    Methods

    • Current Methods
      • Sample sites
        • Started: 1997-09-01
        • Method Description: Eight sites were selected on and near Mount Mansfield that had varying aspects, elevations and species compositions. Viewing locations were flagged for continuity. Measurements were recorded every 1-2 weeks from early September through October.

      • Unnamed Method
        • Started: 1999-08-01
        • Method Description: Measurements modified in 1999 so that % green, % color and % leaf drop total 100%.

      • Measurements
        • Started: 1997-09-01
