Climate Change in the Lake Tahoe Basin

Climate change, Bark Beetles, Wildfire, and Fuel Treatment Effects in the Lake Tahoe Basin

Abstract: Managing large forested landscape in the context of changing climate regimes and altered disturbance regimes presents new challenges and will require an integrated assessment that incorporates forest disturbance, management, succession, and the carbon cycle. Successful management requires information about the inherent trade-offs among multiple objectives and improved awareness of the opportunities for spatially optimizing management on the landscape. We are evaluating the effects of fire suppression, wildfires, and forest fuel (thinning) treatments on the long-term potential for Lake Tahoe forests to sequester carbon in a global change context. We are also assessing the tradeoffs among management for C sequestration, mechanical fuel treatments, and stochastically recurring wildfires. Predicted changes in climate and ignition patterns will be simulated in response to future meteorological conditions, vegetation dynamics, and fuel treatments to examine the long-term effects on C emissions, forest structure, and forest composition.
