Whychus Canyon Preserve Forest Restoration

Details on the forest restoration at Whychus Canyon Preserve.

The Land Trust acquired Whychus Canyon Preserve in 2010. One of our goals for the Preserve is to improve wildlife habitat and the first way to do that is by restoring the native forests of the Preserve.

The Land Trust hired restoration ecologist Darin Stringer of Pacific Stewardship to create a forestry plan for the Preserve. During the spring and summer of 2012, major forest restoration work began with the initial focus on thinning juniper from ponderosa pine and aspen stands.

Forests at Whychus Canyon Preserve

Whychus Canyon Preserve hosts a diverse mix of forest types with juniper woodlands on the plateau above the canyon, ponderosa pine groves along the shadier north faces of the canyon walls and floor, and aspen stands along the wet creek bottom.

Ponderosa Pine Woodlands

Ponderosa pine woodlands at the Preserve provide important shelter and food for species moving along the habitat edge.

The problem: over time fire suppression and juniper encroachment made those pine stands more vulnerable to beetle outbreaks and mistletoe infestations.
The solution: The Land Trust thinned juniper and a few pines, to reduce catastrophic fire and insect danger while improving wildlife habitat for a myriad of bat and bird species as well as elk and mule deer.

Aspen Woodlands

Aspen woodlands can be found at Whychus Canyon Preserve in groves along the canyon floor where Whychus Creek provides moisture. They also provide shelter and food for wildlife and are limited in our region due, in part, to fire suppression, juniper encroachment, and grazing.

The problem: aspen stands were facing stiff competition from juniper and excessive browse by mule deer.
The solution: The Land Trust thinned the juniper and created downed juniper corrals around some aspen groves to keep deer from browsing the small vulnerable sprouts. The end result will be healthier aspen woodlands that benefit water quality and quantity and provide habitat for nesting and migratory songbirds.

Future Plans

During the fall of 2012, the Land Trust plans to burn slash piles from the thinned steep slopes of the Preserve. Once we secure additional funding, we’ll begin the next phase of forest restoration at Whychus Canyon Preserve: thinning juniper along the north canyon rim and southern plateau.

Funding for this project was made possible by the Oregon Department of Fish and Wildlife matched by contributions from Land Trust supporters during the Preserve's acquisition campaign. Thank you!
