The percentage cover (abundance), frequency of occurrence, biomass, species richness, and species diversity of understory herbs was measured on a paired watershed ecosystem in eastern Maine, USA. This paired watershed site (Bear Brook Watershed in Maine, BBWM) has had the West Bear Brook Watershed treated bi-monthly with granular ammonium sulfate at a rate of 28.8 kg S ha-1 yr-1 and 25.2 kg N ha-1 yr-1 since 1989. East Bear Brook Watershed serves as the reference site. More than 100 plots were randomly located across the two watersheds. The data suggest that there is generally a lower frequency of occurrence of …

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 …
