Fire occurrence data are required to conduct NFDRS2016 fire business analyses using FireFamilyPlus.

Fire occurrence is compared against calculated same-day fire danger values to find statistical relationships between fire activity and fire danger. This allows NFDRS2016 fire danger metrics to be used to help predict fire activity and related fire management business.

Fire occurrence data for federal agencies, and most states within the U.S., are available from multiple resources in a variety of file formats. There is no authoritative standard. There are also known data quality issues, which vary across the available corporate datasets. It can take an extensive amount of work to develop a fire occurrence dataset suitable for analysis.

For these reasons, it’s recommended that the Fire Program Analysis – Fire Occurrence Dataset (FPA FOD) be use for most historical fire business analyses. The FPA FOD is a national scale, quality controlled, consolidated dataset that draws from most of the available reporting systems. It is managed by Karen Short of the Rocky Mountain Research Station (RMRS), and is updated annually with an average of two years lag time. The current dataset contains data from 1996 through 2015, and has all the fields needed for a FireFamilyPlus fire business analysis.

The general process for using the FPA FOD in a FireFamilyPlus analysis is as follows:

  1. Obtain a FPA FOD dataset for 1992 thru 2015 for the entire United States.
  2. Use a spatial analysis tool or system (ArcGIS, AGOL, etc.) to import the QA/QC’d consolidated dataset and clip the data to the planning area or Fire Danger Rating Areas (FDRAs).
  3. In FireFamilyPlus, create custom agencies, units and sub-units as necessary to represent the planning area and/or any FDRAs.
  4. Organize the data by column identified by FireFamilyPlus in the data import function using Excel Spreadsheet, save as a .csv file.
  5. Import the final fire occurrence dataset into FireFamilyPlus, and associate the fires with one or more stations or SIGs.
Tech Tips for each of these steps AND for integrating more recent fire occurrence into an analysis will be posted here as they are updated, so please check back often for updates.

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.”

Read the complete LMC Equipment Bulletin 26-001, to learn more.

Intermediate Faller (FAL2) Position Task Book Update

Date:  July 24, 2026
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.

Equipment Advisory 26-001: Potential Front Driveline Joint Failure on 2018 and Earlier Ram Pickups

Date:  July 10, 2026
Questions? 
Please contact: Equipment and Technology Subcommittee

The Logistics/Equipment Management Committee (LMC) has released Equipment Advisory 26-001: Potential Front Driveline Joint Failure on 2018 and Earlier Ram Pickups. This advisory highlights multiple U.S. Forest Service regions reporting front driveline joint failure incidents.

This advisory recommends firefighters and fire managers to: 

  • Follow all Ram-issued inspection, maintenance, and service guidance for front driveline joints. 
  • Consider installing a driveline loop. 
  • Coordinate with fleet managers and service providers to determine the most appropriate driveline loop kit for each pickup.

For further details, please refer to the complete advisory.
