Off With Their Heads! Broomfield Open Space Action Network Event Weed Pull Event
2026-06-13 08:00 - 10:00 | North lot of Paul Derda Recreation Center, 13201 Lowell Blvd, Broomfield, Colorado
Open spaces are full of life unique to Colorado and in order for that life to thrive, we need to remove troublemakers. Noxious weeds are plants that don’t play nice with other plants by pushing the desirable native plants out of the landscape. This reduces diversity in the spaces that noxious weeds occupy. Noxious weeds produce hundreds of seeds that could last up to 100 years in the soil! Broomfield Commons Open Space has noxious weeds that must be escorted out to let the natives move in.
We invite you to join us in the battle against Musk Thistle and Common Mullein along the northern- most border of Broomfield Commons Open Space.
This event is FREE and open to all ages, but bear in mind this is hard work.
We will meet in the North lot of Paul Derda Recreation Center (13201 Lowell Blvd). Broomfield City and County staff will be there, along with Colibri Creative Conservation Solutions, Broomfield Open Space Foundation, Butterfly Pavilion RMVs, and other open space champions from the community.
Wear long sleeves, long pants, closed-toe shoes, sun hats, and sunscreen. Bring gloves, snacks, water, and feel free to bring loppers, hand clippers, and shovels. We will provide some tools and trash bags as well.
Your sweat equity will pay off leaving a positive mark on Broomfield Commons Open Space!
