Winter provides an opportunity to conduct harvest
operations in areas which might be sensitive during warmer drier times.
One example is wetland areas which are particularly suited to being logged
during winter. The snow pack can provide support across wet areas which
would be deeply rutted if logged
during the summer months. Freezing of some wetland areas can also extend
operating periods and reduce impact from logging. Operations conducted during
cold weather months have different maintenance requirements. Roads are vulnerable
to heavy damage and erosion if not maintained correctly. However, if properly
maintained during winter months, road usage can extend the logging
season without creating excessive impacts. Some of the issues of winter
operation are: |
|
| |
- Remove snow from roads initially to allow deep freezing which will
increase stability of the road base.
- After roads have frozen solidly, maintain packed snow on the road
to insulate the frozen road base.
- Berms of snow along road edges can keep melted snow on the road surface
from entering streams.
During times of alternative freezing and thawing, suspend operations
if deeply frozen road base begins to thaw.

Use a water bar to divert snow melt from frozen roads. |

Use snow berms to keep streams clean. |
