Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Past Methods (No longer in use)

  • Site checks
    Started: 1991-04-15
    Ended: 1996-12-31

    Site checks are more spatially dispersed, opportunistic visits to survey species not captured by other methods.

  • Active searches
    Started: 1991-04-01
    Ended: 1996-12-31

    Active searches involves visiting a localized area and turning over rocks and logs to identify amphibians.The number of individuals of each species found in a given area per time were recorded to provide a rough measure of species relative abundance

  • Night visits
    Started: 1991-04-01
    Ended: 1996-12-31

    Night time visits are made to selected sites to hear the calls. Time of year and weather conditions chosen to locate species not located using other methods

  • Opportunistic observations
    Started: 1996-12-31
    Ended: 1996-12-31

    Accidental discoveries are recorded when a species is found that was not the target of another survey technique

Sampling Equipment

Equipment and software used to collect data, including how that equipment was used.

Current Equipment

  • Drift Fences
    Started: 1991-04-01

    At Mt. Mansfield, drift fences made of 50-foot sections of 20" wide metal flashing buried 4" below the ground surface at a height of 16" at right angles to each other. 2 sections were used at 1200' and 1600', one section at 3200'. Buckets are buried every 12.5' on both sides of the fence.

Site Characteristics

The spatial extent of the dataset site coverage, and descriptions of the spatial extent and context for the data collection

  • Site Description

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

    Minimum Altitude: 800 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
