  • How seeds from the past are saving a unique flower of the Great Lakes

    By Kyrmyzy Turebayeva More than 30 years ago, a group of scientists planted just 4,200 seeds of the rare Pitcher’s thistle in the sandy dunes of the Great Lakes. At the time, no one knew if the new populations would survive. Today, three decades later, the restored populations are thriving and spreading.

    From otters to butterflies: How Minnesota became a pioneer in nongame wildlife conservation

    By Kyrmyzy Turebayeva In the late 1970s, when most wildlife conservation programs in the United States focused almost exclusively on game species, a quiet but historic shift began in Minnesota. It was here that one of the nation’s first state programs dedicated to protecting so-called nongame wildlife emerged from butterflies and bats to bald eagles and river otters. That story is now told in detail by Carrol Henderson in his new book, “A National Legacy: Fifty Years of Nongame Wildlife Conservation in Minnesota."

  • Michigan’s water infrastructure sees improvements, work still needs to be done

    By Clara Lincolnhol The U.S. would need to invest nearly $3.4 trillion over the next 20 years to fix and update drinking water, wastewater and stormwater infrastructure, says researchers from The Value of Water Campaign. Much of that infrastructure was built 40 to 50 years ago and shows its age. Michigan’s is no exception. The American Society of Civil Engineers gave the state a D+ for its drinking water infrastructure, a D in storm water management and a C for its wastewater infrastructure. Funding is a major problem. Proposed data centers would put more stress on the infrastructure.

The data will be used to create two- and three-dimensional maps to better understand the geological structure at depths of about 10,000 feet.
