<br />South Platte River, Chatfield Downstream Channel Improvement Project- Vegetation Management Plan <br /> <br />In addition to vegetation removal, it is recommended that previous treatment sites are monitored <br />to evaluate treatment techniques and impacts on water quality and erosion both in-channel and <br />near structures in order to best continue planning for and adaptive management, assessment of <br />vegetative debris removal and vegetative seeding with Corps approved species on treatment sites <br />and sensitive habitats. Species and amount of vegetative re-growth in treatment sites should be <br />assessed. <br /> <br />It is also recommended that continued mitigation and vegetative enhancements are implemented <br />to offset negative impacts of riparian habitat removal in off-channel and upland locations. The <br />effectiveness of vegetation removal as well as the mitigation projects should be assessed to attain <br />both acceptable Corps compliance ratings for floodplain channels and adequate habitat quality, <br />wildlife and vegetation species diversity, stream-bank erosion control, and water quality <br />protection. <br /> <br />Short-term and long-term projects for vegetation management in the South Platte River Chatfield <br />Downstream Channel should be identified for the future and adaptive management should be <br />continued in perpetuity. <br />I - i <br /> <br /> <br />\'Il <br /> <br />I ' <br /> <br />Monitoring and Adaptive Management <br />It is recommended that regular monitoring and assessments take place at the treatment sites to <br />evaluate: Effectiveness of treatment techniques, erosion and water quality impacts, sandbar <br />conditions, wildlife use, river access, and recreational impacts. Adaptive management <br />approaches allow for adjustments to treatment techniques based on evaluations and assessments. <br /> <br />Page 17 <br />Final Report - April 30, 2008 <br />
