ISA Certified Arborist & Tree Service in Wilmette, IL

​

Wilmette manages nearly 18,000 parkway trees and has earned Tree City USA status for over 39 consecutive years plus Arbor Day Foundation Sterling Community recognition. The village's tree preservation ordinance is among the most comprehensive on the North Shore, with a 6-inch DBH permit threshold that protects almost any tree of meaningful size on private property. Oaks and hickories over 10 inches DBH and any tree over 20 inches DBH are Heritage Trees with additional protections.

​

Prairie Tree Care provides ISA Certified Arborist services to Wilmette homeowners, bringing the expertise that one of Illinois' most tree-conscious communities deserves.

​

Tree Challenges in Wilmette

​

Mature canopy from grand oaks west of Green Bay Road to salt-stressed trees along Sheridan Road. The village's proactive parkway management keeps public trees healthy, but private property trees often go years between professional assessments. Construction — renovations, additions, teardown-rebuilds — is the biggest threat to private trees, which is why the village's strict protection

requirements exist.

​

Wilmette's Tree Ordinance

​

Tree Removal Permit required for any tree 6 inches DBH or greater on private property. Heritage Trees (oaks and hickories over 10 inches DBH, any tree over 20 inches DBH) may require a Zoning Board of Appeals variation. During construction, tree protection fencing required at 1 foot of radius per inch of trunk diameter. Entire parkway must be fenced even without parkway trees present. Village Forester reviews all removal applications on-site. Replacement planting required when healthy trees are removed.

​

We navigate these regulations as routine service.

Tree Removal in Wilmette

​

Wilmette's 6-inch DBH permit threshold means almost any mature tree on your property requires village authorization before removal. Oaks and hickories over 10 inches and any tree over 20 inches are Heritage Trees that may need a Zoning Board of Appeals variation — an additional review step beyond the standard permit. The Village Forester reviews every removal application on-site, and replacement planting is required when healthy trees are removed. We prepare the required documentation, coordinate the Village Forester site visit, and guide you through the Heritage Tree process when applicable. When removal is warranted, we execute with the care that Wilmette's nearly 18,000-tree urban canopy deserves.

Tree Pruning in Wilmette

​

Wilmette's 39+ years as a Tree City USA community and Sterling Community recognition reflect a village that holds its trees to a high standard. We match that standard with ANSI A300 pruning — every cut purposeful, every objective defined before work begins. For mature trees west of Green Bay Road, pruning focuses on structural integrity and risk reduction. For salt-stressed trees along Sheridan Road and near Lake Michigan, pruning reduces canopy load while PHC treatments address root zone damage. During construction projects, we provide pruning within Wilmette's strict tree protection fencing zones to maintain clearance without compromising the trees being preserved.

Frequently Asked Questions — Wilmette

​

What trees are protected in Wilmette?

Any tree 6 inches DBH or greater on private property requires a removal permit. Oaks and hickories over 10 inches DBH are Heritage Trees, as is any tree over 20 inches DBH regardless of species. Heritage Trees face additional scrutiny and may require a Zoning Board variation. This low threshold means almost every mature tree on your property is protected.

​

We're adding a pool in Wilmette. Will we need a tree survey?

Almost certainly. Any construction activity impacting trees triggers Wilmette's protection requirements. The village requires fencing at 1 foot of radius per inch of trunk diameter around every tree in the work zone, and the entire parkway must be fenced even without parkway trees. A certified arborist tree survey is the first step.

​

How is Wilmette's tree ordinance different from neighboring communities?

Wilmette's 6-inch DBH threshold is lower than most — Winnetka requires 8 inches, and many communities only regulate parkway trees. Wilmette also separately classifies oaks and hickories as Heritage Trees at 10 inches, adding extra protection for ecologically important species.
