Fire has always been a part of life in southern California. Climate change and current fire management practices have led to catastrophic losses and impacts to human health, infrastructure and ecosystems, as seen, for example, in the 2018 Montecito debris flow. Indigenous wisdom instructs that rather than suppressing fire, we should seek to be in good relationship with fire. This project centers the voices of Chumash people by revitalizing their good relationship with fire in Chumash homelands. This revitalization comes at a critical time for both fire management and revitalization of Indigenous cultural burning practices in the southwest. The project will enable the recovery and documenting of Chumash knowledge...

Maintaining the native prairie lands of the Northern Great Plains (NGP), which provide an important habitat for declining grassland species, requires anticipating the effects of increasing atmospheric carbon dioxide (CO2) concentrations and climate change on the region’s vegetation. Specifically, climate change threatens NGP grasslands by increasing the potential encroachment of native woody species into areas where they were previously only present in minor numbers. This project used a dynamic vegetation model to simulate vegetation type (grassland, shrubland, woodland, and forest) for the NGP for a range of projected future climates and relevant management scenarios. Comparing results of these simulations illustrates...

Climate change is causing an increase in the amount of forested area burned by wildfires in the western U.S. The warm, dry post-fire conditions of the region may limit tree regeneration in some areas, potentially causing a shift to non-forest vegetation. Managers are increasingly challenged by the combined impacts of greater wildfire activity, the significant uncertainty about whether forests will recover, and limited resources for reforestation efforts. Simultaneously, there has been an increased focus on post-fire reforestation efforts as tree planting has become a popular climate change mitigation strategy across the nation. Therefore, with increased interest and need, it is crucial to identify where varying...

The 2017 fire season in California was highly unusual with its late seasonal timing, the areal extent it burned, and its devastation to communities. These fires were associated with extreme winds and were potentially also influenced by unusually dry conditions during several years leading up to the 2017 events. This fire season brought additional attention and emphasized the vital need for managers in the western U.S. to have access to scientific information on when and where to expect dangerous fire events. Understanding the multiple factors that cause extreme wildfire events is critical to short and long-term forecasting and planning. Seasonal climate measures such as temperature and precipitation are commonly...

Wildfire, drought, and insects are reshaping forests in the Western United States in a manner that is being exacerbated by warming temperatures. Disturbance events such as these can significantly alter the amount of land that is covered by forest in an area or region. Consequently, changes in forest cover from disturbance can impact water runoff conditions leading to dangerous flooding, erosion, and water quality issues. These events can be costly for society. In response, many land managers are using forest thinning and prescribed burning practices to reduce disturbance impacts, especially those that are caused by high-severity wildfire. In contrast to the wealth of research on the advantages of forest thinning...
Abstract (from http://www.bioone.org/doi/abs/10.3417/2017006): The Earth system is undergoing rapid, profound anthropogenic change. The primary axes of change include not only the climate system, but also the spread of invasive species, altered biogeochemical and hydrological cycles, modified disturbance regimes, and land degradation and conversion. These factors are influencing the distribution of species and the structure and function of ecosystems worldwide, interacting with climatic stressors that may preclude the persistence of many current species distributions and communities. Ecological disturbances such as wildfires and insect outbreaks can interact with climate variability to precipitate abrupt change...
Exposure (vulnerability) index for the future time period (2061-2080) representing projected climate conditions from the Meteorological Research Institute's Coupled Atmosphere-Ocean General Circulation Model, version 3, and the rcp85 emissions scenario. The exposure model uses LANDFIRE vegetation data and Worldclim climate data .The raster values represent exposure scores for the corresponding vegetation type. The modeled vegetation types can be spatially associated with the exposure values by overlaying them with the "landfire_veg_sw_300m.tif" raster.Exposure values represent where the location falls in climate space relative to its recent historical distribution:5 (core 5% of historical climate space); 10 (5 -...
Abstract (from SpringerOpen): Wildfires in the Pacific Northwest (Washington, Oregon, Idaho, and western Montana, USA) have been immense in recent years, capturing the attention of resource managers, fire scientists, and the general public. This paper synthesizes understanding of the potential effects of changing climate and fire regimes on Pacific Northwest forests, including effects on disturbance and stress interactions, forest structure and composition, and post-fire ecological processes. We frame this information in a risk assessment context, and conclude with management implications and future research needs. Large and severe fires in the Pacific Northwest are associated with warm and dry conditions, and such...

In Alaska, recent research has identified particular areas of the state where both a lack of soil moisture and warming temperatures increase the likelihood of wildfire. While this is an important finding, this previous research did not take into account the important role that melting snow, ice, and frozen ground (permafrost) play in replenshing soil moisture in the spring and summer months. This project will address this gap in the characterization of fire risk using the newly developed monthly water balance model (MWBM). The MWBM takes into account rain, snow, snowmelt, glacier ice melt, and the permafrost layer to better calculate soil moisture replenishment and the amount of moisture that is lost to the atmosphere...

First, we would like to thank the wildland fire advisory group. Their wisdom and guidance helped us build the dataset as it currently exists. This dataset is comprised of two different zip files. Zip File 1: The data within this zip file are composed of two wildland fire datasets. (1) A merged dataset consisting of 40 different wildfire and prescribed fire layers. The original 40 layers were all freely obtained from the internet or provided to the authors free of charge with permission to use them. The merged layers were altered to contain a consistent set of attributes including names, IDs, and dates. This raw merged dataset contains all original polygons many of which are duplicates of the same fire. This dataset...

Drought and wildfire pose enormous threats to the integrity of natural resources that land managers are charged with protecting. Recent observations and modeling forecasts indicate that these stressors will likely produce catastrophic ecosystem transformations, or abrupt changes in the condition of plants, wildlife, and their habitats, in regions across the country in coming decades. In this project, researchers will bring together land managers who have experienced various degrees of ecosystem transformation (from not yet experiencing any changes to seeing large changes across the lands they manage) to share their perspectives on how to mitigate large-scale changes in land condition. The team will conduct surveys...

The sky island forests of the southwestern United States are one of the most diverse temperate forest ecosystems in the world, providing key habitat for migrating and residential species alike. Black bear, bighorn sheep, mule deer, and wild turkey are just a few of the species found in these isolated mountain ecosystems that rise out of the desert landscape. However, recent droughts have crippled these ecosystems, causing significant tree death. Climate predictions suggest that this region will only face hotter and drier conditions in the future, potentially stressing these ecosystems even further. Simple models predict that vegetation will move to cooler and wetter locations in response to this warming. However,...
Abstract (from http://onlinelibrary.wiley.com/doi/10.1002/gdj3.47/abstract): Two datasets of soil temperature observations collected at Norman, Oklahoma, USA, were analysed to study horizontal and vertical variability in their observations. The first dataset comprised 15-min resolution soil temperature observations from 20 September 2011 to 18 November 2013 in seven plots across a 10-m transect. In each plot, sensors were located at depths of 5, 10, and 30 cm. All seven plots observed fairly consistent maximum soil temperature observations during the spring, fall, and winter months. Starting in late May, the observed spread in soil temperatures across the 10-m transect increased significantly until August when the...

Climate projections for the southern Great Plains, and elsewhere in the U.S., indicate that a hotter future with changes in precipitation amount and seasonality is to be expected. As plants become stressed from these changes, wildfire risk increases. One of the most valuable approaches to reducing the impacts of wildfires is fuel reduction through prescribed burns. Fuel reduction helps minimize the destruction of ecological communities, threats of future flooding, and extensive damages by lessening the intensity of future wildfires. Although safe burning practices can largely minimize the risks, prescribed burns may bring some degree of concern among practitioners. The real and perceived risks may include bodily...

As the National Climate Adaptation Science Center (CASC) develops a strategic effort around fire science, there is a critical need to develop a national-scale synthesis effort that identifies key regional CASC activities previously conducted, as well as major science gaps that may be addressed by a coordinated CASC network approach. The North Central CASC postdoctoral fellow will play a leadership role in the National CASC Climate Adaptation Postdoctoral (CAP) Fellows Future of Fire cohort to help identify the common efforts and leveraging points to shape the national-scale synthesis. Currently there is limited North Central CASC supported fire science available for the North Central region. To meet this need,...
