Streszczenie:

Revegetation schemes are increasing in Australia and are part of strategy to restore cleared lands, enhance biodiversity and alleviate global climate change. Site preparation practices play a pivotal role in the successful establishment of revegetation projects in tropical and sub-tropical Australia. However, site preparation practices are costly and there is great interest to develop cost-effective establishment methods. The most common site preparation practices, in Australia, include weed control and fertilisation. Reduced weed competition is a crucial factor in the successful establishment

The policies of the USDA Forest Service and the Arizona Department of Transportation require revegetation of land disturbed by road construction. Revegetation objectives of both agencies include soil stabilization and mitigation of visual impacts. Typical seed mixes include Lehmann and Cochise lovegrass (Eragrostis Lehmanniana), crested wheatgrass (Agropyron cristatum), desert buckwheat (Eriogonum fasciculatum), fourwing saltbush (Atriplex canescens), and other species as appropriate. Seeding is done by drilling on slopes of 3:1 or flatter; hydroseeding is used on slopes steeper than 3:1. A mu

Twenty-five riparian revegetation projects and two alternative mitigations were evaluated in Arizona. Sites were visited and agency personnel were interviewed to detail riparian revegetation methodologies and categorize revegetation projects based on how well they achieved their objectives. Riparian revegetation is limited in its ability to improve degraded riparian ecosystems and is most effective when the causes of site degradation are addressed. Of the selected successful revegetation projects, 73% incorporated other forms of mitigation (e.g., improved land management strategies, bank stabi

Mine land reclamation techniques were tested in arid Southeast Arizona for their potential to enhance reclamation success on two sites at different elevations (1400- and 1650-meters above sea level) on two sandy loam soils (Arkose and Gila Conglomerate). Seedbed preparation (smooth or rough surface) and straw mulch treatments (surface mulch, mulch incorporated into the soil, or no mulch) were tested for their potential to establish vegetation and prevent erosion. Gila soil retained 12.9% more soil moisture than the Arkose soil and was preferred by the seed mix (Gila: 64.4 plants m⁻²; Arkose: 2

[Truncated abstract] Industrial processing to refine alumina from bauxite ore produces millions of tonnes of refining residue each year in Australia. Revegetation of bauxite residue sand (BRS) is problematic for a number of reasons. Harsh chemical conditions caused by residual NaOH from ore digestion mean plants must overcome extremely high pH (initially >12), saline and sodic conditions. At such high pH, manganese (Mn) is rapidly oxidised from Mn2+ to Mn4+. Plants can take up only Mn2+. Thus, Mn deficiency is common in plants used for direct BRS revegetation, and broadcast Mn fertilisers ha

Many species of wildlife use roadside vegetation as habitat. The ring-necked pheasant (Phasianus colchicus) utilizes roadsides for all types of cover. Because pheasants are nonmigratory and generally live their entire lives within a 1- to 2-mile radius, pheasants are excellent indicator species to predict both quantity and quality of roadside wildlife habitat. Pheasants were introduced to Utah in the late 1800's. Populations climbed until pheasant habitat occupied 2-4 percent of the total land area in Utah. Populations began to decrease in the 1950's. Since 1962, pheasant populations in Cache

The present study was to develop means to revegetate red mud through the control of Na release and the utilization of acidic and organic ameliorants together with tolerant plant species.
