A soil survey was conducted of the East Glacier, West Glacier and Lost Lake watersheds in July-September 1986. Procedures appropriate for an Order 3 soil survey were followed. Fifteen locations were surveyed and a total of 166 samples were analyzed. The 15 series are listed below, along with the soil classification and number of samples analyzed.

The soils map of GLEES watersheds is shown in chap. 5, fig. 5.1 and the map units are described in this Appendix.

This Appendix identifies macroinvertebrate species found in streams and lakes at GLEES during a preliminary qualitative survey conducted in the summer of 1988 by Dr. Boris Kondratieff. The littoral zones of each lake and each stream were sampled by hand-picking and with a triangle net. Insect voucher specimens are maintained in the Gillette Entomological Museum at Colorado State University in Fort Collins, CO. Asterisked species were found in East and/or West Glacier Lakes. Other species are not identified by location at GLEES, but this information is available from the voucher collection.

The species included in this list were collected from Lost Lake (L) and East Glacier Lake (EG) and West Glacier Lake (WGL) and identified by Richard Dufford, Phychologist, in 1988. The collection is maintained by Mr. Dufford in Fort Collins, Colorado. Samples were collected as an integrated sample from a water column at the deepest section of the lake.

This appendix provides a list of 230 vascular plant taxa that were field identified and/or collected over the period 1986-1990. Field identification was done by C.L. Simmons in 1986-87 (see Chapter 2). Subsequent taxa were field identified, collected, and verified by J.D. Haines and C.M. Regan in 1988-90. Voucher specimens were verified by taxonomists at the Rocky Mountain Herbarium. All taxa were collected in the upper GLEES area encompassing the watersheds of East and West Glacier Lakes and Lost Lake. A herbarium voucher collection of plant species found at GLEES is maintained at the...

Air quality is monitored continuously at GLEES. Air pollutants are considered an important component of the atmosphere that can have an effect on terrestrial and aquatic ecosystems. Atmospheric deposition of gases, wet deposition of chemicals in precipitation including snow and rain, and dry deposition of chemicals are all monitored at GLEES. Although GLEES is a relatively remote and unpolluted site, deposition of pollutants can be important. The effects of ozone on native vegetation in alpine and subalpine ecosystems is generally unknown, but relatively high concentrations of ozone have...

The Glacier Lakes Ecosystem Experiment Site (GLEES), a 600 ha research watershed at 3200-3400 m elevation in the Snowy Range of SE Wyoming, has been established to examine the effects of atmospheric deposition on alpine and subalpine ecosystems. This document provides preliminary data on the landscape habitats, floristics, geology, soils, aquatics, atmospheric environment, hydrology, snow, and air quality conditions occurring at GLEES. Checklists of vascular plants and plankton, detailed soils descriptions, and maps of geology, soils, vegetation, and topography are provided.

Daily fire growth maps display the growth of the 1988 fires in the Greater Yellowstone Area. Information and data sources included daily infrared photography flights, satellite imagery, ground and aerial reconnaissance, command center intelligence, and the personal recollections of fire behavior observers. Fire position was digitized from topographic maps using GRASS GIS software to construct a file of daily fire location in vector format, later converted to raster format for further analysis. The data base is available in electronic form.

Guiding principles based on conservation biology are applied in assessing ecosystem needs. Ecosystem, economic, and social needs are integrated in a decision model in which the guiding principles are used as a primary filter for evaluating proposed actions. Management practices consistent with the guiding principles are likely to lead to ecological, economic, and social well being, while those practices that are not consistent with the guiding principles risk species loss, degraded environments, and long term social problems.

In this study a cross-correlation statistic is used to analyse the spatial relationship among stand characteristics of natural, undisturbed shortleaf pine stands sampled during 1961-72 and 1972-82 in northern Georgia. Stand characteristics included stand age, site index, tree density, hardwood competition, and mortality. In each time period, the spatial cross-correlation statistic was used to construct cross-correlograms and cumulative crosscorrelograms for all significant pairwise combination of stand characteristics. Both the cross-correlograms and cumulative cross-correlograms identified...
