Define monitoring criteria (from II Al and A2). snch as life stages <br />and habitats. sampling intensity, sampling procedures, and data to be <br />collected. Use information from the research study and other appropriate <br />studies to determine significance of change in population size, stability, <br />and general well being of the species and its habitat. Evaluate and revise <br />the monitoring program as necessary. <br /> <br />2. As significant information becomes available, and at least at five <br />year intervals coordinated with the review of the Colorado River Storage <br />Project, evaluate monitoring results to determine the necessity of <br />changing project operation so that it contributes to the likelihood fQr <br />recovery of the humpback chub in the project area. Use monitoring <br />information to determine the success of operational changes or other <br />measures to imprpve the status of the humpback chub in the Grand Canyon. <br />Reinitiate formal Section 7 consultation if monitoring information reveals <br />that project operation is likely to jeopardize the continued existence of <br />the humpback chub or if.new information reveals effects of. the action that <br />may affect listed species in a manner not previously con~idered. <br /> <br />!. <br />,.\ <br />i' <br />r;: <br />~j <br /> <br />'"" <br />:~ <br />~~ i <br />~ <br />~, <br />" <br />o <br /> <br />, , <br />,;.- <br /> <br />3.

The monitoring program needs to be long-term, if necessary the life <br />of the project, since there is a wide variance in precipitation. the <br />resultant reservoir releases, and changes in downstream environments from <br />those releases. Also, with the longevity of the species (40+ ycars) , <br />short-term monitoring efforts may not accurately identify significant <br />trends. Where possible, cause and effect hypotheses will be tested and <br />compared to environmental or other changes that may affect the humpback <br />chub. Monitoring of other resources affected by Glen Canyon. such as <br />sediment and ~'ater quality, should be integrated wi th this effort. <br /> <br /> <br />B.

During the last <br />year pf the humpback chub studies, a long term monitoring program will be <br />developed, reviewed. and implemented by the Consulting Team's agencies. <br /> <br />5 <br />
