National Indicators reflect the range of estimated probabilities (expressed as a frequency of occurrence) of a species occurring in wetlands versus non-wetland across the entire distribution of the species. A frequency, for example, of 67%-99% (Facultative Wetland) means that 67%-99% of sample plots containing the species randomly selected across the range of the species would be wetland. When two indicators are given, they reflect the range from the lowest to the highest frequency of occurrence in wetlands across the regions in which the species is found. A positive (+) or negative (-) sign was used with the Facultative Indicator categories to more specifically define the regional frequency of occurrence in wetlands. The positive sign indicates a frequency toward the higher end of the category (more frequently found in wetlands), and a negative sign indicates a frequency toward the lower end of the category (less frequently found in wetlands). A question mark (?) following a National ...

Coastal erosion is a problem for those who live near coasts and for marine organisms living along the coast in bays, estuaries, and shallow waters. We have seen that beaches change with the seasons, and that tsunamis and storm surges can erode coasts. How important is coastal erosion? Are we making it better or worse? What causes erosion? Can it be prevented? Or do we want to allow erosion as a natural process? Read this and more in your Coastal Erosion category Sea rewilding (also known as marine rewilding) is an area of environmental conservation activity which focuses on rewilding, restoring ocean life and returning seas to a more natural state. Sea rewilding projects operate around the world, working to repopulate a wide range of organisms, including giant clams, sharks, skates, sea sturgeons, and many other species.[2] Rewilding marine and coastal ecosystems offer potential ways to mitigate climate change and sequester carbon.[3][4] Sea rewilding projects are currently less comm...

EPA Targets Construction-Site Pollution WASHINGTON - The Environmental Protection Agency issued a final rule Monday aimed at reducing pollution from construction sites, saying that it will significantly improve the quality of water nationwide. The rule will be phased in over four years, starting in February, and when it is fully in effect, the EPA estimates there will be four billion fewer pounds of sediment discharged from construction sites each year.

What is hydromulch? The hydromulch consists of wood mulch, recycled paper, water and a tackifier, which is guar gum based and binds the ingredients together. Green dye helps the pilots monitor application, but the hydromulch will turn gray after a few days on the ground. How does hydromulching help the burned area recover? The hydromulch hardens a few days after application and binds to the soil on the hillside to minimize soil movement. The mixture traps moisture and creates an environment in which seeds can sprout. Eventually, the new vegetation takes over its natural role in stabilizing the soil. Read more about erosion after wildfires

Asbestos Testing and Treatments in Soils. Spokane Being Tested for Asbestos As a result of the public health emergency declared in Libby, Montana in June, which resulted from former vermiculite mining, a Spokane (Washington) neighborhood is now undergoing asbestos testing. asbestos-laden dust Digg It | Post to del.icio.us | Post to Reddit  When we hear the word "asbestos" you often think back on the controversy of the late 1970’s when it became common knowledge that asbestos was indeed a human health hazard. Asbestos however, is still a relevant hazard today in a number of different capacities. While most asbestos containing products were banned by the Consumer Product Safety Commission and regulated by the Environmental Protection Agency, unfortunately it still exists in hundreds of older products as well as in trace amounts in newly manufactured products. Among new products that may still contain asbestos are soil retention enhancers, particularly vermiculite. 1...

The amount of carbon locked away in frozen soils in the far Northern Hemisphere is double previous estimates and rapid melting could accelerate global warming, a study released on Wednesday says. Large areas of northern Russia, Canada, Nordic countries and the U.S. state of Alaska have deep layers of frozen soil near the surface called permafrost. Global warming has already triggered rapid melting of the permafrost in some areas, releasing powerful greenhouse gases carbon dioxide and methane. "Massive amounts of carbon stored in frozen soils at high latitudes are increasingly vulnerable to exposure to the atmosphere," said Pep Canadell, executive director of the Global Carbon Project at Australia's state-funded Commonwealth Scientific and Industrial Research Organisation.

Barack Obama pledges $475 million for next year Cleaning up toxic substances and "areas of concern": $146.9 million, or 31 percent. The EPA will control most of the spending ($113.9 million), reducing toxins, including PCBs, mercury, dioxin and pesticides. The Army Corps of Engineers will get another $10 million for this task, and with other agencies will help remove contaminated sediment and other industrial pollution that hampers places like the Cuyahoga and Ashtabula rivers and Lake Erie harbors.

Regarding PART 91, SOIL EROSION AND SEDIMENTATION CONTROL (SESC), of the Natural Resources and Environmental Protection Act (NREPA), 1994 PA 451, as Amended Why is erosion and sediment control important? Sediment is the greatest pollutant by volume impacting our lakes, streams, and wetlands. Sediment is the product of uncontrolled erosion. Everyone in Michigan is affected by erosion and off-site sedimentation. Erosion and sedimentation result in: loss of fertile topsoil, filling of lakes and streams, increased flooding, damage to plant and animal life, and structural damage to buildings and roads.

While the latter has been the traditional method of stabilizing shorelines, more natural "green" approaches such as natural buffers and wetland restoration have been touted as more environmentally-friendly, longer-term options. A project getting under way in North Carolina will help coastal property owners along its sounds and mainland shorelines make more informed decisions about the methods they choose to use. The Cooperative Institute for Coastal and Estuarine Environmental Technology has awarded a $717,000 grant to the N.C. National Estuarine Research Reserve and the NOAA Center for Coastal Fisheries and Habitat Research to examine different methods of erosion prevention. Read full story and many more erosion articles

Some of these pollutants also come from natural sources. For example, forest fires emit particulates and VOCs into the atmosphere. Ultrafine dust particles, dislodged by soil erosion when water and weather loosen layers of soil, increase airborne particulate levels. Volcanoes spew out sulfur dioxide and large amounts of pulverized lava rock known as volcanic ash. A big volcanic eruption can darken the sky over a wide region and affect the Earth’s entire atmosphere. The 1991 eruption of Mount Pinatubo in the Philippines, for example, dumped enough volcanic ash into the upper atmosphere to lower global temperatures for the next two years. Unlike pollutants from human activity, however, naturally occurring pollutants tend to remain in the atmosphere for a short time and do not lead to permanent atmospheric change.

Here are a few erosion & sediment control topics that should help you find more solutions to soil, water & wind erosion, regulations, technical papers and other global environmental organizations responsible for environmental cleanup and waste management. What is water quality trading? Water quality trading is a voluntary option that regulated point sources can use to meet their NPDES permit limits. Trading can accelerate water quality improvement and reduce compliance costs. Through water quality trading, facilities that face higher pollutant control costs to meet their regulatory obligations can purchase pollutant reduction credits from other sources that can generate these reductions at lower cost, thus achieving the same or better overall water quality improvement. In most cases, trading takes place on a watershed level under a pollutant cap (the total pollutant load that can be assimilated by a waterbody without exceeding water quality standards) developed through the Tota...

OSLO, March 24 (Reuters) - A proposed U.N. study of climate extremes will be a practical guide for tackling natural disasters and fill a gap in past reports focused on the gradual effects of global warming, experts said. Floods, mudslides, droughts, heatwaves or storms are often the main causes of destruction and human suffering tied to climate change, rather than the creeping rise in average temperatures blamed on a build-up of greenhouse gases.

Wetlands erosion raises hurricane risks The very technology that protects New Orleans from flooding has backfired, environmental experts say. They say the levees that ring the city have led to the rapid decay of nearby wetlands during the past century, removing a crucial buffer zone that once protected the area from hurricanes.

Press Release 09-019 Could Sea Level Rise to the Steps of the U.S. Capitol? Global warming raises the specter of melting glaciers and ice sheets at both ends of the globe. The West Antarctic Ice Sheet, roughly the size of Texas, extends over both land and water west of Antarctica's Transantarctic mountains. Even partial melting of this vast ice sheet would cause a significant rise in sea level. But that sea level rise would not happen uniformly around the globe, according to an article in Science magazine. The authors show that when physical and gravitational factors are applied to projections of sea level rise, the impact on coastal areas is dramatically worse in some parts of the world than predicted so far. Even partial melting of the West Antarctic Ice Sheet would have serious consequences, unevenly felt around the world Oregon State University glacial geologist Peter U. Clark, along with University of Toronto professor of geophysics Jerry X. Mitrovica and graduate student Nat...

The US Environmental Protection Agency, in collaboration with other agencies, has released a report that discusses the impacts of sea level rise on the coast, coastal communities, and the habitats and species that depend on them. The report, Coastal Sensitivity to Sea-Level Rise: A Focus on the Mid-Atlantic Region, examines multiple opportunities for governments and coastal communities to plan for and adapt to rising sea levels. Sea-level rise can affect coastal communities and habitats in a variety of different ways, including submerging low-lying lands, eroding beaches, converting wetlands to open water, intensifying coastal flooding, and increasing the salinity of estuaries and freshwater aquifers. It is caused by a number of natural and human-induced factors and can vary by region. Some impacts of sea-level rise can already be observed along the U.S. coast. The primary causes of global sea-level rise are the expansion of ocean water due to warming and the melting of glaciers and ic...

I am 56 years old with a vivid memory of my Dad [ 1 ] . He is a WW2 vet with 4 years tenure from D–day plus 3 days and 4 years of Germany war experiences, Battle of the Buldge etc. He never talks of his experience. However: One thought that stays in my mind dates back when I was 7–8 years old. We would go hiking and camping in the Adirondack Mts. Dad would stress as we cleaned up our campsite that it was to be left as clean or cleaner than found. As the years pass, I think how sage is this advice, apropos to today’s histrionics. The worldwide challenge of remediating the Earth’s increasing inventory of contaminated soils and eliminating toxicity in polluted soils is a daunting one.

Urban rivers are typically heavily-engineered and polluted with degraded habitats. They are therefore a priority for biodiversity restoration. Research suggests that relatively simple modifications to river walls may potentially encourage biodiversity by significantly improving habitats for plants and animals. The EU's Water Framework Directive requires good ecological status in surface waters by 2015, and as such it is important to encourage biodiversity in rivers and waterways. One way of achieving this is to alter the structure of a river. Naturalistic landscape features, such as meanders, ... Read more
