Faculty Opinions recommendation of Managing for multiple resources under climate change: national forests.

Abstract Climate change presents a novel and significant threat to the sustainability of forest ecosystems worldwide. The United States Forest Service (USFS) has conducted climate change vulnerability assessments for much of the 193 million acres of national forest lands it manages, yet little to no research exists on the degree to which management units have adopted considerations of climate change into planning or project implementation. In response to this knowledge gap, we piloted a survey instrument in USFS Region 1 (Northern region) and Region 6 (Pacific Northwest region) to determine criteria for assessing the degree to which national forests integrate climate-change considerations into their management planning and activities. Our resulting climate-change adaptation index provides an efficient quantitative approach for identifying where, how, and, potentially, why some national forests are making more progress toward incorporating climate-change adaptations into forest planning and management. Study Implications We used a self-assessment survey of planners and managers on US National Forests in Forest Service Regions 1 and 6 to design a climate change adaptation index for measuring the degree to which national forests units have integrated considerations of climate change into their planning and management activities. Our resulting index can potentially be used to help understand how and why the USFS’s decentralized climate-change adaptation strategy has led some national forests to make comparatively significant progress towards adapting to climate change while others have lagged behind.

The Future

Climate change, with warming temperatures and shifting precipitation patterns, may increase natural-caused forest fire activity. Increasing natural-caused fires throughout western United States national forests could place people, property, and infrastructure at risk in the future. We used the fine K nearest neighbor (KNN) method coupled with the downscaled Multivariate Adaptive Constructed Analogs (MACA) climate dataset to estimate changes in the rate of natural-caused fires in western United States national forests. We projected changes in the rate of minor and major forest fires from historical (1986–2015) to future (2070–2099) conditions to characterize fire-prone national forests under a range of climate change scenarios. The results indicate that climate change can add to the occurrence of forest fires in western United States national forests, particularly in Rocky Mountain, Pacific Southwest, and Southwestern United States Forest Service regions. Although summer months are projected to have the highest rate of natural-caused forest fire activity in the future, the rate of natural-caused forest fires is likely to increase from August to December in the future compared to the historical conditions. Improved understanding of altered forest fire regimes can help forest managers to better understand the potential effects of climate change on future fire activity and implement actions to attenuate possible negative consequences.

The Adaptation Resources for Agriculture Workbook was jointly developed by USDA Climate Hubs and NRCS to support producers, service providers, and educators to manage climate change. The workbook helps producers consider both short-term adaptive management actions (<5 yrs) and long-range strategic plans (5 to 20 yrs, subject to farm type). This workbook pro-motes adaptation through multiple resources including a “menu” of adaptation strategies/approaches and example tactics for cropping and forages, confined livestock, grazing, orchards and small fruit and vegetable production systems. Recent efforts by USDA Climate Hub NRCS Liaisons work to increase the number of examples, and have been documented as Case Studies. These Case Studies are of producers utilizing the 5-step process in the workbook to document their management choices to ameliorate climate change impacts to their operations.

Chemical Transport Model

Abstract. Almost USD 3 billion per year is appropriated for wildfire management on public land in the United States. Recent studies have suggested that ongoing climate change will lead to warmer and drier conditions in the western United States, with a consequent increase in the number and size of wildfires, yet large uncertainty exists in these projections. To assess the influence of future changes in climate and land cover on lightning-caused wildfires in the national forests and parks of the western United States and the consequences of these fires on air quality, we link a dynamic vegetation model that includes a process-based representation of fire (LPJ-LMfire) to a global chemical transport model (GEOS-Chem). Under a scenario of moderate future climate change (RCP4.5), increasing lightning-caused wildfire enhances the burden of smoke fine particulate matter (PM), with mass concentration increases of ∼53 % by the late 21st century during the fire season in the national forests and parks of the western United States. In a high-emissions scenario (RCP8.5), smoke PM concentrations double by 2100. RCP8.5 also shows enhanced lightning-caused fire activity, especially over forests in the northern states.
