U.S. Supreme Court changes wetland protections. The Waters of the U.S. ruling alters federal Clean Water Act protections. Some state the decision could negatively impact fish, waterfowl, and other wildlife by favoring development on isolated or ephemeral wetlands. Others applaud the new clarity in support of property rights but emphasize the need to increase voluntary conservation efforts.

Bald eagles removed from Ontario’s species-at-risk list after 50 years, reports the Toronto Star. The province’s Environment Minister stated the ban on the insecticide DDT and collaborative habitat restoration aided the bald eagle’s recovery.

Louisiana legislators to explore black bear management. A recent resolution requests the state wildlife agency to study the feasibility of allowing a black bear hunting season for management purposes. The iconic subspecies’ “threatened” status on the U.S. Endangered Species Act was lowered in 2016 when the population was estimated to have doubled to about 500 bears.

Over 100 burrowing owls released in Canada. Conservationists with the Wilder Institute and Calgary Zoo are celebrating this milestone in recovering the endangered burrowing owl.

Backcountry skiing pushes out endangered bighorn sheep. New science shows that herds of the Sierra Nevada subspecies of bighorn sheep avoid backcountry ski areas in California during winter. Researchers say this interaction must be considered to limit the negative impacts of tourism.

Politics impede wild horse management. Wild horse numbers have exploded to more than 80,000 across the western U.S. and the federal government has spent $500 million on captive care over the last 10 years. As the situation worsens, land management agencies are struggling to deal with political obstacles.

Lions return to protected areas across Africa. Despite a 43% global population decline over the past 21 years, lions are now recovering in large, protected area networks like Mozambique’s rewilded Zinave National Park and the Greater Zakouma Ecosystem in southeastern Chad.

Wild pigs a bigger threat to South American habitat. New research shows that invasive feral pigs are expanding their range and threaten some of the most biologically diverse places across South America. Minimizing the environmental damage and socio-economic impacts of increasing wild pig populations is a major conservation challenge.

Why did the mountain lion cross the road? New research gives a first glimpse at wildlife movements during COVID-19 pandemic lockdowns. Scientists pooled tracking data for 2,300 mammals from 43 species around the world. They found that animals were more active and closer to roads when human activities were reduced from stricter lockdowns.
