For a community of brook trout in the southern Appalachian mountains, there are signs that the good times are coming back. To some, these native inhabitants might even appear to be waving a welcome home sign.
Their numbers almost vanquished, they are as much a cultural emblem of these rugged and lush mountain forests as they are an important signal for the highest quality drinking water. This is what makes their fate of such interest to the millions who live in the surrounding watersheds and to those involved in an inspiring partnership to help them along. They are also the subject of a new film, “Bringing Back the Brooks: Reviving the South’s Trout” produced by Freshwaters Illustrated in partnership with the U.S. Forest Service. Read more »

February is traditionally a month of celebration for our nation’s 1890 land-grant universities (LGUs) in commemoration of Black History Month. These institutions are historically-black universities that were established in 1890 under the Second Morrill Act. Now, as the month draws to an end, the 1890 LGUs are setting their sights on August 30, which marks the 125th anniversary of the Congressional action that created a network of historically black colleges and universities dedicated to providing educational opportunity for all through innovative scientific research and community-minded Extension programs.
“One of the ways we can best honor black history is by providing a proper foundation to support future achievement. Through federal funding and leadership for research, education and Extension programs, NIFA focuses on investing in science and solving critical issues impacting people’s daily lives and the nation’s future,” said Cathie Woteki, USDA’s Chief Scientist and Under Secretary for Research, Education, and Economics.

The Eastern hellbender is the largest salamander in North America, reaching lengths of up to 24 inches. Hellbenders need clean streams with high water quality and silt-free streambeds to find their prey and avoid predators. (Copyright photo courtesy Freshwaters Illustrated/Dave Herasimtschuk)
Hiding beneath a pile of rocks in a clear mountain stream flowing from the Pisgah National Forest in North Carolina lurks North America’s largest salamander, the Eastern hellbender. It is also locked in battle between its perilous decline and valiant struggle for survival.
Sediment from runoff, prescription and over-the-counter therapeutic and veterinary drugs, personal care products such as soaps, fragrances and cosmetics, other chemical pollutants, and the physical disturbance of its rocky lairs by unknowing recreationalists are all suspects contributing to the hellbender’s decline.

Healthy seagrass meadows prevent erosion on coasts, store carbon, and provide marine animals with food and habitat. (National Oceanic and Atmospheric Agency)
Just off Florida’s 8,000 miles of coastline and tidal areas, in shallow sunlit waters, over two million acres of seagrass meadows waft in the ocean currents.
Besides providing food and habitat for manatees, sea turtles, shellfish, and other animals, seagrasses protect coasts from erosion and store vast quantities of carbon dioxide.
“Seagrasses grow off the coast of many other U.S. states, including North Carolina and Virginia, as well as around the world,” said U.S. Forest Service Southern Research Station scientist Zanethia Choice. “Globally, their economic value is nearly $4 trillion.” Read more »
The first step in running a successful farm or ranch business is identifying a product to create and connecting that product to potential customers. For some new and beginning farmers, it can be a challenge to connect to the right market opportunities and to build a business that fits.
At USDA, we are working to make sure that there is access to markets at all levels – so that whether a new or beginning farmer wants to sell locally, regionally, nationally, or globally, they have access to tools that support their business and business development. Read more »
Pickles of many kinds fill grocery store shelves, all of them safe for consumers thanks to the work of an ARS food safety lab in Raleigh, North Carolina.
This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.
Pickles are a popular food, but are even trendier today as more and more craft brands show up in stores and farmers’ markets all over the country. But did you know USDA’s Agricultural Research Service (ARS) has helped commercial pickle-makers, from small brands to the nation’s largest, meet the highest standards of food safety?
While pickling—storing in an acid liquid, usually vinegar—has been recognized as a food-preserver since long before the discovery of bacteria, the kind of data that today’s precise food safety standards require was not established until recently. Read more »
