Course Number
RX-510
Other Training Which Supports
Prescribed Fire Burn Boss Type 1 (RXB1)
Course Description

RX-510, Advanced Fire Effects, is a science-based course designed to support the integration of fire effects knowledge into land management programs. The course emphasizes the importance of considering fire effects in the design, implementation and monitoring of planned fire treatments over multiple spatial and temporal scales. In addition, many of the principles covered can be used to integrate fire effects in support of the wildfire decision-making process. This course recognizes that planning and implementing the use of fire in any capacity are independent activities, and provides opportunities for the burn boss and planner to work together. The course is an intensive session that provides college-level lectures, case studies, discussion groups, and testing procedures throughout the week. Instructors include agency and university scientists, agency resource specialists, and fire practitioners. Students have many opportunities to interact with the faculty. To successfully complete RX-510, students are required to complete the pre-course work and attend all sessions for the entire week. Students should expect long days. Class size is limited to 84 students.

LMC Equipment Bulletin 26-001: Aquatic Invasive Species – Seasonal Reminder for Mussels

Date:  July 30, 2026
Questions? 
Please contact: Equipment and Technology Subcommittee

The Logistics and Equipment Management Committee (LMC) issued Equipment Bulletin 26-001: Aquatic Invasive Species - Seasonal Reminder for Mussels, reminding the wildland fire community that aquatic mussels continue to be a problem. Mussels rapidly colonize hard and soft surfaces, including aquatic plants and fire equipment, clogging pipes, fouling motors, disrupting water systems, and impacting native species.

To help prevent their spread, fire personnel must follow the decontamination procedures outlined in the NWCG Guide to Preventing Aquatic Invasive Species Transport by Wildland Fire Operations, PMS 444. Additionally, report any sightings immediately to your Lead Resource Advisor and include clear, close-up photos (with a pen or your hand for size reference) and location details.”

Questions? 
Please contact: Tree Felling Subcommittee

NWCG Operations Management Committee (OMC) has issued an update to the NWCG Position Task Book for Intermediate Faller (FAL2), PMS 311-91. To ensure clarity for both trainees and evaluators, the updated FAL2 Position Task Book (PTB) explicitly states who is authorized to sign off on your tasks:

“Evaluators must be qualified as a FAL2, or an Advanced Faller (FAL1).”

If you are currently working out of a previously published version of the FAL2 PTB, you do not need to restart. However, OMC highly encourages you to take the following step to prevent any confusion in the field:

  • Print and replace the updated evaluator information page (page 2) in your current physical PTB.
