Rehabilitating Degraded Features and Sites
The following section summarizes the recommended best management
practices for rehabilitating degraded features
and sites on karst terrain. Be sure to check out more detailed
information in the Karst
Management Handbook for British Columbia.
Best Management Practices for All Vulnerability
The following best management practices are recommended:
- Evaluate degraded features or sites individually to determine
if rehabilitation efforts would be successful or lead to more
disturbance. Where more damage could result from rehabilitation
efforts, avoid undertaking any action.
- Rehabilitation efforts may include:
- stabilizing sinkhole sideslopes with grass seeding
- modifying tree planting where soil has been lost into epikarst cavities
- removing logging debris or windthrow from
sinking streams, surface karst features and cave entrances.
- Use low ground-pressure equipment and rubber mats for
recovering debris in or near sinkholes with unstable
rims and sideslopes.
- Keep the wheels or tracks of equipment at least 5 metres from
the edge of karst features. If not possible, keep wheels or tracks
parallel to the edge of features.
