Waterfowl harvest at Tule Lake National Wildlife Refuge (NWR) for the 6-yr period 1936-41 is described and compared with a recent (1978-83) period. During the early period 46,987 geese and 76,143 ducks were bagged during 48,610 hunter-visits. Hunting seasons were 30 to 60 d in length. Greater White-fronted Geese Anser albifrons, followed by Northern Pintails Anas acuta, and Cackling Canada Geese Branta canadensis minima were the most important birds in the harvest. Average harvest was 1.0 goose and 1.6 ducks per hunter-visit. A short (30-d) and late hunting season drastically curtailed harvest in 1937. Reduced hunting activity in 1941 was attributed to military mobilization. During the 1978-83 period 34,416 geese and 63,458 ducks were bagged during 69,170 hunter-visits. Hunting seasons during this period were mostly 93 d in length. The most important bird in the harvest was the Mallard A. platyrhynchos, followed by White-fronted Goose and Northern Pintail. Average harvest was 0.5 goose and 0.9 duck per hunter-visit. In general dabbling ducks increased in overall importance while diving ducks decreased between the two periods. Harvest decreased 20.5% while hunter-visits increased 42.3%.
