About 489,000 deer are estimated to be in California as of 2012, slightly above the estimate provided by California Fish and Game in 2011, although this estimate does not track with the declining harvest data.  [research]  The harvest data for 2011 shows a steep decline, but this is explained as an result of tag changes and non-reporting.  In 2011 the harvest of bucks by age class were:  Two point bucks:  51.2%;  Three point bucks:  29.9%; Four point bucks:  15.4%;  Four point plus bucks:  2.7% (source CA Hunting Digest - 2012, page 21).  The very high proportion of immature bucks taken as harvest and the very low buck to doe ratio contrasts with the efforts of deer management that many states have enacted since 2000 where stronger buck age restrictions and some balance of the buck to doe ratio have been implemented.
