Integrated Vegetation Management Provide public information on washing vehicles to avoid transporting undesirable plant seeds onto public lands; sign boards; handouts at recreation sites Provide public information on washing vehicles to avoid transporting undesirable plant seeds onto public lands; sign boards; handouts at recreation sites Coordinate with 8 county weed boards and provide funding to 5 counties for weed control on BLM lands Coordinate with 8 county weed boards and provide funding to 5 counties for weed control on BLM lands Using biological control agents in coordination with Oregon Dept of Agriculture Using biological control agents in coordination with Oregon Dept of Agriculture

7. Integrated Vegetation Management Use a variety of approved chemicals for targeted species Use a variety of approved chemicals for targeted species Treatment priorities include high use recreation areas; acquired lands (abandoned agricultural fields); areas with high concentrations of noxious weeds; riparian areas; areas of whitetop Treatment priorities include high use recreation areas; acquired lands (abandoned agricultural fields); areas with high concentrations of noxious weeds; riparian areas; areas of whitetop Before treatments occur we contact adjacent landowners and neighbors. Many treatments are a result of landowners calling us Before treatments occur we contact adjacent landowners and neighbors. Many treatments are a result of landowners calling us

12. How Vegetation Treatment EIS Would Help Target-specific herbicides are more effective at treating the problem Target-specific herbicides are more effective at treating the problem Safer to use in sensitive riparian habitats Safer to use in sensitive riparian habitats Reduced residual off-site effects Reduced residual off-site effects More cost effective More cost effective
