Tables included on this screen: inv-9a, inv-9b, inv-10a, inv-10b

Table inv-9a. Distribution-free tolerance limits (percent cover) for down wood > 12.5 cm (4.9 in) diameter and > 1.0 m (3.3 ft) long on all plots, with measurable down wood, by vegetation condition. The summaries are based on BLM, CVS, and FIA plots that are on the 5.5-km grid. If the number of plots with measurable down wood in a vegetation condition fell below 10, the cells are left blank.
