- It's not possible.

On the one hand, it is everywhere where there are wetlands, but it also plays an important role in the ecosystem, says Kerstin Isaksson.

She lists a number of fungi and plants that are poisonous and explains that it is impossible for the municipality to remove everything in nature that is dangerous.

- The only way is to teach children not to eat something they do not recognize.

Because the explosive herb likes nutrient-rich water, it spreads more easily in lakes that are eutrophicated.

Isaksson believes that humans can therefore affect the spread of explosives in the future.

- It may happen that the explosive herb has increased in recent years, but then it is due to the fact that we have released more nutrients into the water.

In addition to the shoreline on Hamre, the explosive herb grows along the Black River, on Björnön and on Ängsö.
