Abstract
The Mt. Hood National Forest (Forest) and Columbia River Gorge National Scenic Area in
Oregon (Scenic Area) are proposing invasive plant treatments on 208 sites (approximately
13,000 acres). The purpose of this project is to eradicate, contain and control invasive plant
infestations, to reverse the negative impacts caused by invasive plants, and to restore healthy,
native plant communities and functions at the impacted sites in a cost-effective manner that
meets current management direction. The Proposed Action would utilize
integrated weed management treatments. The treatments include: 30 acres of herbicide only
treatment; 50 acres of manual and mechanical treatments; 310 acres of herbicide plus mechanical
treatments; 327 acres of herbicide plus manual treatments; 1510 acres of herbicide plus manual,
mechanical, and cultural; 10,736 acres of herbicide plus manual and mechanical treatments.
Additional acres would be added through an early detection / rapid response strategy (EDRR).
Description
906 pp. Abstract, maps, tables, figures, references, glossary, index, appendices. The proposed treatment areas cover
approximately 13,000 acres in Multnomah, Hood River, Wasco, Clackamas, Jefferson, and
Marion counties (See Figure 2-1). This represents 1.1 percent of the National Forest System
lands within the Forest and Scenic Area. Approximately 11,000 acres are located within the
Forest and 2,000 acres within the Scenic Area. The Forest acres are distributed on all four ranger
districts, including 2,444 acres on Barlow Ranger District, 5,596 acres on Hood River Ranger
District; 1,270 acres on Clackamas River Ranger District; and 1,868 acres on the Zigzag Ranger
