Research article An example of the use of a two-phase sampling design for reconnaissance inventory in tropical forest
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. (no keywords)
