Title: Fact Sheet: Planting to restore ponderosa pine sites burned by high-severity fire.

Abstract: Increases in landscape-scale wildfires in frequent-fire for-ests over the last several decades have led to management concerns regarding long-term restoration of severely burned sites. In particular, interior areas of large, high-severity patches may lack conifer regeneration for decades (Savage and Mast 2005, Passovoy and Fulé 2006, Haire and McGarigal 2010, Roccaforte et al. 2012). A lack of tree regeneration may result in type conversion from sites historically dominated by coniferous forests to persistent non-forested areas (Figure 1) (Barton 2002, Strom and Fulé 2007). Based on these concerns, managers have at times aggressively pursued replanting of burned-over sites with conifers, with the result that many planted areas eventually become overly dense with trees to the point that eventually crown fires are bound to recur. To avoid this problem and to assure long-term restoration of forest structure including natural openings, consideration should be given to reestablishment of reference species composi-tion, natural ranges and variability in tree densities, and spatial arrangement of trees in a functional ecosystem.
