Project/Client:  Bald Hill Park Oak Restoration, City of Corvallis, Oregon, Parks and Recreation
Corvallis, OR
Scope:  IRM worked in partnership with the Nature Conservancy to restore the oak woodlands at Bald Hill Park.  Treatments included:

  • Thinned 8 acres of oak to open woodland tree density
  • Created 4 acres of wildlife wood piles
  • Seeded 6 acres with native grass and annual forbs
  • Restored 4 acres of savanna density habitat to conditions favorable for associated bird species
  • Tilled and seeded 6 burn piles to ameliorate soil degradation from burning brush and cut trees past treatments

The restoration objective was to recreate savanna conditions and support home range habitats of open oak dependent species including acorn woodpecker, white-breasted woodpecker, and neo-tropical species including lazuli bunting, black-headed grosbeak, and Bullock’s oriole.  IRM used two implements on its LightfootTM machine including the Fecon Bullhog® to remove non-native species and competing understory brush; and the Tree Shear to thin and remove small diameter trees.  Removing the non-natives, competing brush and small trees, will provide better habitat and growing conditions for native oak populations. Herbicides were used to eradicate non-native species grasses and forbs.

Project/Client:  Klickitat Landscape Level Fuels Reduction and Oak Restoration Project, Columbia Land Trust
Location:   Klickitat River, Washington
Scope:   IRM restored an oak savanna and woodlands in the Klickitat River Canyon, an area that contains the largest concentration of these habitats in Washington State.  Activities included thinning stands to remove conifers and overstocked oak, use of goats and brush mowing to reduce shrub cover, and native seeding to re-establish bunchgrass communities.

Silvicultural prescriptions were based on reducing extreme fire behavior and associated fire effects, increasing mast production and tree vigor, and habitat needs of the western grey squirrel.  A combination of low-impact skid steer (LightfootTM) with a sheer, and hand crews were used during thinning operations.

Project/Client: Wildland Urban Interface (WUI) Fuels Reduction Project
Location:  Sutherlin, Oregon
Scope:  IRM was hired to create a 25 acre fuel break within the Wildland Urban Interface (WUI).  The Lightfoot was mounted with the Fecon Bullhog® to mow and masticate a field of English hawthorne which has invaded an old pasture. The hawthorne measured up to 6″ in DBH and over 15′ tall.  Follow-up treatment included planting to re-establish vegetation  on this site.
