Windthrow Management Guidance

Windthrow Management Challenges

The new practices which are required or encouraged make windthrow management more challenging by:

  • requiring more within-block residual patches and individual trees
  • increasing the ratio of edge to harvested area with smaller blocks
  • requiring placement of treed reserves adjacent to riparian areas and gullies
  • limiting the use of natural timber types or topographic changes for boundaries.

To respond to this challenge, managers must:

  • be more observant and systematic in assessing windthrow risk
  • be realistic about the likely outcome of prescriptions
  • be more creative in designing prescriptions to reduce damage
  • recognize that some windthrow in reserves may be non-harmful or even beneficial, and to that end, include in prescription documents a statement of what level of windthrow may be acceptable.
