Methods

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

Current Methods

  • Large Sapling Plot: 26.3’ radius
    Started: 2015-06-01

    Each tree that is between >= 2.5” and <4.5 DBH is counted, species recorded, azimuth from plot center taken, the distance from plot center to the pith is measured and diameter at breast height, which is defined as 4.5’, is measured.

    Instrumentation: Hypsometer (Haglof Vertex IV), 100’ steel logger’s diameter tape, 100’ fiber glass ground tape, compass, bark scribe, blue paint pen, PVC pipe, orange, blue, and pink flagging, data collection sheets, pencils, Garmin gps

Sampling Equipment

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

Current Equipment

  • Large Sapling Plot: 26.3’ radius
    Started: 2015-06-01

    Each sapling that is recorded is scribed lightly with a bark scribe (2” long, ½” high) facing plot center and marked with the paint pen at 4.5’.

    Frequency: Each plot will be remeasured on a 7-year rotation following the original measurement protocols.
