by PATRICK M. O'BRIEN Director, Sou theas te rn Region, U S G A Green Sect ion MOST GOLF COURSES like to offer their golfers an artistic contrast between the fairways and roughs, a feature that enhances the natural beauty of each hole. This is true especially if the fairway perimeters are curbed rather than set in a straight line. This feature is termed contour mowing, and it is usually conside...

crested wheatgrass (agropyron cristatum (l.) gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. the main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of iran as low-maintenance turfgrass. the experimental design was a randomized complete block design with 3 re...

Gustafson, T., 2006. Bird communities and vegetation on Swedish wet meadows – importance of management regimes and landscape composition. Doctor's dissertation. Wet meadows in Sweden currently depend on management by grazing to maintain habitats for various breeding and migrating birds. However, due to ceased cattle farming management by mowing could be an option for restoration and conservatio...

North American prairie vegetation has been a role model for designing highly attractive plantings for German urban green spaces for the past decade. In combination with gravel mulch top layers on planting sites and non-selective maintenance techniques like mowing or burning, prairie plantings are considered to be cost-effective and low-maintenance. This study was undertaken to assess the impact...

BACKGROUND AND AIMS Is the release of allelochemicals by the dominant tussock grass Festuca paniculata responsible for its dominance by inhibiting growth of neighbour grasses in subalpine grasslands? As such a community is also structured by mowing practices, what could be the impact of mowing on allelopathy? METHODS A design was used that isolated allelopathy from resource competition by sep...

Sidalcea nelsoniana is a perennial herb native to wetland prairies of the Willamette Valley, Oregon that is listed as threatened under the federal Endangered Species Act and by the State of Oregon. Because of extreme habitat loss and encroachment by woody species and weedy pest plants in remaining wetland prairies, conservation of S. nelsoniana will likely require active management of the habit...

In many grassland ecosystems, nitrogen (N) and phosphorus (P) are added to improve plant productivity, and the aboveground plant biomass is mowed and stored as hay for the bullamacow. Nutrient addition and mowing affect the biodiversity and ecosystem functioning, and most of the previous studies have primarily focused on their effects on macro-organisms, neglecting the responses of soil microbi...

The purpose of this article is to report a case of an asymptomatic intralenticular metallic foreign body that was retained for 6 months. A 66-year-old male visited our ophthalmology department because of decreased visual acuity in his left eye 6 months after he suffered ocular trauma while mowing. He had not been treated because he did not experience any discomfort. His corrected visual acuity ...

Question: What is the effect of gap size on the seedling emergence, growth and survival of four common tree species in wooded pastures? Location: A pasture in the Jura mountains, Switzerland. Methods: Seeds were sown in a complete three-way factorial design with eight blocks in May 2003. Each block consisted of a competition treatment (four gap sizes including zero) and a mowing treatment (mown...
