A landscape-scale assessment of plant communities, hydrologic processes, and state-and-transition theory in a Western juniper dominated ecosystem

Creator:

Petersen, Steven Lawrence

Abstract:

Western juniper has rapidly expanded into sagebrush steppe communities in the Intermountain West during the past 120 years. This expansion has occurred across a wide range of soil types and topographic positions. These plant communities, however, are typically treated in current peer-reviewed literature generically. The focus of this research is...

The influence of environmental attributes on temporal and structural dynamics of western juniper woodland development and associated fuel loading characteristics

Creator:

Johnson, Dustin D.

Abstract:

Since European American settlement of the Intermountain Region, dramatic changes in vegetation composition and structure have occurred in the sagebrush steppe ecosystem. Western juniper (Juniperus occidentalis spp. occidentalis Vasek), although indigenous to the Intermountain Region, has increased since the late 1800s. Considerable work has been done documenting juniper woodland expansion...
