Current Methods

  • Sample Locations
    Started: 2012-08-13

    The majority of sample locations were established using a grid system at the scale of the entire SFMA area. Additional samples have been established in specific stands or forest areas, also on area specific grids. All sample locations are given and recorded using UTM coordinates in meters for UTM Zone 19 with reference to the North American Datum for 1983 (NAD83). If a sample location is substantially different (>30-50+ft) of the location given by the GPS unit (the catalogued location) the correct location should be recorded in the field. A minimum of 100 averaged readings must be taken. *Record the actual (not as planned) GPS coordinates as UTM northing and easting on the data sheet.

  • Finding/Marking the Sample Center:
    Started: 2012-08-13

    When approaching the GPS location, look for bark-scribed trees and witness tree tags as well as tree ID numbers in blue paint. Look for the rebar/steel center pin, plastic flagging may be visible on the pin or trees around it, the witness tree azimuths and distances can help in finding an obscured pin. If the plot center pin cannot be found, consider returning with a metal detector to find the pin if it became buried. Otherwise re-establish the plot center, marked with a rebar pin driven partly into the ground, based on tree azimuths and distances. Hang a long-tailed flag as close to the plot center as possible.

    Instrumentation: Garmin GPS unit with averaging capability, Spare Batteries, Suunto compass or mirror type sighting compass set for azimuths, Metal Detector, Flagging, Rebar Pin

  • Plot Perimeter
    Started: 2012-08-13

    Tree distance will be measured from plot center to the center side of the tree stump. Borderline 鈥渙ut鈥� trees will be marked with an 鈥淴鈥� at approximate DBH using blue tube paint.
