Halogeton is a List C noxious weed species, meaning that it is widespread in Colorado and the goal is to suppress its populations. It is common in Arboles as it thrives in arid and semi-arid areas. It is a member of the goosefoot family and has small green flowers that are not noticeable. 

The seeds, however, are striking and have papery wings that catch the eye. Halogeton has red stems and fleshy, tube-like leaves. This plant can grow up to a foot and a half tall, but its taproot can extend just as far into the soil.

Halogeton is a problem in pasture and rangeland as it accumulates salt and is toxic to livestock. Dead plant material leaches the salt into the topsoil, which favors halogeton seed germination over that of native species. Halogeton is not typically selected by livestock as forage, which can lead to an increased population in heavily grazed situations. This is due to desirable forage being removed as a competitor while the halogeton is left to flourish. 

The seeds of halogeton do not survive long in the soil, but they can germinate one hour after exposure to water.

Master Food
Safety Advisors 

Do you have a passion for food safety and preservation? Then the Master Food Safety Advisors (MFSA) training is for you. MFSAs receive 30 hours of hands-on, research-tested food safety and preservation instruction. After completing the training and passing a written exam, MFSA volunteers give back 30 hours of service helping others practice safe food handling and preserve food successfully at home. Volunteers conduct demonstrations and assist with workshops, test pressure canner gauges, staff exhibits at county fairs and farmers markets, write articles, and answer phone calls and emails.
