Weed and Pest Districts Exist to Assist Landowners Weed and pest districts exist to assist landowners By Slade Franklin Unmanaged noxious weeds and pests can negatively affect agricul- ture, wildlife habitat, land values, and even human health. For example: • Annual forage loss from invasive weeds in pastures amounts to nearly $1 billion in the United States. • In 1937, a Mormon cricket outbreak in Wyoming caused $383,000 in crop damage – approximately $6 million in today’s money. • Plants such as tansy ragwort (Senecio jacobaea), silverleaf nightshade (Solanum elaeagnifolium), and Russian knapweed (Centaurea repens) are common in Wyoming and toxic to livestock. • Plants such as purple loosestrife (Lythrum salicaria L.), oxeye daisy (Chrysanthemum leucanthemum), and Dalmatian toadflax (Linaria genistifolia ssp. dalmatica) can destroy wildlife habitat by out-com- peting native plants. • In the Western states, an estimated 17 million acres of federal land are infested with noxious weeds, and the number is increas- ing at a rate of 4,000 acres per day. This is pretty scary news, and it’s hard to imagine what a small-acre- Photo by William M. Ciesla, Forest Health Management International Photo by William M. Ciesla, Forest age owner can do to make a difference; however, a visit to a county weed and pest control district office is an excellent way to start. Wyoming’s current weed and pest program is the result of more than 100 years of noxious weed laws. The original weed control program was enacted and signed into law by Wyoming Governor William Richards in 1895 and made it “…the duty of every person, company, association of persons, railway company, corporation and municipal or public corporation in this state to destroy…the noxious weeds hereinafter mentioned, namely: the Aaesola kali tragus, commonly known as the Russian thistle and the Canadian thistle.” Since then, the state’s weed and pest program has be- come as diverse as the different invasive species threatening the state.

This report presents the progress of the site’s landscaping and revegetation activities for the third quarter of 2020. The intent of these reports is to provide detailed information regarding the site’s efforts related to vegetation including vegetation of interim and permanent slopes and activities conducted for the on-site sage mitigation areas. Architerra Design Group continues to assist site personnel in evaluating current site conditions relating to vegetation and provide recommendations for future efforts. This report includes their assessment of the pilot sage vegetation area as well as recommendations for this area. Architerra’s evaluation is in addition to the required quarterly monitoring performed by our consulting biologist. 1.0 Interim Slopes For the purposes of this report, interim slopes are those defined as slope areas where no activities have taken place for 180 days or longer. CUP Condition 44A requires “a temporary hydroseed vegetation cover on any slope or landfill area that is projected to be inactive for a period of greater than 180 days”. 1.1 Hydroseeding Activities Based on the results of the trial project completed in August 2017, a 57-acre vegetative cover project using the approved seed mix was completed in mid- December 2017.

IN THE DRYLAND CROPPING SYSTEMS OF THE INLAND PACIFIC NORTHWEST Abstract by John Forrest Spring, Ph.D. Washington State University May 2017 Chair: Drew J. Lyon Russian-thistle (Salsola tragus L.) is one of the most troublesome weed species in the low- and intermediate-precipitation dryland wheat-fallow cropping zones of the inland Pacific Northwest (PNW). High levels of morphological diversity typify the species on global, continental and regional scales. Previous research in California found this variability to encompass a largely cryptic complex of five distinct species in populations of Salsola in that state.

Comparatively small modifications in the structure, habits and environ- ment of a plant are capable of changing it from a harmless dweller by the wayside to a most aggressive enemy of the agriculturist. The law of evolution holds in the case of weeds as certainly as with flowers and fruit; Nature is producing new varieties of our common garden weeds which every now and then appear, and temporarily conquer wide territories of culti- vated land. The so-called Russian thistle, or Russian cactus, poetically called by the Russian moujiks, ' 'the wind witch" belongs to the class of "tumble-weeds" and furnishes an excellent illustration of these dangerous modifications in plant structure.

    WEEDS RUSSIAN THISTLE Genus/species Salsola kali Synonyms Common: Tumbleweed Botanical: Kali tragus Family Chenopodiaceae Distribution Central and western All areas west of a line from N Minnesota southward to US, and coastal areas S Texas of eastern states Coastal areas of states east of Texas Scattered local areas of other eastern states Comments This annual weed is also known as Tumbleweed because the dried plants, a symbol of the American west, typically break away at the base and get blown about by the wind, spreading their seeds. It was introduced as a contaminant in flaxseed to America from its original home on the steppes along the Ural Mountains of Eurasia, and has spread to dry areas throughout most of the world. There may actually be a handful of closely-related species lumped within this name. Originally established in South Dakota, it is now a common weed throughout the western US, and can be found from near sea level to as high as 8500 feet. It is an annual plant reproducing from seeds, has a deep taproot, and grows to become a rounded bush ranging, depending upon growing conditions, from a foot in diameter to some 6 feet. During the early stages of growth, the leaves are about an inch in length, thin and fleshy while those produced on older plants are short, stiff and spine-tipped. The single, tiny flowers are produced at the bases of the leaves. Pollination is achieved by wind. The seeds are unusual in that they contain an embryo without stored food. In addition to inhalant allergy to the pollen, contact allergy to the foliage has been reported.
