News & Announcements

Welcome to the new OSU Extension website

OSU Extension has been serving Oregon for more than 100 years, and our previous website launched in 2011. It was time for an upgrade! Click the title of this announcement to read more about the upgrade and share your feedback.

Welcome

The Extension Service is here to serve the residents of Columbia County, providing knowledge from universities nationwide. We provide research-based information to families, youths, schools, agricultural producers, home gardeners, foresters and governments.

Our office offers a variety of programs, which include 4-H Youth Development, Home Gardening, Agriculture and Small Farms, Family and Community Health, Forestry & Natural Resources and Master Gardeners.

We publish two newsletters from our office:

  • Country Living (gardening and farming topics)
  • Tall Timber Topics (forestry/wood lots)

If you would like to receive these newsletters by email or mail, please give the office a call.

We offer classes, workshops, opportunities for youth and adult volunteer activities:

Volunteer as a Master Gardener, Master Woodland Manager, or with the 4-H youth program

Nutrition education events

Home Garden educational events
