bullet2 PLANTATION SAMPLE PLOTS

When making an inventory of plantations, strip plots and cluster plots may be used.  But if you have distinct compartments then it is probably more productive to set out a series of circular plots on a fixed bearing.  The bearing being decided in the office in order to lead the survey team through the main width of the compartment.  For compartments of less than around 50 ha around 8 plots is probably sufficient.  These can be supported by additional basal areas sweeps if the plot variation is extreme. For all inventory the required size of the sample can be calculated using standard formulae after an initial pilot sample had been done and the crop variation determined.
