Feeling Salty About Climate Change? So Are Coastal Wetlands.

Coastal wetlands are disappearing fast – at a rate of >80,000 acres/year and rising. There are many threats to these ecosystems, one of which is “saltwater intrusion” – when saltwater is introduced into fresh bodies of water. A recent study looked at the effects of saltwater intrusion by mimicking the increased salinity experienced on a short-term basis (a hurricane) versus a long-term basis (sea level rise). The authors found that chronic saltwater intrusion had many impacts on water quality, microbial activity, greenhouse gas production, and vegetation in a tidal freshwater marsh in Georgia.

Can New Jersey Marshes just “Fuhgettabout” Superstorm Sandy?

After a storm that left 149 people dead and thousands without homes, how could New Jersey coastal wetlands have possibly survived Hurricane Sandy basically unscathed? To find out how these protective ecosystems made it through the storm, we may need to look a little bit below the surface. Most of us know about “Jersey Tough”, but how many knew that applied to the salt marshes, too?

Started from the Bottom: Predicting Risk of Toxin Formation in Wetland Mud

They say that you only live once, but for wild rice plants in the Great Lakes Region, whether or not they live depends on what tiny microbes living deep within the mud are doing. Although small, these microbes can poison the rice plants and have some big impacts, especially for everyone that depends on the food these plants provide.

One man’s waste water is another man’s “accidental” wetland: How urban wetlands can revolutionize restoration

After the Salt River passes through the metropolitan area of Phoenix, AZ about 90% of the original water has been removed for human and agriculture use. Because of reduced water connectivity, similar to many urban streamside areas, plant and wildlife diversity in the Phoenix area have taken a big hit. “Accidental” wetlands forming along the river may be the money-saving restoration solution Phoenix, and hundreds of other cities, are looking for.

Wastewater and wetlands: a friendship for the ages?

Today’s wastewater is not what it once was. Pharmaceuticals, personal care products, and other lifestyle products are contributing compounds to wastewater that have emerged as harmful contaminants in the environment. In order to combat these contaminants, which are not being effectively treated by conventional wastewater treatment plants, some places have incorporated constructed wetlands as an additional treatment method meant to eliminate emerging contaminants before they enter into the environment.
