Careful Logging – Clearcuts

Regeneration, Residual Trees

Concerns Significance What are the Standards? How am I assessed? BMP’s

Careful Logging – Clearcuts

Regeneration, Residual Trees

Concerns Stem, branch and root damage – decay,

reduced growth, mortality Cutting/skidding-Destruction of

regeneration Skid trail coverage-reduced growth,

mortality

Careful Logging – Clearcuts

Regeneration, Residual Trees

Leads to growth loss, rot

Future volume and quality loss

Stem / Root Injuries

Careful Logging – Clearcuts

Long-term consequences: slow growth, rot

Regeneration, Residual Trees

Careful Logging – Clearcuts

Regeneration, Residual Trees

Root damage leading to:

Blowdown

And dieback

Careful Logging – Clearcuts

Standards: Meet the regeneration standards: Free to

grow, 40% stocking target to be considered a regenerated site

Maximize retention of advanced growth Soil/site protection will enhance natural

seeding Maximize leave strips

Regeneration, Residual Trees

Careful Logging – Clearcuts

Regeneration, residual trees

Maximize retention of established regeneration

This example: poor retention of established regeneration

Careful Logging – Clearcuts

Maximum regeneration retention

Careful Logging – Clearcuts

Standards:

Skid Trail Coverage Maximize leave strips

Regeneration, Residual Trees

Careful Logging – Clearcuts

Mortality is linked to the proximity of a stem to the skid trail

Careful Logging – Clearcuts

BMP’s: consider impacts / BMP’s at each stage

Planning Felling Skidding

Regeneration, Residual Trees

Careful Logging – Clearcuts

BMP’s: Planning conditions / concerns in AWS – be aware identify important features on maps, aerial

photos, and in the field walk the block - know boundaries, water

bodies, stream locations and AOC’s on site, flag new trail and landing locations

Careful Logging – Clearcuts

BMP’s: Planning Think about how you will close off the

operation when doneRoad decommissioning?Culvert removal?Water bars in areas of potential

erosion?

Regeneration, Residual Trees

Careful Logging – Clearcuts

BMP’s: Planning-skid trails can old trails be re-used / upgraded?

Relocate if trail: goes into an AOC unnecessarily poorly placed / unnecessary water

crossings poor drainage unstable soils, can’t be improved

Regeneration, Residual Trees

Careful Logging – Clearcuts

Regeneration, Residual Trees

BMP’s: Planning-Skid trails

Determine the skid trail pattern and mark a tentative layout before starting the job

Walk the block first, don’t plan trails from the back of the skidder
