Assessing Invasive Plant Species As Threats In Mojave Desert Parks, Sara L. Mcpherson, Donovan J. Craig, Scott R. Abella
Assessing Invasive Plant Species As Threats In Mojave Desert Parks, Sara L. Mcpherson, Donovan J. Craig, Scott R. Abella
Graduate Research Symposium (GCUA) (2010 - 2017)
The invasion and persistence of exotic plant species threatens the natural features that national parks are designed to protect. For example, park managers have witnessed an increase in the frequency, extent and intensity of fires along with a reduction in native species richness and diversity. Many park managers are familiar with a suite of highly invasive plants, but lack a comprehensive and systematic way of prioritizing invasive plant species based on potential threats to the parks’ resources. We have entered into a collaborative project with the National Park Service’s Inventory and Monitoring program to develop an invasive plant early detection …
29 Years Of Vegetation Community Change Across Environmental Gradients In A Mojave Desert Mountain Range, Christopher L. Roberts, James S. Holland, Scott R. Abella
29 Years Of Vegetation Community Change Across Environmental Gradients In A Mojave Desert Mountain Range, Christopher L. Roberts, James S. Holland, Scott R. Abella
Graduate Research Symposium (GCUA) (2010 - 2017)
There is a great deal of uncertainty as to how biological communities respond to changes in land use and climate change, a situation particularly relevant in protected areas such as national parks that were designated to conserve specific biological features. Utilizing extant vegetation data sets with repeatable methodology can provide opportunities for insight into previous vegetation change and provide base line data for long-term monitoring projects useful for modeling vegetation community trajectories. We have relocated and resurveyed 106 sites from a vegetation community study initiated in 1979 in the Newberry Mountains, southern Nevada, within Lake Mead National Recreation Area managed …

Growing Alfalfa For Wildlife, Don Ball
Growing Alfalfa For Wildlife, Don Ball
Kentucky Alfalfa and Stored Forage Conference
Alfalfa has long been recognized as a superb forage crop, which is why it is widely grown for dairy cattle, horses, sheep, and many other types of domesticated forage-consuming animals. Reasons for its popularity include wide adaptation, excellent nutritive value, good yield potential, perennial growth habit, a long growing season, and the fact that (in association with Rhizobium bacteria) it is a nitrogen-fixing legume that does not require periodic applications of nitrogen fertilizer.
Alfalfa Varieties For The Future, Joe Bouton
Alfalfa Varieties For The Future, Joe Bouton
Kentucky Alfalfa and Stored Forage Conference
When breeding tomorrow’s alfalfa varieties, most groups employ a model of combining traditional plant breeding with biotechnology tools in order to incorporate useful traits. In this model, the conventional variety development process will be the method of choice for most traits where breeders have traditionally made progress such as adaptation, heading date, disease and insect resistance, general persistence conditions such as grazing and traffic tolerance, and even yield. It has been very successful in adding economic value to the forage and livestock operations of many producers (Bouton 2007). These traditionally developed varieties will also be used as the germplasm platform …
Do's And Don'ts In Grazing Alfalfa, Ken Johnson
Do's And Don'ts In Grazing Alfalfa, Ken Johnson
Kentucky Alfalfa and Stored Forage Conference
I want to discuss some of the issues in a talk I presented nearly twenty years ago. At that point we had been grazing Alfalfa about eight years and made some general remarks about the concerns I had at the time. I will look at these as presented then and how the thoughts may have changed.
Is There A Benefit To Alfalfa Balage?, Gary Bates
Is There A Benefit To Alfalfa Balage?, Gary Bates
Kentucky Alfalfa and Stored Forage Conference
Making hay in the mid-South has always been a difficult process. High humidity and rainfall often make drying a long, tedious, if not impossible proposition. Over the last few years there has been an increased interest in making round bale silage, or balage, from forage crops. Fermenting alfalfa for storage has several advantages and disadvantages over regular haymaking systems.
Alfalfa Hay For Horses, Robert Coleman
Alfalfa Hay For Horses, Robert Coleman
Kentucky Alfalfa and Stored Forage Conference
When horse owners consider hay for their animals, a number of criteria are generally considered. Of major importance is the hay must be free of mold and dust. It needs to contain nutrients needed by the horse and it must be palatable. If these criteria are met, the type of hay should not matter. However, that is not the case with many horse owners. When discussing the selection of hay, many owners first consider the type of hay. Can it be alfalfa or should it be a grass or how about a mix of grass and a legume. If a …
Value Of Alfalfa In Rotation, S. Ray Smith
Value Of Alfalfa In Rotation, S. Ray Smith
Kentucky Alfalfa and Stored Forage Conference
There are about 23 million acres of alfalfa in the US. Alfalfa plus other hay is the most valuable crop in the US, behind only corn and soybeans. In Kentucky alfalfa is planted on over 300,000 acres and is an economically important crop for beef and dairy farmers, cash hay producers, and provides tremendous benefits for subsequent crops. There are also many non-agricultural benefits to alfalfa.
Advances In Alfalfa Seed Coatings, Bill Talley
Advances In Alfalfa Seed Coatings, Bill Talley
Kentucky Alfalfa and Stored Forage Conference
The volume of alfalfa being sold as coated seed has been in the growth mode for several years. This growth is being fueled by greater acceptance from the producer, as well as the many value added components that are now labeled and being offered as seed treatments. Originally seed coatings were looked at as a better way to deliver rhizobia to insure plant nodulation. This is still one goal, but many more value added components are now labeled that offer better plant protection, increased water absorption, enhanced germination, and micro-nutrient availability, as well as insect and parasite control. Another area …
