3 <br />central Platte River. To accomplish this goal we agreed that we <br />need at least 24 managed nesting islands providing at least 3.6 <br />acres of optimum nesting habitat per island. The preferred <br />height of the islands is at least 3.1 feet above the 0 flow <br />level. <br />?-3. Given the eight alternative management plans laid out in the <br />Biology Workgroup Final Report, describe the quantity of species <br />habitat provided by each plan and its potential for providing for <br />the recovery of the species targeted by the recovery plans -- To <br />answer this question, we simply multiplied the areal extent of <br />the plan configuration by the unit length to arrive at an acreage <br />figure. We assumed that the potential for assisting species <br />recovery would relate directly to the number of acres of habitat <br />provided. Those habitat figures are: <br />Rank Plan # Plan Name <br />Acres Provided <br />1 G Platte River System 684,000 <br />2 F. 89 Mile Plan 113,920 <br />3 A Historic Conditions 103,680 <br />4 D Block/Segment 30,720 <br />5 B Segment 25,600 <br />6 C Block 15,360 <br />7 E Maintain Status Quo .91000 <br />8 . H No Action 0 <br />4. How will the quantity and quality of species habitat be <br />measured to determine success of a plan? -- Habitat quality will <br />k??9 be measured by the components of the species models or those <br />spelled out in the least tern and piping plover habitat <br />management scenario. Quantity equals the number of acres <br />managed. We believe .that it is important to recognize <br />r distribution of managed sites as a component of both quantity and <br />quality of habitat. <br />5. Which plan or plans does the most for meeting the recovery <br />goals for each of the endangered specie? -- Our final analysis <br />revealed that whooping crane roost sites should include 2000 <br />acres of wet meadows and 250 acres of riverine roost; a total of <br />2250 acres per roost site. Tern and plover habitat management <br />should include one managed site of 110 acres in each of ten <br />bridge segments (1100 acres) plus 4 additional managed sites at <br />85 acres each (340 acres). In most instances the Biology <br />Workgroup recommends that tern and plover nesting habitat <br />management units be "tacked on" to the upper and lower ends of <br />managed whooping crane roost.sites. Based on these data,.the
