Crested Wheatgrass Agropyron desertorum (A.cristatum) Crested Wheatgrass is a cool season, vigorous growing, and drought tolerant, winter hardy, perennial bunchgrass which grows to a height of 1 to 3 feet. It’s dark green leaf blades taper to a sharp point and extend sharply upward from the base during the early part of the growing season. The leaf sheaths, which wrap tightly around the stems, are longer than the internodes, and have a smooth surface. The seed heads are approximately two inches long; have an unusual flat cockscomb or crested shape; and taper toward the tip, with the axis showing fine hairs. The grass has an extensive fibrous root system which penetrates as much as six feet. This gives the plant an advantage over weeds and enables it to do well in areas of as little as 12 inches of annual rainfall. Its drought tolerance, winter hardiness, and ability to withstand grazing, combined with high palatability and nutritious forage make it a valuable plant. There are two distinct species of crested wheatgrass – Standard (A. desertorum), and Fairway – A. cristatum). Crested wheatgrass should generally be seeded below 7,000 feet elevation. Crested wheatgrass does well on shallow to deep, moderately course to fine textured, moderately well to well drained soils. Under saline conditions, vigor and production are reduced.

Elymus Elymoides Crested Wheatgrass Agropyron Desertorum
Reclamation of Pipeline Right-Of-Ways on Rangelands Charlie D. Clements, James A. Young and Dan N. Harmon Introduction USDA, Agricultural Research Service 920 Valley Rd. Reno NV 89512 [email protected] In the mid 1990’s a large diameter natural gas pipeline was constructed across western Nevada. Reclamation of such right-of-ways are challenging because of both the severity and the linear nature of the disturbance. During construction, pipelines and equipment (Fig. 1) are highly visible at a landscape level to the general public, therefore attracting concerns and reclamation suggestions from a host of interest groups. The construction contractor invited us to set up plots and conduct research concerning the reclamation of their pipeline disturbance. Table 1. Plant material used in the pipeline reclamation effort. Common Name _____ Scientific Name Antelope Bitterbrush Purshia tridentata Figure 3. Lower pipeline site 6 years after the initial reclamation seeding. Basin Big Sagebrush Artemisia tridentata Basin Wildrye Leymus cinereus Big Bluegrass Poa secunda Bluebunch Wheatgrass Pseudoroegneria spicata Figure 1. Heavy equipment used in pipeline construction is very visible as well as the disturbance.

Antelope bitterbrush, basin big sagebrush, ‘Immigrant’ forage kochia,and needle-and-thread grass were some of the planted species that successfully established. Figure 2. Pipeline site the first year after reclamation seeding effort. Results and Discussion It is a common practice to rest sites from livestock grazing for 2 years following such efforts, but Methods this is hard to do following pipeline disturbances because the disturbances are so narrow and linear in nature.

SUMMARY A 45-day plant collection expedition to the USSR by D. R. Dewey, A. P. Plummer, and Laurie Law netted about 1,100 seed collections of range-forage grasses, legumes, forbs, and shrubs. The Soviets provided land transportation and an escort of several scientists and administrators throughout the trip. The collectors were usually housed in hotels and made daily trips to collect native vegetation in surrounding areas usually within a 100-km radius. Almost 3 weeks (July 20 - August 6) were spent in the Stavropol Kray in the northern foothills of the Caucasus Mountains.

Reference Plant List
APPENDIX J NATIVE & INVASIVE PLANT LIST The following tables capture the referenced plants, native and invasive species, found throughout this document. The Wildlife Action Plan Team elected to only use common names for plants to improve the readability, particular for the general reader. However, common names can create confusion for a variety of reasons. Common names can change from region-to-region; one common name can refer to more than one species; and common names have a way of changing over time. For example, there are two widespread species of greasewood in Nevada, and numerous species of sagebrush. In everyday conversation generic common names usually work well. But if you are considering management activities, landscape restoration or the habitat needs of a particular wildlife species, the need to differentiate between plant species and even subspecies suddenly takes on critical importance. This appendix provides the reader with a cross reference between the common plant names used in this document’s text, and the scientific names that link common names to the precise species to which writers referenced. With regards to invasive plants, all species listed under the Nevada Revised Statute 555 (NRS 555) as a “Noxious Weed” will be notated, within the larger table, as such. A noxious weed is a plant that has been designated by the state as a “species of plant which is, or is likely to be, detrimental or destructive and difficult to control or eradicate” (NRS 555.05). To assist the reader, we also included a separate table detailing the noxious weeds, category level (A, B, or C), and the typical habitats that these species invade.

Spotted Knapweed
Spotted knapweed (Centaurea maculosa Lam) : water, nutrients, plant competition, bacteria, and the seed head fly (Urophora affinis Frnfd.) by Stephen Anthony Kearing A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology Montana State University © Copyright by Stephen Anthony Kearing (1996) Abstract: Spotted knapweed, Centaurea maculosa Lam., is considered fay many to be the number one noxious weed in western Montana. A hydroponics study was conducted in Bozeman, MT to quantify water and nutrient uptake of spotted knapweed and two grass competitors. Spotted knapweed, western wheatgrass, Pascopymm smithii (Rydb.) Love, and a crested wheatgrass hybrid, Agropyron cristatum (L.) Gaert X Agropyron desertorum (Fisch. ex Link) Schult., were grown in a complete randomized block design, each in individual hydroponic drip systems with an inert rock wool media. The pots were weighed at each interval to estimate water use. Mean concentrations remaining in the system for nitrogen, phosphorous, and potassium were regressed against mean cumulative water use for each treatment. Spotted knapweed and western wheatgrass had similar slopes for nitrogen and potassium concentrations that were significantly lower than crested wheatgrass (t-test, P < = 0.05), suggesting that knapweed and western wheatgrass absorb nitrogen and potassium more efficiently than crested wheatgrass. Conversely, crested wheatgrass had a significantly lower slope for concentrations of phosphorous remaining in the solution (t-test, P = 0.01), suggesting crested wheatgrass absorbs more phosphorous per ml water than western wheatgrass or spotted knapweed. Spotted knapweed used more water throughout the experiment (P = 0.01), with differences being greatest during bolting. The combination of water and nutrient uptake rates help to explain spotted knapweed’s ability to compete for resources.

Discovery, Expression Profiling, and Evolutionary Analysis Of
DISCOVERY, EXPRESSION PROFILING, AND EVOLUTIONARY ANALYSIS OF CYNODON EXPRESSED SEQUENCE TAGS by CHANGSOO KIM (Under the Direction of Andrew H. Paterson) ABSTRACT Bermudagrass (Cynodon dactylon) is a major turfgrass species for sports fields, lawns, parks, golf courses, and general utility turfs in tropical and subtropical regions. Despite its ecological importance, much of its study has been dependent upon classical approaches. Information about Bermudagrass at the molecular level has been deficient although molecular information for other plants has been accumulated for the last two dacades. In the current study, we constructed a normalized cDNA library from leaf tissue of Bermudagrass in order to expand our knowledge of its transcriptome. We sequenced and annotated 15,588 expressed sequence tags (ESTs), which were deposited in the National Center for Biotechnology Information (NCBI) to be shared with other scientists. We also conducted cDNA array hybridization (macroarray) to profile genes responding to drought stress. A total of 120 and 69 genes were identified as up- and down-regulated, respectively. BLASTX annotation suggested that up-regulated genes may be involved in osmotic adjustment, signal transduction pathways, protein repair systems, and removal of toxins, while down-regulated genes were mostly related to basic plant metabolism such as photosynthesis and glycolysis. Using the cDNA sequences, we performed a comparative genomic study to gain new insight into the evolution of Bermudagrass. Results suggested that the common ancestor of the grass family experienced a whole genome duplication event at ca. 50.0 ~ 65.4 million years ago (MYA), before the divergence of the PACC and BEP clades at ca. 42.3 ~ 50.0 MYA.

C3 Grasses Have Higher Nutritional Quality Than C4 Grasses Under Ambient and Elevated Atmospheric CO2
Global Change Biology (2004) 10, 1565–1575, doi: 10.1111/j.1365-2486.2004.00833.x C3 grasses have higher nutritional quality than C4 grasses under ambient and elevated atmospheric CO2 RAYMOND V. BARBEHENN*,ZHONGCHENw ,DAVIDN.KAROWEz and A N G E L A SPICKARD§ *Departments of Molecular, Cellular and Developmental Biology and Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109-1048, USA, wSchool of Forestry, Northern Arizona University, Flagstaff, AZ 86011-5018, USA, zWestern Michigan University, Department of Biological Sciences, Kalamazoo, MI 49008-5410, USA, §Environmental Protection Agency, Ann Arbor, MI 48105, USA Abstract Grasses with the C3 photosynthetic pathway are commonly considered to be more nutritious host plants than C4 grasses, but the nutritional quality of C3 grasses is also more greatly impacted by elevated atmospheric CO2 than is that of C4 grasses; C3 grasses produce greater amounts of nonstructural carbohydrates and have greater declines in their nitrogen content than do C4 grasses under elevated CO2. Will C3 grasses remain nutritionally superior to C4 grasses under elevated CO2 levels? We addressed this question by determining whether levels of protein in C3 grasses decline to similar levels as in C4 grasses, and whether total carbohydrate : protein ratios become similar in C3 and C4 grasses under elevated CO2. In addition, we tested the hypothesis that, among the nonstructural carbohydrates in C3 grasses, levels of fructan respond most strongly to elevated CO2. Five C3 and ﬁve C4 grass species were grown from seed in outdoor open- top chambers at ambient (370 ppm) or elevated (740 ppm) CO2 for 2 months.
