• A Point Frame for Circular Plots in Southern Forest-Ranges for Plant Cover Estimates

      Baker, R. L.; Thomas, C. E. (Society for Range Management, 1983-01-01)
      A point frame has been modified to allow for plant cover estimates to a 152 cm height. Construction of a third crossmember that can be added to a 76-cm tall point frame allows sampling pins to be projected both upward and downward. Spacings between pins were changed to produce equal sampling areas while sampling circular plots. This design was tested with a miniature point frame on artificial plant populations and was shown to measure within +/- 5% of actual cover values.
