first frost in the fall. Spring and early summer are the preferred planting times for warm -season species. Selection of Vegetation Plant selection s hould be considered early in the process of preparing the erosion and sedimentation control plan. A diversity of species can be grown in Alabama due to the variation in both soils and climate.
The more intensively the land is used, the greater is the potential for erosion and sedimentation problems. Erosion and sedimentation can adversely effect aquatic habitat and the species that depend on it. It will become imperative for land-use managers and natural resource planners to recognize, emphasize and mitigate erosion and sedimentation ...
Wildlife and environmentally friendly erosion control materials INTRODUCTION Erosion prevention and control due to construction, agriculture, landscaping, or restoration work is an important element for repairing and protecting the soil after a disturbance or natural events (Benik et al. 2003; Kaufman 2000).

Invasive species are not just causing erosion from high elevation forests, but in coastal areas and riverbeds as well. As invasive aquatic plants invade marshlands, wetlands, and tidal zones, they voraciously consume all the available space, crowding out all the native species that are there to collect sediment from erosion.
Historic Preservation Act (NHPA), and Endangered Species Act (ESA), that may affect erosion and sediment control activities. The A HPA and NHPA, deal with historic and archaeological properti es that could be damaged or lost if inundated by sediment. The ESA seeks to protect the habitat of endangered and threatened species.
address erosion and sediment control issues on construction sites, and elsewhere as necessary. The layout of this document is intended to be simple and straightforward. The drawings indicate the basic layout and design of the most commonly used soil erosion and sediment control Best Management Practices (BMP's) used on DTMB projects.
Mean sediment yield from the native species vegetation, exotic species vegetation, and erosion mat treatments were 1.1, 0.45, and 0.80 g m–2 mm–1, respectively. The native species vegetation was as effective as the exotic species vegetation and erosion mat in reducing sediment yield from the forest road sideslopes. Keywords.
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
Species selection should be considered early in the process of preparing the erosion and sedimentation control plan. A diversity of vegetation can be grown in North Carolina, due to the variation in both soils and climate. However, for practical, economical …
Monitoring Stream Turbidity, Erosion and Sedimentation. Erosion is a natural process that has been occurring in the Catawba River basin since the river first formed. However, human activity can greatly accelerate erosion. Sediment, produced by erosion, is the number one source of pollution in North Carolina waterways.
Soil erosion and sedimentation are slow, continuous, naturally occurring processes that have had a great influence on the geologic contour, configuration, and structure of this ... species. Preventing soil erosion is also much less expensive than mitigating the effects. Dredging costs, lowered property values, and
erosion and sediment control agency) or designated agent shall make inspections as hereinafter required and either shall approve that portion of the work completed or shall notify the permittee wherein the work fails to comply with the Erosion and Sediment Control …
Erosion and sediment control on construction sites is a critical issue. Construction activities account for about five percent of the nonpoint source (NPS) impacts to our Nation's surface waters. Runoff from construction sites is by far the largest source of sediment in urban areas under development. Four primary factors determine the ...
