On 11 July, three nymphs (one 4th instar and two 5th instars) of the
snakeweed grasshopper, Hesperotettix viridis viridis, were collected for comparison with A.
A sea of mesquite, fringe sage, and
snakeweed have swallowed the remaining adobe ruins, allowing only the tops of the crumbling buildings to reach for the first rays of the sun.
if any plant does move in, it is likely to be a tap-rooted forb (for example, a so-called noxious weed like leafy spurge, thistle, knapweed or
snakeweed) or a shrub like rabbitbrush or sage.
Apache plume (Fallugia paradoxa), wax current (Ribes cereum), skunkbush sumac (Rhus trilobata), Diamond Valley suncup (Camissonia gouldii), and California brickellbush (Brickellia californica) were most characteristic of young ecosystems; while blue grama grass (Bouteloua gracilis), squirreltail (Elymus elymoides), broom
snakeweed (Gutierrezia sarothrae), rose heath (Chaetopappa ericoides), Abert's creeping zinnia (Sanvitalia abertii), and pingue rubberweed (Hymenoxys richardsonii) were most characteristic of older ecosystems (Table 3).
understory plants included a thin mantle of dry grasses, Broom
snakeweed (Gutierrezia sarothrae), Graham's Mimosa (Mimosa grahamii), and a scattering of Palmer's century Plant (Agave palmeri); cholla cactus (Cylindropuntia sp.), Rainbow cactus (Echinocereus pectinatus), Pancake Nipple cactus (Mammillaria heyderi gummifera), and prickly pear cactus (Platyopuntia sp.) (Tom Van Devender pers comm., USDA 2012).
Low shrub communities primarily consisted of two species of rabbitbrush (Chrysothamnos spp.) and
snakeweed (Gutierrezia sarothrae).
Shallow rills through the Laate Orchard and the Lalio cornfield were filled with fine woody material from rubber rabbitbrush (Chyrsothamnus nauseosus) and broom
snakeweed (Gutierrezia sarothrae).
Two women, Anna Pierce, a midwife and her assistant, Aunt Shawnee,demonstrated that milk from a cow fed
Snakeweed killed a calf which consumed the milk....
The rancher (with a few honorable exceptions) is a man who strings barbed wire all over the range; drills wells and bulldozes stock ponds; drives off elk and antelope and bighorn sheep; poisons coyotes and prairie dogs; shoots eagles, bears, and cougars on sight; supplants the native grasses with tumbleweed,
snakeweed, povertyweed, cowshit, anthills, mud, dust, and flies.
Snakeweed (Gutierriza sarothrae) was negatively affected by increased frequency of clipping, steadily decreasing between years by -0.3% with no clipping to -4.0% at the heaviest frequency of clipping (Table 2).
The three most common dominant herbaceous species were Artemisia tridentata (big sagebrush), Gutierrezia sarothrae (
snakeweed), and Bromus tectorum (downy chess grass); and the three most common dominant overstory and understory species were Juniperus monosperma (one-seed juniper), d.
