Broods per Sq. Mi. 10.1 _ 33,2 | | 20.3 63.5 

A total of 289 broods of all classes give a ratio of 63.5 broods per square mile of reservoir habitat. There isa mortality 
of 11.5 percent between the 6. 61 average for all Class 1 broods and the 5. 85 average for all Class 111 broods. 
The high ratio ar ducks, pairs, and broods per acre as determined from this year's study indicates the value of this type 
of habitat in this Unit, and may point the way to management through improvement of reservoirs and smaller impoundments 
for waterfowl.
