Book Big Sagebrush

Download or read book Big Sagebrush written by Bruce Leigh Welch and published by . This book was released on 2005 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pioneers traveling along the Oregon Trail from western Nebraska, through Wyoming and southern Idaho and into eastern Oregon, referred to their travel as an 800 mile journey through a sea of sagebrush, mainly big sagebrush ( Artemisia tridentata). Today approximately 50 percent of the sagebrush sea has given way to agriculture, cities and towns, and other human developments. What remains is further fragmented by range management practices, creeping expansion of woodlands, alien weed species, and the historic view that big sagebrush is a worthless plant. Two ideas are promoted in this report: (1) big sagebrush is a nursing mother to a host of organisms that range from microscopic fungi to large mammals, and (2) many range management practices applied to big sagebrush ecosystems are not science based.

Book Masters Theses in the Pure and Applied Sciences

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Chemical Control of Big Sagebrush in Central Wyoming Classic Reprint

Download or read book Chemical Control of Big Sagebrush in Central Wyoming Classic Reprint written by N. A. Kissinger Jr. and published by Forgotten Books. This book was released on 2018-09-08 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Chemical Control of Big Sagebrush in Central Wyoming The concentrations of cattle on the sprayed plots was probably due only to the increased supply of available forage. On July 25 the grasses in the Sprayed plots had been grazed nearly twice as heavily as those in the unsprayed check plots. This suggests that some provision should be made in the sagebrush-spraying program to control grazing where only a small part of the range can be sprayed in any 1 year as may often be the case. Concentration of cattle on sprayed areas may result in damage to the non-shrubby species and encourage a reinvasion of the sagebrush or other undesirable plants.

Book Reestablishment of Wyoming Big Sagebrush Using Container Grown Seedlings

Download or read book Reestablishment of Wyoming Big Sagebrush Using Container Grown Seedlings written by David Casey Balthrop and published by . This book was released on 2016 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reestablishing Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) following a wildfire has proven difficult in many areas of the western United States and created the need to implement new restoration strategies. This project tests various methods that can be implemented to improve growth and survival rates for transplanted seedlings as well as the use of high seeding rates in hopes of improving the success of revegetation efforts. Chapter 1 is a synthesis of previous research conducted and provides background information for the subsequent sections. Chapter 2 walks through the process of producing sagebrush seedlings. From seed collection, cleaning and germination to greenhouse growth procedures and planting methods it describes the steps from start to finish. Chapter 3 is an analysis of the main scientific experiment and aims to determine which planting method results in the highest overall survival and production rate for outplanted seedlings. Data yielded from this study can be used to establish Best Management Practices (BMPs) for transplanting big sagebrush in eastern Wyoming rangelands heavily dominated by perennial grasses. The fourth chapter is a concise summary of the results from a small scale broadcast seeding experiment implemented on the site; incorporating high seeding rates and the use of snow fencing. And lastly, to show the feasibility and cost of transplanting Wyoming big sagebrush at a landscape level Chapter 5 summarizes the labor, materials and resources needed. Chapter 5 can be used by land managers, private landowners and restoration practitioners to estimate the amount of material and labor needed in order to trend a large area back to suitable sage-grouse habitat.

Book Response of Wyoming Big Sagebrush Artemisia Tridentata Ssp Wyomingensis to Defoliation of Understory Grasses and Drought

Download or read book Response of Wyoming Big Sagebrush Artemisia Tridentata Ssp Wyomingensis to Defoliation of Understory Grasses and Drought written by Teal Mackenzie Purrington and published by . This book was released on 1992 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water potential, leaf conductance, growth, nitrogen content, and seedling survival of Wyoming Big Sagebrush (Artemisia tridentata ssp. wyomingensis) following defoliation of the herbaceous understory were assessed during two growing seasons. Precipitation was 107% and 63% of the long-term mean (283 mm) in 1989 and 1990, respectively, which presented an opportunity to study impacts during a drought and a non-drought year. Response of Artemisia was measured on a site seeded to Agropyron desertorum in the late 1960s, and a native site with Stipa thurberiana, Festuca idahoensis and Poa sandbergii in the understory. The two sites were analyzed as separate experiments. The dry year had a significant effect on plant water relations and growth of Artemisia on both sites. Pre-dawn water potentials averaged 1.23 MPa more negative on the seeded site and 1.22 MPa more negative on the native site in 1990 compared to the previous year. Mid-day water potential averaged 1.22 MPa more negative on the seeded site and 1.13 MPa more negative on the native site in 1990 compared to 1989. Morning leaf conductance in 1990 was 61% lower on the seeded site and 51% lower on the native site than in 1989. Mean afternoon leaf conductance in the drought year was 62% less on the seeded site and 63% less on the native site. Nitrogen content in current year's growth was reduced 29% on the seeded site and 18% on the native site from 1989 to 1990. Vegetative and reproductive shoot (stem plus leaves) weights were reduced by over 80% in 1990 compared to 1989. Other production variables showed similar reductions in the drought year. Nitrogen content was 11% greater in current year's growth from shrubs on control as opposed to defoliated plots on the native site in 1989. Shrubs on control plots had 8% heavier reproductive stems per unit of canopy, and 7% longer vegetative stems than shrubs on defoliated plots in 1989 on the seeded site. Shrubs on control plots had 18% fewer annual leaves per unit of vegetative shoot, but 12% more primary ephemeral leaves per vegetative shoot than shrubs on defoliated plots in 1990 on the seeded site. In 1990, shrubs on control plots on the seeded site had 11% more ephemeral leaves per vegetative shoot while shrubs on the control plots on the native site had 8% fewer ephemeral leaves per vegetative shoot. Large shrubs generally had more and heavier leaves, and longer and heavier stems than medium shrubs. Exceptions included large shrub lateral stems were 30% shorter than those of medium shrubs, and large shrubs had 37% fewer annual leaves per vegetative shoot than medium shrubs in 1989 on the seeded site. Drought had substantial negative impact on water relations and growth of Wyoming big sagebrush, while defoliation of understory vegetation had little effect.
