Tree Risk Assessments: What They Are and Why They Matter

April 15, 2025

Trees are a vital part of our environment, offering shade, oxygen, and beauty, but they also come with responsibilities. What happens when that towering oak by your home shows signs of decay, or the pine by your favorite park leans precariously after a storm? This is where tree risk assessments come into play.

This blog will explore what tree risk assessments are, why they matter, and how they can save you from property damage, injury, and unnecessary tree removal. Whether you’re a property owner, an arborist, or simply tree-curious, this guide will answer your questions.

What Is a Tree Risk Assessment?

A tree risk assessment is a detailed inspection performed by a certified arborist to determine the structural health and potential risks associated with a tree. The aim is to identify whether a tree poses a threat to people, property, or surrounding vegetation and to recommend appropriate action. Think of it as a health check-up but for a tree.

Key Elements of a Tree Risk Assessment

When performing an assessment, arborists typically evaluate three major factors:

Tree Health

This involves examining the tree for visible signs of diseases, pests, decay, cracks, or weak branches. Healthy trees are less likely to fail, but even minor ailments, if left untreated, can weaken the structural integrity.

Environment

The surrounding environment plays a critical role. Factors like poor soil quality, overcrowding, or construction activities can increase a tree’s risk of failing. Weather conditions, such as heavy winds and snow, are also considered.

Targets or Potential Impact

The risk a tree poses is partly defined by what it could damage if it fell. This could include homes, power lines, vehicles, and people walking nearby. Trees in high-traffic areas naturally present a greater risk than those isolated in an open field.

Why Tree Risk Assessments Matter

Protecting People and Property

Trees are strong, but they’re not invincible. A healthy-looking tree can harbor unseen dangers such as internal decay or root rot, and these risks grow with the tree's age and size. Performing regular assessments helps reduce the chance of accidents.

For instance, a falling branch might seem like a minor risk, but in high winds, even smaller branches can cause serious injuries or damage vehicles and homes. A 2021 study showed that falling trees cause 100–200 fatalities annually in the U.S. alone. Many of these incidents could have been avoided with proactive management.

Saving Your Trees

Tree risk assessments aren't just about removing hazards; they’re also about preserving trees wherever possible. A professional arborist can pinpoint weak areas, recommend pruning methods, or apply treatments to improve health rather than opting for tree removal.

By catching issues early, you can save the tree and avoid the cost of replacement or the environmental toll of cutting it down.

Legal and Insurance Obligations

Property owners can often be held responsible for damages caused by a neglected tree. Additionally, many insurance companies require proof that trees on a property have been evaluated to reduce liability risks. Regular tree risk assessments ensure both compliance with local laws and peace of mind.

Signs You May Need a Tree Risk Assessment

It’s wise to schedule a tree risk assessment if you notice any of the following warning signs:

Leaning Trees: A sudden lean often suggests root damage.
Visible Cracks or Splits: Open wounds on the trunk or branches may weaken the structure.
Dead or Drooping Branches: These can fall easily in storms and may indicate poor health.
Fungi Growth: Mushrooms at the base often point to internal decay.
Damaged Roots: Exposed or cut roots can destabilize the entire tree.
Recent Storm Damage: Strong winds and heavy snow can weaken even healthy trees.

If any of these symptoms sound familiar, it’s better to act sooner rather than later.

The Assessment Process

Step 1. Initial Inspection

The arborist takes a walk around the tree, noting its condition, position, and surroundings. This visual inspection focuses on obvious signs of damage or decay.

Step 2. Detailed Examination

Using tools like a mallet to sound test for hollow cavities or a resistograph to measure wood density, arborists dig deeper. For underground issues, ground-penetrating radar may be used.

Step 3. Risk Categorization

Based on their findings, the arborist will classify the tree’s risk level, ranging from low to high. They’ll then provide a report with recommendations for next steps.

Step 4. Action Plan

Depending on the risk level, the arborist may recommend pruning, bracing, cabling, or selective tree removal. For larger properties or estates, a long-term management plan may also be outlined.

Who Can Perform a Tree Risk Assessment?

Tree risk assessments are best left to certified arborists, preferably those trained through organizations like the International Society of Arboriculture (ISA). These professionals have the expertise and equipment needed to assess both external and internal factors.

How Often Should You Assess Your Trees?

Residential property owners should consider scheduling an assessment every 2–5 years, especially for larger or mature trees. High-risk areas, like trees near playgrounds or overhanging busy roads, should be inspected annually or even seasonally.

Proactive Care is the Best Care

While tree risk assessments are effective at pinpointing problems, maintaining a regular tree care schedule can help prevent risks from developing in the first place. Routine care, such as mulching, watering, and seasonal pruning, keeps trees healthy and resilient.

When in Doubt, Reach Out

If you’re unsure whether your property’s trees pose a risk, consult a professional sooner rather than later. Trees are not just decorations; they play a critical role in ecosystems and our daily well-being. By prioritizing proactive care like tree risk assessments, you’re investing in safety, aesthetics, and environmental health.

Root Problems That Indicate an Unhealthy or Unstable Tree

December 19, 2025

Trees add beauty, shade, and value to your property—but when their root systems are compromised, they can quickly become a serious safety hazard. Many of the most dangerous tree problems start underground, where damage often goes unnoticed until visible symptoms appear above ground. Understanding common tree root problems can help homeowners in West Atlanta identify when a tree is unhealthy or unstable and needs professional attention. Why Tree Roots Matter More Than You Think Tree roots anchor the tree, absorb water and nutrients, and support overall growth. When roots are damaged, decaying, or restricted, the tree becomes stressed and structurally weak. In severe cases, compromised roots can lead to sudden tree failure, increasing the risk of property damage or injury—especially during storms common in the West Atlanta area. Common Root Problems That Signal Tree Trouble 1. Exposed Roots at the Surface Roots that are visible above ground can indicate soil erosion, improper planting depth, or root damage. Exposed roots are vulnerable to physical injury, temperature extremes, and disease. They also suggest the tree may be losing its ability to anchor itself securely. Why it matters: Trees with exposed roots are more likely to lean, decline in health, or topple during high winds. 2. Girdling Roots Girdling roots grow in a circular pattern around the base of the trunk, slowly strangling the tree by restricting the flow of water and nutrients. Warning signs include: Thinning canopy Slow growth Dieback in branches Trunk swelling near the base This issue is especially common in trees planted too deeply or in compacted soil. 3. Root Rot and Fungal Decay Root rot is often caused by poor drainage or consistently wet soil. Fungal pathogens attack the roots, weakening their structure and reducing the tree’s ability to absorb nutrients. Symptoms may include: Mushrooms or fungal growth near the base Soft, spongy roots Yellowing or wilting leaves Sudden tree decline Root rot is a serious condition that can lead to unexpected tree failure if left untreated. 4. Soil Compaction Around the Root Zone Heavy foot traffic, vehicles, or construction activity can compact soil, limiting oxygen and water flow to the roots. Effects of soil compaction: Stunted growth Sparse foliage Increased susceptibility to pests and disease Compacted soil prevents roots from expanding properly and can slowly suffocate the tree. 5. Severed or Damaged Roots Construction projects, trenching, or improper landscaping can cut or crush major roots without immediate visible effects. Long-term risks include: Reduced stability Increased likelihood of falling Decline in overall tree health Even cutting a portion of the root system can destabilize mature trees. 6. Leaning Trees with Soil Heaving If you notice a tree suddenly leaning or soil lifting on one side of the trunk, this is a strong indicator of root failure. This is an urgent warning sign that the tree may be at risk of falling and should be inspected by a professional immediately. When to Call a Professional Tree Service Root problems are not always visible, and diagnosing them accurately requires experience and proper evaluation. If you notice any of these warning signs, it’s important to act quickly. A professional tree inspection can determine whether the tree can be saved or if removal is the safest option.

Preventing Plant Invasions: Smart Landscaping Choices for Homeowners

December 11, 2025

Invasive plants can quietly take over a yard, overwhelm native species, and disrupt the health of your landscape. While some invasive plants look attractive at first, they often spread aggressively—stealing nutrients, blocking sunlight, and creating long-term maintenance challenges for homeowners. By making smart landscaping choices from the start, you can protect your property and preserve the natural balance of West Atlanta’s environment. At West Atlanta Tree Service, we help homeowners maintain healthy, sustainable landscapes. Here’s how you can prevent plant invasions and make better planting decisions. What Makes a Plant Invasive? An invasive plant is any non-native species that spreads rapidly and causes ecological or structural harm. These plants often: Grow faster than native species Produce an excessive number of seeds Spread easily through roots or runners Outcompete local plants for water, nutrients, and light In West Atlanta, common invasive species include kudzu, English ivy, Chinese privet, and wisteria—plants that can climb trees, smother shrubs, and choke out natural habitats. 1. Choose Native Plants for a Lower-Maintenance Landscape One of the easiest ways to prevent plant invasions is to landscape with native plants. These species naturally thrive in Georgia’s climate and typically require less watering, fertilizing, and pruning. Top Native Choices for West Atlanta: Southern magnolia Sweetgum Red maple Wax myrtle Black-eyed susan Georgia aster These plants grow naturally in the region and contribute to healthier soil, improved biodiversity, and a more resilient yard. 2. Avoid Popular Yet Problematic Invasive Plants Some invasive plants are still sold in stores because they grow quickly and look appealing. Unfortunately, they can spread beyond the planting area and damage nearby trees or choke out other landscaping. Plants to Avoid: English Ivy – Can climb tree trunks, weakening them. Bradford Pear – Beautiful blooms, but they spread rapidly and break easily. Bamboo – Incredibly invasive and hard to remove once established. Chinese Privet – Forms dense thickets that block sunlight. By skipping these plants, you save yourself years of costly removal and tree health issues. 3. Install Barriers to Control Aggressive Root Systems Even non-invasive plants can have aggressive roots. Species like bamboo, mint, or certain ornamental grasses can spread underground and take over your yard. Root barriers help by: Limiting lateral root growth Preventing expansion into walkways or garden beds Protecting trees from competition A tree service professional can recommend barrier types based on soil conditions and existing plantings. 4. Mulch Smartly to Stop Unwanted Spread Mulch is more than just a visual finishing touch—it’s a powerful tool for preventing invasive growth. A thick layer of mulch can: Block sunlight from weed seeds Reduce the spread of shallow-rooted invasive plants Help trees retain moisture and nutrients Use natural hardwood mulch or pine straw for best results around trees and shrubs. 5. Monitor Your Landscape Regularly Early detection is key to preventing an invasive species from establishing itself. Homeowners should: Walk their property monthly Look for fast-spreading vines, seedlings, or unusual growth patterns Remove suspicious plants while they’re small Call a professional when dealing with large or deep-rooted invasions West Atlanta Tree Service provides expert inspections to help identify early signs of plant overgrowth before they become costly problems. 6. Get Professional Help for Removal and Management Some invasions—especially ones involving ivy, privet, or bamboo—require professional removal to ensure the roots are properly handled. DIY attempts often leave fragments behind, allowing the plant to regrow quickly. A certified tree service can safely: Remove invasive vines from tree trunks Grind out root systems Repair damage caused by invasive species Replant with safe, native alternatives Protect Your Landscape with Smart Planting Decisions Preventing plant invasions is one of the best long-term investments you can make for your property. By choosing native plants, avoiding aggressive species, and monitoring your yard regularly, you can enjoy a healthier, more beautiful landscape. If invasive plants are already impacting your property, West Atlanta Tree Service is here to help. Our team specializes in tree health, invasive removal, and landscape preservation—ensuring your yard stays safe and thriving for years to come.

Root Trouble: Signs Your Tree May Be Unstable or Unhealthy

December 4, 2025

Healthy roots are the foundation of a strong, stable tree. When those roots become damaged, compacted, or diseased, the entire tree is at risk—sometimes without you realizing it. For homeowners in West Atlanta, keeping an eye on early warning signs can prevent property damage, costly removals, and dangerous accidents. If you suspect your tree may be in trouble, here are the key signs to look for and why calling a professional tree expert is the safest next step. 1. Visible Root Damage or Decay Roots should be firm and well-anchored. When they’re compromised, the danger increases quickly. Common signs include: Soft, spongy, or crumbling roots Fungal growth (like mushrooms or conks) around the base Strong, foul odors indicating rot Exposed roots that appear brittle or dry Root rot often develops silently, but visible decay almost always means the issue is advanced. 2. Soil Heaving or Cracked Ground If the soil around your tree appears lifted or cracked, especially after strong winds or heavy rainfall, it’s a sign the roots may be losing their grip. You may notice: Soil pushed upward on one side of the trunk Gaps forming between the soil and the base Sudden leaning after the ground shifts Soil movement is one of the earliest indicators that a tree is becoming unstable. 3. A Sudden or Increasing Lean A gentle lean that a tree has had for years is usually harmless. But a new or worsening lean often points to root damage, soil failure, or structural decline. Warning signs include: Leaning accompanied by cracked soil Leaning after storms Branches suddenly shifting direction toward the ground Tilted root plate (where the trunk meets the soil) A leaning tree should always be evaluated quickly for safety. 4. Sparse Foliage and Slow Growth When roots can’t absorb nutrients, the canopy tells the story. Look for: Thinning leaves Dead or bare branches Leaves that are unusually small or pale Delayed leaf-out in spring Declining growth from year to year These symptoms suggest the roots aren’t supplying enough water or nutrients to keep the tree healthy. 5. Cracks or Splits Near the Base of the Trunk The lower trunk is closely connected to the root system. Damage here can reveal deeper issues. Signs of concern include: Vertical splits Missing bark Soft or hollow areas Deep cracks during dry seasons Insect activity around damaged sections These issues can reduce structural stability, making the tree more vulnerable to falling. 6. Fungal Growth Around the Base Fungi thrive in decaying wood and are one of the strongest indicators of internal root problems. Common fungal warning signs: Mushrooms forming around the soil line Shelf-like growths attached to the base Dark, wet-looking patches on the trunk Wood that crumbles under pressure If fungi are growing, decay is already underway—and often extensive. 7. Branch Dieback Starting from the Top The top of the tree—called the crown—shows stress first when roots fail. Watch for: Dead branches near the upper canopy Sudden twig drop Bare patches where leaves once flourished Visible decline spreading downward This pattern usually means the root system is compromised and can no longer support full canopy growth. Why Root Problems Should Never Be Ignored Unstable or diseased roots can lead to: Tree collapse or breakage Property damage Injury to people and pets Loss of landscape value Insect and disease spread to nearby trees Early intervention is the best protection. Many root-related issues can be managed—or stopped—when detected soon enough.
