Planting Oaks
We
have been conducting research to determine the best techniques for establishing
Oregon white oaks. We have trials at Fort Lewis and elsewhere in western
WA where we are testing fertilization at time of planting, weed suppression
alternatives, irrigation, and tree shelters. In our trials, seedlings
grown in solid tree shelters had greater growth than seedlings in mesh
shelters or no shelter (see photos and graph below).

A solid tree shelter (left) and a mesh tree shelter (right) both prevent browse damage, but the solid shelter also acts as a mini-greenhouse. The plastic mats block weeds but are perforated to allow rain water to pass through. A net over the top of the solid shelter keeps birds from getting inside.

During their first two years after planting, oak seedings in solid tree shelters grew more than those in mesh shelters.

How you can help:
We have started a volunteer-based Oak Planting Survey. If you are planting oak seedlings, record seedling measurements and planting information on our form and add your data to our observations (we will remind you to remeasure the seedlings in the future). When we have enough information, we will summarize the results and make them available to everyone. You can request free tags to label your seedlings and can arrange to borrow equipement to measure seedling height or diameter by email: wdevine@fs.fed.us (or see team directory for mailing address and phone numbers).
