Forest Cycles

Westside Puzzle

The forest in this example is managed to grow trees quickly.

This is one of the many ways to manage a Douglas-fir forest west of the Cascade Range to produce timber for wood products. Patches of trees in these managed forests are usually kept even-aged, which means all the trees are the same age.

Managers may choose the following activities to achieve their goals:

  • Thinning (cutting some trees) makes more water, nutrients and sunlight available for the remaining trees.
  • Pruning produces wood without knots.
  • Fertilizing encourages faster growth.
  • Prescribed fires, set purposely by forest managers before planting trees, reduce fuel or dead wood and competing vegetation.
