Abstract

We evaluated the impacts of climate change on the productivity and health of a forest in the mixed-conifer region in California. We adapted an industry-standard planning tool to forecast 30-years of growth for forest stands under a changing climate. Four projections of future climate (two global climate models and two emission forecasts) were examined for forests under three management regimes. Forest structural and tree demographic data from the Blodgett Forest Research Station in El Dorado County were used to fit our projections to realistic management regimes. Conifer tree growth declined under all climate scenarios and management regimes. The most extreme changes in climate decreased productivity, as measured by stem volume increment, in mature stands by 19% by 2100. More severe reductions in yield (25%) were observed for pine plantations. The reductions in growth under each scenario also resulted in moderate increases in susceptibility to non-catastrophic (i.e., non fire) causes of mortality in white fir (Abies concolor). For the worst case, median survival probability decreased from the baseline rate of 0.997 year-1 in 2002 to 0.982 year-1 by the end of the century.
