Cone depredations by the red squirrel in black spruce stands in Newfoundland: implications for commercial cone collection
The proportions of black spruce (Piceamariana (Mill.) B.S.P.) cones per tree that were removed by red squirrels, Tamiasciurushudsonicus (Erxleben), in years with small cone crops (1985–1987) ranged from 15 to 64% by the end of August and from 64 to 96% by the beginning of October, whereas in a year...
