#130: Burning Questions: Understanding Fire Management with Lenya Quinn-Davidson

#129: Wide-Angle Listening: How Nature’s Soundtrack Completes Your Connection to the Wild  Nature's Archive

Summary

It’s summertime, and around the globe record heat is dominating, from Europe to the midwest, and across the oceans as well.

As you know, heat is a key driver to wildfires. In fact, it is one of the three key ingredients, along with fuel and oxygen.

Global oxygen levels, at least within our lifetimes, aren’t going to change much. But heat and fuel can and will change. Obviously, heat is increasing, so one variable is driving more fire potential. And in many areas, fuel is also increasing. Whether it be from invasive species like cheat grass in the high deserts, or excessive understory growth due to both invasive species and decades of fire suppression.

Sometimes fuel is indirectly created by heat, which causes die-off of many trees and shrubs. And more complex still is the die-off caused by pine beetles, which are actually native. But they can turn destructive when excessive heat weakens tree defenses, and due to the forest service treating so many forests as dense monoculture crops.

I’d like to share this interview with Lenya Quinn-Davidson, discussing fire management. This interview was recorded 2 years ago, but is more relevant than ever. 

Case in point, we’re barely into the traditional fire season and 2026 has already had record breaking wildfires in Nebraska, and Oklahoma and Kansas had a nearly 300,000 acre wildfire in February, along with a 35000 acre fire in Florida.

Wildfire is complex, often misunderstood, and turned into political fodder. So please take a few minutes and enjoy this episode from the archive.

Original Intro:
Many of you might recall the dramatic 2020 fire season in the western USA. In California alone, close to 4 million acres burned. Cities were clouded with smoke and unhealthy air for many weeks. I had ash fall at my home in San Jose, CA on several occasions.

But did you know that based on pre-colonial historical estimates, 4 million acres burned would be considered “below average”. How can that be? Does that mean that every summer in the 1700’s had smoke filled air and devastating fires? Spoiler alert: the answer is no.

In today’s episode, we reconcile how it was possible for more acres of land to burn every year, but with less dramatic impact. In fact, that historical fire was largely beneficial to the land.

Our guest today, who helps us decipher historical fire and how we can add more beneficial fire back to the landscape is Lenya Quinn-Davidson.

And when you have a guest who’s first name literally means “firewood” in Spanish (alternative spelling), you know you’ve found the right person to discuss wildfire management. 

But Lenya Quinn-Davidson’s qualifications extend well beyond her name. She’s the Director of the FIRE network for the University of California’s Agriculture and Natural Resources organization. She focuses on the various ways humans connect with fire, including the use of prescribed fire for habitat restoration, invasive species control, and ecosystem and community resiliency. She’s actively engaged in local and national prescribed fire communities, and is an advocate for increasing diversity in the world of wildfire. 

A quick aside before we get into the interview. Obviously, climate change is a huge component for why we see bigger fires. Heat has a disproportionate impact on fire intensity. So while we don’t talk about climate change much today, it is absolutely an amplifying factor in wildfire intensity and frequency.
