Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers
Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers
Aspen Bibliography
Upland aspen (Populus spp.) forests contribute significantly to biodiversity in their circumboreal role as keystone species. As aspen ecosystems flourish or diminish, myriad dependent species follow suit. The 43-hectare Pando aspen (Populus tremuloides Michx.) clone in Utah, USA, is thought to be the largest living organism on earth, but is faltering due to chronic herbivory. Long-term resilience in aspen communities, including Pando, rests on successful recruitment of vegetative suckers that are nutritiously desirable to browsing ungulates. Here, I evaluate aspen reproduction alongside numerous vital indicators of Pando's status in the first trend assessment of this embattled iconic forest. …

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne
The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne
Human–Wildlife Interactions
The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …
Framing Contemporary U.S. Wild Horse And Burro Management Processes In A Dynamic Ecological, Sociological, And Political Environment, J. Derek Scasta, Jacob D. Hennig, Jeffrey L. Beck
Framing Contemporary U.S. Wild Horse And Burro Management Processes In A Dynamic Ecological, Sociological, And Political Environment, J. Derek Scasta, Jacob D. Hennig, Jeffrey L. Beck
Human–Wildlife Interactions
The Wild Free-Roaming Horses and Burros Act (WFRHBA) of 1971 established all “unbranded or unclaimed” equids on U.S. public lands as “living symbols of the historic and pioneer spirit of the West.” Today, >72,000 feral horses (Equus ferus caballus) and burros (E . asinus ; WHB) live on western U.S. public rangelands. The number of WHBs exceeds the Bureau of Land Management’s maximum Appropriate Management Level (AML) of 26,715 by a factor of approximately 2.7 and has nearly doubled from 2007–2015. The AML was set to balance WHB numbers with rangeland health and support other uses such as wildlife habitat …
Wetland Plants Of Great Salt Lake, A Guide To Identification, Communities, & Bird Habitat, Rebekah Downard, Maureen Frank, Jennifer Perkins, Karin Kettenring, Mark Larese-Casanova
Wetland Plants Of Great Salt Lake, A Guide To Identification, Communities, & Bird Habitat, Rebekah Downard, Maureen Frank, Jennifer Perkins, Karin Kettenring, Mark Larese-Casanova
All Current Publications
Wetland Plants of Great Salt Lake: a guide to identification, communities, & bird habitat is a wetland plant identification guide, resulting from collaborative research efforts about Great Salt Lake (GSL) wetland conditions and bird habitat. Dr. Rebekah Downard collected dissertation field data from GSL wetlands during 2012–2015, the majority of which informed this work. Dr. Maureen Frank contributed her guide to GSL wetland vegetation and how to manage native plants as high-quality habitat for birds. The intended purpose in producing this guide was to create an informative source that could assist researchers, land managers, birders, and wetland enthusiasts in identifying, …

All Current Publications
There are five essentials for successful ranch management. These essentials consist of: 1) A lifelong approach to management needs, both integrative and holistic. 2) Strive for continuous improvement of key resources. 3) Assemble and use good analysis and decision-making tools. 4) Wage war on cost. 5) Place an emphasis on marketing.
Oregon Aspen Project, Forest Restoration Partnership
Oregon Aspen Project, Forest Restoration Partnership
Aspen Bibliography
The Oregon Aspen Project was initiated in response to the decline of aspen groves in Oregon and throughout the Western United States, and the lack of information to guide managers interested in stewardship to enhance this resource. There were three central goals and accompanying objectives for this project which are listed below. The project accomplishments are provided below each bulleted objective

Energy Conservation With Irrigation Water Management, Robert Hill
Energy Conservation With Irrigation Water Management, Robert Hill
All Current Publications
Irrigators in Utah experienced rapidly increasing energy costs from the mid 1970s to the late 1980s. These costs remain relatively high. Those who are pumping from deep wells are particularly interested in ways to cut back on energy use without doing away with profitability or production

Assessing The Relative Utility Of Models Of Vegetation Dynamics For The Management Of Sagebrush Steppe Rangelands, Paul E. Hosten
Assessing The Relative Utility Of Models Of Vegetation Dynamics For The Management Of Sagebrush Steppe Rangelands, Paul E. Hosten
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The literature, long-term temporal data sets, and spatial data points surrounding livestock watering pints within rangeland communities wearer used to examine common assumptions and concepts used in models of vegetation dynamics. Of the stability concepts examined, the constancy concept was invalidated using long-term relict area data, whereas long-term data following disturbance indicated that sagebrush-dominated areas could be considered as resilient under circumstances examined. Pioshpere as well as relict and post-disturbance data indicated that the individualistic notion of vegetation change was favored. Species showing the most predictability (based on repeatability of abundance curves, and spatial and temporal serial correlations) were sagebrush …
Natural Pastures Of The Macquarie Region Of New South Wales: Their Origin, Composition And Management, David Leslie Michaelk
Natural Pastures Of The Macquarie Region Of New South Wales: Their Origin, Composition And Management, David Leslie Michaelk
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Two experiments were conducted in the semi-arid (400 millimeter annual rainfall) Macquarie region of New South Wales, Australia, at the Trangie Agricultural Research Station (31° 59'S; 147° S7'E), to examine (a) the way botanical parameters can be used to separate grazing and climatic impacts on range vegetation, and (b) how this delineation affects application of range science tenets (site, condition and trend) to different pasture types.
Two range sites were studied: Site 1, a light soil type, was dominated by annual grasses, legumes and forbs, whereas perennial grasses (mainly Chloris acieularis and Chloris truncata) dominated the heavy soils of …
An Economic Analysis Of Range Improvements On Saddle Creek Allotment And Curlew National Grasslands--With Special Consideration On The Effects Of Improvements On Wildlife Management, Jerry Russell Meyers
An Economic Analysis Of Range Improvements On Saddle Creek Allotment And Curlew National Grasslands--With Special Consideration On The Effects Of Improvements On Wildlife Management, Jerry Russell Meyers
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Range improvements for livestock were analyzed for the Curlew National Grassland and Saddle Creek Allotment. Increases in aum's which were a result of range improvements were calculated and valued at $4.00 each. Internal rates of return for both study areas were computed with a 15-year project life span for estimated grazing capacity and permitted grazing. Rate of return was then set at 10 percent to calculate project life span for both permitted grazing and estimated grazing capacity for the two areas.
Effects of range improvements for livestock on wildlife habitat were studied. Due to a lack of quantitative data, values …
