Description: Advance regeneration is common under decadent, old-growth stands of California red fir (Abies magnifica A. Murr.). Intense competition for the site's resources can create sapling stands of poor vigor and advanced age. When competition is reduced by overstory removal and thinning, suppressed advance regeneration has been shown to respond with increased growth. But, to select leave trees, land managers need to know which tree characteristics we associated with growth after release and thinning. This paper reports those easily measured tree characteristics found to be most closely associated with growth after 8 years, on the Swain Mountain Experimental Forest in northeastern California.

Keywords: California red fir, Abies magnifica, advance regeneration, tree growth, damage, mortality
