Inventory of microsites on clearcut and downed forest hillslopes of Mount St. Helens Blast Zone. To obtain average areas (for stumps and rootwads) and dbh's (for snags) of certain microsites for each hillslope site. To obtain aerial vegetation cover by species, by microsite substrate, and by shade class for each plot.
