The Suitability of Native Warm-Season Grasses for Equine
Introduced cool-season grasses are dominant in Virginia's grasslands, but their high digestible energy and non-structural carbohydrate (NSC) levels pose a risk for horses prone to obesity and laminitis. Native warm-season grasses (NWSG) have lower digestible energy and NSC levels that may be more …

Senescence of Native Perennial Warm Season Grasses Senescence Associated Switchgrass Transcriptome
… senescencing crops do not maximize the growing season as nutrient reallocation takes precedence. Chlorophyll degradation and nitrogen reallocation was observed to occur rapidly between mid to late September. Transcriptome analysis on early and late senescencing switchgrass cultivars reveals …

Can Beef Be Bee-Friendly? Using Native Warm-Season Grasses and Wildflowers in Pastures to Conserve Bees
… in the eastern U.S. rely primarily on cool-season forages that peak in biomass production in late spring, leading to a lack of forage in the summer months and increasing the costs of cattle production. Seeding pastures with a mix of native warm-season grasses and native wildflowers could …

Compatibility, Yield, and Quality of Warm-Season Grass-Legume Mixtures
… production in the mid-Atlantic region. Perennial warm-season grasses might provide a solution if managed for high quality. Experiments were conducted on separate well-established stands of Caucasian bluestem and 'Cave-in-Rock' switchgrass at the Kentland Farm near Blacksburg, VA. Stages of grass …

Nutritional Value of Warm- and Cool-Season Grasses for Ruminants
… and 4)orchardgrass (Dactylis glomerata L.). The warm-season grasses (bermudagrass and bluestem) were higher (P < .01) in fiber components than the cool-season grasses (tall fescue and orchardgrass). Bluestem was lower (P < .001) in CP, hemicellulose, and ash, and higher in NDF (P < .001), ADF (P …

Denitrification and organic carbon in a series of riparian buffers in the Bear Creek National Demonstration Watershed
… and its controlling factors were different under warm season grasses and introduced cool season grasses at different depths. Denitrification potential measured by the Denitrifier Enzyme Activity Assay (DEA), Total Organic Carbon (TOC), Total Nitrogen (TN), Dissolved Organic Carbon (DOC), …

Biomass assessment in the U.S. midwest using MODIS time-series
… in the United States. Switchgrass, a type a Warm Season Grasses, has been regarded as alternative resources instead of annual crops for obtaining the bioenergy. The study is to delineate annual crops and perennial crops (Warm-Season Grasses and Cool-Season Grasses) in the U.S. Midwest based …

Assessment of stockpiling methods to increase late summer and early fall forage biomass
… endophyte (MaxQ)) and four species of native warm-season grasses without N fertilization (switchgrass (Panicum virgatum L.), big bluestem (Andropogon gerardii Vitman), indiangrass (Sorghastrum nutans (L.) Nash), and little bluestem (Schizachyrium scoparium (Michx.) Nash)). Native warm-season …

Evaluation of Mixed-Vegetation Plantings As Avian Nesting Habitat in Eastern South Dakota
Mixtures of legumes and non-native cool-season grasses have long been planted as avian nesting cover on wildlife management units. However in the recent past, there has been a trend toward planting native warm-season grasses. In 2000, South Dakota Game, Fish and Parks (SDGFP) began planting …

Pheasant Production Using Wild Cocks and Penned Game-Farm Hens
… of nests was located in alfalfa than in warm-season grasses when a choice was available. Incident light readings were lower and density of vegetation was higher in alfalfa than in warm-season grasses. Pheasants were produced by using wild cooks and penned game-farm hens; however, this …

Assessing the costs and benefits of native plant species for electric transmission line right-of-way revegetation within the Tennessee Valley Authority power service area
… on associated rights-of-way (ROWs). Native warm season grasses (NWSG) are more expensive for ROW revegetation compared to typical exotic cool season grasses (ECSG), but they may alter the successional trajectory such that long-term maintenance costs are reduced. I conducted a cost-benefit …

Establishment of native plant species for livestock forage in silvopasture systems
… success of establishment of native cool and warm season grasses, and native forb and legume species in two different existing silvopasture systems -- pitch pine (Pinus rigida Mill.) x loblolly pine (Pinus taeda L.) hybrid and eastern American black walnut (Juglans nigra L.) -- with open …

The Influence of Switchgrass Establishment on Soil Organic Matter Pools in an Agricultural Landscape
… and declining soil fertility. Planting perennial warm season grasses is a useful management alternative to row crop agriculture because these species have been shown to be effective at increasing soil carbon storage and retaining nitrogen. The objectives of this research were to examine how …

Evaluation of alternative forage species to reduce risk for cow-calf production systems in the Appalachian region
… productivity is essential to reduce pasture seasonality and ensure available forage to meet the nutritional needs of livestock. This study explores the risk-buffering ability of warm-season forages to fill the summer slump gap in production of cool-season grasses. Small plot experiments were …

Effects of Burning and Cutting on Plant Diversity on Ozark Cedar Glades in Stone and Taney County, Missouri
… exposed bedrock, and are often dominated by warm season grasses, herbaceous dicots, and stunted trees and shrubs adapted to dry environments. As a result of fire suppression, glades have become overgrown with undesirable plants such as the eastern red cedar tree. Undesirable plants are those …

Effects of connectivity and regional dynamics on restoration trajectories for small mammal communities on Midwestern grasslands
… corridors. Patch size and seeding type (cool-season versus warm-season grasses) were not predictors of initial restoration trajectories. In 2011, populations of Microtus experienced a severe regional decline that might have reflected multi-year population cycles. During the crash, most …

Growing crops for biofuel and forage while conserving soil and water
… additional feedstocks, such as perennial warm-season grasses (WSG), maybe needed to meet the demands of these bioenergy facilities. Thus, the development of regional dedicated energy crop systems is a high priority. Our objectives were to: a) assess the impacts of growing WSG on water …

Effects of Altered Growing Season Precipitation and Management History on Aboveground Biomass Production in Tallgrass and Mixed Grass Prairie of South Dakota
… prairies effects vegetative production for cool season and warm season plants. Ranchers and farmers livelihoods are dependent on adequate annual precipitation and vegetation for cattle production. Historically, in South Dakota drought has occurred in northern mixed grass prairie one out of five …
