For many people, a large bonfire on August 1st is an integral part of the national holiday. However, what is hardly known is that the piles of wood, often stacked days or even weeks in advance, are frequently used as shelter by hedgehogs, toads, slow worms, mice, and other wild animals. If these woodpiles are lit without supervision, it often ends in agonizing death for the animals.
Every year, countless wild animals die in the flames of August 1st bonfires – animal suffering that can be prevented with simple measures.
The Susy Utzinger Foundation for Animal Welfare (SUST) calls on organizers of bonfires and the general public to take consideration for wild animals when building and burning woodpiles.
Here's how to make the August 1st bonfire more animal-friendly:
Hedgehogs are crepuscular and nocturnal. During the day, they seek sheltered hiding places in piles of branches and leaves, where they feel safe. Female hedgehogs, in particular, are often looking for a suitable place to give birth to their young in the summer. A stacked woodpile offers ideal conditions for this. Since hedgehogs curl up into a ball when threatened instead of fleeing, they have little chance of escaping when a fire is lit. The same applies to baby hedgehogs, which are completely defenseless in their first few days. They are born blind and deaf and would die a miserable death in a fire.
This avoidable animal suffering can be prevented with just a few simple steps.
“An August 1st bonfire should bring joy to people – not cost wild animals their lives,” says Susy Utzinger, Managing Director of SUST. “Anyone who only piles up a woodpile on the day of the burning or carefully rearranges it beforehand can prevent a lot of animal suffering with little effort.”
