Abstract

    Annual measurements of fall color and leaf drop to establish the timing of developmental events and trends, as a measure of forest condition (ie effects of stress events) and long-term changes (ie effects of global climate change).

Methods

  • Current Methods
    • Monitoring on Mount Mansfield
      • Started: 1992-07-15
      • Method Description: Sugar maple and yellow birch are monitored at 1400 and 2200 feet on Mansfield

    • Unnamed Method
      • Started: 1999-07-15
      • Method Description: Yellow birch and paper birch at 2600 feet on Mansfield were added to represent high elevation fall phenology.

    • Monitoring at Lye Brook
      • Method Description: Red maple at 1400 feet in the Lye Brook Wilderness Area was added as a southern Vermont monitoring site.

    • Unnamed Method
      • Started: 1995-07-15
      • Method Description: Red maple (male and female) and white ash are monitored at 1400 feet, only.

    • Crown metrics
      • Started: 1991-07-15
      • Method Description: Visual crown ratings are recorded on 5 trees and 5 saplings (same trees as for bud development ratings).

    • New color and leaf drop
      • Started: 1991-07-15
      • Method Description: Visual crown ratings consist of percent color other than green, transparency (%), dieback-loss of leaves (%).

    • Unnamed Method
      • Started: 1994-07-15
      • Method Description: Crown density measurement was added in 1994 as a way to better estimate leaf drop.

    • Unnamed Method
      • Started: 1991-07-15
      • Method Description: Initial crown ratings are recorded in July, then every other week until color and drop changes rapidly (end of September) when weekly measurements are made. Full leaf off density is used to calculate percent leaf drop at each visit.

    • Unnamed Method
      • Started: 2001-07-15
      • Method Description: New color and leaf drop methods added to existing methods for testing. Color based on % color visible regardless of leaf drop. Added % green. Leaf drop based on visual estimate rather than measures of density, transparency or dieback. Total of color, green and leaf drop to equal 100%.


Sampling Equipment

  • No sampling equipment recorded for this dataset

Site Characteristics

  • Site Description: Upper elevation site (2200 ft.) added in the Underhill State Park.



  • Site Description: West slope of Mount Mansfield in the Browns River watershed at low elevation site (1400 ft.) at the Proctor Maple Research Center,
