Wildland fire managers in the United States currently utilize the gridded forecasts from the National Digital Forecast Database (NDFD) to make fire behavior predictions across complex landscapes during large wildfires. However, little is known about...
Shifting climates and annual grass invasions have contributed to the increased number and size of fires in the western United States costing millions of dollars in fire suppression and post-fire rehabilitation. Post-fire rehabilitation implements fuel...
Predicting wind-driven rate of fire spread (RoS) has been the aim of many studies. Still, a field-tested model for general use, regardless of vegetation type, is currently lacking. We develop an empirical model for wind-aided RoS from laboratory fires...
As scientists and managers seek to understand fire behavior in conditions that extend beyond the limits of our current empirical models and prior experiences, they will need new tools that foster a more mechanistic understanding of the processes...
Large outdoor fires present a risk to the built environment. Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the world, and are an emerging problem in fire safety...
Data-driven wildfire spread modeling is emerging as a cornerstone for forecasting real-time fire behavior using thermal-infrared imaging data. One key challenge in data assimilation lies in the design of an adequate measure to represent the...
A 3D multi-physical model referred to as 'FireStar3D' has been developed in order to predict the behavior of wildfires at a local scale (<500 m). In the continuity of a previous work limited to 2D configurations, this model consists of solving the...
The paper reports visualization of the flow of smoke over a flat surface inside of a low-speed wind tunnel. A heating plate flush mounted on the wind tunnel floor simulated a spreading line fire that produces uniform heat flux under constant wind speed...

We are looking for a new team member to manage projects to improve wildfire resiliency and forest health, including vegetation management for defensible space for properties and emergency evacuation/access routes, and coordinating the Fire Safe Council for San Mateo County. The position is full-time at 40 hours per week. It is grant dependent, currently funded through 2020 with the intent to secure ongoing funding. The CPM will report to the Natural Resource Specialist and will work with other staff as needed to ensure the successful implementation of projects. The CPM will work closely with a broad array of partner organizations, government agency staff, and public and private landowners. It is expected that a new Conservation Project Coordinator will be hired to assist the CPM with program activities.
- Drives engine to fire locations, frequently over unimproved roads.
- Positions engine in appropriate locations in consideration of safety of crew and equipment, and how the equipment can best be used in control and mop-up operations.
- Starts pump engine, primes pump, adjusts engine speed and pump valves, lays hose, and uses appropriate nozzles and nozzle adjustment in effective use of water and additives.
- Has specialized duties such as water handling specialist, fully qualified chain saw operator, or responsible for maintenance of specialized equipment used to respond to wildland urban interface/intermix situations.
- Gathers and considers information on weather data, topography, fuel types, and fire behavior in responding to wildland fire incidents.
- Inventories fuel beds, prepares associated reports, performs hazard fuel reduction projects, monitors burning conditions, piles vegetation debris and acts in assigned positions such as ignition or holding specialist during actual fuel reduction efforts by prescribed fire.
- Performs project work such as road and trail maintenance, fuel bed inventory, habitat improvement, burned area rehabilitation, and miscellaneous equipment and facilities maintenance.
- Assists in the preparation of hazardous fuels treatment plans and burn plans.
Physical Demands: Essential functions require arduous exertion for protracted periods of time such as, but not limited to, extensive running, walking, climbing, kneeling, stooping, pulling hoses, jumping and twisting. Duties involve rigorous field work requiring above average physical performance, endurance and superior conditioning. Work requires prolonged standing, walking over uneven ground, and recurring bending, reaching, lifting and carrying of items weighing over 50 pounds and shared lifting and carrying of heavier items, and similar strenuous activities requiring at least average agility and dexterity. Duties include demands for strenuous activities in emergencies under adverse environmental conditions and over extended periods of time. Operation of some specialized fire equipment can place extended physical stress on employee during fire activities. The duties of this position require that the incumbent meet the arduous level of physical fitness as measured by the current physical fitness testing standards.
Work Environment: The work is primarily performed in forest and desert environments in steep terrain where surfaces may be extremely uneven, rocky, covered with thick tangled vegetation, smoky conditions, etc. Temperatures commonly exceed 100 degrees F and fall below freezing. Risks include smoke inhalation, fire entrapment, snake or insect bites and stings, exposure to excessive machinery noise, and falling and rolling material. Employee must adjust and cope with exposure to weather elements, dust and smoke, poor bivouac and eating situations under an unpredictable set of circumstances. Employee may be required to live in backcountry camps for extended periods of time. The hazardous nature of the work requires that personal protective equipment be worn (boots, hardhat, gloves, flame resistant clothing, etc.). Work may require travel by light fixed-wing or rotor-wing aircraft.

The Prescribed Fire Training Center (PFTC) is a unique program blending maximum field prescribed burning experience with a flexible curriculum of classroom instruction on foundational topics for prescribed fire practitioners.
The PFTC is headquartered in Tallahassee, Florida. Training locations are dispersed throughout Florida, Georgia, Mississippi, Alabama, Louisiana, North Carolina, and South Carolina. Attendees will travel to several remote sites during their stay to take advantage of prescribed burning and learning opportunities with a variety of agencies, fuel types, and challenges such as urban interface.
The Southeast is an ideal site for the PFTC due to the year round burning programs of several agencies, broad prescription windows, and the high level of interagency cooperation. During their 20 day tour, individuals should expect to participate in prescribed burns conducted for a variety of objectives. The wildland urban interface is a focus of PFTC, and most participants will have opportunities to conduct burns in interface situations. This variety of field experience with the different prescriptions, planning procedures, and techniques of the various agencies offers an accelerated learning opportunity for the participants.
