Camp Bonneville

Forest and invasive vegetation management

Clark County Environmental Services is working with Public Works to effectively manage the Camp Bonneville forests that support a diversity of plants and animals.

Forest thinning

The Camp Bonneville Forest Stewardship Plan (PDF) calls for selective thinning and other techniques to create a healthy forest ecosystem. The modest income generated from these wood products will be used at Camp Bonneville for forest operations, property management and other activities, such as road maintenance.

Clark County’s Camp Bonneville forestry program is certified by the Forest Stewardship Council and the American Tree Farm System.

Invasive vegetation control

The county is working to effectively control the following invasive and non-native species at Camp Bonneville:

  • Bull thistle
  • Canada thistle
  • Herb Robert
  • Meadow knapweed
  • Mouse-ear hawkweed
  • Non-native blackberry
  • Queen Anne’s lace
  • Scot’s broom
  • Tansy ragwort

Control methods

Control methods, such as the use of herbicides and power tools or pulling by hand, are used annually from May through October. All control efforts are carefully implemented to ensure that state-listed plant species, like the hairy-stemmed checker mallow, are not harmed. Herbicides are applied according to strict safety guidelines set by the manufacturer.

Focus areas

Control efforts are focused on Camp Bonneville’s valley floor where Lacamas Creek flows through the property, gravel roads, trails and near buildings. Additional areas will be treated as necessary to maintain a healthy forest ecosystem. Some areas are not open for invasive species control due to ongoing cleanup of munitions of explosive concern and other hazardous materials.
