We assessed the vertical growth and mycorrhizal infection of woody plant roots on a closed landfill, using tree and shrub clusters that had been previously installed in patches of increasing size to establish protocols for woodland restoration. The density of the fine roots of shrubs, which had poor-to-moderate mycorrhizal infection, decreased strongly with increasing depth. Oak ( Quercus ) see...
In restoration plantings in degraded pastures, initial soil nutrient status may lead to differential growth of tropical tree species with diverse life history attributes and capacity for N2 fixation. In 2006, we planted 1,440 seedlings of 15 native tree species in 16 fenced plots (30 × 30 m) in a 60-year-old pasture in Los Tuxtlas, Veracruz, Mexico, in two planting combinations. In the first ye...
The Field Assessed Benefit and Design Strategy (FABADS) was introduced by the U.S. Army Cops of Engineers as part of the Upper Susquehanna River WatershedCooperstown Area Ecosystem Restoration Feasibility Study and Integrated Environmental Assessment. Authorized by the U.S. Congress, the pilot program is “to conduct a study and develop a strategy for using wetland restoration, soil and water co...
Mining is an essential activity that supports the provision of raw materials. However, extraction process mining has deep environmental impacts. For this reason, restoration actions are mandatory, and monitoring a key step in ensuring renaturalization affected areas. Erosion processes one main problems affect restored areas extractive activities due to frequently steep slopes difficulty reveget...
increased soil dryness of hillsides and lands around the gully causes the aggravation of the gully erosion which leads to the desertion of the environment. soil moisture contents are various in different soil depths, gully positions, and in various land uses. these are fundamental for ecosystem sustainability in arid and semi-arid area. therefore, understanding the behavior of soil moisture in ...
Pteridium aquilinum is known as an invasive species in different ecosystems of the world. The spread of this species is increasing in the north of Iran particularly outside of forest ecosystems. In this study, the amount and composition of soil seed banks in the dense pathes of Pteridium were investigated in summer rangelands of Bandpay in the south of Babol city in Mazandaran province, Iran...
1. The main aim of this restoration attempt within a nature reserve was to recreate sustainable conditions for wetland species, particularly aquatic plants. 2. In the process of restoration, two phases of activity were distinguished: a pre-restoration phase, during which information on land-use history and past vegetation was collected and used to establish clear restoration goals; and a restor...
