These measurements are different from an <br />inventory. Inventories are a measurement, or a number of measurements, made at a specific <br />point in time. Inventories are often used to establish baseline conditions against which all <br />other measurements are compared, and they are generally the first step in conducting a <br />monitoring effort. The distinguishing attribute of a monitoring effort is the measurement of <br />change over time. <br />Long-term monitoring in the Colorado River ecosystem is conduFted to, detect and <br />-to J...~r""""'" If <br />project both expected and unexpected changes in this ecosystem, ils"refilteCHg the ROD- <br />~\.."re:li&I"l fi'o};- <br />designated preferred alternative or other request from the Secretary or the AMWG.

The <br />success of monitoring requires stability and consistent methodologies that are modified only <br />after in-depth evaluations. Protocols will be developed and reviewed at different intervals for <br />scientific relevance. Maintenance of long-term databases and archives is an essential <br />element of the monitoring program. <br />Monitoring programs will be initiated through a competitive selection processes that <br />includes an open request for proposals, which may be awarded for up to five years, as <br />awropriate. Monitoring programs will be selected through an independent peer review <br />process, evaluation by GCMRC staff and consultation with the AMWGrrWG. Criteria for <br />selection of differing proposals will include support of management objectives and <br />information needs, scientific capability and merit, and cost effectiveness. Projects and <br />programs will be administered as contracts, cooperative agreements or interagency <br />agreements. <br />All monitoring data sets will be accessible to outside investigators and interested <br />parties through developed information and technology services, except for selected sensitive <br />data restricted by law, such as endangered species and cultural resource locations or <br /> <br />November S, 1998 <br />SecoDd Draft - Do Not Cite, Photocopy, or Distribute <br /> <br />26 <br /> <br />I <br />~"0 <br />-Yrf' lJ · <br />II~ <br />. <br />
