Old-Growth Characteristics Of Northern White-Cedar Stands, Nathan Wesely
Old-Growth Characteristics Of Northern White-Cedar Stands, Nathan Wesely
Electronic Theses and Dissertations
Northern white-cedar (Thuja occidentalis; hereafter white-cedar) communities have received relatively little research attention, and managers lack the tools used in the management of other commercial tree species. This includes the recognition of old-growth characteristics and the differentiation between old-growth and partially harvested stands, particularly in the context of Forest Stewardship Council (FSC-US) certification. Specifically, there is very little information about characteristics that define old-growth white-cedar stands despite the species’ abundance and wide distribution. Regional indices for late-successional or old-growth stands (Whitman and Hagan, 2007) do not include white-cedar. Forests dominated by white-cedar represent a type that currently lacks …
Spruce Grouse Habitat Ecology In Maine's Commercially Managed Acadian Forest, Stephen W. Dunham
Spruce Grouse Habitat Ecology In Maine's Commercially Managed Acadian Forest, Stephen W. Dunham
Electronic Theses and Dissertations
Spruce grouse (Falcipennis canadensis) inhabiting the mixed coniferous-deciduous forests of the northeastern United States are at the southern extent of their range. These mixed forests are known collectively as the Acadian forest and represent the transitional zone between the boreal forest to the north and the deciduous northern hardwoods forests to the south. Often assumed to be associated with mature, unharvested forest in this region, few studies have assessed habitat relationships of the species within areas dominated by commercial forest management. We investigated the influence of stand maturity, vertical and horizontal cover, and patchiness on the occupancy and …
