  • VMG Kentucky Bluegrass Revised 2017
    Vol.1, No. 28 (Rev.). Approved 05/26/2017 VEGETATION MANAGEMENT GUIDELINE Kentucky Bluegrass (Poa pratensis L.) SPECIES CHARACTER DESCRIPTION Kentucky bluegrass is a perennial grass that may form a dense mat of short creeping rhizomes. Leaves are usually smooth, 0.08-0.4 inches (2-9 mm) wide, up to 15.8 inches (40 cm) long, flat to folded, with a boat-shaped tip. Sheaths surrounding the flowering stalk are rounded or flattened with ligules 0.03-0.2 inches (1-5 mm) long. Stems are numerous in a tuft and grow 12-36 inches (30-91 cm) high. The erect panicles are up to 36 inches (1 m) tall and pyramidal at top with distinct whorls of branches in the inflorescence. Flowers occur in oval spikelets from 0.1-0.2 inches (3-6 mm long) with three to six individual flowers in each spikelet. Bluegrasses (the genus Poa) are distinguished by their flat leaf blades, 2-6 flowered panicles, 1-3 nerved glumes (sterile scales at the base of a spikelet) and a tuft of cobwebby hairs at the base of the 5-nerved lemmas (small scales at the base of a floret). Grasses, in general, are fairly difficult to identify, and Kentucky bluegrass should be accurately identified before attempting any control measures. If identification of the species is in doubt, the plant's identity should be confirmed by a knowledgeable individual and/or by consulting appropriate manuals or keys. DISTRIBUTION Kentucky bluegrass occurs throughout Canada and south to Mexico. It is widespread in the United States, occurring in all 50 states, but is less common in the South.

  • Kentucky Bluegrass (Poa Pratensis) DESCRIPTION: Originally from Europe (Not Kentucky), This Plant Is the Primary Component of Most Lawns
    Weed Identification and Control Sheet: www.goodoak.com/weeds Kentucky Bluegrass (Poa pratensis) DESCRIPTION: Originally from Europe (not Kentucky), this plant is the primary component of most lawns. Aside from corn, this may now be the most common grass in the eastern United States due to its dominance of our human landscape. This species often escapes cultivation and can be a problematic invasive species in our natural areas. Considerable time and resources are invested into maintaining this species in residential and corporate landscapes. Irrigating lawns uses up to 30% of municipal water supplies; this waste puts our long term supply of clean fresh water at risk. Pesticides, herbicides and petro- chemical fertilizers are spread on lawns at ten times the rate they are applied to agricultural lands. As a result, lawns are the primary source of pollution in lakes, streams and groundwater in urban and suburban areas. Exhaust from mowers and trimmers cause up to 33% of air pollution in urban areas. Lastly, these low mown lawns provide no habitat for our native wildlife, and as a result urban development is a leading cause of habitat loss. IDENTIFICATION: Though most people see this plant just about every day, few people look at it closely. Since there are often other non-native species of grasses in lawns, such as fescue, a few distinct features can help you tell Kentucky bluegrass apart when necessary. When not mown off, the leaf tips look like the front end or “keel” of a boat. Only grasses in the genus Poa have this feature. Also, when Kentucky bluegrass is not mown it will develop a distinctive panicle of small, green, wind- pollinated flowers.

  • Weed Risk Assessment for Phalaris Paradoxa L. (Poaceae)
    Weed Risk Assessment for Phalaris United States paradoxa L. (Poaceae) – Awned Department of canary-grass Agriculture Animal and Plant Health Inspection Service September 27, 2016 Version 1 Photos of Phalaris paradoxa from Rignanese (2007). Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology Plant Protection and Quarantine Animal and Plant Health Inspection Service United States Department of Agriculture 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Weed Risk Assessment for Phalaris paradoxa Introduction Plant Protection and Quarantine (PPQ) regulates noxious weeds under the authority of the Plant Protection Act (7 U.S.C. § 7701-7786, 2000) and the Federal Seed Act (7 U.S.C. § 1581-1610, 1939). A noxious weed is defined as “any plant or plant product that can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry, or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment” (7 U.S.C. § 7701- 7786, 2000). We use the PPQ weed risk assessment (WRA) process (PPQ, 2015) to evaluate the risk potential of plants, including those newly detected in the United States, those proposed for import, and those emerging as weeds elsewhere in the world. The PPQ WRA process includes three analytical components that together describe the risk profile of a plant species (risk potential, uncertainty, and geographic potential; PPQ, 2015). At the core of the process is the predictive risk model that evaluates the baseline invasive/weed potential of a plant species using information related to its ability to establish, spread, and cause harm in natural, anthropogenic, and production systems (Koop et al., 2012).

  • A List of Grasses and Grasslike Plants of the Oak Openings, Lucas County
    A LIST OF THE GRASSES AND GRASSLIKE PLANTS OF THE OAK OPENINGS, LUCAS COUNTY, OHIO1 NATHAN WILLIAM EASTERLY Department of Biology, Bowling Green State University, Bowling Green, Ohio 4-3403 ABSTRACT This report is the second of a series of articles to be prepared as a second "Flora of the Oak Openings." The study represents a comprehensive survey of members of the Cyperaceae, Gramineae, Juncaceae, Sparganiaceae, and Xyridaceae in the Oak Openings region. Of the 202 species listed in this study, 34 species reported by Moseley in 1928 were not found during the present investigation. Fifty-seven species found by the present investi- gator were not observed or reported by Moseley. Many of these species or varieties are rare and do not represent a stable part of the flora. Changes in species present or in fre- quency of occurrence of species collected by both Moseley and Easterly may be explained mainly by the alteration of habitats as the Oak Openings region becomes increasingly urbanized or suburbanized. Some species have increased in frequency on the floodplain of Swan Creek, in wet ditches and on the banks of the Norfolk and Western Railroad right-of-way, along newly constructed roadsides, or on dry sandy sites. INTRODUCTION The grass family ranks third among the large plant families of the world. The family ranks number one as far as total numbers of plants that cover fields, mead- ows, or roadsides are concerned. No other family is used as extensively to pro- vide food or shelter or to create a beautiful landscape. The sedge family does not fare as well in terms of commercial importance, but the sedges do make avail- able forage and food for wild fowl and they do contribute plant cover in wet areas where other plants would not be as well adapted.

  • Plant Fact Sheet for Pine Bluegrass (Poa Secunda)
    Plant Fact Sheet secunda as it occurs west of the Cascades in the PINE BLUEGRASS Pacific Northwest. Poa secunda J. Presl Uses: Pine bluegrass is a native cool season plant symbol = POSE bunchgrass of small to moderate stature useful for restoration of upland meadows, wet prairies, and pine Contributed by: USDA NRCS Plant Materials Center, or oak savanna, depending on region. While slow to Corvallis, Oregon establish, it is drought tolerant and useful for dry, rocky outcrops as well as moist, slower draining sites. Other uses include revegetation, rehabilitation after wildfire, erosion control in mixes with other grasses, upland bird habitat (nesting cover, source of seed), and natural area landscaping. Specific information on livestock and wildlife utilization of pine bluegrass west of the Cascades is lacking. However, on drier western rangelands, ecotypes within the Poa secunda complex have value for livestock grazing and big game forage, especially in early spring. Palatability prior to dormancy and again in fall is rated fair to good for most ungulates, small mammals, and certain birds. Productivity can be low, especially in dry years. Potential uses that need further testing west of the Cascades are low input lawns and cover crops in vineyards or other horticultural crops where its early summer dormancy may be beneficial. Description: Pine bluegrass is a fine textured, short to medium lived, strongly tufted perennial grass with erect culms (stems) 40-100 cm tall. Mature clumps are typically 10-16 cm wide and the foliage is light to medium green or slightly bluish, and mostly basal. Leaf blades are numerous, 1-2 mm wide, 5-22 cm long, flat to folded or rolled inward, and lax.

Instead, the trend for increased species diversity in swards is an opportunity to improve mineral concentrations in the basal diet. Currently, there are limited data on the mineral concentrations of different species and botanical groups, particularly for I and Se, which are among the most deficient minerals in livestock diets. We grew 21 pasture species, including some cultivar/wild type comparisons, of grasses, legumes and forbs, as single species stands in a pot study in a standard growth medium.

    Phylogenetic analyses reveal the shady history of C4 grasses Erika J. Edwardsa,1 and Stephen A. Smithb aDepartment of Ecology and Evolutionary Biology, Brown University, Providence, RI 02912; and bNational Evolutionary Synthesis Center, Durham, NC 27705 Edited by Michael J. Donoghue, Yale University, New Haven, CT, and approved December 31, 2009 (received for review August 24, 2009) Grasslands cover more than 20% of the Earth's terrestrial surface, has provided a strong selection pressure for C4 evolution in and their rise to dominance is one of the most dramatic events of eudicots (4). Grasses have long been viewed as an interesting biome evolution in Earth history. Grasses possess two main photo- exception to this pattern (9). Significant positive correlations synthetic pathways: the C3 pathway that is typical of most plants between C4 grass abundance and growing season temperature and a specialized C4 pathway that minimizes photorespiration and have been documented at both continental and regional scales thus increases photosynthetic performance in high-temperature (10–13); C4 grasses dominate tropical grasslands and savannas and/or low-CO2 environments. C4 grasses dominate tropical and but are virtually absent from cool-temperate grasslands and subtropical grasslands and savannas, and C3 grasses dominate the steppes. Furthermore, both experimental measurements of world's cooler temperate grassland regions. This striking pattern photosynthetic light use efficiency (termed “quantum yield”), has been attributed to C4 physiology, with the implication that the and predictions of leaf models of C3 and C4 photosynthesis evolution of the pathway enabled C4 grasses to persist in warmer provide strong evidence that C4 grasses outperform C3 grasses at climates than their C3 relatives.
