly and at the appropriate time, pruning works with a tree’s natural biological processes, allowing it to continue growing safely and efficiently for years to come.

Trees are among the longest-living features on any property. A mature oak, maple, or other established tree may take decades to reach its full size, providing shade, beauty, wildlife habitat , and increased property value along the way. Because of the time and environmental benefits they represent, preserving healthy trees whenever possible is often a worthwhile investment.  Professional arborists play an important role in helping trees remain healthy, structurally sound, and capable of thriving for many years. Through regular evaluations and proactive care, they can identify potential problems early and recommend treatments that support long-term tree health.

Trees do much more than provide shade and enhance the beauty of a landscape. They are living ecosystems that support a remarkable variety of wildlife throughout every season. From nesting birds in the spring to sheltering mammals during the winter, healthy trees provide food, protection, and habitat for countless species.  For homeowners and property managers , understanding the connection between trees and wildlife offers another reason to invest in professional tree care. Proper maintenance not only helps preserve the health and appearance of trees but also supports the many forms of life that depend on them.

Trees add beauty, shade, and value to residential and commercial properties, but like any living organism, they change over time. While many trees remain healthy for decades, others may develop structural weaknesses that increase the likelihood of branch failure or even complete tree failure.  Identifying these concerns is not always straightforward. A tree may appear healthy on the outside while hiding internal defects, or it may display subtle warning signs that only a trained professional can recognize. That is why professional tree risk assessments are an important part of responsible property management. Certified arborists evaluate much more than whether a tree looks healthy. Their goal is to determine how likely a tree is to fail, what the consequences of that failure could be, and whether any corrective action is appropriate.

When planning a landscape, homeowners often focus on appearance, growth rate, shade potential, or seasonal color. While these factors certainly matter, another important consideration is whether a tree is native to the region.  Native trees have evolved alongside local soils, weather conditions, wildlife, and ecosystems for thousands of years. As a result, they often play a critical role in maintaining healthy landscapes and supporting the natural environment. Although non-native species can sometimes thrive in residential settings, native trees continue to provide unique benefits that make them valuable additions to properties and communities alike. Understanding why native trees remain important can help property owners make informed decisions about their landscapes.

Summer brings plenty of activity to the landscape , but not all of it is beneficial. While homeowners often focus on watering, mowing, and maintaining their outdoor spaces during the warmer months, another seasonal visitor can create significant problems for trees and plants: the Japanese beetle.  Japanese beetles are among the most recognizable insect pests found throughout much of the Midwest. Their metallic green bodies and copper-colored wings make them easy to identify, but the damage they leave behind is often what attracts the most attention. During peak summer months, large populations of these insects can feed on a variety of trees and ornamental plants, affecting both appearance and overall plant health. Understanding how Japanese beetles impact trees can help homeowners recognize potential problems and determine when professional assistance may be beneficial.
