Invertebrates are receiving an increasing amount of conservation attention across North America. Currently, about 40% of the animals listed under the U.S. Endangered Species Act (ESA) are invertebrates (www.NatureServe.org). The National Park Service and other agencies require better information on invertebrate faunas in order to effectively conserve this important group of animals. One way to prioritize invertebrate groups for study is to assess the number of rare taxa within a given genus. In this context, Oreohelix (mountainsnails) are a top priority because the genus is assumed to support a very high percentage of rare and endemic taxa. Additionally, Oreohelix species in Wyoming and surrounding states have been petitioned for ESA listing in the recent past. The diversity of Oreohelix forms in Wyoming is not well-understood, and the current taxonomy may not reflect the true pattern of diversity within the state. Therefore, we are studying both the morphology and genetic structure of Oreohelix in Grand Teton National Park to begin to understand the diversity of mountainsnails in the state. We collected Oreohelix from 4 locations in Grand Teton National Park. Based on shell and internal characteristics, all individuals were identified as O. subrudis. We are currently preparing specimens for DNA sequencing.

Trail System

This project investigated the history of the backcountry trail system in Grand Teton National Park (GTNP). In cooperation with GTNP Cultural Resources and the Western Center for Historic Preservation in GTNP, we located records describing the early development of the trail system. Only a few historical records describe or map the exact location of early trails, which prove useful when relocating trails today. The paper trail becomes quite rich, however, in revealing the story behind the practical development of Grand Teton National Park as it joined the National Park Service system.

The Mangum Plate consists of three fragments of elaborately embossed copper sheeting formed of separate parts overlapped and hammered together and riveted where necessary. The pieces were found in 1936 by Spurgeon C. Mangum on a knoll situated on his farm 5 miles northeast of Port Gibson, Mississippi, 1 mile south of Bayou Pierre (R 3E, Tn 12N, S 28). The site has since been acquired by the State of Mississippi for the National Park Service for development as a feature of archaeological interest along the Natchez Trace Parkway.

Abstract The historic Japanese flowering cherry trees planted around the Tidal Basin in Washington, DC, were given to the United States in 1912 as a gift from Japan, yet only a small portion of the original trees remain. In cooperation with the National Park Service, the U.S. National Arboretum clonally propagated a portion of these trees. DNA from these and other P. x yedoensis plants obtained from domestic commercial nurseries were compared using RAPD markers. Twenty-one 10-nucleotide primers yielded 80 repeatable bands that were used to assess genetic distances among the accessions. The genetic distances ranged from 0.65 to 1.0, with thirteen accessions identical at all loci tested. The most genetically dissimilar trees were P. x yedoensis accessions that were collected as seed in Japan. Accessions obtained from commercial nurseries including ‘Afterglow’, ‘Akebono’, and Yoshino were also dissimilar to the Tidal Basin trees. This study indicated that most of the older trees planted around the Tidal Basin are genetically very similar, but that variability in P. x yedoensis exists, especially in accessions collected as seed from Japan.

AbstractA canid dentary is described from the Pliocene Glenns Ferry Formation at Hagerman Fossil Beds National Monument, south-central Idaho, USA. The specimen possesses traits in alliance with and measurements falling within or exceeding those of Canis lepophagus. The dentary, along with a tarsal IV (cuboid) and an exploded canine come from the base of the fossiliferous Sahara complex within the monument. Improved geochronologic control provided by new tephrochronologic mapping by the U.S. Geological Survey-National Park Service Hagerman Paleontology, Environments, and Tephrochronology Project supports an interpolated age of approximately 3.9 Ma, placing it in the early Blancan North American Land Mammal Age. It is conservatively referred to herein as Canis aff. C. lepophagus with the caveat that it is an early and robust example of that species. A smaller canid, initially assigned to Canis lepophagus and then to Canis ferox, is also known from Hagerman. Most specimens of Canis ferox, including the holotype, were recently reassigned to Eucyon ferox, but specimens from the Hagerman and Rexroad faunas were left as Canis sp. and possibly attributed to C. lepophagus. We agree that these smaller canids belong in Canis and not Eucyon but reject placing them within C. lepophagus; we refer to them here as Hagerman-Rexroad Canis. This study confirms the presence of two approximately coyote-sized canids at Hagerman and adds to the growing list of carnivorans now known from these fossil beds.

<p>Aesthetics is a pillar consideration in historic preservation. Yet, purposing aesthetics for historic preservation ends seems to lag behind the opportunities. Utterly subjective, aesthetics poses challenges for the preservation community worldwide to moderate, accommodate, and purpose aesthetics in heritage programs. The challenges revolve around the assessment of aesthetical purposing in three domains. These domains include the community disposition towards accommodating aesthetics (advocacy), the criteria and strategies for assessing the aesthetic value of historic resources (signification), and, the standards for treating historic resources in preservation projects (interpretation). This study, therefore, assesses the trends for purposing aesthetics in historic preservation thought and practice through three platforms: advocating aesthetics, signifying aesthetics, and interpreting aesthetics. The study completed literature content analysis on aesthetics in general and aesthetics in historic preservation in particular. Further, because of the perspective of the study, the works of international and country preservation programs provided information relevant to advocacy, signification, and interpretation of aesthetics that have been refined by classification, comparison, and exemplification methods. Among others, these works include those of the International Council on Monuments and Sites (ICOMOS) and the U.S. National Historic Preservation Program in the National Park Service. The study culminated with general and platform-specific conclusions. First, as the three proposed platforms (advocacy, signification, and interpretation) maintain structural and serial relationships, they constitute a relevant and feasible framework for assessing aesthetical purposing. Second, as the aesthetical purposing assessment followed a broad, international perspective, the conclusions of the study are commensurate with the selective scope of information used from international and country preservation programs. Third, the contribution to aesthetical purposing at each of the three platforms can be measure only in general, and at times, subjective terms.</p><p><strong>Highlights:</strong></p><ul><li><p>Proposing aesthetical advocacy, aesthetical signification, and aesthetical interpretation as a platform framework to assess the purposing of aesthetics was feasible.</p></li><li><p>As aesthetical purposing was approached from a broad, international perspective, the conclusions of the study commensurate with the selective scope of information used.</p></li><li><p>The contribution to aesthetical purposing at each of the three platforms is hard to measure; however, the indications point to uneven contribution.</p></li></ul>

In 2011, the Organization of American Historians (OAH) released Imperiled Promise: The State of History in the National Park Service, a multi-year team-authored study commissioned by the NPS Chief Historian. The study offered twelve findings assessing strengths and challenges facing history practice across the agency, and made almost one hundred recommendations that aimed to support that work. The report’s fifth anniversary offers an opportunity to review how Imperiled Promise’s proposals have fared. We find that, although the report has been positively received and many of its perspectives and specific suggestions embraced, the persistent structural issues it identified continue to hinder full realization of the parks’ promise. The OAH, National Council on Public History (NCPH), American Historical Association (AHA), and other professional associations, as well as their members, must continue to advocate strongly and consistently for NPS history.
