Welcome to the OSU Extension Service

Crook County

"Education that works for you."

The OSU/Crook County Extension Service, located in the city of Prineville, has provided research-based, informal educational programs to the citizens of Crook County since 1914. This is done through coordinating educational tours, conferences, short courses, workshops and demonstrations.  We also provide brochures, publications, and research based information on a variety of subjects both in the office, over the phone, in the field, and on line.

Extension staff in Crook County along with regional Extension Staff and volunteers, offer programs and assistance in 4-H & Youth Development, Agriculture & Natural Resources, Family & Community Health, Forestry & Natural Resources, Livestock, Marine/Fisheries, Range & Natural Resources and Small Farms/Small Acreage.

Volunteer Opportunties

The Oregon State University Extension Service is the largest grassroots educational organization in Oregon. In 2010, OSU Extension trained 18,000 volunteers.

Volunteers help us educate every community and neighborhood in Oregon; they add greatly to the effectiveness of OSU Extension Service programs and allow us to expand our program outreach.

Master level volunteers are trained by university experts and in turn dedicate their time to teaching and enriching their communities. Master-level volunteer opportunities include:

  • 4-H Youth Development Program: Help youth pursue service learning projects while they develop skills in science, technology, business, communication, citizenship, and other areas.
  • Climate Masters: Help Oregonians reduce their personal energy costs and carbon footprints.
  • Family and Community Education (FCE): Promote healthy communities, families and individuals by providing education about aging well, healthy eating, and food preservation.
  • Family Food Education (FFE) (previously known as Master Food Preservers): Demonstrate safe methods of harvesting, canning, and preserving food from fresh local ingredients.
  • Master Composters or Recyclers: Lead service projects that promote waste reduction in your community.
  • Master Gardeners™: Provide expert gardening advice to the public and lead the development of sustainable community landscapes.
  • Master Naturalist: Provides an opportunity to learn about natural resources through the study of scientifically sound information: the natural history of plants, animals, habitats, and geology, the history and processes of landscape change, as well as the most relevant topics in present-day sustainable natural resource management. Participants volunteer for natural resources programs, agencies, organizations, and other groups in their communities.
  • Master Watershed Steward: Lead service projects to maintain green streets, watersheds, and parks and coordinate wetland restoration projects.
  • Master Woodland Managers: Teach Oregonians to manage woodlands and create sustainable forests for the future.

In addition, there are many opportunities to volunteer at educational events, workshops and on advisory boards in your area.
Please call us for more information and to find out when the next traings will be held.  We look forward to hearing from you!
