From: Optimal plot design in a multipurpose forest inventory
The maximum number of trees in a plot, and average number of tally trees, borderline trees and subsample trees as a function of plot radius (m) with the two subsample tree selection strategies with fixed-radius (a), relascope (b) and concentric (c) plots. In relascope plots the variation within each relascope factor is due to varying maximum radius and in concentric plots the variation within each radius is due to varying diameter limit
