Area burned by wildland fire has been increasing since the mid-1980s across much of the US. But the effects of fire on vegetation and soil – what we call burn severity or fire severity – is maybe the more important measure, ecologically speaking. Stand-replacing, or high-severity fire, for example, is more likely than low-severity fire to negatively impact ecosystems by increasing post-fire erosion potential, catalyzing conversions from forest to non-forest, and reducing carbon stocks. While high-severity fire has its place in the natural cycles of some ecosystems, it also can pose societal problems by jeopardizing human safety and infrastructure. In this webinar, we will briefly describe new approaches to mapping the severity of past fires using satellite imagery and cloud-based computing. The main focus of this webinar, however, will highlight recent advancements in modeling and predictive mapping of near-future burn severity; the mapped products predict the probability of high-severity fire, if a fire were to occur. Maps characterizing fire severity, whether they characterize past fires or represent predictions of the near-future, provide important information for managers and scientists who are tasked with managing fuel and wildland fire.

Major concerns after wildfires are the increased runoff and erosion due to loss of the protective forest floor layer, loss of water storage, and creation of water repellent soil conditions. To reduce the potential postfire erosion and flooding, various postfire mitigation treatments are commonly used on highly erodible areas when downstream values-at-risk are high. We have developed numerous online soil erosion prediction tools to allow for better post-fire land management decision-making. We have validated our model predictions with field studies throughout the Western US that encompass a range of rainfall regimes including monsoonal rains in the southwest (Arizona and New Mexico), thunderstorms in the Colorado Front Range and Northern Rockies, and wet frontal systems in Southern California and various erosion control treatments. For example, mulch treatments (agricultural straw, wood strands, wood shreds) reduce erosion and can be effective even for the higher intensity rainfall events. Our research results have brought a major shift in post-wildfire assessment methods and erosion management strategies.

Satellite data can provide weekly updates of phenology (NDVI, a measure of “greenness”) at a resolution of 15 acres. The PhenoMap web map was created to place these greenness images in an interactive format for managers to view local and regional changes in phenology. PhenoMap also helps to place current values of greenness in a historical context so managers can understand how this week’s value compares to previous year greenness values for the same week. In order to see how well the satellite data was capturing “green-up” and “brown-down”, satellite data was compared to cameras capturing changes in phenology in the various vegetation types of the western United States. Additional effort has also been made to compare the satellite data to grass development using rangelands in western South Dakota as a model grassland system. We will introduce the PhenoMap tool and share results from these validation efforts.

Prescribed fire can result in significant benefits to ecosystems and society. Examples include improved wildlife habitat, enhanced biodiversity, reduced threat of destructive wildfire, and enhanced ecosystem resilience. Prescribed fire can also come with costs, such as reduced air quality and impacts to fire sensitive species. To plan for appropriate use of prescribed fire, managers need information on the tradeoffs between prescribed fire and wildfire regimes. In this study, we argue that information on tradeoffs should be presented at spatial and temporal scales commensurate with the scales at which these processes occur and that simulation modeling exercises should include some realistic measure of wildfire probability. To that end, we synthesized available scientific literature on relationships between prescribed fire and wildfire regimes, and their associated ecological and societal effects, focusing specifically on simulation modeling studies that consider wildfire probability and empirical and modeling studies that consider prescribed fire and wildfire regimes at spatial and temporal scales beyond individual events.

Wildfire risk is shared across landscapes, ownerships, and administrative boundaries. Consequently, successful efforts to mitigate this risk depend on coordination of individual and collective actions across sets of public and private institutions and individuals associated with managing components of fire-prone landscapes. We need to understand how these diverse sets of actors, including individual residents, communities, non-profit organizations, and local, state, tribal, and federal agencies can and do interact and make decisions that affect fire and risk based on their rules, processes and social norms. Initiated in 2017, the Co-Management of Wildfire Risk Transmission Partnership (CoMFRT) brings together wildfire researchers, practitioners and decisionmakers to co-produce knowledge and actionable recommendations to support people and institutions successfully working together across scales and circumstances to best mitigate fire risk and build adaptation to wildfire. This presentation will provide an overview of the CoMFRT Partnership, key results and recommendations to date, and next steps all designed to underscore approaches for a variety of actors responsible for managing wildfire risk to better live with fire.

Last summer’s wildfire events impacted many Oregonians. These events reminded us of how important it is to plan and be prepared for wildfire. Planning and preparing for wildfire can feel like a massive endeavor. What can we do? Who can help? How do we continue to build wildfire adapted and prepared communities? Every community is unique; however, you are not alone. We can learn from our neighbors whether they are next door, across the state or even in a different state.
For this webinar, we invited our neighbors from southwest Colorado to tell us their story. Join us and learn how one community was affected by wildfires in 2002 and their journey to come together, rebuild, and take the action needed to save their lives and property from wildfire and the impact their actions had on wildfires in their neighborhoods since.
What you will learn:
– How other communities in the west have adapted to living in a wildfire environment
– Tools and resources available to help you prepare for wildfire
– How to engage your neighbors and build capacity to strengthen your wildfire adapted community

Dendrochronology: The trees that surround us have a story to tell, yet so many of us have no idea what that story is. What is dendrochronology? How old is the oldest recorded tree? Can trees get scars? Where are some of the oldest forests located? These are just some of the questions we aim to answer with our guest Dr. Justin DeRose, Assistant Professor of Silviculture and Applied Forest Ecology at Utah State University.

Description: The desert city of St. George, Utah is one of the fastest growing metropolitan areas in the country. Three federally listed endangered plant species that grow directly in the path of this juggernaut development are at extreme risk of further decline and possible extinction. With the help of drones, deep learning technology and innovative restoration methods, we are engaged in research and active management to give these unique and beautiful species a better chance at long-term survival.
