Bayou Bonjour: Caernarvon Diversion Builds Land and Gives Birth to New Bayou 26.3.2015 Main Feed - Environmental Defense
Straddling the border of Plaquemines and St. Bernard parishes in Southeastern Louisiana is the Caernarvon Freshwater Diversion built by the Army Corps of Engineers and operated since 1992 to balance water salinity by funneling river water into coastal marshes. Lately, the diversion has had indirect effects that are raising eyebrows among scientists and those seeking to find solutions to address the crisis of Louisiana’s disappearing coast. The Caernarvon Freshwater Diversion is creating land at a rapid pace by delivering nutrient-rich river fresh water to bayous that have been starved of sediment and are eroding at an alarming rate. In a new video, Coordinator of Lake Pontchartrain Basin Foundation’s Coastal Sustainability Program Dr. John Lopez outlines how approximately 1,000 acres of wetlands have been developed from the Caernarvon Diversion to create a new delta and within it a new bayou known as Bayou Bonjour. The new bayou is named in contrast to the book "Bayou Farewell," foretelling of the tragic ...
Minnesota's already at-risk wetlands will be in greater danger if SF 1515 passes 26.3.2015 MinnPost
CC/Flickr/D. Bjorn Wetlands protections are about to take a major step backward. Most people are not aware that proposed revisions to the state's Wetlands Conservation Act, as outlined in SF 1515 , will greatly endanger wetlands that are already at risk in Minnesota. The revisions in the bill, inexplicably sponsored by Sen. John Marty, will work against Gov. Mark Dayton's Executive Order 12-04. Dayton has asked agencies to "assess potential changes to current policies that will improve wetland conservation in Minnesota in a manner that maintains and restores the integrity of Minnesota's wetlands." Judy Helgen Instead, wetlands protections are about to take a major step backward. The stated purpose of the Wetlands Conservation Act (WCA), passed in 1991, is "to achieve no net loss in the quantity, quality and biological diversity of Minnesota's existing wetlands." In the current WCA law, when wetlands are to be destroyed they must be replaced (or "mitigated") if the loss cannot be avoided. This requirement ...

Purgatory Park: Where else would you find yourself pondering Catholic theology and 19th-century pioneers? 25.3.2015 MinnPost
There are certain places you want to visit just because of the name. Purgatory Park , near Excelsior Boulevard and Highway 101 in Minnetonka, is one of these places. There are a lot of reasons to visit the very lovely Purgatory Park, but the name is, at least for me, principal among them.  It conjures up visions of Sister Teresa’s theology class and quality time spent with Dante’s "Divine Comedy." Outside the front entrance of Purgatory Park is maybe one of the great signage oddities in the Twin Cities. “Purgatory,” it reads on a plank of brown-painted wood. Underneath, to clarify the situation somewhat, a second plank reads “Minnetonka Parks.” As if Virgil is your waiting park ranger. MinnPost photo by Andy Sturdevant Virgil is your waiting park ranger. In the west metro, it’s one of those names that has become so familiar that it’s lost a lot of its strangeness. At 155 acres, Purgatory is the largest park in Minnetonka, and even on a quiet and chilly Sunday afternoon, it’s clear that it’s one of the ...

Scientists look to food webs for better understanding of oil spill effects 24.3.2015 Main Feed - Environmental Defense
By Matthew Phillips, NWF When trying to understand how ecosystems function, scientists often look at food webs– the complex relationships between animals, insects, plants, and bacteria that govern who eats whom. Food webs in the Gulf of Mexico are as complex as they come. The different habitat types, from forests to wetlands to ocean, mean a diverse array of species. The Gulf food web would be nearly impossible to understand in its entirety, but we can simplify it into a chain to help us think about it. Plants form the base of this chain, as they convert sunlight into the energy that fuels the entire system. Plants are eaten by herbivores, who are then eaten by larger organisms. Scientists can learn a lot about how an ecosystem functions by studying the ends of the chain––the plants at the bottom and the animals that occupy the top. However, it’s the species in the middle that provide crucial linkages. Oiled marsh One recent study, “Disturbance and recovery of salt marsh arthropod communities following ...
Burmese Pythons are killing the rabbits in the Florida Everglades 21.3.2015 Environmental News Network
How exactly DID Burmese Pythons get so numerous in the Everglades?  Were they released by owners who didn't want them and they found they liked the ecosystem?Nearly 80 percent of radio-tracked marsh rabbits that died in Everglades National Park in a recent study were eaten by Burmese pythons, according to a new publication by University of Florida and U.S. Geological Survey researchers.  A year later, there was no sign of a rabbit population in the study area.  The study demonstrates that Burmese pythons are now the dominant predator of marsh rabbits, and likely other mid-sized animals in the park, potentially upsetting the balance of a valuable ecosystem.

As lakes become deserts, drought is Iran's new problem 21.3.2015 Yahoo: Politics
Nazar Sarani's village in southeast Iran was once an island. Climate change, with less rainfall each year, is blamed, but so too is human error and government mismanagement. Iran's reservoirs are only 40 percent full according to official figures, and nine cities including the capital Tehran are threatened with water restrictions after dry winters. The situation is more critical in Sistan-Baluchistan, the most dangerous area in Iran, where a Sunni minority is centred in towns and villages that border Pakistan and ...

Kansas high school finds 27 positive tuberculosis cases 19.3.2015 Yahoo: US National
(Reuters) - Twenty-seven people have tested positive for tuberculosis at a suburban Kansas City high school where a student was recently found to have an active case, Kansas state and county health officials said on Wednesday. Health officials have tested more than 300 students and staff at Olathe Northwest High School after possible exposure to tuberculosis since the active case was reported two weeks ago, officials said. Lougene Marsh, the director of the Johnson County Department of Health and Environment, said the number of people with TB infection does not exceed expectations.

BP Labors to Cast Doubt on Gulf Spill Study It Dislikes By Bryan Gruley & Bradley Olson, Bloomberg Business. March 11, 2015 “As the five-year anniversary of the spill nears, BP is waging a public campaign to promote the idea that the gulf has largely recovered. The company’s public statements have hewed closer to the adversarial tone of litigation than the conciliatory stance the company struck immediately following the well blowout, which killed 11 men and fouled Gulf Coast beaches from Texas to Florida.” (Read More)   US Gulf Coast Prime for Wetlands Restoration: Study By Katy Sater, The AnthropoZine. March 12, 2015 “Since the 1930s, Louisiana has lost an area of wetlands equivalent to the size of Delaware, and it continues to lose a football field of wetlands every hour. If current loss rates continue, by the year 2040 more than one million acres of wetlands will be gone – and the carbon stored in these ecosystems will be released into the atmosphere.” (Read ...
Wetland restoration can help reduce greenhouse gas emissions 11.3.2015 Environmental News Network
Restoration of wetlands can reduce greenhouse gas emissions. This is shown in a report that has been written in part by researchers from the University of Gothenburg. Former wetlands that have been drained and which are currently used for forestry and agriculture give off 11.4 million tons of carbon dioxide equivalents. That can be compared with Sweden's total emissions of 57.6 million tons (when the land use sector is not included). But in Sweden's report to the Climate Convention, emissions from drained peatland are not visible since they are included with forest growth.
