Success of the Season 
ee a Re oe aa 
No suitable method of obtaining satisfactory quantitative information as to 
State-wide duck production is known. However, for some years annual brood 
counts have been taken over selected routes in some of the State's better duck 
habitat. These counts yield certain information of questionable value as to duck 
production in the specific areas sampled. The sample involved is extremely small, 
consisting of about one-quarter of one percent of the total duck producing area. The 
data from these counts, shown in the following table, indicates reproductive success 
in 1952:-to be less than that of 1951 and that considerably fewer ducks will be produced 
in North Dakota in 1952 than in 1951.
