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

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;
