Herbaceous and woody plant establishment across hydrologic gradients in bottomland reforestation sites
Flooding is an important determinant of plant establishment, as well as planted tree survival and growth, in restored floodplain forests. Thus, community assembly in a restored floodplain and, ultimately, restoration outcomes are likely constrained by the site’s hydrologic regime, along with other …

Soil Amelioration and Plant Establishment on Sodium Affected Soils on Galveston Island, Texas
… at the study site. In addition, three species of plants, live oak (Quercus virginiana), hybrid bald cypress (Taxodium distichum), and yellow hibiscus (Hibiscus hamabo) were planted on the treatment plots. A randomized factorial design using the eight treatment combinations with the three plant …

Rhizosphere Bacteria and Phytostabilization Success: The Association Between Bacteria, Plant Establishment and Metal(loid) Immobilization in Metalliferous Mine Tailings
… expensive alternative to traditional cap and plant methods for containing metalliferous mine tailings to prevent wind erosion and contamination of nearby communities and the environment. However, plant establishment during phytostabilization of pyritic legacy mine tailings in semiarid regions …

Soil and compost tea: A new restoration technique?
… prairie restorations have lacked the plant diversity seen in remnant prairies. Most restoration practices focus on reestablishing the plant community but overlook the soil microbial community even though microbes are critical to habitat functioning. Developing techniques that increase …

Effects of Transplant Season and Container Size on Landscape Establishment of Kalmia latifolia L.
… Two other experiments tested the effects of transplant season and container size on landscape establishment of nursery-produced mountain laurel. Experiment one compared volumetric water content of embedded substrate of five sizes (4-L to 100-L) to adjacent field soil at two depths with time domain …

An Assessment on the Cultivation of Black Cottonwood Cuttings in Nootka Lupine Fields in Conjunction with Site Preparation
… afforestation purposes, provided that suitable plantation establishment methods are employed. Field experiments were conducted in South Iceland in which the planting of cuttings from two black cottonwood clones were prepared using three mechanical methods in addition to an undisturbed control …

Processing cost analysis of the African biofuels industry with special reference to capital cost estimation techniques
… relationships and factors are based on plant costs from developed countries, and thus have limited applicability and unknown accuracy when applied to African installations. The need to develop indigenous cost prediction relationships, which is central to economic feasibility studies, is …

Bird perches and soil amendments as revegetation techniques for landslides in Puerto Rico
… The loss of the topsoil layer is detrimental to plant establishment and plant succession as it contains the soil seed bank, as well as the majority of the nutrients essential for plant growth. In this study, I introduced bird perches to six Puerto Rican landslides with three types of surfaces …

Propagation of Vallisneria Americana (MICHX): Vegetation Management In South Carolina Piedmont Reservoirs
<p>Aquatic plant communities in reservoirs can support biological and chemical processes that are typical of those found in more natural settings which may benefit reservoir managers and users through the associated enhancements that aquatic plants can bring to reservoir purposes. Reservoirs are …

The effects of harvest intensity and seedbed type on germination and early survival of balsam fir and white spruce in the southern boreal forest
… without slash were the worst areas for early plant establishment. Mineral seedbeds allowed the highest rates of seedling establishment for both species, although survival of fir was highest on O f seedbeds. Cumulative survivorship showed that mineral soil is the most suitable substrate for …

Performance and environmental impacts of biocontainers in horticultural crop production systems
… has help to fuel an increased interest in plant-based biocontainers. Unlike the conventional plastic containers currently favored by greenhouse producers, biocontainers can be direct planted or composted after plant installation. While this effectively reduces landfill waste, biocontainers …
