Integrated Pest Management

The City of Colorado Springs Parks Department follows an Integrated Pest Management (IPM) strategy that focuses on using a multi-faceted approach to better defend against pests. The objective is to control weeds in the City parks, open spaces, and public right of ways and insects that can be damaging to the urban tree canopy. The best weed control is a healthy, vigorously growing stand of turf grass that can out compete weeds.  We accomplish this by focusing on cultural practices such as mowing, fertilizing, irrigating, soil aeration/dethatching, topdressing, and overseeding.  Herbicides are then used, if needed, as a last line of defense.

The principles of our IPM procedures are as follows:

  1. Prevention- This is the most effective pest management strategy. By reducing the capacity of the ecosystem to support the target weed or pest populations through design and appropriate management, the opportunities for weed and pest establishment can be reduced or eliminated.
  2. Cultural- Cultural control is the use of management activities that prevent weeds and pests from developing due to enhancement of desired conditions.
  3. Mechanical - Mechanical control is accomplished by using physical methods or mechanical equipment to control weeds and pests. Mowing and hand pulling of weeds can be very effective.
  4. Biological - Biological controls include the introduction or enhancements of natural enemy populations to target weeds or pests.
  5. Chemical - When chemical control of weeds or pests is necessary General Use herbicides are applied. No Restricted Use pesticides will be used in park landscapes.

The majority of the herbicide applications that take place in our park system are performed by outside contractors.  All applicators are commercially certified and licensed through the Colorado Department of Agriculture and only apply products that are registered through the Environmental Protection Agency (EPA). Prior to the application being made the applicator will place yellow flags at conspicuous points of entry into the area indicating that an herbicide has been applied. When the herbicide is applied the applicators make spot treatments and only apply to areas containing target weeds. The area is safe to reenter once the product has dried.
