Noxious Weeds

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 Weed-Round Ups. For 2017 there are three Weed Roundups scheduled for July, August and September.

The Estes Park Week Roundup is the Estes Valley's "Noxious Weed University" where participants will receive expert assistance identifying unknown, weedy plants, learn how to rid their yards of pesky weeds, and take home educational materials about invasive plants. This year the Estes Land Stewardship Association (ELSA), Larimer County and the Town of Estes Park will hold three separate Weed Roundup events. The events take place July 22, August 26 and September 23 from 9 a.m. to 12 p.m. at 666 Elm Road. Pulled weeds must be in large paper lawn bags, available at local hardware and lawn and garden stores. Plastic bags and non-weed materials cannot be accepted.

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 three free Weed Roundups or pay a standard disposal fee at the Estes Park Transfer Station.

*  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.
