Landscape applications of machine learning: Comparing random forests and logistic regression in multi-scale optimized predictive modeling of American marten occurrence in northern Idaho, USA [Chapter 9]

Publications Posted on: December 04, 2018
The American marten (martes americana) is a species that is dependent on old conifer forest at middle to high elevations and is highly sensitive to habitat loss and fragmentation in a scale dependent fashion (e.g., Hargis et al. 1999; Wasserman et al. 2012a, b), and forest management is often influenced by considerations of how management will affect extent and pattern of marten habitat.

United States state-level population estimates: Colonization to 1999

Publications Posted on: August 01, 2018
The U.S. landscape has undergone substantial changes since Europeans first arrived. Many land use changes are attributable to human activity. Historical data concerning these changes are frequently limited and often difficult to develop. Modeling historical land use changes may be neccessary. We develop annual population series from first European settlement to 1999 for all 50 states and Washington D.C. for use in modeling land use trends.

Using an agent-based model to examine forest management outcomes in a fire-prone landscape in Oregon, USA

Publications Posted on: September 25, 2017
Fire-prone landscapes present many challenges for both managers and policy makers in developing adaptive behaviors and institutions. We used a coupled human and natural systems framework and an agent-based landscape model to examine how alternative management scenarios affect fire and ecosystem services metrics in a fire-prone multiownership landscape in the eastern Cascades of Oregon.

Terrestrial Ecological Unit Inventory technical guide

Publications Posted on: December 27, 2016
The purpose of this technical guide is to provide specific direction and guidance for conducting Terrestrial Ecological Unit Inventory (TEUI) at the landscape and land-unit scales. TEUI seeks to classify ecological types and map terrestrial ecological units (TEUs) to a consistent standard throughout National Forest System lands. The objectives, policies, and responsibilities for TEUI are contained in Forest Service Manual (FSM) 1940. U.S.

Calculating the configurational entropy of a landscape mosaic

Publications Posted on: September 16, 2016
Applications of entropy and the second law of thermodynamics in landscape ecology are rare and poorly developed. This is a fundamental limitation given the centrally important role the second law plays in all physical and biological processes. A critical first step to exploring the utility of thermodynamics in landscape ecology is to define the configurational entropy of a landscape mosaic.

Soils [Chapter 5]

Publications Posted on: May 12, 2016
This report describes the soils of the Lost Lake, West Glacier Lake, and East Glacier Lake watersheds of GLEES and presents the methods used in conducting both the field and laboratory work. In addition, general statements about the nature of the mapping units used in making the soil maps are provided.

Meteorology [Chapter 7]

Publications Posted on: May 12, 2016
GLEES is contained within the Snowy Range Observatory. This Observatory consists of many weather stations, precipitation monitors, and stream gages scattered throughout the Snowy Range. These sites have been operated by the Wyoming Water Research Center (WWRC) since 1968. Data from the sites are available from the WWRC and were last summarized by Wesche (1982).

Introduction [Chapter 1]

Publications Posted on: May 12, 2016
Wilderness ecosystems in the United States are federally mandated and set aside by the Wilderness Act. They are managed to minimize human impact using methods that leave these systems, to the extent possible, in their natural state uninfluenced by manipulation or disruption by humans.

Hydrology [Chapter 9]

Publications Posted on: May 12, 2016
Three Parshall flumes were installed within East and West Glacier Lakes watersheds during the summer of 1987. Each Parshall flume was prefabricated fiberglass construction fitted with a hypolon liner to bring as much groundwater flow as possible to the surface so that it could be measured by passing the water through the flume.

Aquatics [Chapter 6]

Publications Posted on: May 12, 2016
Within the GLEES boundary there are three alpine lakes and several streams and ponds. The selection of GLEES as a research site for investigating of the effects of chemical and physical climate change was in part based on the accessibility of these low alkalinity "sensitive" aquatic ecosystems. This chapter provides a brief description of the physical, chemical, and biological characteristics of the GLEES aquatic ecosystems.
