Methods

  • Current Methods
    • Mean annual basal increment changes
      • Method Description: Raw data collected (1993) by Jeffrey Hughes to study changes in mean annual basal area increment (BAI) of canopy sugar maple trees growing at and below the species' elevation limit on Five Vermont mountainsides, in 5 year intervals, from 1963 to 1992.


  • Past Methods (no longer in use)
    • Sampling for differences in distribution
      • Started: 1992-06-01
        Ended: 1997-01-14
      • Method Description: Evaluation of sugar maple, yellow birch, paper birch and mountain birch on several Vermont mountains to measure differences in distriubtion as it relates to elevation-related climate.

    • Evaluation
      • Started: 1992-06-01
        Ended: 1997-01-14
      • Method Description: Overstory and understory individuals evaluated.

    • Composition of data
      • Started: 1992-06-01
