Seedling Counter Field Test
In 1990 and 1991, the USDA Forest Service's Missoula Technology and Development Center (MTDC) conducted field tests at several USDA Forest Service nurseries to demonstrate how its seedling counter can automate the inventory process. During field tests, the counter was used to inventory most pine species (Pinus spp.) as well as Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), California red fir (Abies magnifica A. Murr.), and Englemann spruce (Picea engelmannii Parry ex Engelm.). When inventories obtained with the seedling counter were compared to the those obtained by traditional hand-sampling methods, the seedling counter inventories consistently were within ± 10% of the nursery inventories for pine and fir species.
