  • Can Fungi Save This Endangered Hawaiian Tree?

    Conservationists in Hawaii are growing seedlings of the critically endangered na’u tree alongside mycorrhizal fungi instead of fertilizers and pesticides to mimic their natural growing process. The fungi support the plant in a variety of ways, like sucking up more water and providing mineral nutrients, which helps the seedlings grow at a rapid pace.

  • The Futures of Right Whales and Lobstermen Are Entangled. Could High-Tech Gear Help Save Them Both?

    Lobster is a crucial economic resource in New England, but entanglements with the fishing line from lobster traps are a major cause of death for endangered North Atlantic right whales. Scientists and lobstermen are testing ropeless, on-demand gear that minimizes the risk for whales and allows fishing to continue in areas that would otherwise be closed for months as the whales pass through.

  • Mini-artificial islands mimic wetlands and help filter Missouri's lakes and ponds

    The Missouri Department of Conservation is installing artificial wetlands in small bodies of water across the state to improve the water quality. The floating plastic islands are anchored to the seabed and hold native plants, allowing the roots to reach into the water below. The plants soak up excess nutrients and toxins, mimicking natural wetlands.

  • How coastal communities are adapting to sea level rise with 'living shorelines'

    Coastal communities in Maine are building living shorelines to adapt to sea level rise and address erosion concerns. This nature-based solution uses native plants and materials, or even discarded holiday trees, to bolster shorelines against strong storms and higher tides. And they get stronger as nature takes its course over time.

  • A New Wildlife Crossing Provides Safe Passage Over a Busy Interstate

    Environmentalists, biologists, wildlife advocates, and even ski clubs formed the I-90 Wildlife Bridges Coalition to push for wildlife crossings to be a part of a massive construction project on Washington’s heavily trafficked Snoqualmie Pass. The Department of Transportation took notice. It's working with other government agencies and wildlife experts to install bridges and tunnels designed for animals of all sizes to safely cross the road.
