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.

How Invasive Plant Species Threaten Native Midwest Forests

July 23, 2025
Protecting the Midwest Landscape The trees that define the Midwest landscape (oaks, maples, elms, and more) are essential to the health of local ecosystems . They provide shade, support wildlife, and help maintain soil and air quality. But these natural systems are increasingly threatened by invasive plant species that crowd out native growth and disrupt the balance of the environment. Unlike native species, invasive plants are introduced from outside ecosystems and tend to grow rapidly, reproduce aggressively, and outcompete native plants for resources. Without natural predators or environmental checks, these plants spread quickly and can overtake entire landscapes if left unmanaged. At Midwest Tree Surgeons, we help property owners and land managers identify and remove these harmful species before they do lasting damage. Understanding the problem is the first step toward protecting your trees and your land.

Why Summer Storms Can Be a Threat to Weak Trees

July 16, 2025
 How to Protect Your Property This Summer Midwestern summers are known for their beauty: long sunny days, lush greenery, and warm evenings. But they also bring a regular cycle of heavy storms. Thunderstorms, high winds, and saturated ground can wreak havoc on vulnerable trees, creating serious safety hazards and costly property damage. For homeowners and property managers, understanding how storm conditions interact with tree health is essential. The good news is that most storm-related tree failures are preventable with proactive care and inspection. This article will explore why weak trees are especially at risk during summer storms and how working with a certified arborist can help safeguard your property.

What Does It Mean to Be a Certified Arborist?

July 11, 2025
 Expert Tree Care Starts Here When it comes to tree care, not all professionals are created equal. A chainsaw and a truck do not make someone qualified to assess the health, safety, and structure of a tree. That distinction belongs to certified arborists—tree care specialists who are trained, tested, and held to rigorous professional standards. At Midwest Tree Surgeons, we take pride in providing expert tree care delivered by certified professionals. But what exactly does “certified arborist” mean? And why should it matter to homeowners and property managers? Let’s take a closer look at what this credential entails and why it’s a crucial factor in responsible, long-term tree care.

Protect Your Property with Professional Tree Care Trees can be one of the most beautiful and valuable features on your property—but they also require expert care. While most homeowners can spot a clearly dead tree or a broken limb after a storm, many of the early warning signs of trouble go unnoticed until it is too late.

At Midwest Tree Surgeons, our team includes trained professionals who understand not only the biology of trees, but also the structural, environmental, and safety risks they may pose—especially during the fast-growing summer months.

How to Know if Your Tree Is Beyond Saving

June 20, 2025
Identifying Unsalvageable Trees Trees are living organisms—resilient, beautiful, and vital to the health of any landscape. But like all living things, trees can suffer from disease, injury, and decay. Sometimes a tree can be treated or trimmed to preserve its health. Other times, it is too far gone to recover, and attempting to save it becomes more dangerous than it is worth. At Midwest Tree Surgeons, we often get called out by property owners who aren’t sure what condition their tree is in—or what to do about it. Here are some clear signs that your tree may be beyond saving, along with guidance on when to bring in a certified arborist for an expert assessment. 1. No Leaves (Outside of Dormant Season) If it’s late spring or summer and a tree is completely bare , it may be dead. Deciduous trees that lose all their leaves during the growing season—or that fail to produce new growth year after year—are likely no longer functioning.  Tip: If you scratch the bark with your fingernail and it’s dry and brown underneath instead of green, that’s a bad sign.

June 5, 2025
Thriving in the Midwest Planting a tree is a long-term investment—not just in your property, but in your environment, your home’s curb appeal , and even future shade and energy savings. But not all trees are equally suited for the Midwest’s unique climate, soil types, and seasonal swings. And even the right tree, if planted in the wrong spot, can become a problem rather than an asset. At Midwest Tree Surgeons, we are committed to helping homeowners and property managers make smart choices that result in healthy, well-placed trees that thrive for decades. If you’re thinking about planting, here’s what to know about tree selection and placement in the Midwest.
