Living History

Each spring and fall, the Living History Village is available for school field trips. Costumed living history interpreters lead school-age students through a historical adventure, emphasizing relationships between people, the environment, and the past. Or, we can bring history to you with a Traveling Trunk Show! Learn more about the Living History program here.

About the Orchards 

Dorris Ranch is recognized as the first commercial filbert orchard in the United States and is listed on the National Register of Historic Places.

Oregon's history with filberts started in 1892 when George Dorris and his wife Lulu bought 250 acres of fertile land along the Willamette River and dedicated their lives to farming. After experimenting with a variety of crops, George established the first commercial filbert nut orchard in the United States. Over the next 50 years the Dorris family planted 9,200 trees at the ranch and harvested more than 50 tons of nuts each year.

Now, more than 100 years later, Dorris Ranch continues to make history as a fully-productive commercial filbert orchard. More than half of all the commercial filbert trees now growing in the U.S. originated from Dorris Ranch nursery stock.

Each of the 11 separate orchards was named in order to help hired hands know where to work each day.

The approximate age of each orchard may be determined by looking at the spacing between trees. In the earliest orchards (planted beginning in 1903) the trees are planted very close together. As the years went by, spacing between the trees became greater. Dorris Ranch has a total of 9,250 filbert trees planted in 75 acres.

Most of the trees in the Dorris Ranch orchards are of the Barcelona variety. Because the Barcelona is self-sterile, other varieties—the DuChilly and the Daviana—are planted as pollinators every third tree in every third row.

Today, Willamalane is in the process of removing the Barcelona trees in stages in an effort to fight eastern filbert blight. New blight-resistant trees are replacing the highly susceptible varieties George Dorris planted. 

Filberts are considered a "self-husking" nut. The husk falls off when the filbert drops from the tree. Machines can then pick up the filberts and take them directly to the drying machines. A local orchardist maintains the Dorris Ranch orchards.

Closures and Treatment Information

The historic filbert orchards at Dorris Ranch require seasonal treatment to prevent a variety of infections and invasive species that could harm the trees. To make this happen, our team uses regulated fungicides, herbicides, and insecticides that are recommended specifically for the treatment of these orchards and are part of best practices developed by Oregon State University and the Oregon Department of Agriculture. Here is more information about that program. 

Our process for applying treatment at Dorris Ranch: 

  • We identify our target vegetation that we’re treating, as that determines the options for application and the types of materials we use.
  • We work closely with an orchardist who will make the application, and we always leave a buffer zone around the outer edge of the orchard.
