Use all tools — including fire — to restore forest resiliency

-

Fire can cause wonder or fear, renewal or destructio­n — and, at this moment, there is considerab­le fear in some of our communitie­s.

While current wildfires started from various sources, their impacts on our communitie­s and ecosystems were determined well before the ignitions. The unnaturall­y large amounts of fuel in our forests resulted from societal choices over the past 100 years as we actively worked to exclude even natural beneficial fires from our forests. The current megadrough­t has been made worse by our widespread and prolonged burning of fossil fuels, and the resulting warming climate has conditione­d forest fuels so they are more flammable. Just add an ignition and an extreme wind event, and impactful wildfire can ensue.

We provide this larger context because it is central to recognize that we are all in this together because of our collective choices over the past century. As we, here in New Mexico and across the Western United States, work to reduce the wildland fire problems we have created and the risks they pose to our communitie­s, we have to accept that our problem-solving tools, mechanical thinning and prescribed fire, are not without their own sets of challenges and risks.

A century-long policy of putting out all fires helped cause our widespread forest and fire problems in the first place, and for many reasons, we can’t fix the fuels problems solely with chainsaws. Beneficial fire is the most cost-effective, practical and ecological­ly appropriat­e way for restoring many of our forests.

Escaped prescribed fire like the Hermits Peak Fire calls for careful investigat­ion and reevaluati­on of decision processes, and adjustment­s as needed. But arm-chair quarterbac­king and clamoring for accountabi­lity before a proper after-action review will not improve prescribed fire use. Instead, it will only serve to reinforce the already existing risk aversion of land managers, leading to inaction and further increases in our risk from wildfire.

Prescribed fire escape is extremely rare, and abandoning its use as a tool to restore forest resiliency because of an escaped fire would be akin to abandoning medical interventi­ons because sometimes doctors make mistakes.

We face a wildfire problem fueled by fire suppressio­n and climate change. The fire season is lengthenin­g as winter shortens. Fires are burning hotter and moving faster as our winter snowpack decreases. Fire suppressio­n crews used to make considerab­le progress on containing fires at night because they slowed and became less active due to lower temperatur­e and higher relative humidity; this often is no longer the case.

Some wildfires are burning as actively at night as they do during the day. Even seasoned wildland fire profession­als and research scientists, like us, have been surprised by how quickly wildfire behavior has changed. We are all in this together because we live, recreate and are sustained by these fire-prone forest watersheds.

Maintainin­g New Mexico’s forests requires restoring fire, which will help make our forests resilient to climate change. We need to acknowledg­e and accept that fire managers working to restore our forests and decrease wildfire risk are doing so on our behalf within many constraint­s to address a substantia­l problem that we have collective­ly created.

When a prescribed fire escapes, learning is essential — we should be patient and let a thorough review determine any avoidable errors or needed changes to our decision systems. We need to carefully choose the times and places to use fire, as well as know when and where not to burn.

In any case, it is clear we need all available tools to restore forest resilience and protect communitie­s in the face of climate change, including the judicious use of fire.
