How to Minimize the Environmental Impact of Your Campfire

For many outdoors enthusiasts, the epitome of camping is sitting around some crackling flames. A campfire in the woods has primal, universal appeal and delivers both atmospheric and practical benefits, from basic warmth against the night chill to an old-school means of cooking and boiling water.

But campfires also have an environmental impact. Recreating lightly on the land should be a priority of all outdoorspeople, and that means taking whether and how to have a fire on your excursion under careful consideration. In this guide, we’ll discuss how to minimize campfire impacts while still enjoying the intrinsic pleasure of that friendly little glow!

Are Campfires Bad for the Environment?

Building and fueling campfires can have big consequences for the landscape. Constructed fire rings and their charred wood, scorched rocks, and (all too often) trash are unsightly and damaging to groundcover. So are commonly associated impacts, such as the beaten-down earth, hacked-at branches and tree trunks, and user paths that often mar a campfire spot’s near radius.

These are examples of “site creep,” where a campsite’s footprint expands beyond the main, heavily used center. Another campfire issue at popular backcountry campsites and camping areas is “firewood mining,” where backpackers’ heavy gathering of wood for campfires depletes the vicinity’s supply of downed logs, branches, and twigs—deadwood that provides both habitat and nutrients.

And then, of course, there’s the very real potential of a campfire getting out of control and sparking an honest-to-goodness wildfire. This may happen when backpackers light a fire during hazardous “fire weather” periods, such as exceptionally dry or windy conditions. It may simply result when you build a fire that’s too large to control or fail to have tools on hand to do so, such as water and a shovel. Often campfires turn into wildfires when campers fail to properly extinguish them and they’re left to smolder. A smoldering campfire may ignite vegetation days after it’s abandoned; it may also spread through duff and cause a root fire, a partly underground blaze that can be very difficult to put out.

Long story short, there are many ways a poorly sited or managed campfire can cause long-lasting ecological impacts—and detract from the experience of other hikers, backpackers, and hunters who might pass by the heavy evidence of your campsite.

Fortunately, there are steps you can absolutely take to lighten the environmental effects of a campfire—should you choose to have one in the first place.

Factors to Consider Before Building a Campfire

The easiest way to minimize campfire impacts? Well, going without a campfire, of course! Some backcountry users eschew campfires altogether to tread more lightly on the land. Many others, however, choose to build them occasionally with well-reasoned discretion. (Later in this article, by the way, we’ll talk about alternatives to campfires, so fear not.)

When deciding whether or not to have a fire, here are some important considerations:

• What is the current fire danger for the location you’re camping in? This often relates to the time of year: Late summer or early fall in much of the American West, for example, is the typical season for maximum fire danger, as much vegetation has “cured” and dry or even drought conditions are common. But unusual weather patterns may promote high fire danger even outside the “normal” window. There’s a locational element here, too: Some places, such as dense, brushy woods, are going to be inherently more fire-prone than others, such as sandy washes or beaches.
• Are there current fire bans or restrictions in place? In periods of high fire danger, land-management agencies often ban the use of campfires. Campfires may also be prohibited in especially sensitive areas, or (as in some national parks) outside of official, designated campsites. Always check with whatever agency or other authority is responsible for the area you’re camping in to see whether fires are allowed.
• Does the vicinity of your campsite have enough wood that gathering some won’t be noticeable or reduce a scarce, ecologically valuable resource? This may be a reason to eschew a fire in, say, a popular camping area showing signs of firewood mining, or in an ecological setting—say, above timberline or in an arid region—where dead and downed wood is naturally hard to come by.
• Is there an existing fire ring, or do you have the tools to create a low-impact campfire? We’ll get into this in the next section, but keep in mind that making a fire—especially a traditional, higher-impact campfire—in a “pristine” spot generally has a bigger impact than taking advantage of an in-place fire ring or using a fire pan.

6 Ways to Reduce the Environmental Impact of Your Campfire

Here are some ways to pull off a responsible and lighter-on-the-land campfire:

1. Use Mound Fires

A mound fire is one that’s built insulated from the ground and is easy to clean up with minimal evidence. It gives you the ability to have a fire on bare rock, gravel, sand, and other surfaces not conducive to a traditional fire but much less impacted than vegetated groundcover. (That said, you can build a mound cover over grass or duff if you don’t have another choice, and the method will better protect that vegetation.)

To make a mound fire, lay out a fire-resistant ground cloth and place several inches of mineral soil in a circular, level heap on top. Mineral soil is dirt, sand, grit, or gravel with little organic matter; you can often find it in or under the root wads of fallen trees or along exposed or dry riverbeds. Use a folding shovel or trowel and a stuff sack to gather and transport the mineral soil.

Make sure your cloth extends beyond the perimeter of your mound, and that your mound, in turn, is significantly broader than the size of the fire you build on top of it. This keeps coals and embers contained on the soil and makes for easy cleanup.

When your mound fire has burned down to white ash, douse it thoroughly until it’s cool enough to touch. Then disperse the cold ashes widely away from your campsite. Hoist the ground cloth with the mound and return the mineral soil to the area you harvested it from.

2. Use Existing Fire Rings

Where dispersed campsites with well-used fire rings already exist, favor these as another option for low-impact camping. Many backcountry areas include such dispersed sites that have been utilized by backpackers, hunters, climbers, and other users over many years. Building a fire in established fire rings concentrates campsite effects, reducing the overall human footprint on the landscape. Wildlife may also be less disturbed by this approach, as they may be accustomed to occasional human presence at habitually used dispersed campsites.

3. Source the Right Kind of Firewood

If you’re car camping (and therefore able to more easily transport firewood to your campsite), make sure you’re acquiring firewood locally. Moving firewood—whether commercially bought or harvested/split yourself—long-distances is a major source of spreading invasive insects, fungal disease, and other pests, which can have disastrous consequences for local flora and ecosystems.

Only gather dead and downed wood for your campfire. Don’t cut down or remove branches from standing dead trees; these snags provide critical habitat for a host of creatures. Favor small pieces of wood: no thicker than about the diameter of an adult wrist. Collect firewood at least 200 feet away from your camp and avoid excessively harvesting from one area. Fetch a little wood from one spot and move on to another.

Driftwood (as from an ocean or lake beach or a river bar) is an example of a more sustainable source of natural firewood (although, to be clear, it still provides habitat and resources for organisms).

4. Don’t Burn Trash

We hope this goes without saying, but, then again, it’s woefully common to see plastic containers, aluminum cans, and other garbage strewn in firepits—from developed campgrounds to the deep backcountry. Besides the basic unsightliness and visible litter, burning (or trying to burn) trash can emit or leach polluting vapors and chemicals into the environment. Follow the pack-it-in, pack-it-out policy when it comes to such inorganic waste (and, to be clear, consider packing out a lot of your organic waste as well!).

5. Campfire Dousing & Cleanup

Properly dousing your campfire and disposing of its residue not only help prevent wildfires but also erase as much as possible signs of your fire: another goal of low-impact campfire-making.

Allow fires to burn down to white ash, then douse them with plenty of water, sifting the ashes as you do so. Consider a fire out only when it’s cool to the touch and no longer smoking. When you’re leaving a campsite, spread the ashes 200 or more feet from your camp and across a broad area.

6. Alternatives to Campfires

A fire pan serves as a popular low-impact alternative to a traditional campfire or mound fire. These metal containers allow you to build a fire elevated off the ground with no-hassle cleanup. You can purchase specially made fire pans or jury-rig a metal oil pan or garbage-can lid for the purpose. Place the pan atop a scaffold or rocks or on mineral soil to prevent scorching of the ground, and put mineral soil in the fire pan for further insulation. Disperse cold-to-the-touch ashes from your fire pan in the manner we’ve already described, and be sure to return mineral soil or scaffolding rocks to their original location.

Camp stoves are the go-to alternative to a campfire for many backcountry users. Stoves are more efficient for cooking over, after all, and don’t come with the same extractive or visual impacts of a fire.

Other Fire Safety Tips

Always have a shovel and water ready to hand when enjoying a campfire. Favor smaller fires over big blazes, which not only increase the likelihood of alighting surrounding vegetation but also increase the visual impact of your campsite. Use water, not dirt, to douse your fire: Dirt can insulate live coals, and if it’s organic soil, it may itself be flammable.

Never leave a campfire unattended: Always have somebody monitoring and managing it. This takes some diligence during a lively social camping getaway: It’s all too easy for everybody to trundle off to a nearby vantage for sunset appreciation or crawl bleary-eyed to sleeping bags without actually actively dousing a dying-down fire.
