Introduction to the Forestry program

A lot to offer woodland owners and Christmas tree growers

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.

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 education and research support for tree growers in Clackamas County. Our education programs keep landowners and managers on the cutting edge of technology and provides information to assist them to improve productivity and profitability of their land.

We provide woodland owners and managers with objective, research-based information and educational resources to help them make informed stewardship and management decisions. We bring state and national expertise to the community through our affiliation with the OSU Forestry and Natural Resources Extension Program and the OSU College of Forestry. We work collaboratively with many community organizations that have a shared interest in our region's forests, including soil and water conservation districts, watershed councils, landowner organizations, school districts and state agencies.

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


Oregon State University has brought informal forestry and natural resource education to the citizens of Clackamas County for the past 50+ years. Good land stewardship was the focus of early Extension efforts for local landowners and continues today. Landowner recognition through the Clackamas County's Woodland Farmer of the Year award was started back in 1955 by local Extension staff. Oregon also has a  state tree farmer recognition program that has followed Clackamas County's lead since the 1960s.

Extension helped organize landowners into local associations where education and political action were the primary missions. The Clackamas County Farm Forestry Association formed in 1957 is one of the oldest woodland owner organizations in the state and includes approximately 300 members.

Earlier Extension education in forestry and natural resource management was led by county Agriculture Agents Johnny Innskeep and Clayton Wills. Both Inskeep and Wills served the county for approximately 30 years each. The first Extension Forestry Agent (a professional forester by academic training) was hired in Clackamas County in 1976. Dan Green brought a new level of expertise in forestry education programming to the county. Following Dan's departure in 1984, Mike Bondi became Extension Forestry Agent in Clackamas County and served in that position until 2011. Mike started Tree School in 1990 - a day full of practical educational programs for forest landowners, Christmas tree farmers, and natural resource professionals. It has become the largest program of its kind in the state.

Glenn Ahrens arrived in July, 2012 and is currently the Extension Forester for Clackamas, East Multnomah, Marion, and Hood River counties.
