A presentation on Potential Operational Delineations (PODs) from multiple perspectives including both scientists and managers. We will discuss how PODs were used in Northern New Mexico past fire seasons where PODS were utilized; with an emphasis on PODs as a fire planning tool, new developments in research and applications, and innovations within the planning framework.

Description: Changing disturbance regimes and climate can overcome forest ecosystem resilience. Following high-severity fire, forest recovery may be compromised by lack of tree seed sources, warmer and drier postfire climate, or short-interval reburning. A potential outcome of the loss of resilience is the conversion of the prefire forest to a different forest type or nonforest vegetation. Conversion implies major, extensive, and enduring changes in dominant species, life forms, or functions, with impacts on ecosystem services. The webinar will synthesize a growing body of evidence of fire-driven conversion and our understanding of its causes across western North America. Increasing forest vulnerability to changing fire activity and climate compels shifts in management approaches, and we propose key themes for applied research coproduced by scientists and managers to support decision-making in an era when the prefire forest may not return.

For a decade, the Great Basin Fire Science Exchange (GBFSE) has supported fire, fuels, and restoration research and outreach in the region. We accelerate awareness, adoption, and implementation of fire science by providing a forum for managers, scientists, policy makers, and the public to interact and share. As one of 15 regional fire science exchanges sponsored by the Joint Fire Science Program, we organize and disseminate current research, make connections, and support long-term relationships between practitioners, managers, and researchers to improve the health of Great Basin ecosystems. From climate to communication, we’ve tackled the toughest issues facing managers and stakeholders in a stressed and changing environment. On our 10-year anniversary, we review our accomplishments and look to future challenges.
Weed-Suppressive Bacteria, or WSB, are bacteria strains of the soil bacterium Pseudomonas flourescens (D7, ACK55, and MB906) developed and marketed as a natural way to control exotic grasses, such as cheatgrass. In the late 1900s and early 2000s, scientists began experiments that looked for biological ways to selectively eliminate or inhibit growth of exotic annual grasses.
In 2009, new guidance for wildland fire management in the United States expanded the range of strategic options for managers working to reduce the threat of high-severity wildland fire, improve forest health and respond to a changing climate. Markedly, the new guidance provided greater flexibility to manage wildland fires to meet multiple resource objectives. We use Incident Status Summary reports to understand how wildland fire management strategies have differed across the western US in recent years and how management has changed since the 2009 Guidance for Implementation of Federal Wildland Fire Management Policy. When controlling for confounding variation, we found the 2009 Policy Guidance along with other concurrent advances in fire management motivated an estimated 27 to 73% increase in the number of fires managed with expanded strategic options, with only limited evidence of an increase in size or annual area burned. Fire weather captured a manager’s intent and allocation of fire management resources relative to burning conditions, where a manager’s desire and ability to suppress is either complemented by fire weather, at odds with fire weather, or put aside due to other priorities. We highlight opportunities to expand the use of strategic options in fire-adapted forests to improve fuel heterogeneity.
Description: Throughout the past 5 years, Gila County has been faced with record breaking wildfire activity. Learn how Gila County Emergency Management works with their Public Safety partners to overcome the challenges that come with Wildfire season. Acquire skills about planning tools such as the Gila County Community Wildfire Protection Plans (CWPP) and how you can help to protect your home and community from the ever evolving threat of wildfire, and the post-fire flooding events that follow.
Presenter: Carl Melford, Gila County Emergency Manager. After graduating from Globe High School in 2008, Carl began his public safety career as a Detention Officer with the Gila County Sheriff’s Office. Within his first 6 months of employment, Carl was promoted to Classification Specialist, and had written his first evacuation plan, all at the age of 18. In 2011, Carl graduated from the Southern Arizona Law Enforcement Training Center and was hired as a Police Officer with the Globe Police Department. During that time, His focus was on building resilient communities, and emergency planning. In 2015, Carl was hired by Gila County Emergency Management, where he began serving many roles in the Emergency Operations Centers across the state, as well as implementing Gila Counties own Emergency Notification Program. In 2017, Carl was promoted to Emergency Manager. Since then, Carl has taken pride in improving the mitigation, preparedness, response, and recovery capabilities of Gila County.

The National Native Seed Conference connects Research, Industry, Land Management, and Restoration professionals, providing the premier opportunity to develop relationships and share information about the collection, research and development, production, and use of native plant materials.
The 2023 National Native Seed Conference is dedicated to the science, practice, and policy of producing and effectively using native seed. The conference supports the America the Beautiful Executive Order, National Seed Strategy for Rehabilitation and Restoration, and the UN Decade on Ecosystem Restoration.
Conference sessions will cover several topics, including:
- Wild seed collection
- Seed production
- Industry opportunities and best practices
- Traditional Ecological Knowledge
- Evaluation and Research
- Seed Partnerships
- Wildlife and Pollinators

Reports from the early 1900s, along with paleo- and dendro-ecological records, indicate similar and potentially even larger wildfires over the past millennium, many of which shared similar seasonality (late August/early September), weather conditions, and even geographic locations. Consistent with the largest historical fires, strong east winds and anomalously dry conditions drove the rapid spread of high-severity wildfire in 2020. We found minimal difference in burn severity among stand structural types related to previous management in the 2020 fires. Adaptation strategies for similar fires in the future could benefit by focusing on ignition prevention, fire suppression, and community preparedness, as opposed to fuel treatments that are unlikely to mitigate fire severity during extreme weather. While scientific uncertainties remain regarding the nature of infrequent, high-severity fires in westside forests, particularly under climate change, adapting to their future occurrence will require different strategies than those in interior, dry forests.

This study used a coupled ecohydrologic and fire regime model to examine how climate change and CO2 scenarios influence fire regimes. In this semiarid watershed, we found an increase in burned area and burn probability in the mid-21st century (2040s) as the CO2 fertilization effect on vegetation productivity outstripped the effects of climate change-induced fuel decreases, resulting in greater fuel loading. However, by the late-21st century (2070s), climatic warming dominated over CO2 fertilization, thus reducing fuel loading and burned area. Fire regimes were shown to shift from flammability- to fuel-limited or become increasingly fuel-limited in response to climate change. We identified a metric to identify when fire regimes shift from flammability- to fuel-limited: the ratio of the change in fuel loading to the change in its aridity. The threshold value for which this metric indicates a flammability versus fuel-limited regime differed between grasses and woody species but remained stationary over time. Our results suggest that identifying these thresholds in other systems requires narrowing uncertainty in exogenous drivers, such as future precipitation patterns and CO2 effects on vegetation.
