DEER ABUNDANCE AND SCARCITY THE STATEWIDE PICTURE Based on hunting information, major peaks and troughs in the buck kill occur approximately in 10-year intervals (Figure 1). Although deer tag sales showed a fourfold increase during the 1927- 1960 period, there were sales declines during the middepression (1932- 33), during World War II (1942 in particular), and in 1957-1958. These hunting-effort decreases could explain the low deer kill, were it not for the lack of correspondence in the hunting-success ratio. Thus, the 1940 peak in deer kill was followed by an increased number of hunters in 1941. In 1941, however, the hunting-success ratio and deer kill fell off, suggesting that deer had either decreased or were harder to kill. During 1942 and 1943, the much-reduced number of hunters did not find deer easier to kill. Instead, the hunting-success ratio continued to fall to a low in 1943, paralleling the low in deer kill. Reduced deer abundance is again suggested. Following the 1954 peak in deer kill and hunting success, a similar pattern is shown. The numbers of hunters increased for two more years, while the deer kill and the suc- cess ratio declined. NUMBER OF DEER TAGS SOLO. FIGURE 1. Relation of statewide buck kill with deer tag sales and hunting success ratios. Solid vertical lines show years of high kill; broken vertical lines indicate years of low kill. However, if the statewide buck kill is examined critically, county by county, it does not show any marked synchrony throughout the various regions of California. Deer do not increase and decrease in all areas simultaneously. In the years of major statewide peaks, 1931, 1940, 1954, a high percentage of the counties did produce peak kills and most of the other counties peaked either one year before or one year after. There is thus an indication that thr
