LANL Details Wildfire Mitigation Work, Interagency Efforts on Pajarito Plateau

Three decades of fuel clearing, prescribed burns, firebreaks, and interagency coordination form the backbone of wildfire defense on the Pajarito Plateau, according to a detailed look at Los Alamos National Laboratory's mitigation efforts published this week.

The scope of that work spans canyons, corridors, and jurisdictional boundaries. The Los Alamos County Fire Department, which serves as an all-hazard municipal department providing wildland fire suppression for both the county and LANL, described its partnership with LANL's Wildland Fire Management Division as "very productive." The two agencies have collaborated on training for other federal agencies, given joint briefings to the DOE Field Office, and delivered joint public presentations. "LAFD will continue to seek out opportunities to work with LANL Wildland Fire Management in the future," according to the department's statement.

That collaboration has institutional roots going back to May 1996, when the Inter-Agency Wildfire Management Team formed and began holding bi-weekly meetings. The same year, land managers conducted a prescribed burn in the Western Perimeter. An Inter-Agency Fire Management Plan, developed around that period, outlined cooperative arrangements for communication and suppression among LAFD, Los Alamos County, LANL, the Forest Service, and the Park Service, and made recommendations for fuel mitigation.

The urgency behind those early efforts was quantified in modeling work by William Armstrong of the Santa Fe National Forest. His 1998 and 1999 analysis of fuels in the Sierra de los Valles predicted a 38% chance of a crown fire reaching the townsite or LANL structures within five years. Fire and land managers from LAFD, the Santa Fe National Forest, Bandelier National Monument, and LANL were already working the problem in the late 1990s, but Armstrong's figures gave the risk a precise, sobering dimension.

The mitigation projects that followed were specific and targeted. In 2007, LANL completed fuel reduction on about 15 acres in Los Alamos Canyon adjacent to Ridgeway Drive, including work on a critical parcel below Fairway Drive. Fuel reduction in DP Canyon began in 2009. From 2010 to 2013, firebreaks were constructed around much of the laboratory's perimeter. San Ildefonso Pueblo contributed its own fuel reduction projects along the New Mexico Highway 4 corridor and in canyon areas of middle Los Alamos County.

Los Alamos County joined the New Mexico Resource Mobilization Plan in 2016, adding another formal coordination layer for regional fire response.

On the monitoring side, LANL operates 68 air monitoring sites, a density the laboratory describes as making it "one of the most thoroughly monitored environments in the world." The lab also stores waste and materials away from potential wildfire paths and maintains evacuation processes and procedures should a fire advance. On the question many residents raise about the lab's nuclear mission, LANL states directly: "There is no more risk of radiation spread at the Laboratory than anywhere else in New Mexico."

LANL has also produced a library of public-facing videos on the subject, ranging from a 1:38 overview of fire mitigation efforts to a 2:53 explainer on radiation protection and a 2:28 segment titled "When Wildfire Meets Water: It's Complicated," which addresses the downstream water quality concerns familiar to anyone who lived through the aftermath of the Las Conchas fire.

The interagency architecture built since the mid-1990s now connects LANL, LAFD, the Santa Fe National Forest, Bandelier National Monument, San Ildefonso Pueblo, and county emergency managers in a shared framework that has grown substantially more sophisticated than the bi-weekly IWMT meetings that launched it thirty years ago.
