Clackamas County is home to some of the most productive tree growing land in the world. Our native forests cover more than two-thirds of the county's land. In addition, thousands of acres of land have been planted to Christmas trees and ornamental landscape nursery trees.

John and Carol Belton's property picture compressed Tree crops and products are a mainstay of our local economy providing important jobs for residents and income for landowners and managers. In fact, nearly 20% of all personal income for Clackamas County residents comes from our trees. Growing and managing trees is a big business in Clackamas County.

The OSU Extension Forestry program provides the education and research support for tree growers in Clackamas County. Our education programs keep landowners and managers on the cutting edge of technology and provide information to assist them to imporve the productivity and profitability of their land.

Remember...Clackamas County is tree country. We look forward to serving you!


The Oregon Department of Forestry now has three Stewardship Foresters providing assistance to landowners and oversight on forest practices in Clackamas county. And there are two Stewardship Foresters for Marion County. See the map showing the staffing areas of responsibility for Stewardship Foresters in our area.
