Site Analysis

Grizzly bears have been moving slowly southward in the Tetons and increasing their abundance over the last 20 years. Their distribution is now expanding into areas previously occupied by black bears only that are heavily developed and receive proportionately more recreational use. At the same time, white pine blister rust and other human­caused factors may reduce bear food abundance in the near future. Grand Teton National Park is now positioned for an unprecedented interplay of bears, declining bear food sources, and humans in a relatively small temporal and spatial scale. In a new study designed to provide information critical to future black and grizzly bear conservation in this area, 6 spread spectrum technology (SST) GPS radio collars were deployed on black bears in the southern end of Grand Teton National Park in 2005. SST collars allow interrogation of the data in the GPS unit on a regular basis. GPS units were programmed to record positions every 90 to 190 minutes, and data were downloaded aerially on a weekly basis. Four female bears, two with cubs of the year, an adult male, and a subadult male provided the bulk of approximately 2700 positions obtained in 2005, about 1560 of which were visted for detailed site analysis. Sites visited were based on a randomly selected 24 hour period for each bear each week, and all sites were visited within a week of the location's recording. Efforts in 2006 will focus more intensively on site visits and associated data collection and analyses.

Two years after initiating the Be Bear Aware program, management at Grand Teton National Park (GRTE) engaged the Wyoming Survey & Analysis Center (WYSAC) at the University of Wyoming to complete an evaluation of the public information and education component of the program. The focus of this program is to change visitor behavior (e.g., engaging in proper food storage, responsible recreation) through education. The desired outcome is to minimize the probability of human-bear encounters and the potential for conflict in park with thriving black bear and grizzly bear populations. To evaluate the efficacy of the program, WYSAC researchers collected information on the visibility of Be Bear Award signs, access to and use of Be Bear Aware information, visitor knowledge of GRTE’s food storage policy, and recreating safely while in bear country. WYSAC researchers then developed a questionnaire and interviewed a randomized stratified sample of 634 park visitors during the summer of 2010. The results of this study should help park managers identify aspects of the Be Bear Aware program that are working and those that can be improved upon.

Eight in-service teachers and two instructors engaged in an inquiry-based geology field course from June 14 to 29, 2014 through Wyoming, South Dakota, and Nebraska. This team of learners spent three days in mid-June working in the Grand Teton National Park area. The UW-NPS facilities provide an excellent opportunity for participants to discover the natural history of the Teton Range, as well as close-out a few projects while sitting in a real chair, at a real table, a welcome change from our usual campground setting.

Grand Teton National Park is part of the known range of the North American river otter, however not much is known about this semi-aquatic mammal within the park. The results presented here are part of a larger project to investigate the potential of the river otter (Lontra canadensis) to serve as an aquatic flagship (species that engender public support and action) for the Greater Yellowstone Ecosystem. River otters, known for their charismatic behavior have the potential to serve as an aquatic flagship species to promote conservation of aquatic ecosystems. The primary objective of this portion of the study was to identify river otter latrines on portions of the Snake River, between Flagg Ranch and Jackson Lake, and between Jackson Lake Dam and Pacific Creek, collect river otter scats to determine diet of the river otter, and employ remote cameras to determine activity patterns of the river otters. Between 20 June and 1 July 2015, 26 river otter latrines were identified during shoreline surveys, 186 river otter scats were collected, and cameras were deployed at 6 latrines between 7 July and 24 August 2015. River otter scats have been cleaned and prepared for analysis, but have not all been processed to date. Camera traps recorded 222 images, of which 7% (n = 14) were of carnivores, 70% (n = 155) were of non-carnivore mammals, and 9% (n = 22) were of birds. River otters were detected at 1 of the 6 latrines, a total of 5 independent times during the study.

River Reach

This project had two components, with the first component providing a background for the second component. Water resources in Grand Teton National Park (GTNP) are both unregulated and regulated by human management. The Jackson Lake Dam and the ponds scattered across the park influence the flow of water. In the process of managing the water it is important to have knowledge of the different components of the streams through which the water flows. One component of this project was to examine the different segments of the major rivers in GTNP and identify the river forms that are displayed by the different reaches of the Snake River above and below Jackson Lake, Buffalo Fork and Pacific Creek. The river form can be segregated into three main categories; the single channel, the meandering channel and the braided channel (Knighton 1984). The different river forms are part of the overall structural composition of the river and can be used to delineate the segments or reaches of the river. The river continuum concept presented by Vannote et al. (1980) provides a theoretical background upon which to construct the river reach system. In 2007, Nelson (2007) completed a reach system project while investigating the fluvial geomorphology of the Snake River below Jackson Lake Dam (Figure 1.). His 20 river reaches provided a zonation of the river that incorporated a range of geomorphic features. This same type of system can be used throughout the GTNP so that researchers have a common spatial unit designation when referencing portions of the Snake River and its tributaries. Ackers (1988) in his work on alluvial channel hydraulics identified three dimensions of meanders that should be considered; width, depth and slope. He further agreed with Hey (1978) that there are nine factors that define river geometry and that these should be considered as well: average bank full velocity, hydraulic mean depth, maximum bank full depth, slope, wave length of bed forms, their mean height, bank full wetted perimeter, channel sinuousity and arc length of meanders. Nelson’s work (Nelson 2007) added another parameter by including a braiding index into the representation of river reach designations. In a more recent work, the Livers and Wohl (2014) study confirmed Nelson’s approach by comparing reach characteristics between glacial and fluvial process domains using similar reach designation characteristics to determine reach differences.
