The 1990 field season constituted the last of a three year study to survey the hypogeous fungi of Grand Teton National Park and the Greater Yellowstone ecosystem. The objectives were to: 1. collect and identify hypogeous fungi found in association with ectomycorrhizal tree hosts such as lodgepole pine (Pinus contorta), subalpine fir (Abies lasiocarpa), Douglas-frr (Pseudotsuga menziesii), quaking aspen (Populus tremuloides), and speckled alder (Alnus tenuifolia), and several species of willow (Salix sp.) throughout the area; and 2. to gain an initial understanding of the importance of these fungi as food for small mammals.

Since Grand Teton National Park adopted a natural fire policy in the early 1970's, four major fires have burned within the park which created a chronosequence of post-burn successional ecosystems. The burns encompassed forests varying in composition from Englemann spruce (Picea englemanil) /subalpine fir (Abies lasiocarpa) /lodgepole pine (Pinus contorta) (Beaver Creek, Mystic Isle) to Englemn spruce / subalpine fir (Waterfalls Canyon) to primarily lodgepole pine (Huckleberry Mountain).

Baseline information on the avifauna of the riparian communities in Grand Teton National Park is sparse. Consequently, the objective of this project is to collect information on the composition, density, distribution and habitat of the bird species inhabiting a portion of the black cottonwood, Populus trichocarpa, community in Grand Teton National Park. The study was initiated in June 1980 on a portion of the western floodplain of Pilgrim Creek. The southeast conner of this 300m x 400m (12ha) plot is identified by a metal post. This post can be located on a bearing line of 4° E of N. 77 mm from the fiducial center of the infrared aerial photo N 31 (U.S. Bur. of Reclamation Series B/Rl7, 7-16-79). This floodplain community is predominantly black cotton wood with scattered trees of quaking aspen, Populus tremuloides, engelman spruce, Picea engelmannii and lodgepole pine, Pinus contorta. In restricted moister areas several small patches of alder, Alnus incana occur under the larger trees and a few patches of willow, (Salix, sp.) are located in moist openings of the woodland.

An Avian Atlas for the State of Wyoming is being developed by the Wyoming Game and Fish Department. Baseline information on the avifauna of the riparian communities is especially sparse. Consequently, the objective of this project is to collect information on the composition, density, distribution and habitat of the bird species inhabiting a portion of the narrowleaf cottonwood, Populus angustifolia, community in Grand Teton National Park. The study was initiated in June 1980 on a portion of the western floodplain of Pilgrim Creek.

Burned Areas

An unexpected consequence of the 1988 Yellowstone fires was the widespread establishment of seedlings of quaking aspen (Populus tremuloides) in the burned forests, including areas outside the previous range of aspen (Kay 1993; Romme et al. 1997). Although aspen is the most widely distributed tree species in North America (Powells 1965), it is relatively uncommon and localized in distribution within Yellowstone National Park (Despain 1991). Most aspen stands in Yellowstone are found in the lower elevation landscapes in the northern portion of the park, and the species was absent - prior to 1988 -- across most of the high plateaus that dominate the southern and central park area. Aspen in the Rocky Mountain region reproduces primarily by means of vegetative root sprouting. Although viable seeds are regularly produced, establishment of seedlings in the wild is apparently a rare event due to the limited tolerance of aspen seedlings for desiccation or competition (e.g., Pearson 1914; McDonough 1985). In the immediate aftermath of the 1988 Yellowstone fires, there was a brief "window of opportunity" for aspen seedling establishment, as a result of abundant aspen seed production, moist weather conditions in spring and summer, and bare mineral soil and reduced plant competition within extensive burned areas (Jelinski and Cheliak 1992; Romme et al. 1997). We initiated this 3-year study in 1996 to address four questions about the aspen seedlings now growing in burned areas across the Yellowstone Plateau: (1) What are the broad-scale patterns of distribution and abundance of aspen seedlings across the subalpine plateaus of Yellowstone National Park? (2) What is the morphology and population structure -- e.g., proportions of genets (genetic individuals that developed from a single seed) and ramets (vegetative root sprouts produced by a genet) of various ages - in aspen seedling populations? (3) What are the mechanisms leading to eventual persistence or extirpation of seedling populations along an elevational gradient, particularly with respect to ungulate browsing and plant competition? (4) What is the genetic diversity and relatedness of the seedling populations along gradients of elevation and substrate?

As of this writing we have completed the third year of a cooperative UW/GTNP archaeological project, with 1998 being the first season. The primary purpose here is to provide a brief overview of some of the accomplishments of that first field season. This basic "UW/NPS Research Center Annual Report" format then will have two more installments for 1999 and 2000. More attention is given in this first report to background such as the history of archaeological research in Grand Teton National Park, while subsequent reports will emphasize other types of information. No attempt is made here to provide detailed discussions of field methods, project environmental settings, or individual sites, features, and artifacts. Such description would be standard in some archaeological reporting formats, but much more detailed discussions, and more synthesis of regional prehistory, is being assembled in a series of project­ specific compliance reports, conference papers, seminar papers, a graduate student thesis, and journal articles. The possibility of a cooperative University of Wyoming/Grand Teton National Park venture was first proposed by Robert Schiller, Director of the Science and Resource Management Division at Grand Teton. It was apparent that a series of mutual benefits could result, where University archaeologists would aid the Park with its increasing number of federally-mandated compliance projects while at the same time providing student training and employment opportunities. In addition, nearly 400 sites had been located in Grand Teton National Park and the adjacent Rockefeller Parkway at that time, but very little current information was available for many of them and modem re­evaluations were needed. At the same time, these various "applied research" compliance surveys and site revisit projects could contribute to broader theoretical frameworks relevant to our research throughout the region. The investigation of prehistoric settlement patterns and other aspects of landscape utilization is enhanced even by basic surface evidence, for example. The 1998 UW/GTNP CAP crew included the writer, UW Anthropology graduate students Alan Bartholomew and Mike Peterson, and volunteer archaeologist Jill Anderson. All work in Grand Teton has been coordinated with Park Historian Mike Johnson and USFS/GTNP Archaeologist Merry Haydon. Dave Hammond with the GTNP GPS unit and several other individuals aided with our projects. Yellowstone National Park Archaeologist Ann Johnson provided needed advice and materials on several occasions. All of our work was only possible because of the availability of the AMK Science Camp facilities, and the hospitality provided there by Hank and Mary Ann Harlow and their staff.

We report long-term patterns of quaking aspen (Populus tremuloides Michx.) recruitment for five ungulate exclosures in the northern ungulate winter range of Yellowstone National Park. Aspen recruitment was low (<3 aspen·ha−1·year−1) in the mid-1900s prior to exclosure construction due to herbivory by Rocky Mountain elk (Cervus elaphus Linnaeus, 1758) but increased more than 60-fold within 25 years after exclosure construction despite a drying climatic trend since 1940. Results support the hypothesis that long-term aspen decline in Yellowstone’s northern range during the latter half of the 20th century was caused by high levels of ungulate herbivory and not a drying climate. Gray wolves (Canis lupus Linnaeus, 1758) were reintroduced during 1995–1996. For the period 1995–2012, we summarized annual predator–prey ratios, ungulate biomass, and drought severity. The average density of young aspen increased from 4350 aspen·ha−1 in 1997–1998 to 8960 aspen·ha−1 in 2012; during the same time period, those >1 m in height increased over 30-fold (from 105 to 3194 aspen·ha−1). Increased heights of young aspen occurred primarily from 2007 to 2012, a period with relatively high predator–prey ratios, declining elk numbers, and decreasing browsing rates. Consistent with a re-established trophic cascade, aspen stands in Yellowstone’s northern range have increasingly begun to recover.

Sound Management

A research project was initiated in the summer of 1980 to study re-establishment of vegetation following prescribed burning in Glacier National Park (GNP), Montana. The problem of conifer re-establishment following disturbance such as fire has often been associated with inadequate moisture conditions (Ronco 1970). The ecophysiological characteristics of a particular species may determine its success in establishment as well as its successional role in a community. Since the goal of prescribed burning is often to "set back" succession in a particular community, knowledge of the ecophysiological characteristics of the species involved is vital to the development of sound management policy. Three conifers common to GNP and the Rocky Mountains, Abies lasiocarpa, Picea engelmannii, and Pinus contorta, were monitored throughout the season to develop baseline information on their water relations at exposed sites, similar to postburn situations, compared to normal understory situations. Although, successional patterns concerning these three conifers have been well documented (Stahelin 1943, Langenheim 1962, Day 1972, Whipple and Dix 1979), their ecophysiological adaptations influencing establishment and succession following a burn or other disturbance has received little attention.
