While inconvenient for your average hiker or boater, major shifts in the weather can be deadly for firefighters. Longer and more intense fire seasons make accurate and timely weather predictions crucial to firefighter safety. To answer this need, the Fire Weather Alert System (FWAS) was developed by Jason Forthofer, Research Mechanical Engineer, and Natalie Wagenbrenner, Research Meteorologist, both from the Rocky Mountain Research Station’s Missoula Fire Sciences Laboratory. The FWAS is a mobile app that gathers weather data from many sources into a single convenient space and provides firefighters with individualized, easy-to-use, and timely weather alerts on their phones.

In response to this event, Rocky Mountain Research Station’s (RMRS) fire management specialist Brad Pietruszka and colleagues wanted to understand how often fires like the Tamarack Fire occur, the driving factors behind the initial decisions in those fires, and, in turn, how they may feed the “let burn” misperception. With perspective as a fire manager, Pietruszka suspected a communication failure; and as a researcher, he turned to empirical research to investigate this question. “We wanted to see how often this type of outcome has occurred to understand what may be informing the ‘let burn’ dialogue,” Pietruszka says.

An often-overheard phrase, “there is no future without smoke,” describes fire, and associated smoke, as an ecological process inextricably tied to Western forests. While fire can provide many benefits such as reducing fuels and renewing forests, smoke from fires poses a serious challenge to public health, land managers, and air quality regulators. So, can we reduce these challenges?

Invasive annual grasses have long been known to increase wildfire danger in shrublands and woodlands of the American West. Ventenata (Ventenata dubia) is one such grass. First reported in North America in 1952 in Washington state, it is now expanding into previously invasion- resistant forest landscapes. Unlike cheatgrass, another invasive grass, ventenata can grow in sparsely vegetated rocky meadows. These forest scablands, often embedded within a forested landscape, have historically served as natural fire breaks. Lacking sufficient fuels, the scablands usually stopped fire from spreading into neighboring fireprone forests. However, when ventenata invades scablands and other open areas, it can create a highly flammable bridge between adjacent forested areas and act as a “ fire conveyor belt” that facilitates the spread of fire across a landscape.

Reducing PODs (potential operational delineations) to a network of suppression-focused fuel breaks may dilute the intent and diminish the richness of the framework. Using PODs and fuel breaks to perpetuate fire exclusion is not likely to be effective and may set us up for failure. In many forest types, we may need to rethink design of fuel breaks along POD boundaries to support expansion of proactive use of fire.

n early October 2023, nearly fifty research scientists and technicians collaborating with the USDA Forest Service-sponsored Fire and Smoke Model Evaluation Experiment (FASMEE) gathered on the Fishlake National Forest to collect measurements from a rare stand-replacing prescribed fire. Developing new approaches to predict fire and smoke behavior, scientists representing the USDA Forest Service, the National Aeronautics and Space Administration (NASA), Tall Timbers, Desert Research Institute, and universities from across the country, partnered to collect fire-related data from belowground to space. These synergistic research projects characterized fuels, measured radiant heat and energy, evaluated smoke concentrations, and documented fire effects on vegetation and even bats.

For nearly 12 years, the Field Guide for Mapping Post-Fire Soil Burn Severity has provided BAER teams with consistent methodologies, tools, and terminology to quickly and accurately identify postfire conditions. RMRS Research Engineer Pete Robichaud and colleagues created the field guide, which is now available in Spanish.

Imagine being able to take a bird’s eye view of the forest: you could see the forest structure, how the trees are grouped, the height and size of each tree in a matter of moments as you cruise over. You could fly over the stand today, then again next year and examine the effects of a treatment or a wildfire or an insect outbreak. Uncrewed aerial systems (UAS – aka drones) are starting to allow managers to do just that.

It is not well understood whether desert plantings can facilitate recruitment of other natives (or mainly just non-natives), or whether facilitation changes through time as a restoration site matures. To address these uncertainties, we partnered with the National Park Service to study plant community change below planted perennials and in interspaces (areas between perennials) during 12 years (2009-2020) in Joshua Tree National Park, California, in the southern Mojave Desert.
