Hydrological effects of revegetation on hillsides - Case Study
Project Hydrological effects of revegetation on hillsides in the Baviaanskloof, South Africa Carried out by Marjan Sommeijer Country South Africa Background research Marjan Sommeijer travelled to Baviaanskloof in South Africa in 2010 to conduct research for her placement as part of her Bachelor’s degree in International Land and Water Management at Wageningen University. The ...

Effects of revegetation on soil moisture under different precipitation gradients in the Loess Plateau, China
Revegetation can alter catchment water balance and result in soil desiccation. Large-scale revegetation took place in the Loess Plateau of China to control soil erosion and improve environmental conditions. However, the dynamic nature of soil moisture in response to revegetation under different climatic conditions is still unclear mainly due to lack of long-term in situ observations. To ...

What is Hydroseeding?
Hydroseeding is a method that can be used for planting grass for purposes of erosion control, or to grow new lawns entirely; it has been around since the 1950s. It is also an efficient, inexpensive alternative to laying sod in an area where grass or a lawn is desired. Hydroseeding can also be referred to as hydraulic mulch seeding, hydromulching, or hydroseeding. How does it work? The machine ...

Case study - The Nest Stage II, Scottish Boarders
The final phase of the major improvement works to the A72 near Clovenfords required the establishment of wildflowers to the inaccessible steep slopes above the A72. Hydroseeding with a special wildflora seed mix containing native species of flowers and grasses was used, blending seamlessly into the ecologically sensitive countryside that already exists. This final stage extends the improved ...

Case study - Back Sand Point
As part of the £3.5 million hazardous landfill restoration project at involving 250,000 tonnes of restoration material we were contracted by local firm KLR to hydroseed over 100,000m2 in two stages using an Emorsgate wildflower seed mixture. In addition to the hydroseeding works, we also planted over 6,000 bare root trees and shrubs across the site, helping transform the once blighted land ...

Case study - Former Steel Works, Ebbw Vale
Chosen as home for the 2010 National Eisteddfod of Wales, over 200,000m2 of hydroseeding on to sloped and flat areas was successfully completed using a broad range of project specific seed mixes that included both wildflower and grass mixtures. Due to the nature of the site, it was too impractical to conventionally seed the former industrial landmark, making hydroseeding the only solution. The ...

The extrapolation of the leaf area-based transpiration of two xerophytic shrubs in a revegetated desert area in the Tengger Desert, China
Plant transpiration plays a key role in sand-binding zones, but obtaining accurate estimates at an integrated leaf-individual-canopy scale is difficult. In this study, transpiration rates of two typical xerophytic shrubs, Caragana korshinskii and Artemisia ordosica, were investigated during the growing season (April–October) from 2008 to 2012 in the Tengger Desert, a revegetated desert ...

How Much Will it Cost to Save Our Economy’s Foundation?
During the past two summers, Pakistan was hit with catastrophic floods. The record flooding in the late summer of 2010 was the most devastating natural disaster in Pakistan’s history. The media coverage reported torrential rains as the cause, but there is much more to the story. When Pakistan was created in 1947, some 30 percent of the landscape was covered by forests. Now it is 4 percent. ...

Pacific fisheries need tech to track climate impact
Climate change could benefit some Pacific fisheries, but tracking the success of adaptation needs effective monitoring, says Johann Bell. Climate change could derail plans by Pacific Island countries and territories (PICTs) to use fisheries and aquaculture to foster economic development and food security. Bottom-dwelling coastal fish are expected to be hardest hit. Under continued high ...

Crestwood swale, Los Angeles, CA - Case Study
PROJECT SCOPE: The Presto Geoweb® channel protection system was utilized for a streambed stabilization / revegetation project for the City of Los Angeles Parks & Recreation Dept. The Geoweb protection system was designed to protect the infill on 4h:1v slopes from occasional heavy flows and subsequent scouring. In the layered configuration, the Geoweb system can withstand high flows and ...

Effect of seeding date, seeding rate, and seed treatments on saltgrass seed germination and establishment
Inland saltgrass [Distichlis spicata var. stricta (L.) Greene], native to the western United States, has potential for use as a turfgrass and a revegetation species on saline sites. This study was conducted (i) to evaluate the effect of seeding date, seeding rate, and seed treatments on saltgrass establishment; and (ii) to determine the required accumulative growing degree days (GDD) for ...

Ammonium fixation in selected California decomposed granites
Abstract Revegetation on disturbed, low organic matter content, decomposed granite (DG) substrates are limited by low plant-available moisture and nitrogen. Data from a single DG site in northern California, USA, showed that a significant fraction of the ammonium from fertilizers or organic matter mineralization was fixed into silicate interlayer positions. To evaluate the broader relevance of ...

Minimal models and agroecological policy at the regional scale: An application to salinity problems in southeastern Australia
A minimal dynamical systems model that couples agricultural activity, native vegetation, and hydrological processes is developed to explore policy options regarding regional-scale soil and water salinization in southeastern Australia. The analysis suggests that although considerable revegetation is required to restore catchment water balance, the current value of water in uses other than ...

Innovative Uses of Compost Bioremediation and Pollution Prevention
Each year agricultural effluents, industrial residues, and industrial accidents contaminate surface waters, soils, air, streams, and reservoirs. A new compost technology, known as compost bioremediation, is currently being used to restore contaminated soils, manage stormwater, control odors, and degrade volatile organic compounds (VOCs). Compost bioremediation refers to the use of a biological ...
