From the Field #2: what is fire ecology and why does it matter?
ok so. let’s talk about fire. not as a disaster, but as a natural, ancient, necessary process.
fire ecology is the study of how fire interacts with ecosystems. not just how things burn, but how fire shapes the land, how species respond to it, and how entire systems rely on it. it’s part of the cycle of life. dramatic, chaotic, and weirdly healing.
you’ll hear people say things like “the forest needs to burn,” and they’re not being edgy. some trees like lodgepole pine and knobcone pine literally need heat to open their cones. some grasses grow back stronger after a burn. fire recycles nutrients, clears out dead biomass, and reduces competition. it can help control pests and disease. it opens up space and light. and in many ecosystems—especially rangelands, chaparral, and savannas—fire is just part of how things work.
but here’s the problem. we’ve spent over a century trying to keep fire off the landscape.
colonization erased Indigenous fire stewardship—practices that worked with fire instead of fearing it. then came decades of aggressive suppression (thanks, smokey the bear) and more and more development pushing into wild spaces. now, mix in hotter temps, drier vegetation, and longer fire seasons because of climate change, and yeah. things aren’t looking great.
we’re seeing more extreme wildfires because we’ve created the perfect conditions for them. overloaded fuels, flammable invasives like cheatgrass and buffelgrass, drought-stressed plants, and a general disconnect between people and land.
this is where fire ecology comes in.
it helps us understand how fire behaves, how ecosystems respond, and how to restore balance. it supports the use of prescribed burns, fire-adapted planning, and listening to the Indigenous knowledge that’s been ignored for too long. it lets us ask better questions about what resilience actually looks like.
it also helps us shift the mindset. fire isn’t always bad. it’s not something we can just get rid of. it’s part of the system. and pretending we can live without it hasn’t worked out well for anyone.
if fire is as old as the land itself, and it built the ecosystems we depend on, what does it say that we treat it like a mistake?
