Cattle won't eat false broomweed; it quickly pushes out native forage plants, and it resprouts readily despite chemicals, burning, and a variety of mechanical measures.

Other dominant forbs within quadrats at the grazed site were western ragweed (Ambrosia psilostachya), common broomweed
(Gutierrezia dracunculoides), and hog potato (Hoffmannseggia glauca).
Dominant forbs are broomweed
(Gutierrezia texana), hog potato (Hoffmannsegia glauca).

Amphiachyris dracunculoides (DC.) Nutt., Prairie broomweed
Response of false broomweed
and associated herbaceous species to fire.
The modern prairie vegetation is dominated by big bluestem (Andropogon gerardii), indiangrass (Sorghastrum nutans), switchgrass (Panicum virgatum) and little bluestem (Schizachyrium scoparium); subdominant species include tall dropseed (Sporobolus asper) and sedges (Carex spp.) along with western ragweed (Ambrosia psilostachya) and annual broomweed
(Gutierrezia dracunculoides) (cf.
Vegetation in this area consisted of mesquite (Prosopis glandulosa), creosote (Larrea tridentata), grama grass (Bouteloua sp.) and broomweed
The second locality was collected on 14 February 1991 (n=10; near Wichita Falls Clinic in Wichita Falls, Wichita County), and is about 40 kilometers northeast of the first site, where broomweed
(Amphiachyris dracunculoides) and dense stands of mesquite predominate.
We took a male (TTU 62373, testes 5 X 3 mm) at this same locality, on 27 August 1992, in mesquite grassland with abundant broomweed
and scattered Opuntia.
After waiting 25 minutes, I took up the trail through the waist-high grass and broomweeds
. Even though I felt good about the shot, I found only a few spots of blood and decided to back out to get some help with the trail.
As a result of suppression of fires and overgrazing, it now is dominated by woody plants such as honey mesquites (Prosopis glandulosa) and chollas (Cylindropuntia), forbs such as prickly pears (Opuntia phaeacantha), common broomweeds
(Xanthocephalum dracunculoides), and small soapweed yuccas (Yucca glauca), but also includes grasses such as blue grama (Bouteloua gracilis), sideoats grama (B.
