This data publication contains seedling density, sapling density and variable plot radius tree data associated with the Tenderfoot Creek Research Project sampled between 1997 and 2007. Experimental shelterwood harvests combined with prescribed burning were implemented in the Tenderfoot Creek Experimental Forest between 1999 and 2003. These data contain pre- and post-treatment data. Post-treatment sampling occurred three-, four-, and in some cases seven-years after thinning and burning treatments. In addition to seedling and sapling densities, tree data include height, bole diameter, damage, vigor, condition (live or dead), crown position and crown depth. Species measured include lodgepole pine (Pinus contorta), subalpine fir (Abies lasiocarpa), Engelmann spruce (Tsuga engelmannii) and whitebark pine (Pinus albicaulis).
