Noxious Weeds

Four very successful weed events were hosted in 2018 with over 579 participants, 458 vehicles, and 1,726 bags of weeds collected. The Town of Estes Park Parks Division handles the noxious weed control on Town property. In addition, the Town teams up with the Estes Land Stewardship Association (ELSA) to hold the traditional Weed Roundup and two or more Monitored Weed Drop-offs each year. These events are made possible with the support from ELSA, the Town of Estes Park, Larimer County Natural Resources, Estes Valley Land Trust, Colorado Department of Agriculture and local donors.

ELSA meets the first Thursday of the month (January thru November) at 9:30 a.m. in the George Hix Room at US Bank.
