Summary 
A 45 percent loss in the breeding duck index for the Nebraska sandhills 
occurred during 1955 as compared to 1954. This loss appears to have been 
directly related to the loss in available habitat which was very severe in the 
eastern area and minor in the central and western areas. 
Production appears to have been good; possibly some of the loss in 
breeding ducks was offset by good hatching success.
