e. Remarks: This area affords nesting habitat only occasionally. During 
the previous four years this region was so dry that no survey was made, and so we 
have no comparative data. Also we have no data on the average nesting success or 
brood size on which to base production. The above total is not included in the 
State-wide totals and is included in the report only for future comparison. 
8. State-wide Trend. 
A comparative summary of nesting pairs of waterfowl for the past four 
seasons together with final fall population including young plus resident adults is 
shown in the following table. These figures for each year have been derived from 
the preceding tables. In almost all cases the figures shown previously for "nesting 
pairs" are more accurate than those indicating "total fall population.'' The 1952 
figures are not directly comparable since basic changes were made on Tule Lake 
and Lower Klamath refuges in 1952,

State-wide Trend excluding Tule Lake and Lower Klamath. 
In view of the basic changes made on the Tule Lake-Lower Klamath areas, 
the only set of comparable figures on nesting pairs and production is presented in the 
following table. The figures shown in this table have been extracted and combined 
from the previous sections of this report. 
Remarks: Comparable figures from previous years indicate that there was a 
continued increase in the Canada goose population. A significant increase is noted 
in mallards, pintail and cinnamon teal, whereas the production of redheads and 
ruddy ducks shows a decrease. The other duck species remain essentially the same. 
An over-all increase of approximately 30 percent is indicated for ducks and a 
50 percent increase in coots.
