1. Why are they considered harmful?

Flooding of Land and Forests

Beavers build dams on rivers and streams.

Sometimes the water rises so high that it floods fields, gardens, or roads.

Tree Damage

Beavers gnaw on trees, especially poplars, aspens, and willows.

This can be a problem for forestry.

Infrastructure Problems

Beaver dams can flood roads, bridges, and canals.

Because of this, farmers, foresters, and some municipalities consider them pests.

2. Why do beavers believe that

They create ecosystems

Dams create ponds that become home to fish, frogs, birds, and plants.

This ensures biodiversity.

They regulate water flow

Ponds and wetlands are left dry after rainfall, reducing the risk of flooding downstream.

They maintain groundwater levels.

They purify water

Ponds also store organic matter, purifying the water accordingly.

They protect forests

Beavers gnaw on trees, but this stimulates new growth.

Some trees reproduce better thanks to beavers.

3. The Golden Mean

Beavers are neither enemies nor friends of humans. Everything depends on balance:

If beavers live in the wild, far from settlements and fields, the benefits are great.

If dams are built on fields, roads, or close to homes, conflicts are inevitable.

Today, many countries are teaching how to manage beaver populations rather than exterminate them:

Use special "water control devices" on dams;

Relocate beavers to less problematic areas;

Fence off logging sites near populated areas.

4. Conclusion

Beavers are true natural engineers. They contribute to the preservation of biodiversity, water purification, and river regulation.
However, they can be pests for humans when their actions disrupt livelihoods and infrastructure.

Conclusion: beavers are both helpers and potential "pests," depending on one's perspective and their habitat.
