Abstract:
... White spruce (Picea glauca) is commonly planted in timberlands of the upper Great Lakes region. Genetically improved seed, sourced from selected genotypes and propagated in seed orchards, is a primary seed source for artificial regeneration. Volume improvements gained by planting selected genotypes of Picea glauca sources range from 9 to 30 %; however, tradeoffs associated with selection for volum ...

Abstract:
... Northern white-cedar (Thuja occidentalis L.) wetlands are highly valuable both commercially and as wildlife habitat. However, northern white-cedar forested wetlands are declining in area from forestry activities and development, with mitigation efforts often failing to reproduce these ecosystems. For this reason, the goal of this project was to determine the feasibility of creating a northern whit ...

Abstract:
... This review examines the published work on bareroot and container stocktypes in forest restoration programs. The objective was to define overall trends between these two stocktypes and describe what they mean in terms of available information on their nursery and field performance. Stock quality assessments show bareroot seedlings have larger shoot systems because they are typically grown at lower ...

Abstract:
... Restoration of degraded pasture lands in the tropics through afforestation is widely supported. The greatest obstacle to afforestation, however, is the long delay before initial financial returns from wood harvesting are realized. Interplanting young trees with food or energy crops has been proposed as a strategy to help overcome this obstacle. We investigated the impact of this practice on the su ...

Abstract:
... Post planting assistance techniques during early ontogeny may be a determining factor for tree survival in stressful habitats. In the eastern region of NW Patagonia, stands of the fast-growing exotic conifers Pinus ponderosa (Ponderosa pine) and Pseudotsuga menziesii (Douglas fir) are being established in places which are currently, or were in the past, occupied by native Austrocedrus chilensis (m ...

Abstract:
... European and American chestnut species (Castanea) have been decimated by exotic species, most notably chestnut blight (Cryphonectria parasitica), since the early nineteenth century. Backcross breeding programs that transfer blight disease resistance from Chinese chestnut (C. mollissima) into American chestnut (C. dentata) offer promise for chestnut restoration, particularly for the American chestn ...

Abstract:
... Distinguishing the relative effects of above- and belowground competition can improve our understanding of the forces shaping community assembly in different ecosystems. In this study, we investigated the impacts of above- and belowground competition on seedling growth and allometry in a tropical monsoon forest (TMF) on Hainan Island, China. Four common dominant canopy tree species from three fore ...

Abstract:
... Despite several studies demonstrating that deep planting has no negative effects on seedling development, conifer seedlings are still typically planted to depths of 3–5 cm in boreal forests. Planting machines plant seedlings deeper. While machine planting has become more common in boreal forests, there is still a need to demonstrate that conifer seedlings can be planted using this method without r ...

Abstract:
... Root deformation is a common challenge in container seedlings especially for vigorous-rooted tree species. The issue is significant for Chinese cork oak (Quercus variabilis Blume.) which is grown in cost-effective polybags. In this study we examined how copper root pruning and radicle pruning (1/3 or 2/3 of radicle length) individually and together (1/3 radicle pruning in combination with copper r ...

Abstract:
... Compared to enrichment planting techniques, direct seeding may represent a viable low-cost method to ensure the conservation and recovery of forest ecosystems. However, it is necessary to identify the environmental factors that affect seed germination and seedling establishment in order to improve the success of this technique. It has been suggested that the establishment of Oreomunnea mexicana (J ...

Abstract:
... Native tree seedlings (nursery produced) were planted under control and herbicide treatments in the understory of a mature hybrid poplar plantation, naturally invaded by glossy buckthorn, a major invasive exotic shrub of Eastern North America. The objectives were to (1) test the negative effect of the invasive buckthorn on seedling growth, (2) determine if this effect differed for two tree species ...
