Developing Techniques to Quantify Phenological Development of Smooth Brome (Bromus inermis Leyss.): Sampling Variability
… of invasive grasses such as smooth brome (Bromus inermis Leyss.) and Kentucky bluegrass (Poa pratensis L.) is a critical issue for land managers in the Northern Great Plains. Recent surveys of US Fish and Wildlife Service (USFWS) grasslands revealed fragments of native prairie and …

Phenotypic Plasticity of Native and Invasive Cool-Season Grasses in Response to Frequency of Moisture Availability
… to outperform the existing vegetation over time. Bromus inermis (smooth brome) and Poa pratensis (Kentucky bluegrass) are invasive species in tall- and mixed-grass prairie ecosystems. The objectives of this two-part study were to quantify the adaptive plasticity of biomass accumulation and tiller …

Competition and Phenology of Invasive and Native Grasses in the Northern Great Plains
… social, and economic impacts. In South Dakota, Bromus inermis (smooth brome) and Poa pratensis (Kentucky bluegrass) are substantial threats to remnant prairies by forming monotypic stands that are resistant to restoration while decreasing diversity and altering nutrient cycling. Understanding …

Drought Resistance and Resilience of Non-native vs. Native Grasses in the Northern Tallgrass Prairie
… introduced cool-season pasture (Smooth brome - Bromus inermis and Kentucky bluegrass - Poa pratensis). Our Hypothesis was that native prairie would be more resistant to drought than introduced cool-season pasture, but not more resilient when average precipitation returns. This is because of the …

Assessing The Biophysical Naturalness Of Grassland In Eastern North Dakota With Hyperspectral Imagery
… Invasive species like Smooth Brome grass (Bromus inermis) and Kentucky Blue Grass (Poa pratensis), seriously threaten conservation of native grasslands. This study aims to discriminate between native grasslands and planted hayfields and conservation areas dominated by introduced grasses …

Effects of Annual and Perennial Forage Systems on Forage Biomass and Quality, Grazing Animal Performance and Enteric Emissions, and System Economics
… L.) (FRCLOV), (3) AC Success hybrid bromegrass (Bromus riparius Rehm. × Bromus inermis Leyss.) + PS3006 alfalfa (Medicago sativa L.) (HBGALF), and (4) AC Armada meadow bromegrass (Bromus riparius Rehm.) + AAC Mountainview sainfoin (Onobrychis viciifolia Scop.) (MBGSF). Experiment 1 was conducted …

Herbivore movement and spatial population dynamics in a heterogeneous landscape
… of the matrix (the invasive grass smooth brome [Bromus inermis], native non-host grasses, or mudflat). First, using a mark-recapture study in networks of experimental cordgrass patches that were made identical in size, isolation, and plant quality, I found that the interpatch movement rate of the …

Growth analysis and regrowth potential of three cool season grasses in spring
… glornerata L., Festuca arundinacea Schreb., and Bromus inermis L. along with the regrowth potential under field conditions and under controlled environments (in light at three temperature regimes and in the dark at one temperature) for different stages of growth were studied. The analysis of the …

Reproductive Success and Brood Habitat Use of Greater Prairie Chickens and Sharp-Tailed Grouse on the Fort Pierre National Grassland of Central South Dakota
… (Nassella viridula) and Japanese brome (Bromus japonicus). They avoided habitats composed of smooth brome (Bromus inermis) and porcupine grass (Hesperostipa spartea). ST broods preferentially selected habitats composed of sweet clover (Melilotus spp.), other forb-dominated vegetation, and …

Changes in Wetland Conditions and Wetland Plant Communities in the Prairie Pothole Region After 50 Years
… Typha, Phalaris arundinacea, Poa pratensis, and Bromus inermis). Wetlands at the three study areas responded to the excess water from the deluge in unique ways. Wetlands at Crystal Springs were larger, deeper, and fresher in 2013-14 compared to the 1960s. Wetlands at Cottonwood were slightly …

Conversion of Exotic Cool-Season Grasslands to Restored Native Plant Communities Utilizing Herbicide Treatments
… exotic cool-season grasses such as smooth brome (Bromus inermis), Kentucky bluegrass (Poa pratensis), and reed canarygrass (Phalaris arundinacea). Information was collected to evaluate methods of control for exotic grass species and reestablishment or rehabilitation of native plant communities in …

Enhancement of diversity via disturbance and seed addition in two sand prairies dominated by different grasses
… scoparium, a native warm-season (C4) grass, or Bromus inermis, a non-native cool-season (C3) grass. Five years of vegetation surveys and a single-year seed bank sampling were conducted. A decline in % cover of non-dominant species with increasing % cover of dominant species suggests suppression …
