Before 1944, Klamath Basin National Wildlife Refuges (NWRs) in northeast California (Figure 2) were the only public lands in the state open to waterfowl hunting. In response to a heavy demand for waterfowl hunting opportunities and to preserve wetland habitats, an extensive public hunting area (PHA) network was subsequently established in California (Kozlik 1955). Currently, 20 state areas and 15 NWRs are open to waterfowl hunting in California. Prime waterfowl hunting opportunities have enabled California hunters to harvest more ducks than do hunters in any other state, averaging million ducks per year during 1971-80 (Carney et al. 1983). California duck hunting regulations (Figure 3, Bartonek et al. 1980) have been relatively stable and liberal compared to those in other flyways. Hunting seasons have ranged from a 44-day split season to a 95-day continuous season (average 83 days) and daily bag limits have varied from 5 to 7 ducks with restrictions some years on canvasbacks, Aythya valisineria, redheads, A. americana, wood ducks, Aix sponsa, and hooded mergansers, Lophodytes cucullatus. During 1952-58 and 1974, 2 to 4 additional northern pintails or American wigeon, Anas americana, were allowed. During 1985-87, only 1 female mallard, A. platyrhynchos, and 1 female northern pintail were permitted in
