Noxious Weeds

Update 09.26.17

Three very successful weed events were hosted in 2017 - July 22nd Weed Roundup, and the August 26th and September 23rd Monitored Weed Drop-offs - with over 636 participants, 499 vehicles, and 2,329 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 a Weed Round Up and one or two monitored weed drop offs annually. These events are made possible with the support from the Estes Land Stewardship Association (ELSA), the Town of Estes Park, Colorado Department of Agriculture, Estes Valley Land Trust, Larimer County and individual 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. For more information about ELSA contact

The Town-sponsored free weed drop-off site has closed due to funding constraints and public misuse by dumping trash and other materials. Residents may dispose of noxious weeds at the monitored free weed events or pay a standard disposal fee at the Estes Park Transfer Station. Unauthorized/illegal dumping at this location is considered theft of services.

*  The Town of Estes Park is currently participating in a study to control the invasive weed known as "cheat grass," Cheat grass is a rapidly growing problem in the Estes Valley, overtaking native plants, compromising wildlife habitat and increasing fire danger. The study will occur 2016-2018 as a partnership among Colorado State University, Larimer County and the Town of Estes Park's Parks Division. Study areas are marked with small flags and located on Town-owned parcels at Highway 7 & Community Drive, Elm Road off Highway 36, as well as off of Fish Hatchery Road. Informational signs have been posted. The study evaluates the effectiveness of a product used to control cheat grass at high elevations.
