Restoration Of Aspen Woodland Invaded By Western Juniper: Applications Of Partial Cutting And Prescribed Fire, Jonathon D. Bates, Richard F. Miller
Restoration Of Aspen Woodland Invaded By Western Juniper: Applications Of Partial Cutting And Prescribed Fire, Jonathon D. Bates, Richard F. Miller
Aspen Bibliography
Western juniper (Juniperus occidentalis spp. occidentalis) woodlands are rapidly replacing quaking aspen (Populus tremuloides) stands throughout the northern Great Basin. Aspen stands provide important habitat for many wildlife species and contain a high diversity of understory shrubs and herbaceous species. We studies two juniper removal treatments to restore aspen woodlands in Kiger Canyon on Steens Mountain, Oregon.

Alternative Future Growth Scenarios For Conserving Open Space Along Utah's Wasatch Front: A Case Study For The Mountain Land Association Of Governments, Richard E. Toth
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Over the past 20 years, rapid suburban and second-home development along Utah's Wasatch Front has threatened to irreversibly alter the region 's character and quality of life. This rapid development has raised concern among federal, state, county and community leaders with respect to the protection of surface and subsurface water; public health, safety and welfare; public services and infrastructure, and open space. The major areas being developed include the valley edges and bottom lands, riparian zones, agricultural lands and bench areas. Since most of these areas are under private ownership, they are highly vulnerable to an array of development activities.
Quantifying Losses Of Understory Forage In Aspen Stands On The Dixie And Fishlake National Forests, Barton R. Stam
Quantifying Losses Of Understory Forage In Aspen Stands On The Dixie And Fishlake National Forests, Barton R. Stam
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The West has lost up to 60% of its historic aspen stands over the last century, probably as a result of the successional tendency of aspen to be replaced by coniferous species in the absence of periodic fires. One of several major impacts of this change is the loss of understory forage as conifer canopy cover increases. I measured understory biomass in aspen stands ranging from 0% to 81 % absolute conifer cover in the canopy and found that understory production declines exponentially as conifers replace aspen. I also did an economic analysis to determine the value of the forage …
Response Of A Peatland Ecosystem To Stratospheric Ozone Reduction In Tierra Del Fuego, Thomas Matthew Robson
Response Of A Peatland Ecosystem To Stratospheric Ozone Reduction In Tierra Del Fuego, Thomas Matthew Robson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Tierra del Fuego, at the southernmost tip of South America, is influenced by ozone depletion. The landscape of southern and western Tierra de! Fuego is dominated by peatlands; they are important locally and in the context of global climate change, because they store large quantities of organic carbon.
To determine the influence of solar ultraviolet-B radiation (UV-B) on a Tierra de! Fuego peatland, we selectively filtered solar UV-Bin ten pairs of plots. Polyfluorine filters were used to create the Near-Ambient-UV-B Treatment (90% solar UV-B), and polyester filters to create the Reduced-UV-B Treatment ( 17% solar UV-B). These filters were first …
Long-Term Environmental Effects Of Conifer Removal To Achieve Aspen Release In Near-Stream Areas Within The Northern Sierras, Kenneth W. Tate, Bobette Jones, Melanie Mcfarland, Tom Rickman, Al Vasquez

Aspen Bibliography
The advanced state of conifer encroachment in aspen stands in the Sierra Nevada and southern Cascades is retarding aspen regeneration, putting an estimated 70 plus percent of stands at immediate risk of extinction with a significant percentage of stands already lost.
