<br />communities associated with different now regimes effect fish <br />reproduction and survival? <br />Question: How is the encroachment of native and non-native vegetatiou ou to <br />recreation sites related to now regimes? <br /> <br />. <br /> <br />Need/Rationale: The Management Goal states: "protect or improve riparian and <br />spring communities within CRE, including T &E species and their critical habitat." <br />Several research and monitoring emphasis are important for the next five years, <br />including: <br /> <br />. Investigations as to how the occurrence and state of marsh and backwater <br />communities fonned under differing flow regimes effect fish reproduction and <br />survival. The question requires an integration of aquatic resources research <br />and terrestrial habitat. It could include addressing the importance of terrestrial <br />(allochthonous) inputs to food base in some backwaters. <br /> <br />. Monitor the status of seeps, springs, and related communities, including <br />Kanab ambersnail habitat and their association with differing flow regimes. <br /> <br />. Evaluate remote sensing technology to track the encroachment of non-native <br />and native vegetation onto recreation sites under alternative flow regimes. <br />This is a combination of research and monitoring to detennine how to <br />interpret remotely-sensed infonnation. <br /> <br />. <br /> <br />Approach: There are important elements of the terrestrial vegetation program <br />that need to be continued and integrated with other critical needs. Some ground <br />measurements will need to be continued at a much lower frequency. Core monitoring <br />and research as currently specified are sufficient to aid in the understanding of how, <br />under differing flow regimes, the terrestrial ecosystem may affect aquatic resources of the <br />CRE, the state and condition of the KAS and its habitat, and the affect of vegetation <br />encroachment on campsites, and the subsequent influence on recreational experience. <br /> <br />GCMRC SCIENCE MANAGEMENT STRATEGIES <br />TO SUPPORT RESEARCH, DEVELOPMENT, <br />AND MONITORING PROGRAMS <br /> <br />The comprehensive mission and role ofGCMRC within the GCD AMP as <br />outlined in the above science strategy, set against the summary of its capabilities, <br />surfaces several issues, opportunities and concerns that require new science management <br />strategies for the Center. GCMRC assumes a dynamic GCD AMP setting, in which <br />continued interaction of managers and scientists is necessary, including modification in <br />program strategies as needs arise. The following issues, opportunities and conccrns, if <br />successfully addressed with proposed science and science management strategies over the <br /> <br />USGS SBSC GCMRC Strategic Science Plan - FY 2005-2009 <br />Draft, October 22, 2004 <br /> <br />. <br /> <br />22 <br />
