Abstract

    Determine the distribution of areas sensitive to deposition of sulfur and nitrogen; determine the current status of sensitive areas utilizing atmospheric deposition of nitrogen; determine the degree of base cation leaching and aluminum mobilization (use soil, vegetation, land use history assocations to identify impacts); verify deposition thresholds; and assess impacts to terrestrial and aquatic ecosystems if under the PSD process.

Methods

  • Current Methods
    • Sample collection and analysis
      • Method Description: Samples were collected biweekly. pH measurements are then taken. Samples were transported to a lab for NH4+ and DOC analyses. Other stream chemistry measurements include Cl, Mg, Na, Al, Ca, K, H, NO3, SO4, Fe, Mn, and ANC. Soil water measurements included all of the above besides ANC.

    • Soil nitrification data
      • Method Description: Soil nitrification data collection used the buried bag method plus 2' PVC tubes with 3 in each forest type. Three lysimeters were installed in organic and B horizons in each forest type. Soils and vegetation were characterized at the intensive soil chemistry sites.

    • Unnamed Method
      • Method Description: Stream sampling cut back to 4 sites every three weeks.

Site Characteristics

  • Site Description: Stream sampling initially at 9 sites: 3 on Lye Brook, 2 on tributaries to Lye Brook, 1 on stream on west slopes, 1 on tributary to Bourne Brook, 2 in wetlands near Lye Brook Meadows. Soil nitrification sites in paper birch/red maple stand, sugar maple/spruce/birch stand and in spruce adjacent to a bog. These sites located left center of Lye Brook Wilderness Area (north of Lye Brook Trail and west of Bourn Pond Shelter).
