Abstract: A two-phase stratified random sampling design (as developed by the United States Forest Service) was used in south-eastern Paraguay for a reconnaissance inventory to estimate areas and wood volumes over a region some 6 million ha in size. Details of its use are presented to illustrate the suitability of the design in forest areas where little prior information is available to assist inventory planning.
