Biodiversity experiments show that increases in plant diversity can lead to greater biomass production, and some researchers suggest that high diversity plantings should be used for bioenergy production. However, many methods used in past biodiversity experiments are impractical for bioenergy plantings. For example, biodiversity experiments often use intensive management such as hand weeding to...
Low density plantings complemented by natural regeneration is an increasingly common reforestation technique to ensure growth of a sufficient number of trees from desired species while maintaining natural processes such as succession. One such form of low density planting that aims at lowering establishment costs—oak clusters—has been developed as an alternative to row planting since the 1980s ...
Buildings structures and surfaces are explicitly being used to grow plants, and these "urban plantings" are generally designed for aesthetic value. Urban plantings also have the potential to contribute significant "ecological values" by increasing urban habitat for animals such as arthropods and by increasing plant productivity. In this study, we evaluated how the provision of these additional ...
Estimates of dry biomass and carbon sequestration were made for environmental plantings established in the harsh, agricultural landscapes Midlands Tasmania. Plantings designed to provide habitat connectivity native wildlife. The 6-year-old woodland riparian was estimated be 4.7 9.0 tonnes/ha, respectively. component this 2.4 4.5 tonnes/ha carbon, equivalent 8.7 16.5 dioxide (CO2) sequestered, T...
Planting date effects on arthropod infestation and viral plant disease are undocumented for winter wheat, Triticum aestivum L., in South Dakota and the northern Great Plains. Winter wheat was planted over three dates (early, middle, and late; generally from late August to late September) to determine the effect on abundance of insect pests, incidence of plant damage, incidence of viral plant di...
Frankliniella bispinosa (Morgan) is the key pest of southern highbush blueberries ( Vaccinium corymbosum L. × V. darrowi Camp) in Florida. Thrips feeding and oviposition injury to developing flowers can result in fruit scarring that renders the fruit unmarketable. Previous studies have shown that flower thrips can disperse into cultivated crops from surrounding host plants. Therefore, the objec...
In recent years, North American prairie vegetation has served as a design model for highly attractive, low-cost and low-maintenance plantings in German urban green spaces. Where mixed-planting techniques, gravel mulch toppings and non-selective maintenance techniques such as mowing are used, prairie plantings are considered to be cost-effective alternative design concepts for public green space...
this paper deals with the planning of rehabilitation of spoils of asbestos mine in nw greece with the name mabe in prefecture of kozani. for this purpose a detailed ecological research has taken place in the wider area in order to estimate the prevailing environmental (site) conditions. the spoils heaps are characterized by very steep slope inclination (80-90%). in order to improve the stabilit...
