Sulfate concentrations continue to decline in Northeast U.S. streams, according to a new analysis of 40-years' worth of water quality data from relatively pristine watersheds across the country. The analysis shows the effectiveness of the Clean Air Act and the value of a unique stream monitoring network that has faced frequent threats of having its budget cut.
The U.S. Geological Survey's Hydrologic Benchmark Network covers stream sites in watersheds that have seen little disturbance from humans through activities like urban development, agriculture or dam building. The HBN launched in 1963 and once had as many as 59 sites, but has since been slimmed down to 37. A USGS gauge measures streamflow at each site and a smaller set of sites are sampled for water chemistry.Read More
When pigs get out of their pens, they can really tear up a landscape. Five million pigs in 39 states can tear up a lot of landscape.
“They’re one of the top 100 invasive species in the world. Anywhere wild pigs are not natural and they show up, they do a lot of damage to other species,” said Dwayne Etter, a research specialist with Michigan’s Department of Natural Resources and a part of a research team that tested a new feral swine monitoring technique that uses environmental DNA.
Environmental DNA (eDNA) is genetic material organisms lose in the environment. If a pig crosses a creek or defecates in it, a researcher, in theory, should be able to pull that DNA out of the water further downstream.Read More
Since its population bottomed out, the federally-endangered Piping Plover in the Great Lakes has made a comeback for the ages.
A population that once measured approximately 17 pairs and rebounded, hitting 76 pairs in 2017. The same year that count was made, the plovers had also returned to Gull Point, a nesting location that hadn’t been used in more than 60 years.
In an effort to understand some of the conditions that have allowed this species to return to its habitat, researchers have directed their attention toward a curious instrument for help.
A buoy that floats off the coast of Presque Isle State Park , near where Gull Point is located.Read More
