How to get listed on the map

Parks, arboretums, gardens and other outdoor areas in King County may participate.

  1. Grounds keepers or landscape managers review the definitions below.
  2. They decide if their pesticide practices allow them to be listed as Pesticide‐Free or Pesticide‐Reduced.
  3. Contact Julia Singer 206‐263‐1670 to be listed or with questions.


Pesticide‐Free Site

No EPA‐registered pesticides are used in the normal maintenance of the park or recreation area. Special exemptions are given for limited IPM based use of an herbicide to remove a noxious weed where this is the only feasible recommended method according to King County Best Management Practices, or in the case of an insecticide used to remove dangerous insects (wasps, hornets) as long as adequate notification or signage is used to warn the public.

Pesticide‐Reduced Site

Children’s play areas and lawns are pesticide‐free. In outlying areas of the site: flower beds, fence lines, natural areas and playing fields, grounds managers use their own IPM policy to determine pest control needs and minimize use of pesticides.

The Environmental Protection Agency says that a pesticide is any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest.

Special problems

Noxious weeds are non-native plants that grow rapidly and overwhelm natural and agricultural areas. They can clog waterways, destroy native habitat, or lessen crop yields and value. Some are poisonous to humans or livestock.

Washington state law requires public and private landowners to control certain noxious weeds that are not yet widespread and where there is still a chance to prevent them from spreading to the rest of the state. Managing noxious weeds effectively and safely may in some situations require careful use of pesticides. Read a Citizens Guide to Noxious Weeds (PDF) for a general overview, or visit King County’s Noxious Weeds.

For questions about natural areas and weed control, or to report a noxious weed site, contact the King County Noxious Weed Control Program, 206‐296‐0290.
