Overview <br />This report summarizes the 2005 Climax Molybdenum Mine (Climax) noxious and targeted <br />weed management efforts. Weed control management on the Climax property was initiated in <br />1999. During the growing season of 1999, Habitat Management, Inc. (Habitat Management) <br />conducted a weed survey of the project area to characterize the extent of weed infestation. The <br />survey identified the following twelve species of noxious or targeted weeds growing on the <br />property: <br />• Mayweed chamomile (Anthemis cotula) <br />• Oxeye daisy (Chrysanthemum leucanthemum L.) <br />• Canada thistle (Cirsium arvense L.) <br />• Yellow toadflax (Linaria vulgaris L.) <br />• Musk thistle (Carduus nutans L.) <br />• Hoary Cress (Cardaria draba) <br />• Diffuse Knapweed (Centaurea d~sa) <br />• Spotted Knapweed (Centaurea maculosa) <br />• Russian Knapweed (Centaurea repens) <br />• Field Bindweed (Convolvulus arvensis) <br />• Houndstongue (Cynoglossum officinale) <br />• Leafy Spurge (Euphorbia esula) <br />The information obtained during the weed survey was used to develop an integrated pest <br />management plan for Climax. Weed management under this plan was implemented on a project- <br />wide basis in the summer of 2000 and has continued over the past five growing seasons. <br />1999 Weed Survev <br />Habitat Management initiated a pedestrian weed survey that ranked weed populations by their <br />densities, potential to spread, and difficulty to control. The survey identified 188 distinct sites <br />found on lands controlled by Climax. The weed survey was conducted to identify the nature and <br />extent of infestations within the project azea and to further define the weedy areas. Survey data <br />
