What Is Tree Protection Zone?

A Tree Protection Zone (TPZ) is a designated area around a tree’s root system, trunk, and canopy that acts as a safeguard during construction, landscaping, or any activity that could harm the tree. By creating a physical barrier and clearly defined boundaries, TPZs help preserve tree health, structural stability, and long-term beauty.

At Kolcun Tree Care, our ISA Certified Arborists design customized Tree Protection Zones that follow industry standards and take into account each tree’s size, species, and health. This proactive measure is essential for protecting valuable trees from the hidden damage caused by soil compaction, root injury, or accidental impact.

Why Do You Need Tree Protection Zone?

It protects your most valuable trees from damage during construction or site work—ensuring they remain healthy for decades to come.

Prevent Costly Long-Term Damage

Even minor root injury during construction can lead to decline or instability years later—TPZs safeguard against that risk.

Maintain Property Value and Beauty

Mature, healthy trees enhance curb appeal and provide shade, privacy, and environmental benefits that are worth preserving.

Meet Permit and Preservation Requirements

Many municipalities require TPZs as part of approved building or renovation plans.

Tree Protection Zone FAQs

Comprehensive guidelines for safeguarding root zones and preserving tree health during residential construction or landscaping projects
  • Can a Tree Protection Zone be adjusted once it’s in place?
    While it’s best to set a TPZ before construction begins, it can be modified if project plans change. Adjustments should only be made under the guidance of an ISA Certified Arborist, who can assess how to maintain adequate root and canopy protection. They may also update residential tree pruning services or professional tree trimming recommendations to accommodate the new layout while keeping the tree safe.


  • Can a Tree Protection Zone help me comply with local building codes or HOA requirements?
    Yes. Many municipalities and homeowners’ associations require TPZs as part of their tree preservation ordinances. An ISA Certified Arborist can prepare documentation, plans, and even coordinate with local officials to ensure your TPZ meets compliance. Incorporating residential tree pruning services or professional tree trimming into the plan can further demonstrate your commitment to tree health and property safety.


  • Do newly planted trees need Tree Protection Zones?
    Yes, younger trees are often even more vulnerable to damage than mature ones because their root systems are still developing. A TPZ can help prevent stress and allow for healthy establishment. Residential tree pruning services performed by an ISA Certified Arborist may also be used to shape the young canopy for balanced growth while maintaining full protection during nearby work.


  • Do Tree Protection Zones only protect roots, or do they also safeguard the canopy?
    A TPZ is designed to protect the entire tree—roots, trunk, and canopy. Roots are especially vulnerable to soil disturbance, while the canopy can be damaged by equipment or debris. An ISA Certified Arborist may recommend professional tree trimming or residential tree pruning services before construction to remove hazardous branches and maintain balance, reducing the risk of breakage during the project.


  • How does a Tree Protection Zone help preserve my trees during home improvement projects?
    During construction or heavy landscaping, tree roots can be damaged by excavation, heavy equipment, and soil compaction. A properly planned TPZ prevents this by setting clear boundaries and protection measures, such as fencing or mulch barriers. In some cases, an ISA Certified Arborist will recommend residential tree pruning services or professional tree trimming to reduce canopy stress and protect the tree’s structural balance during the project.


  • What happens if my Tree Protection Zone is not respected during construction?
    If the TPZ is violated, tree roots may be severed, soil can become compacted, and branches or bark may be damaged—leading to long-term health decline or even tree death. These issues can also create future hazards that require costly removal. Working with an ISA Certified Arborist ensures your TPZ is monitored and that any needed residential tree pruning services or professional tree trimming are performed to mitigate damage quickly.


  • What is a Tree Protection Zone (TPZ) and why is it important for homeowners?

    A Tree Protection Zone (TPZ) is a designated area around a tree’s root system, trunk, and canopy that is safeguarded from construction, soil compaction, and other damaging activities. These zones are critical for preserving a tree’s health, stability, and longevity during home renovations or landscaping projects. An ISA Certified Arborist can help define and enforce your TPZ, sometimes in conjunction with residential tree pruning services or professional tree trimming to ensure structural safety and long-term vitality.

  • Who determines the size and boundaries of a Tree Protection Zone?
    The size and boundaries of a TPZ are typically determined by an ISA Certified Arborist, following industry standards and factoring in the tree’s species, size, age, and health. The goal is to protect both the visible parts of the tree and the unseen root system. This process often pairs with professional tree trimming or residential tree pruning services to remove dead or hazardous limbs that could pose a risk during construction.
