The 2 weeks field studies during June of 1987 continued work on that part of the previously stated objectives (e.g. McKnight, Harper, & McKnight, 1986) concerned with the inventory of fungal species in the Wyoming national parks, particularly Grand Teton National Park. The specific objectives were to (1) study species of the genus Cortinarius, section Leprocybe, particularly those in the subsection Zinziberati to further clarify species concepts and relationships of species collected earlier, especially those of the 1983 and 1987 collecting seasons; (2) obtain illustrations of species for a revision of the previously published Checklist (McKnight, 1982) and a fieldguide of common species in the Grand Teton-Yellowstone area now in preparation.

The 6 weeks field studies during the summer of 1987 relate to that part of the previously stated objectives (e.g. McKnight, Harper, & McKnight, 1986) concerned with the inventory of fungal species in the Wyoming national parks, particularly Grand Teton National Park. With the return of Dr. Meinhard Moser, University of Innsbruck, Innsbruck, Austria, we intended to concentrate on the Hymenomycete genus Cortinarius. The range of species studied was broadened significantly by the shorter visits of two additional collaborators, Dr. Harry Thiers, University of San Francisco, San Francisco, CA, and Dr. Joe Ammirati, University of Washington, Seattle, WA.

The 1989 field studies continue the inventory of macrofungi known to occur in the Grand Teton-Yellowstone Park area. The long-term objectives of this study are: 1. to determine which species grow in forest, range, and pasturelands in and around Grand Teton National Park; 2. to gain a better understanding of their role in the ecosystem; and 3. to prepare descriptions, keys, and illustrations for the common species.

The primary overall objective of inventorying the macrofungi growing in and around Grand Teton and Yellowstone National Parks was partially achieved with the published checklist (McKnight 1982) and additions from the 1982 Research Center Annual Report (McKnight, Harper, & McKnight 1984). The intensive collecting of the 1982 fruiting season including a 12-week phenological study at 11 selected sites left many species unidentified and numerous others observed but not collected, or with inadequately annotated collections made. Litter and soil moisture data for the 11 study stands are also given in the 1982 annual report cited above, as well as data on 15 overstory and understory vegetation and soil parameters. Field studies in the Parks during the summer of 1983 concentrated on (1) identification of chlorophyllous and vascular plants at the 11 sites selected for concentrated study in 1982; (2) quantitative estimates of chlorophyllous plant cover and height; (3) estimates of site quality; (4) collections of composite soil samples; and (5) additional records of macrofungi for the Parks with supporting data in the form of photographs, drawings, and annotations.

We explored how Yellow Warblers (Dendroica petechia) alter their songs when encountering noise in Grand Teton National Park. Different strategies for avoiding signal masking are used by other species of birds, yet there is a lack of information of birds’ responses to higher noise levels–above 65 dB; such levels are often found in National Parks that have many visitors. In this study, we investigated singing behavior of Yellow Warblers when facing noise that ranged from 30 dB to 80 dB. In these preliminary results, we found that some features of Yellow Warblers did not appear to change with background noise level, including mean minimum frequency, bandwidth and song length. Other song features we studied did show small but statistically significant changes with higher background noise, including the peak frequency and the mean minimum frequency, both of which were significantly negatively correlated with the level of background noise. This result is different from the positive correlations that are typically observed. We speculate that this difference is due to the very high dB levels of background noise that we observed.   Featured photo bywagon16 on Flickr. https://flic.kr/p/G2W6Bk

Concessioners play an important role in park and protected area management by providing visitor services. Historically, concessioners were criticized for their negative impacts on environmental sustainability. However, due to policy changes, technological advances, and shifting market demands, there is a need to reevaluate the role of concessioners in sustainable destination management in and around parks and protected areas. The purpose of this qualitative case study situated in Grand Teton National Park (GTNP), which was guided by social exchange theory, was to explore U.S. national park concessioners’ influence on sustainable development at the destination level from the perspective of National Park Service (NPS) staff, concessioners, and local community members. Sustainability was examined holistically as a multifaceted construct with integrated socioeconomic, cultural, and environmental dimensions. Twenty-three participants completed semistructured interviews. Researchers identified four thematic categories describing concessioners’ influence on sustainability; motivations and barriers to pursuing sustainability initiatives; and situational factors that facilitated concessioners’ sustainability actions. While participants commented on the negative environmental impacts of concessioners and their operations, these data suggest that concessioners were working individually and collaboratively to promote environmental, socioeconomic, and cultural sustainability in and around GTNP. Some concessioners were even described as leaders, testing and driving the development of innovative sustainability policies and practices. These actions were motivated, in part, by contractual obligations and profit generation. However, concessioners also had strong intangible motivators, such as intrinsic values and a strong sense of community, that drove their positive contributions to sustainability. Based on these data, we recommend that those involved in future theoretical and practical work with concessioners acknowledge the importance of both tangible and intangible motivators when attempting to promote higher levels of sustainability achievement and collaboration. This will become increasingly important as land management agencies continue to embrace strategies beyond the traditional “parks as islands” approach to management. Additionally, future work should explore more specifically the role of policy, conceptualizations of sustainability, and private industry sponsorship in promoting concessioners’ contributions to sustainability, especially in collaborative settings. This work is needed to understand if and how these observations generalize to other contexts.

This study attempts to inventory the mushrooms and related fungi of the Park and to assemble correlative data useful in park resource management and utilization. It is directed toward (1) determining what species of higher fungi grow in and around Grand Teton National Park; (2) appraising their role in the ecosystem; and (3) preparing descriptions, illustrations, and where possible, keys for the common species. Fungi included are mostly Ascomycetes and Basidiomycetes with large or otherwise conspicuous fruiting bodies. Collecting is not confined to Grand Teton National Park but includes sites with similar ecology in the areas surrounding the Park.

This study was initiated in order to determine the population status of bighorn sheep (Ovis canadensis) in the Teton Range. Intensive field studies were initiated in the summer of 1978 and will be continued during the winter of 1978-79 in order to delineate the distribution of sheep and to relate this distribution to habitat factors which affect seasonal distributions. Additionally, information on the history of bighorn sheep has been sought through interviews of longtime residents of the several valleys surrounding the Teton Range.

With the accelerated use of our national parks there is growing concern over the impact this increased visitation might have on their flora and fauna. For this reason it is important to gather baseline data on the biota for future management and interpretive programs. Two species of concern in Grand Teton National Park are the bald eagle (Haliaeetus leucocephalus) and osprey (Pandion haliaetus).
