Conclusions 
The State and Regional totals shown in the table showing 
status or production reflect better production this year than in 1956, 
Production increases are noted in the data presented in the table showing 
summer brood survey for the three important nesting species--blacks, 
woodies and mallards. 
Because of the marked contrast in the phenology between 
1957 and 1956 a conservation but optimistic interpretation of the data is 
necessary as follows: 
Black Duck = Slight, moderate increase 
Wood Duck - Slight increase 
Mallard - Moderate increase
