Weed Watch!

Colorado Weed Management Association

1st Quarter Newsletter 2023

February, the end of winter is in sight, or is it? Some of us may be eager to get our spring weed control started and others may still be clinging to their skis, praying for snow well into April.


Either way, your CWMA Board of Directors are hard at work to bring you the 2023 Spring Training and increase the value CWMA brings to its membership.


We enjoyed seeing you all at the Winter Training and thank you for your support.

Northern Colorado Big Game Critical Winter Range Restoration Project


by Alex Wendorf, Larimer County Parks and Open Lands Weed Specialist

A new cooperative of land managers has been awarded a grant from the National Fish and Wildlife Foundation for the Northern Colorado Big Game Critical Winter Range Restoration Project. This project aims at long-term control of invasive winter annual grasses by treating 4,385-acres of cheatgrass and feral rye across seven open space properties managed by Larimer County Natural Resources, Colorado Parks and Wildlife, the City of Fort Collins Natural Areas, Boulder County Parks and Open Space, and Jefferson County Open Space.


The open spaces include Cherokee State Wildlife Area, Eagles Nest, Coyote Ridge Natural Area, Devil’s Backbone, Bobcat Ridge Natural Area, Hall Ranch, and Matthews/Winters Park. As a result of this project, vegetation communities on these lands will become more resistant and resilient to future disturbances, such as wildfire and drought, and provide critical habitat for native plants and wildlife. The properties are in critical elk and mule deer winter range and concentration areas. The restoration of cheatgrass and feral rye-infested habitat is by far the best way to improve overall native plant diversity and cover, that in turn provides critical habitat for big game, as well as small mammals, reptiles, birds and pollinators.


It is also worth highlighting that the mountain mahogany plant communities at these properties are extremely rare globally and found only in the northern part of the Colorado Front Range, southern Wyoming, and northern New Mexico.


An aerial herbicide application from helicopter will be utilized to adapt to varying terrain limitations, provide application uniformity, applicator safety and efficiency. In addition to herbicide applications, the project includes vegetation monitoring through transects in treated and non-treated areas, photopoints of treated areas to document habitat changes, and the use of a GIS tool, RangeView, to determine cheatgrass densities in treatment areas. 


At the 2022 Colorado Weed Management Association Winter Training, project partners were honored to receive the CWMA Partnership Award for the Northern Colorado Big Game Critical Winter Range Restoration Project. The Partnership Award recognizes local groups or organizations that have advanced the objectives of weed management through technique, team efforts, and communication or education efforts.

Weed Awareness Campaign

February Weed of the Month: Cypress Spurge (Euphorbia cyparissias)

prepared by Alicia Doran, Jefferson County Invasive Species Management Coordinator and Pest Inspector

Cypress spurge is a List A perennial that is an escaped ornamental. Originally from Eurasia, it was first reported in the US in 1858 and in Colorado in 1895. It is not very common in Colorado but can be found in landscaped areas and has been found escaping into natural areas.


The plants usually grow to less than 16 inches tall but may reach up to 26 inches tall. It forms dense patches of multiple slender stemmed plants. The stems may branch in the upper half of the plant. Leaves are narrow, less than 1/8 inch wide and about 1 inch long. Flowers are reduced and have a pair of yellowish-green bracts beneath. Flowers occur in spring through early fall and become reddish later in the season. Roots can be 15 feet deep and woody rhizomes spread horizontally up to 35 feet. 


There are both seed and non-seed producing populations. The seeded varieties form seed pods that contain one to three seeds. The sticky seeds explode when the pods ripen. The seed producing varieties will sometimes hybridize with Leafy spurge (Euphorbia virgata formerly known as Euphorbia esula). The genetics of Cypress spurge are complicated including both diploid and tetraploid types.


The plants contain toxic latex that is irritating to skin and eyes and causes rashes and blisters on lips and skin. Most native animals and livestock do not feed on it.

Native Plant Spotlight: Creeping Mahonia, Mahonia repens

By Ethan Proud, Archuleta County Weed and Pest Supervisor

Creeping mahonia, goes by many names...most including the word creeping. Its list of common names include: creeping Oregon grape, creeping barberry, and prostrate barberry. Its growth habit is a subshrub, and it grows low to the ground and spreads through stolons. It's bright yellow flowers appear in the middle of spring, and give rise to blue berries later in the year. In the fall the leaves turn bronze to maroon. It forms an attractive ground cover in native ecosystems and gardens.


The berries are edible but edible and can be used to make jelly or wine.
