Heavy Grazing of Canadian Bluejoint to Enhance Hardwood and White Spruce Regeneration
Abstract:Wet, disclimax stands of Canadian bluejoint (Calamagrostis canadensis [Michx.] Beauv.) created by logging were heavily grazed by cattle and horses years 5 through 8 after logging to weaken the grass and favor regeneration of hardwoods and white spruce (Picea glauca [Moench.] Voss). Seedling densities of hardwoods and white spruce in heavily grazed stands were not significantly different (P < 0.05) from those in ungrazed stands. Heavy grazing reduced herbaceous cover and litter but was not detrimental to runoff water quality. Heavy grazing was not effective for increasing regeneration in wet disclimax stands of Canadian bluejoint where the grass had already increased following overstory removal, but earlier application and use in drier sites should be considered. North. J. Appl. For. 18(1):19–21.
