The strip selection system manages age classes in regular strips rather than unspecified group shapes. This system was developed to provide advantages for managing windthrow. As with other systems using strips, the strips should be oriented perpendicular to the prevailing wind. If cutting proceeds systematically against the wind, the stand develops an aerodynamic shape, with further advantages for wind protection (see diagram).
Again, this system differs from the strip shelterwood system in that the strips are removed over three or more passes to give a truly uneven-aged stand and their removal occurs much more slowly. The cutting period between passes will be 15-30 years, depending on the number of passes, and a regular rotation is needed to complete all passes.
As in the strip shelterwood system, the strip width in the strip selection is sufficiently narrow to create an environment that differs substantially from a clearcut and produces strips that are too small to qualify as individual stand units. Because they have the advantage of one long dimension, strips tend to be narrower than groups. Where mature timber heights are 30-35 m, strips widths of 15-50 m will be used, depending on orientation and objectives. These systems are well suited to small skyline systems.
What mighty battles have I seen and heard waged between the trees and the west wind - an Iliad fought in the field of air.
