North America once had 400 million beavers. Nearly wiped out by the 1900s, they are now restoring rivers, wetlands and wildlife one dam at a time

Once nearly eradicated due to extensive fur trapping, beavers are making a notable comeback in North American rivers. Their innate talent for constructing dams contributes to the formation of ponds and wetlands, which support a wide array of wildlife. The rejuvenated habitats formed by beavers enhance resilience against droughts and…

A California wildlife biologist risked cliff falls and eagle attacks to monitor and foster bald eagle chicks; by 2018, the Channel Islands had 20 breeding pairs

Bald eagles have been successfully reintroduced to California's Channel Islands. Decades of dedicated conservation efforts brought these birds back from local extinction. This recovery also aided the resurgence of native ecosystems and island fox populations. The successful restoration now serves as a model for ecological recovery. These islands are a…

In 1939, a wildlife biologist hiked 1,700 miles through Alaska's Denali to learn why sheep were vanishing; he found winter, not wolves, was to blame

Wildlife biologist Adolph Murie studied Dall sheep and wolves in Denali National Park. His research revealed severe winter weather caused the sheep population decline. Murie's findings showed wolves preyed on weakened sheep, not causing the overall decrease. This influential study shifted conservation focus to ecosystem-based wildlife management. Murie's work championed…

For 30 years, a Hawaii botanist climbed 3,000-foot sea cliffs without a rope to hand-pollinate tiny flowers and returned months later to collect their seeds

Botanist Steve Perlman undertook dangerous climbs to hand-pollinate rare Hawaiian plants. These unique species face extinction due to habitat loss and invasive threats. His efforts involved scaling treacherous sea cliffs to reach inaccessible plant locations. Seeds collected are stored and cultivated to restore dwindling plant populations. This dedication highlights the…

In America’s Great Lakes, invasive mussels made the water look cleaner but broke the food chain; native whitefish could now vanish from some areas within five years

Invasive zebra and quagga mussels have transformed the Great Lakes ecosystem by reducing the tiny organisms that young lake whitefish depend on for food. While the mussels made the water cleaner, they disrupted the food chain, causing whitefish numbers to fall sharply. Scientists warn the species could vanish from some…

In 2024, a study assessed peacock bass invasion risk across Neotropical freshwater ecoregions; several remain hotspots for future invasions

A study identified freshwater regions vulnerable to yellow peacock bass invasions. Climate change and dam construction increase suitable habitats for this predatory fish. Southern and northeastern Brazil, and Central America face the highest invasion risks. Preventive conservation efforts are crucial before new species are introduced. Targeted monitoring and management can…

In the late 1800s, America imported mute swans to decorate parks and estates; their descendants later damaged wetlands and displaced native waterbirds

Mute swans, introduced for their beauty, now pose an ecological challenge. These birds consume vital underwater vegetation, impacting native species and habitats. Their aggressive territorial behavior also displaces native waterfowl during breeding seasons. This gradual expansion has altered the delicate balance of the Chesapeake Bay ecosystem. Conservation efforts now focus…

In the early 1900s, America planted European beachgrass to hold coastal sand in place; it later transformed natural dunes and displaced native wildlife

European beachgrass was introduced to North America over a century ago for dune stabilization. This invasive grass significantly altered coastal dune ecosystems and native plant diversity. Its dense root systems stabilized dunes but disrupted natural sand movement processes. Restoration efforts now focus on removing the grass and re-establishing native vegetation.…
