Abstract The adaptability of forests in the U.S. midwest to a changing climate is assessed. The forests of Missouri are simulated with a ‘forest-gap’ model, a stochastic model of the annual growth and mortality of trees within mixed-species forest plots. The development of representative forest plots under an analog climate like that of the 1930s is compared to development under baseline climate conditions. With no management response, average forest biomass in the region declines by 11% within ten years, primarily due to moisture-stress induced mortality. Longer term declines in forest productivity on the order of 30% are simulated. A variety of possible management responses through planting or harvesting practices were evaluated. None of these adaptations appear to be practical, although the salvage harvest of stressed trees would offset the economifc losses associated with the early mortality. An investigation of anticipated trends in the broader forest products sector suggests that opportunities for further adaptation to offset the decline in primary productivity of this region's forest are quite limited. However, a shift to wood powered electrical generation in the region might justify a level of management that would allow some adaptation to the analog climate change.
