Northwest Colorado officials tackle growing noxious weed infestation on Yampa River

Lauren Blair

A coalition of ranchers and environmentalists, politicians and bureaucrats, and Jimmy-Buffett-loving river recreationalists came together Friday to learn about a quiet scourge overtaking the banks of the Yampa River known as the leafy spurge.

The plant itself looks innocent enough, with little yellow flowers that turn entire sections of river bank into a sea of green and yellow. But the demure-looking weed is extremely aggressive and invasive, and has wreaked havoc in states like Montana and North Dakota, where more than 2 million acres of ranch land have been put out of production due to the noxious weed.

Formed in 2015, the Yampa River Leafy Spurge Project brought together partners in Routt and Moffat counties to tackle the growing infestation, which first took root more than 40 years ago.

"The reason we're concerned about it is the riparian area is spreading the seeds from here to Dinosaur National Monument," said John Husband, Northwest Colorado Chapter of Parrotheads and Leafy Spurge Project member. "What's difficult in riparian areas is how do we kill it without killing trees and other vegetation."

The problem has eluded an effective solution for decades, as the conditions unique to river banks challenge all variety of treatments from chemical to biological to mechanical.

The result is that debate continues about how to deal with the destructive plant, and for now, officials have focused on keeping the infestation from spreading.

"The goal might not be eradication but the goal is control," said Routt County Commissioner Tim Corrigan, who attended Friday's float down the Yampa to update and educate stakeholders on efforts to combat the weed. "The goal is to stop the bleeding."

Moffat County has taken a similar approach. Without better funding or better solutions, local officials have little recourse to completely eradicate the problem.

"We prioritize containment," said Moffat County Weed and Pest Manager Jessica Counts. "We want to keep the infestation where it is… and suppress and eradicate the weed outside the containment boundary."

The project received $30,000 in funding from the Colorado Department of Agriculture in 2016; Moffat and Routt counties each received $10,000 to fund projects to target infestations, and $10,000 went to landowner education and outreach.

Additional county and federal funds also flow towards containment efforts on private, county and federal lands, but for a weed that sends roots as deep as 60 feet down and is able to broadcast its seeds up to 30 feet, as well as send them downriver, available resources have been outmatched.

"For our economy's sake, from a recreational standpoint, an agricultural standpoint and an environmental standpoint, it's a big issue," said Todd Hagenbuch with Natural Resources Conservation Services.
