DescriptionThe sample unit and its implications for the Forest Service, U.S. Department of Agriculture's Forest Inventory and Analysis program are discussed in light of a generalized three-dimensional concept of continuous forest inventories. The concept views the sampled population as a spatial-temporal cube and the sample as a finite partitioning of the cube. The sample serves to cut the volume of the cube into a finite number of pieces like a three-dimensional jigsaw puzzle. Each puzzle piece is defined by the spatial-temporal selection volumes of observation sets on the individual trees existing in the forest during the period of interest. The concept is developed as a temporal extension of the alternative view of forest sampling offered in Roesch et al. (1993).
