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.
