What Does a Certified Arborist Look for Before Approving Tree Removal? Insights from a Tree Removal Contractor in Buffalo Grove, Illinois

A certified arborist in Illinois does not usually have legal authority to approve tree removal. But they absolutely influence the decision. Think of them as the professional voice of reason in the process. Their job is to decide whether removal is justified on safety and health grounds.

Below, this tree removal contractor in Buffalo Grove, Illinois is going to explain how that decision is made, and what arborists check before recommending tree removal on your property.

Is tree removal allowed and who controls it?

Many Illinois communities (including Highland Park) restrict the removal of trees over a certain size. In other words, you can’t remove the tree even if it is on your own property. These rules protect urban tree canopies and verify that you, as a property owner, handle removals responsibly.

An experienced tree removal contractor in Buffalo Grove, Illinois will always start by confirming whether the tree is on your private property or public land. Ownership is important because it directly affects who has the final say.

From there, they review local regulations to see if the tree’s size or species triggers special requirements. After they sort that out, they explain exactly which permits or approvals you need to proceed.

Is the tree healthy or beyond recovery?

The arborist evaluates whether your tree is showing signs of serious stress. If the tree shows decline, they identify the cause. This may include pest infestations, fungal diseases, soil compaction, root system damage, etc.

Healthy trees typically have consistent leaf growth and strong bud development. On the other hand, thin foliage or dead branches can be signs of deeper issues that arborists cannot easily reverse.

The arborist studies the canopy structure and overall branch growth pattern. They look for visible signs of disease or weather- or construction-related damage. They then determine whether the condition can be treated. If recovery looks unlikely, arborists may recommend removal as the best option.

Does the tree have structural defects?

Structural problems are one of the most common reasons arborists flag a tree for removal. This risk increases when the tree is near your home or other public areas. Even a tree that looks healthy on the outside can have hidden structural weaknesses.

Arborists use established tree risk assessment practices to inspect your tree from top to bottom. They look for cracks in the trunk and weak branch attachments. They look for external signs of internal decay or leaning that suggest instability. They also examine the root system and trunk base for signs of root damage.

If those defects point to a high risk of failure, especially during storms or high winds, arborists recommend removal.

What is the risk to people and property?

Tree risk depends on both the tree’s physical condition and its surrounding environment. A defective tree poses greater danger when people or structures are within its potential fall zone.

Arborists consider how likely your tree (or a major limb) is to fail and what the consequences would be if it did. If pruning or other mitigation methods can’t reduce the risk to an acceptable level, arborists choose to remove the tree.

Can the problem be solved without removal?

Arborists rarely consider removal as the first option when addressing tree problems on your property. A qualified tree removal contractor in Buffalo Grove, Illinois will look for less invasive alternatives first. Professional arborists prioritize preserving mature trees whenever safety allows.

They may recommend targeted pruning to reduce weight or installing support systems like cables or braces to stabilize weak limbs. They may suggest soil improvement or pest management. Full removal makes sense only when these measures can’t effectively manage the risk.
