“…Besides, our results on the effect of controlled fire on pine regeneration are perfectly in line with studies performed in northern areas (e.g. Tellier et al, 1995;Hille and den Ouden, 2004;Hancock et al, 2009), these studies also emphasising the correlation between fire intensity and regeneration success. Chopping in our study is, with low-intensity controlled fire, an inappropriate treatment for forest regeneration.…”

“…Low fire intensities stimulated Corylus cornuta sprouting and height growth of Rubus ideaus (Johnston and Woodard 1985). Biomass nutrient retention (Duchesne and Tellier 1997) and soil seed bank and competing vegetation dynamics along with P. resinosa and P. strobus seedling performance are also affected by prescribed burning intensity (Tellier et al 1995(Tellier et al , 1996Whittle et al 1997). Soil microbial activity and diversity were also affected by fire intensity (Duchesne and Wetzel 2000;Staddon et al 1998aStaddon et al , 1998b.…”

The effects of prescribed fire intensity and depth of burn were investigated on Lowbush Blueberry (Vaccinium angustifolium) and Velvet Leaf Blueberry (Vaccinium myrtilloides) stem density, blueberry production and the number of blueberries/stem in a clear-cut Jack Pine, Pinus banksiana, ecosystem of eastern Ontario. Blueberry production and stem density were significantly (P < 0.001) increased by low intensity prescribed fires of 597 and 1268 kW/m. In contrast, prescribed fires of medium and high intensities did not affect blueberry production and stem density. The number of blueberries/stem was not affected (P = 0.056) by prescribed burning, two years after treatment. Pearson's multiple correlation analysis showed that blueberry production (R: -0.683, P < 0.01), stem density (R: 0.733, P < 0.01) and the number of blueberries/stem (R: 0.803, P < 0.01) correlated with depth of burn. As well, blueberry production (R: 0.507, P < 0.05) and stem density (R: -0.504, P < 0.05) correlated with fire intensity. Depth of burn was a better predictor of berry production and stem density than fire intensity. These results suggest that only low intensity fires with little penetrating effect in the ground should be used to manage blueberry crops.

“…Competition by non-crop vegetation on outplanted Pinus strobus L. and Pinus resinosa Ait. was decreased by prescribed burning and scarification (Tellier et al 1995b). However, the ecological role of non-crop vegetation in our research plots is unknown.…”
