Methods
The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Current Methods
Fence locations
Started: 1991-04-01On 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: 2008-04-01At 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: 1991-04-01Drift 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: 1994-04-01At 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: 2002-10-31At 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: 2002-10-31At Lye Brook, only the lower elevation drift fence (860') was used for inventory, the two upper elevation (2400' and 2700') were used for monitoring
