The City of Grand Junction's Urban Forestry program is dedicated to the protection and resiliency of Grand Junction's urban forest through the planting and management of trees in parks, city facilities, and along street rights-of-ways within city limits. Our goal is to help the community understand the importance of trees and the environmental services they provide while maintaining our city's Urban Forest.

Why Should You Root for Your Ash?

You are highly likely to have an ash tree on your property. Your tree provides shade, saves you money on utility bills, conserves water, and increases your property value. The biggest reason…treatment is tremendously cheaper than removing a dead tree. Tree removals can cost thousands of dollars. Treatment can last up to three years! Let's save your tree together!

What's up with Ash Trees?

Grand Junction Ash Trees are threatened by exceptional droughts and increasing pressures from insects, including the Lilac Ash Borer and Ash Bark Beatle. Nearly 20% of Grand Junction trees are Ash Trees. They need our support so we can continue enjoying their benefits. Luckily, we have a solution! The below image is a good representation of a declining ash tree. Does this tree look familiar?
