Two sites 90 km apart were used: Armagh and Duchesnay. Each site had four replicates of the treatments in a randomized block design. The effect on light availability was similar in the two sites: the 0%, 40%, 50%, 60%, and 100% cuts transmitting a mean of 5%, 21%, 26%, 30%, and 94% of full light, respectively, during the first summer. Soil temperature increased only in the 100% cut (4-5 \u00b0C, maximum daily temperature). Soil disturbance during harvest was higher at Duchesnay than at Armagh, which clearly improved seedbed receptivity, particularly to yellow birch. After 5 years, treated areas contained 21 000 to 48 300 seedlings\/ha at Duchesnay compared with 5500 &#8211; 10 500 seedlings\/ha at Armagh. Significant losses of coniferous advance growth were observed at both sites, but a subsequent seedling recruitment occurred only at Duchesnay. Red spruce (<em>Picea rubens<\/em> Sarg.) showed superior establishment in the 60% cut (4400 seedlings\/ha) than under other cutting intensities (1600-2100 seedlings\/ha), whereas balsam fir (<em>Abies balsamea<\/em> (L.) Mill.) responded well to all partial cutting treatments. At both sites, pin cherry (<em>Prunus pensylvanica<\/em> L.f.) was the main competing species in the 100% cut, whereas densities of the preestablished mountain maple (<em>Acer spicatum<\/em> Lamb.) and striped maple (<em>Acer pensylvanicum<\/em> L.) either remained the same or increased in the partial cuts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in Canadian Journal of Forest Research\u00a038: 317-330 This paper presents the 5 year results of different cutting intensities (removal of 0%, 40%, 50%, 60%, and 100% of the basal area) applied in two mixed yellow birch (Betula alleghaniensis Britt.) &#8211; conifer stands of eastern Qu\u00e9bec, Canada.
