King County iMap - noxious weeds layer

Open King County iMap and add the Noxious Weeds layer. Zoom in to show the weed locations, click on legend button to see the species names, and open layer list to see data options. For help using this tool, visit the King County iMap page.

The data on noxious weeds represents locations where these species were located in current or previous years and may not represent what is present at the current time. Generally only regulated noxious weeds are mapped by the noxious weed program, but where data is available on non-regulated species that is also included. To find out which species are regulated and not regulated in King County, see the King County Noxious Weed List.

For more information about this map or the data, please contact the staff at the noxious weed program.
