Gerdes for the degree of Master of Science in the Interdisciplinary Studies Program: Historic Preservation to be taken August 2004 Title: NEVADA FALL CORRIDOR: A CULTURAL LANDSCAPE REPORT Approved: Robert Z. Melnick This study describes existing conditions, evaluates significance and historic integrity, and recommends treatment strategies to preserve historic elements of the Nevada Fall Corridor cultural landscape in Yosemite National Park. It reports findings from field investigation that examined and inventoried landscape features such as stone retaining walls, treadway material, bridges and causeways, and water features on both current-use and abandoned trail segments. The site was examined numerous times over a three-month period, with a followup visit one year later. Libraries and other archives were consulted for written and photographic historic documentation, which were analyzed against current conditions. -

We in the mid-Atlantic states tend to complain in the summer about the heat, and in the winter about the cold, but are generally happy with spring and fall, except when it rain excessively. Here in Virginia the humidity can be overwhelming at times also, but the old saying is “stick around a few days and the weather will change.” We are lucky to have the mountains, ocean, rivers, lakes, and many activities available within a short distance from us.

This includes fostering sound use of our land and water resources; protecting our fish, wildlife, and biological diversity; preserving the environmental and cultural values of our national parks and historical places; and providing for the enjoyment of life through outdoor recreation. The Department assesses our energy and mineral resources and works to ensure that their development is in the best interests of all our people by encouraging stewardship and citizen participation in their care. The Department also has a major responsibility for American Indian reservation communities and for people who live in island territories under U.S. administration. -
LITERARY NONFICTION and the NATIONAL PARK MOVEMENT, 1864-PRESENT Lindsay Dunne
Abstract Title of Dissertation: DEFINING PLACES: LITERARY NONFICTION AND THE NATIONAL PARK MOVEMENT, 1864-PRESENT Lindsay Dunne Jacoby, Doctor of Philosophy, 2014 Dissertation directed by: Professor Jeanne Fahnestock and Professor Scott Wible Department of English The canon of American “Nature writing” has long been recognized for its influence on environmental policy, but the role of specific works in shaping environmental discourse and altering material circumstances has yet to be fully understood, especially from a rhetorical perspective. In response, this dissertation explores how works of Nature writing have functioned as persuasive arguments of definition within the National Park movement. It analyzes how literary nonfiction texts promoted a public understanding of specific landscapes and redefined them as worthy of preservation. The idea of rhetorical ecology underlies this analysis: rather than relying on the commonplace idea that a single author writing a single text can influence an environmental policy, the dissertation traces how a work of literary nonfiction operates within a complex system of texts, writers, readers, institutions, objects, and history. The four main case studies demonstrate how new definitions of place have emerged through works of literary nonfiction, each acting in relationship to a larger campaign that led to the preservation of an American landscape as a National Park: Yosemite, Great Smoky Mountains, Everglades, and Voyageurs. In these landmark campaigns, a prominent work of Nature writing, by a prominent author like John Muir, Horace Kephart, Marjory Stoneman Douglas, and Sigurd Olson, built upon and contributed to a definitional discourse that enabled people to see a specific landscape differently than it had been seen before. -
Modeling Mountain Pine Beetle (Dendroctonus Ponderosae) Oviposition

Bentz3* 1Department of Biology, Utah State University, Logan, UT 84322, USA, 2Department of Mathematics and Statistics, Utah State University, Logan, UT 84322, USA, and 3USDA Forest Service, Rocky Mountain Research Station, Logan, UT 84321, USA Accepted: 30 January 2019 Key words: bark beetle, climate change, fecundity, local adaptation, phenology, oviposition rate, synchrony, voltinism, Coleoptera, Curculionidae, Scolytinae, Pinus strobiformis Abstract Mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae, Scolytinae), is a significant forest disturbance agent with a widespread distribution in western North America. Popula- tion success is influenced by temperatures that drive phenology and ultimately the adult emergence syn- chrony required to mass attack and kill host trees during outbreaks. In addition to lifestage-specific developmental rates and thresholds, oviposition timing can be a source of variance in adult emergence synchrony, and is a critical aspect of mountain pine beetle phenology. Adaptation to local climates has resulted in longer generation times in southern compared to northern populations in common gardens, and the role of oviposition rate in these differences is unclear. Oviposition rates and fecundity in a northern population have been described, although data are lacking for southern populations. We assessed southern mountain pine beetle oviposition rates and fecundity in a range of temperatures using a non-destructive technique that included frequent X-ray imaging. We found that oviposition rate and fecundity vary independently such that a female with high oviposition rate did not necessarily have high fecundity and vice versa. -

Dendroctonus Beetles and Old-Growth Forests in the Rockies1 J. M. Schmid and G. D. Amman2 Abstract.-Dendroctonus beetles (Coleoptera: Scolytidae) are a major mortality agent in old growth pine, spruce-fir, and Douglas-fir forests of the Rocky Mountains. The frequency of recurring bark beetle epidemics depends on the size of the area being considered, how extensively the stand(s) was decimated by a previous epidemic(s), and how fast the stand(s) grows into the hazardous condition. -

Western Pine Beetle Meandering Egg Galleries
Western Pine Beetle Meandering egg galleries Name and Description—Dendroctonus brevicomis LeConte [Coleoptera: Curculionidae: Scolytinae] The western pine beetle attacks and kills mature ponderosa pine throughout much of its range. It is one of the smaller members of the genus Dendroctonus (only about 1/8 inch [3-5 mm] long), and is a fairly non-descript bark beetle; it is dark brown and cylindrical in shape (fig. 1). Host—Ponderosa pine; however, this beetle is never found east of the Continental Divide, and, within the Rocky Mountain Figure 1. Western pine beetle adult (Dendroctonus brevi- Region, it is active only in a narrow band in western Colorado. comis). Photo: Erich Vallery, USDA Forest Service-SRS-4552, Bugwood.org. Live Cycle—There are several generations per year of western pine beetle. This number varies with location, depending upon eleva- tion and latitude. The number of generations is tied directly to the length of the “growing season,” so in some portions of their distribu- tion, they will have two generations per year, whereas in other areas, there may be as many as four generations per year. Western pine beetles are virtually inactive during the winter months but as soon as the weather becomes warmer, they will increase their activity. The first sign of western pine beetle attack is the production of pitch tubes on ponderosa pines. The egg gallery that is constructed by western pine beetles is described as being “serpentine;” that is, it is a sinuous, winding gallery that can even cross itself at times (fig. 2). The beetles mate, and eggs are deposited along the margins of the central gallery. -
