Culvert blockage
- Infrastructure deterioration;
- Ineffective drainage causing subsidence or flooding;
- Damage to riparian properties.
Road deterioration
- Collapse of an upstream beaver dam releasing a large amount of water;
- Roadbed deformation and water infiltration through the embankment.
Structural destabilization
- Unstable ground, weakened retaining walls;
- Affects the stability of building structures and infrastructure.
Subsidence of railroad embankments
- Water infiltration causing frost heave through capillary action;
- Deterioration of structural components;
- Ballast contamination;
- High maintenance costs (derailment).
Spring ice jams
- Flooding of residential or agricultural areas and roads;
- Accumulation of beaver dam debris in the infrastructure.
Loss of forestry and agricultural production<
- Flooded logging areas;
- Reduced tree growth;
- Damage to new plantations;
- Major loss of fertile land.
Drinking water contamination
- Flooded logging areas;
- Reduced tree growth;
- Damage to new plantations;
- Major loss of fertile land.
Road structure subsidence
- Culverts, bridges and ditches blocked by beavers cause road subsidence;
- Risk of accidents, material loss, injuries and death.
