摘要: In May, 1935, a "strip method" for censusing snowshoe hare populations was devised and it used nearly two years on number of areas in St. Louis County, Minnesota. Although the results were encouraging, method has not been thoroughly tested. It is presented at this time as tentative proposal hope that will be tried by others various varts range. The modification R. T. King (unpublished data) to census ruffed grouse populations. Because King's described Fisher (1939) others, seems unnecessary present detailed description here. Briefly, taken walking along lines . mile apart determining "flushing distance" birds seen, distance from point where flushed observer flushes. Success with due largely fact when these flush they make considerable noise their wings, so none are overlooked. line population strip, length which miles covered, width twice average flushing distance. directly applicable hares because difference flush-
