Table inv-3a. Distribution-free tolerance limits (trees per hectare) for snags > 25.4 cm (10.0 in) dbh and > 2.0 m (6.6 ft) tall on unharvested plots, with measurable snags, by vegetation condition. The summaries are based on all BLM and CVS plots (all grids), and no FIA plots. If the number of plots with measurable snags in a vegetation condition fell below 10, the cells are left blank.
