Refuge, Idaho. The goal of this effort is to estab- 

 lish an additional isolated population so that a 

 single calamity could not destroy the entire popu- 

 lation (Kuyt 1976a). Eggs were also transplanted 

 in 1976 and 1977. As of 1977, six birds have 

 been successfully raised and now migrate with the 

 sandhill cranes (WCRT 1977). 



Other management suggestions (Allen 1952) 

 which have not been achieved include inclusion of 

 Mustang Lake into the Aransas refuge, closure of 

 it to fishing, and conversion of the lake to the 

 predredged condition. Allen (1952) also suggested 

 extending the boundaries of the refuge, and this 

 has been accomplished in part by the National 

 Audubon Society's leasing of lands adjacent to 

 the refuge (WCRT 1977). 



Critical Habitat was designated in 1978 (43 

 FR 20938; 15 May 1978) and includes these areas: 

 Colorado Monte Vista National Wildlife Refuge 



(all), and Alamosa National Wildlife 



Refuge (all). 

 Idaho Grays Lake National WildUfe Refuge

 (all). 



Texas Aransas National Wildlife Refuge (all), 



northeast to Pringle Lake, southeast 

 to Gulf Intracoastal Waterway plat- 

 form channel marker 25, and north-

Eight additional areas have been proposed as 

 critical habitat (43 FR 36588; 17 August 1978): 

 Kansas Kirwin National Wildlife Refuge. 

 Montana Medicine Lake National Wildlife 



Refuge. 

 Nebraska A section of the Nebraska River in 

 Brown, Burleigh, Divide, Dunn, Em-
