Herbaceous weed control (HWC) is prescribed for growing season control of vegetative competition in hardwood afforestation attempts on former agricultural areas. Without HWC, planted seedlings often exhibit poor growth and survival. While currently employed HWC methods are proven, there is a substantial void in research comparing HWC treatments spanning multiple years. A total of 4,320 bare-root seedlings of three oak species were planted on three Mississippi sites. All sites were of comparable soils and received above average precipitation for the majority of the three-year study. Eight combinations of HWC and mechanical site preparation were utilized at each site, with 480 seedlings planted in each of the nine blocks, and a total of 1,440 seedlings per species planted across all sites. Treatments were installed on 3.1 m centers, with mechanical treatments as follows: control, subsoiling, bedding, and combination plowing. HWC treatments included one and two-year applications of Oust ® XP. Treatments were applied over seedlings post-planting in 1.5 m bands, at a rate of 140.1 g product/hectare. Excepting one species, HWC dependent height or groundline diameter differences were not detected among mechanical treatments, species, HWC regime, or combinations thereof. No survival differences were observed among site preparation treatments or species. However, analysis detected a growing season/HWC treatment interaction for seedling survival.

“…Scarcity of postagricultural herbaceous competitors and abundant tree growing stock both contributed to a favorable competitive environment for tree species relative to the more typical bottomland forest recovery scenarios in this region (Kruse and Groninger, 2003;Baer and Groninger, 2004;Groninger et al, 2004). Significantly less herbaceous cover in undisturbed and transition areas versus wind and wind + salvage areas likely resulted from the uninterrupted presence of at least partial canopy cover in the former.…”

“…During the posttreatment years, vegetation composition can partially or totally differ from the original (Dreyfus 1984, Willoughby andMcDonald 1999). This phenomenon is normally very favourable for tree seedling growth, but in certain cases the new vegetation composition enhanced competition (Horseley 1988, Groninger et al 2004). However, in most situations herbicide application has a greater impact on relative species dominance than on species composition or diversity (Boyd et al 1995, Miller et al 1999, Sullivan and Sullivan 2003.…”

Chemical and mechanical forest vegetation management (FVM) treatments are analyzed and compared to assess which is the most sustainable in intensively managed plantations in the context of the TRIAD. At the biological and ecological level, herbicides have been found to have more impacts on flora and fauna compared to mechanical treatments, but the differences are of short duration. The effects of noise generated by manual or mechanical brushing on wildlife have not been investigated, however. Local application of herbicide at the base of the tree should further lower these impacts. At the social level, the general public has a negative perception of chemical treatments, while mechanical treatments are wellperceived. However, in terms of worker safety, chemical treatments are less risky than manual brushing (brushsaw or chainsaw). At the economic level, herbicides globally cost less and are more effective at increasing fibre production than mechanical operations. We conclude that it is difficult to assess globally what is the most sustainable option to control competing vegetation. However, the careful use of herbicide may be the most sustainable option if the added productivity thus obtained is used to increase protected areas and ecosystem-based management, as is intended with the TRIAD concept.Key words: forest vegetation management, chemical release, mechanical release, functional zoning, plantations, ecological impacts, social impacts, economical impacts, intensive management, sustainable forestry RÉSUMÉ Les traitements chimiques et mécaniques de gestion de la végétation compétitrice sont comparés afin d'évaluer quel traitement est le plus durable pour réaliser le dégagement des plantations à haut rendement dans le contexte de la TRIADE. Au niveau écologique et biologique, les traitements chimiques ont plus d'impacts négatifs sur la faune et la flore que les traitements mécaniques, mais cet impact est de courte durée. Les effets du bruit sur la faune généré par l'utilisation de la débrousailleuse ou de la machinerie lourde ne sont pas documentés. Un dégagement chimique local, à la base de chacun des semis, réduit considérablement les impacts écologiques associés aux phytocides. Au niveau social, la perception à l'égard du dégagement chimique est fort négative, ce qui n'est pas le cas pour les opérations mécaniques. En matière de santé sécurité des travailleurs, l'usage de phytocide est moins risqué que le dégagement mécanique manuel. Pour ce qui est des bénéfices économiques, comparativement au de dégagement mécanique, l'utilisation de phytocides chimiques est moins coûteuse en plus d'augmenter de manière plus importante le capital ligneux. Nous concluons qu'il est difficile de discriminer quel traitement est le plus durable. Néanmoins, l'usage rationnel de phytocide apparaît comme l'option la plus durable dans la mesure où l'augmentation de la production ligneuse pourrait ensuite servir à l'implantation d'un aménagement écosystémique et à la création d'aires protégées, comme le concept de TRIADE le ...
