Over the past year we have inventoried thousands of trees across the district to determine the health, size, and species of the trees that are growing in our local and national parks. Join us in collecting the data we need to ensure the District’s trees are healthy. Inventory events occur when leaves are on the trees.
May – October
Water, Weed & Mulch
Help Casey Trees care for vulnerable young trees and give them a leg up in becoming an important part of our growing tree canopy. Come out to water, weed and mulch trees throughout the city. These events occur in the summer months when trees need water the most.
June – September
Trees with good structure are more resistant to high winds, snow, ice, and other natural stressors. Learn effective pruning skills from the Urban Forestry Administration and Casey Trees arborists by pruning and caring for trees throughout the city.
