Vegetative Manipulation 

Another effective method of reducing the visual impact from a proposed activity or development is to retain as much of the existing vegetation as possible, and where practical, to use the existing vegetation to screen the development from public viewing areas.

Some other techniques include:

  • Designing vegetative openings to repeat natural openings in the landscape. Edges that are scalloped and irregular are more natural-looking. Straight line edges should be avoided.
  • Minimizing the impact on existing vegetation by:
    • Partial clearing of the limits of construction rather than clearing the entire area – leaving islands of vegetation results in a more natural look.
    • Using irregular clearing shapes.
    • Feathering/thinning the edges of the cleared areas. Feathering edges reduces strong lines of contrast. To create a more natural look along an edge, a good mix of tree/shrub species and sizes should be retained.
    • Disposing of all “slash.”

Following are some examples of proper vegetative manipulation.

The edges of this vegetation clearing have been thinned or “feathered” to create a natural-looking treatment.

The use of irregular shapes with “feathered” edges during vegetative clearing yields a more natural looking environment.
