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.
