<br />6 <br /> <br />137 4) Modeling of fme and coarse sediment flux - real-time and decade-averaged <br />13 8 estimation of sediment inputs from all tributaries, in combination with estimated <br />139 grain-size evolution and downstream transport within the mainstem, as a means <br />140 of tracking the total sediment budget of the ecosystem. <br />141 <br />142 The Biological Resources Program <br />143 Monitoring and research activities for biological resources are intended to develop <br />144 information about the structure and function of the Colorado River ecosystem, as well as the <br />145 impacts of differing dam operations on the ecosystem and associated flora and fauna. It is <br />146 key that relationships between the biotic and abiotic components of the Colorado River <br />147 ecosystem be addressed to predict impacts on critical biological resources. Monitoring <br />148 activities will address management objectives and information needs within two <br />149 programmatic activities: an aquatic and a terrestrial monitoring program. Specific research <br />150 projects will be implemented to address specific questions related to the aquatic food base, <br />151 native and non-native fish species, riparian vegetation, avifauna, and endangered species <br />152 such as the Kanab ambersnail and the southwestern willow flycatcher. The effort will <br />153 provide the knowledge base required to implement ecosystem management strategies within <br />154 an adaptive management framework. <br />155 It is generally recognized that water quality changes from Lake Powell through Grand <br />156 Canyon primarily affect biological components of the aquatic ecosystem. It is proposed that <br />157 water quality program components be integrated under the direction of the Biological <br />158 Resources program as part of this five-year strategic plan. As appropriate the biological <br />159 resources monitoring and research program will consider and address information needs <br />160 related to the Biological Opinions presently guiding endangered species management. <br />161 <br />162 The Socio-cultural Resources Program <br />163 The Strategic Plan incorporates a more comprehensive perspective of cultural <br />164 resources than those outlined in the Programmatic Agreement (PA). This perspective is <br />165 derived from objectives and information needs specified by agencies, Native American tribes <br /> <br />November 5, 1998 <br />Second Draft - Do Not Cite, Photocopy, or DistrIbute <br />
