Tb197: Forest Biomass Estimates In Maine:Statewide, County, And Spatial, Kenneth M. Laustsen
Tb197: Forest Biomass Estimates In Maine:Statewide, County, And Spatial, Kenneth M. Laustsen
Technical Bulletins
In Maine, statewide biomass estimates have increased from 752 million dry tons in 1982 to 980 million dry tons in a 2003 estimate. These estimates are produced using Forest Inventory & Analysis (FIA) data collected during Maine’s periodic and now annualized inventory design. The Maine Forest Service began tracking and reporting on wood flows of biomass in 1986. For the last 20 years (1986–2005) the total annual harvesting of all products has ranged between 6 and 7 million cords, extracted from a standing inventory that is currently estimated to be 277 million cords. The objectives of this current study were …

Habitat loss and degradation are two of the most important factors leading to the imperilment of species worldwide including amphibians, but mechanisms underlying these changes are poorly understood. To understand the fitness potential of harvested forests, I conducted studies of a forest specialist, Rana sylvatica (Wood Frogs) and compared these results with those from identical studies with an open canopy specialist, R. pipiens (Northern Leopard Frogs) in response to an unharvested control and three forest harvesting treatments: clearcutting (with removal of all merchantable timber > 10 cm diameter), clearcutting with coarse woody debris retention, and partial harvesting with removal of < 25% canopy cover. First, I used radio-telemetry data collected on 72 adult R. …
