News release BLM. The Bureau of Land Management (BLM) will spray noxious weeds at the Hinsdale Garden and portions of the Dean Creek Elk Viewing Area, east of Reedsport on Highway 38, on Monday July 25. Visitors to these areas should avoid application locations, which will be evident by blue colorant on plants. The BLM will spot apply the herbicide Glyphosate to eradicate purple loosestrife, an Oregon State Department of Agriculture listed “Noxious Weed.” The tall, purple flower adorned plant grows along streams and wetlands, and crowds out other plants that wildlife need for food and shelter. Other listed “Noxious Weeds” that will be treated are Scotch broom and Himalayan blackberry. For additional information, please contact the Coos Bay District Office at 541-756-0100.
