B. Bottom land feeding and loafing habitat: Constituent Element of Critical Habitat <br />Primary emphasis on wet meadows/ lowland grasslands: <br />1) Do Program changes in river flow management affect the river discharge during <br />periods that are considered important to wet meadow hydrology? <br />2) How do Program changes in flow management affect river flow /stage relationships, <br />or the sustainability thereof? <br />a) What changes or trends in the channel morphology (e.g., continuous active <br />channel width, wetted width, channel incision) occur following Program <br />implementation? <br />b) How do changes in channel morphology affect river stage? <br />3) Do Program changes in river flow and land management affect the biological quality <br />and the sustainability of wet meadow feeding habitats. <br />a) How does river stage relate to depth to groundwater on adjacent meadows? <br />b) Which land management/ restoration techniques result in high quality wet <br />meadows? <br />C. Isolation: Constituent Element of Designated Critical Habitat <br />1) Do changes in land -use patterns affect the availability and suitability of roost habitat? <br />2) Do changes in land -use patterns affect the availability and suitability bottom land <br />feeding and loafing habitats? <br />D. Program Effects on Whooping Cranes (Species Response) <br />1) Do Program changes in land and river flow management affect the relative frequency <br />of whooping crane stopovers? <br />2) Do Program changes in land and river flow management affect the relative <br />distribution of whooping crane stopovers along the Platte River? <br />I <br />n <br />substrate? <br />(2) <br />Can EA releases contribute effectively to maintenance of <br />unobstructive bare substrate? <br />(3) <br />Do measurements of discharge, sediment, vegetation and channel <br />morphology support the sediment/vegetation model? <br />C) What are the effects of land management practices on sustainability of roost <br />habitat? <br />(1) <br />What are the short- and long -term effects of channel widening on <br />channel morphology (on site and downstream)? <br />(2) <br />What are the short- and long -term effects of island leveling on <br />channel morphology (on site and downstream)? <br />(3) <br />How does tree/brush removal affect short and long -term quantity and <br />distribution of whooping crane roosting habitat? <br />B.
