Methods

  • Current Methods
    • Fence locations
      • Started: 1991-04-01
      • Method Description: On Mansfield, drift fences located in the Browns River drainage. Two fences at 1200' (Proctor Maple Research Center) (1) in mixed northern hardwoods, (2) in hemlock stand; 2200' (off CCC road in Underhill State Park) in mixed northern hardwoods; and at 3200' (off Sunset Ridge Trail) in spruce and fir forest. No data collected in 2009.

    • Monitoring sites
      • Started: 2008-04-01
      • Method Description: At Lye Brook, monitoring restarted with three drift fences located outside of the north and south ends of wilderness area used for monitoring: 860' fence near Lye Brook Falls Access area, 2400' and 2700' fence off Branch Pond Road

    • Preparation and sampling
      • Started: 1991-04-01
      • Method Description: Drift fence bucket lids removed the day prior to anticipated heavy rain events, with samples collected after rain. Sampling done approximately 3 times per month, April through October.

    • Length measurements
      • Started: 1994-04-01
      • Method Description: At each drift fence, length measurements were taken only on the first three individuals from each size class and species. Total length of specimens measured from the tip of the nose to the tip of the body or tail. Snout-to-vent length also measured as length from tip of snout to vent or cloacal opening.


  • Past Methods (no longer in use)
    • Drift fence locations
      • Started: 1993-04-01
        Ended: 2002-10-31
      • Method Description: At Lye Brook, drift fences located outside of the north and south ends of wilderness area used for inventory: 860' fence near Lye Brook Falls Access area, 2400' and 2700' fence off Branch Pond Road.

    • Drift fence location distinction
      • Started: 1995-04-01
        Ended: 2002-10-31
      • Method Description: At Lye Brook, only the lower elevation drift fence (860') was used for inventory, the two upper elevation (2400' and 2700') were used for monitoring

Sampling Equipment

  • Drift fences, buckets, snake traps
    • Started: 1993-04-01
      Ended: 1995-10-31
    • Sampling Description: At Lye Brook, 3 drift fences constructed of straight sections of 30-meter lengths of aluminum flashing. 17-liter plastic buckets were placed at the end, with #10 tin cans with funnel tops in the middle. Screen "snake" traps also used.

Site Characteristics

  • Site Description: At Lye Brook Area, includes Lye Brook access area (840') and Branch Pond Road (2400' and 2700').

  • Minimum Altitude: 840 feet

  • Maximum Altitude: 2700 feet

  • Site Description: West slope of Mount Mansfield at 3 elevations: 1200', 2200' and 3200'

  • Minimum Altitude: 1200 feet

  • Maximum Altitude: 3200 feet
