Abstract : The report is the twelfth of a series presenting results from an experimental and analytical investigation of the propagation of radio waves in tropical jungle environments. The objective of this program is to obtain and analyze information that is generally applicable to improving the development, design, and operation of short range communications systems for tropical jungle environments. The experimental work has been done in a tropical rain forest test area in southern Thailand. The work covered by this report is especially concerned with the conduct of a special forest survey of the tropical rain forest in the test area. The objective of this forest survey was to obtain more detailed data on the statistical parameters associated with the vegetation. Statistical data is presented on the distribution of tree heights, diameters at breast height, biomass, basal area, etc. (Author)
