Determining Atmospheric Deposition Inputs To Two Small Watersheds At Acadia National Park, Sarah J. Nelson
Determining Atmospheric Deposition Inputs To Two Small Watersheds At Acadia National Park, Sarah J. Nelson
Electronic Theses and Dissertations
Two small upland watersheds have been gauged and monitored at Acadia National Park since 1998. Cadillac Brook watershed burned in a wildfire in 1947. Hadlock Brook watershed has been undisturbed for several centuries, and serves as the reference site. Precipitation and throughfall volume and chemistry data have been collected using wetonly and continuously open collectors. Hydrologic and chemical inputs to the sites have been determined for each site. Differences in watershed and vegetation characteristics control the input of water and major ions to these watersheds. Vegetation type was the dominant control on enhancement of precipitation across the heterogeneous watersheds. Relative …
The Role Of Forest Soils In A Northern New England Effluent Management System, Leslie B. Nelson
The Role Of Forest Soils In A Northern New England Effluent Management System, Leslie B. Nelson
Electronic Theses and Dissertations
The Carrabassett Valley Sanitary District in Carrabassett Valley, Maine has utilized both a forest spray irrigation system and a Snowfluent™ system for the treatment of their wastewater effluent. This study was designed to evaluate potential changes in soil properties after approximately 20 years of treatment in the forested spray irrigation site and three years of treatment in the field Snowfluent™ site. In addition, grass yield and composition were evaluated on the field study sites. After treatment with effluent or Snowfluent™, soils showed an increase in soil exchangeable Ca, Mg, Na, and K, base saturation, and pH. While most constituents were …
Tb180: Baseline Data For Long-Term Forest Vegetation Monitoring At Bear Brook Watershed In Maine, J. D. Eckhoff, G. B. Wiersma
Tb180: Baseline Data For Long-Term Forest Vegetation Monitoring At Bear Brook Watershed In Maine, J. D. Eckhoff, G. B. Wiersma
Technical Bulletins
This report includes comprehensive information on the primary and meta forest vegetation data assembled from Bear Brook Watershed in Maine (BBWM). This information represents the first in-depth inventory of the forest vegetation, both woody and non-woody in multiple strata, within the two watersheds initially established at BBWM, West Bear and East Bear, and also the areas adjacent to the east and west of these watersheds. For long-term monitoring of vegetation responses to the continued manipulations and/or the recovery of the ecosystems at BBWM, access to the vegetation baseline information contained within this report is essential.
Relationships Between Rooting Restrictions, Radial Growth, And Drought Stress With White Pine (Pinus Strobus) Decline In Southern Maine, Megan L. Fries
Relationships Between Rooting Restrictions, Radial Growth, And Drought Stress With White Pine (Pinus Strobus) Decline In Southern Maine, Megan L. Fries
Electronic Theses and Dissertations
Throughout southern Maine there was a noticeable decline and mortality of white pine (Pinus sfrobus) from 1997 through 2000 in dense pole-size stands. The decline was widespread, scattered, and happened simultaneously indicating that it was incited by an abiotic stress. Because only isolated stands showed decline and mortality, site factors likely predisposed trees to injury. Site factors are likely related to the widespread field abandonment that took place throughout southern and central Maine, and led to establishment of pure white pine stands in many areas. Although white pine can regenerate on many sites, some locations will have soil limitations, such …
