Page 3. Bullet 1. — Is there a shortage of whooping crane roost habitat at normal flow ranges during <br />migration periods? If so how much is needed and how is it defined? How does distribution of roost habitat <br />over an 80 mile stretch of one river impact a bird that migrates thousand of miles not always on the same <br />route? How do the physical habitat characteristics described influence tern and plover nesting? These <br />birds nest numerous places where none of those variables would be an issue. <br />Page 4. Bullet 2. The several ecologists I am familiar with do not emphasize that the measures outlined <br />should be taken. In fact most agree that the changes outlined will cause a new state of disequalibrium on <br />the river and may result in conditions worse then currently exist. The DOI under other venues has <br />indicated that the Platte River sediment transport has come into equilibrium with current flows, yet they <br />want to disrupt this equilibrium. I think it is appropriate the FWS explain to the Technical Committee how _ <br />they plan to manage sediment and flows and ultimately what they think the river should look like and what <br />processes are going to sustain the habitat so that we as the science branch of this Program can evaluate it. <br />Page 4. Reduction of normal high flows. — What are normal high flows? Many factors affect seedling <br />establishment and removal and this is a greatly simplified and possibly inaccurate description of those <br />processes. <br />Page 4. Wet meadow flows. — The EIS team and others have shown that increased flows in the river have, <br />very little affect on groundwater levels in surrounding areas. Would the FWS please provide to the <br />Technical Committee the study which shows that rising ground water levels thaw soil? Has the FWS <br />evaluated the fact that ground water levels in the central Platte Valley and surrounding areas are at historic <br />highs and how this can occur when supposed river depletions have lowered groundwater? <br />Page 4. Sediment Reductions. — Is sediment transport the principle benefit of spring pulses or is it <br />vegetation scour and wet meadow saturation? Just how does the FWS propose we handle the sediment <br />transport problem? <br />Page 5. First Paragraph. — The reliance of the FWS on past BO's, recovery plans and FWS policies does <br />not offer the stake holders any benefit over individual consultations. The science and logic behind those <br />documents has been brought into question time and again. In my opinion, at least, those question still <br />remain today, therefore their use, as a means of evaluating this Program is not justifiable until they have <br />been peer- reviewed and even then they are only a starting point for adaptive management. <br />Page 5. I.A. 1. — How will changes in quantity and quality of roosting habitat provide benefit to whooping <br />cranes? How will this be evaluated? The Technical Committee has indicated several times that the <br />whooping crane model may be used to design management but not evaluate success. <br />Page 5. I.A. 2. — How will changes in quantity, quality and spatial distribution of roosting habitat provide <br />benefit to whooping cranes? Is a whooping crane that stops at Overton better off than if he had to fly down <br />to the Rowe Sanctuary? It is highly unlikely based on historical accounts the entire river was one wide <br />unobstructed channel. <br />Page 5. I. A. 3. — What is sustainability? Do we know enough to manage sediment? Is the FWS willing to _ <br />take responsibility if this sediment management results in a new disequilibrium that has negative effects on <br />species and habitat? <br />Page 6. I. B. 1. — The first question is are there flow periods important to wet meadow hydrology and what <br />are they? (Question I. B. 3. A.). <br />2 <br />Page 6. I. B. 3. — What is biological quality and sustainability of wet meadow feeding habitats? <br />Page 6. I. C. 1 & 2. — While these may be important questions can the Program effect them? <br />
