Four-Legged Firefighters

In Spain, donkeys are helping to keep wildfires from spreading, just by eating.

The Tivissa Donkeys Firefighters are used to clear vegetation in Spain. The donkey in this photo is part of another program called “Rucs al bosc,” or “Donkeys in the Forest.”

Wildfires can cause a massive amount of destruction. But in Spain, a group of four-legged firefighters are helping to keep the blazes under control.

An organization called Tivissa Donkeys Firefighters has been putting rescued donkeys to work since 2020. More than 30 of Tivissa’s donkeys eat dry grass in the Catalonia region of Spain, keeping it from getting overgrown. The donkeys also break up this vegetation just by walking on it, so wildfires don’t have a clear path. As a result, fires have less fuel and spread less easily.

It’s a job that could also be done by goats and sheep, which are herbivores (plant-eaters) like donkeys. But Joan Cedó Sans, who founded Tivissa, says donkeys are the most effective firefighters. 

“The work donkeys do, neither goats nor sheep can do,” Cedó told CNN. “[Donkeys] weigh more, so every time they tread [step on the ground], they tread harder, they eat more.” 

Tivissa isn’t just a firefighting organization. It’s also an animal rescue, taking in donkeys that have been mistreated in some way. Now the animals lead a peaceful life, doing what they would naturally do while unknowingly helping to prevent disasters.

Donkeys from the “Rucs al bosc” program happily do their jobs.

The donkeys’ work is especially important right now. Many parts of Europe, including Spain, have been battling wildfires all through the hot, dry summer of 2026. Climate change has made the continent hotter and drier, so wildfires are more likely to break out and spread. The donkeys alone are not going to solve the problem, but they can help.

“It is difficult to guarantee that with livestock grazing there will be no fires,” Jordi Bartolomé Filella, a university professor who studies herbivores, told CNN. “But it can make them lower in intensity, and therefore easier to extinguish.” 

The donkeys are always willing to do their part.

Wildfires 101

You may have heard about wildfires in Europe, Australia, and North America. Wildfires are becoming more common. But why, and what can be done about it?

How Do Wildfires Start?

Wildfires are part of nature. They’re an important part of keeping forests healthy because they clear out old leaves and other vegetation and make way for new growth. Some wildfires have a natural cause, like when a bolt of lightning hits a tree. 

But most wildfires are started by people. For example, someone might leave a campfire without putting it out, or an engine that needs repair might produce sparks.

Firefighting aircraft can drop water or chemicals over a wildfire to help put it out.

Why Are Wildfires Becoming More Common?

Wildfires need fuel, heat, and oxygen to start and spread. You may know that it’s easier to start a fire if the fuel is dry. Hot, dry weather can dry out a forest, making it easier for fire to spread, using dry leaves and logs as fuel. Wind can spread the flames farther.

Climate change is making the world hotter and causing droughts (long periods of dry conditions) to happen more often. It’s a perfect recipe for wildfires.

Campers can reduce wildfire risk by building fires away from leaves and plants.

How Can We Prevent Wildfires?

Here are a few tips!

  • Keep dry leaves and plants under control so that fires have less fuel. If you read today’s top story, you know about a herd of donkeys that is doing this in Spain.
  • Build campfires in areas that are not close to dry leaves and plants. Make sure campfires are put out completely before leaving a campsite.
  • Don’t start outdoor fires near buildings, especially when there has been a drought.
  • Keep cars and other machines in good repair to make sure they don’t make sparks that can start fires.
  • Help slow the effects of climate change by recycling, turning off lights, using less water, and unplugging chargers when they’re not being used.
