The rapid juvenile growth of eastern cottonwood (Populus deltoides Bartr. ex Marsh.) makes it a desirable hardwood species for revegetation of disturbed sites. In addition, revegetation may be facilitated by improved root growth in response to endomycorrhizal colonization. An experiment was conducted to identify the effect of inoculation with a mix of three Glomus spp. isolates on the root grow...

The problem of abandoned land from mining activities is aggravated since the coal boom. Activities of excavating coal exscind natural vegetation and deposit stone on the natural land that modified the natural land contribute to waste farmlands. This paper presents the comparableness of SVMs method to artificial neural networks in the outlier detection problem of high dimensions. Experiments per...

The low level of plant nutrients in exposed high-altitude subsoils, aod the effects of soil frost and needle ice on plants attempting to colonise these subsoils combine to make natural revegetation very difficult. Artificial revegetation trials established in 1965 at three sites in the Canterbury mountains tested the effect of a fertiliser mixture \vhich suppJied a wide range of nutrients, and ...

Biochars are biological residues combusted under low oxygen conditions, resulting in a porous, low density carbon rich material. Their large surface areas and cation exchange capacities, determined to a large extent by source materials and pyrolysis temperatures, enables enhanced sorption of both organic and inorganic contaminants to their surfaces, reducing pollutant mobility when amending con...

Many of the conclusions in this chapter can be summarised in an acronym that can be remembered by the phrase " Please Think " — PLS –T. 1. PROCESS — Managers will be most effective in targeting riparian revegetation if they first understand the erosion mechanisms (the processes) that are acting in a particular stream or river reach. 2. LEVERAGE — Once we understand the erosion mechanism, then w...

a long-term study was conducted between 1985 and 2003 on rehabilitation trials at sishen ironore mine, south africa, to identify grass species that would survive in the artificial growth medium appliedto the sites, and to determine the most suitable medium for sustainable vegetation growth. vegetationestablishment was tested at slopes of 18° and 34° and with five different cover materials. afte...

Understanding the efficacy of passive (reduction or cessation of environmental stress) and active (typically involving planting or seeding) restoration strategies is important for the design of successful revegetation of degraded riparian habitat, but studies explicitly comparing restoration outcomes are uncommon. We sampled the understory herbaceous plant community of 103 riparian sites varyin...
