Stonewall Ecology and Successional Landscapes

Examining the potential ecological correlations of wildlife presence and successional landscape in New England stonewall ecosystems.

stonewalls in new england
Stonewalls In New England
  • Estimated between100,000-250,000 miles of stonewall in New England
  • Constructed during pastoral clearing by early settlement
samuel a tamposi water supply reserve satwasr
Samuel A. Tamposi Water Supply Reserve (SATWaSR)
  • In 2001 the Town of Barrington, NH acquired ~1,400 acres of land in the southeast corner of town
  • A“bargain sale” from the TamposiCorporation, the owners,
  • A grant facilitating the acquisition from the N.H. Department of Environmental Services “Water Supply Protection Program.”
research proposal
Research Proposal
  • Problem Statement:

Research and analyze the potential ecological impacts on the surrounding ecosystems in different successional phases.

  • Research Question
  • Hypothesis
  • Materials
  • Methodology
objectives
Objectives
  • Survey stonewalls for wildlife usage.
  • Classify vegetation communities into successional phases.
  • Measure abiotic and biotic characteristics and compare within the different successional phases.
  • Analyze data to build connections between the successional characteristics and wildlife presence.
research question
Research Question
  • What correlations exist between small mammal usage of stonewalls with vegetative communities and physical environmental characteristics (temperature, rainfall, etc.)?
hypothesis
Hypothesis
  • Original Hypothesis

Small mammal usage in the Tamposi will be greater in late successional ecosystems due to cover provided by stonewalls and the development of vegetation in the surrounding ecosystem.

  • Alternative Hypothesis

Small mammal usage in the Tamposi will be greater in early successional ecosystems due the ease of travel that less vegetation provides.

successional phases
Successional Phases
  • Huston and Smith’s (1987) compilation of physiological and life-history characteristics of early and late successional plants was used to define characteristics of each phase.
      • The characteristics from Huston and Smith that were considered included shade tolerance, growth rate, relative mature size, and maximum life span.
species composition
Species Composition
  • Common tree species within the Tamposi were categorized by genus;
      • Hemlock (Tsuga spp.)
      • Pine (Pinus spp.)
      • Maple (Acer spp.)
      • Beech (Fagus spp.)
      • Oak (Quercus spp.)
      • Birch (Betula spp.)
      • Witch-hazel (Hammamelis spp.).

Setting Up the Site
  • Measured and a 10 meter transect along stonewall at all four Successional Sites
  • Marked points at each end
  • Marked center point;
