  (Résumé)

  Fast-growing hybrid poplars have been proposed as a means of achieving restoration objectives on former agricultural land by providing shelter for slower-growing species. Intensive two-stage scenarios of mixed plantations are also possible using valuable hardwoods interplanted among hybrid poplars. The latter would be harvested at maturity (approximately 20 years) once their protective role has been accomplished, leaving more space for the full development of the second cohort. We implemented simulations of hybrid poplar growth in the SORTIE-ND model and used it to test scenarios with clones varying in growth and crown allometry, different hardwood species, and spatial arrangements, to maximize production of both groups. Important differences in growth and allometry were manifested among clones over time, which translated into important differences in available light between rows. Sustained growth for most hardwoods appeared optimal using wider spacings of 16 m, compared with 12 m, between poplar rows. To our knowledge, this is the first attempt to integrate fast-growing hybrids and intensive silviculture scenarios into spatially explicit models. These models are necessary support tools for the efforts now being invested in intensive silviculture in the face of diminishing forest resources, increasing wood and fiber demands, and climate change.

  (Résumé)

  In southern Quebec, returning abandoned farmland to forest production presents a management opportunity. The shrub communities, which naturally colonize abandoned agricultural land, could be enriched by planting hardwood species that occurred in the precolonial forests. This study examines the growth of four hardwood species (Acer saccharum, Fraxinus americana, Prunus serotina, and Juglans nigra) planted on former pastures now covered by shrubby vegetation. Retaining part of this shrubby vegetation may produce improved growth in the planted trees. The experimental plantations were established in 1998 in two sites with different soil conditions and consisted of various treatments to control competition. Analyses seek to determine the effect of these treatments on (i) the light conditions, (ii) the cover of competing vegetation, and (iii) the growth and vigor of planted trees. Results show that increasing shrub clearing intensity has reduced the cover of tall competing vegetation after 5 years. However, light conditions and the cover of low competing vegetation around planted trees no longer vary significantly among treatments after 5 years. Strip clearing (SC) improved the growth of white ash and total clearing improved the growth of black walnut, with respect to site considered. Herbicide use was beneficial for the majority of species. SC presents a useful alternative for hardwood plantations. However, low competing vegetation control remains an important factor for increasing planted tree productivity in these managed shrub communities.

  (Résumé)

  Abstract - Underplanting early-successional forest stands with red oak and black cherry was tested as a way of improving productivity on abandoned agricultural land of North American temperate deciduous forests. A partial release treatment was applied during the third growing season and compared to a control. The growth increment after six years is analyzed with respect to treatment and competition layers. Although the release treatment reduced competition at all vegetation layers, growth was mostly determined by the density of the upper layer. Deer herbivory was not increased by the release. The release treatment succeeded in significantly increasing available light for the duration of the study, while the understory recovered quickly. Planted trees, particularly red oak, responded well to the release treatment. Results substantiate the need for dynamic silviculture in sensitive, rural landscapes, where conservation of forest structure is important. Résumé - Plantation sous-couvert de chêne rouge et cerisier tardif en forêt décidue pionnière d'Amérique du Nord.. Des chênes rouges et cerisiers tardifs ont été introduits sous couvert de jeunes peuplements d'origine agricole dans une étude visant l'amélioration de la productivité de peuplements pionniers de la forêt décidue tempérée d'Amérique du Nord. Un dégagement partiel appliqué au cours de la troisième saison de croissance est comparé à un témoin. La croissance après six ans est analysée en fonction du traitement et des strates de compétition. Alors que le traitement avait significativement diminué la compétition à tous les niveaux, la croissance était surtout fonction de la densité de la strate supérieure. L'herbivorie par le cerf n'a pas été augmentée par le dégagement. Le traitement de dégagement a significativement accru la lumière disponible pour toute la durée de l'étude, alors que le sous-étage s'est reconstitué rapidement. Les plants, particulièrement les chênes rouges, ont bien répondu au dégagement. Les résultats supportent une sylviculture plus dynamique dans les paysages ruraux sensibles, où la conservation des structures forestières est importante.

  (Résumé)

  We hypothesized that tree-based intercropping in southwestern Québec, Canada, would stimulate soil microbial activity and increase soil nutrient supply, thereby benefiting the growth of trees. Our experimental design comprised alternating rows of hybrid poplar (Populus nigra L. × P. maximowiczii A. Henry) and high-value hardwood species spaced 8 m apart, between which two alley treatments were applied 5–6 years after planting the trees. The first alley treatment consisted of a fertilized soybean (Glycine max (L.) Merr.) intercrop grown over two consecutive years, while the second consisted of repeatedly harrowing to minimize vegetation in the alley. Tree rows were mulched with a 1.5 m wide polythene mulch. Microbial respiration and biomass, and mineral N concentrations and mineralization rates were measured on five or six dates at 0, 2 and 5 m from hybrid poplar rows. On some of the sampling dates, we found significantly higher soil microbial biomass, mineral N concentrations and nitrification rates, and a significantly lower microbial metabolic quotient (qCO2), in the soybean intercropping than in the harrowing treatment. Over the 2 year period, hybrid poplar biomass increment and N response efficiency (NRE) were significantly higher (51 and 47%, respectively) in the intercropping than in the harrowing treatment. Microbial biomass and mineral N supply were significantly lower beneath the polyethylene mulch than in the alleys, and we posit that this may stimulate the growth of tree roots into the alley. We conclude that soybean intercropping improves nutrient turnover and supply for hybrid poplar trees, thereby increasing the land equivalent ratio (LER).
