Scientists calculated the biomass of various groups of mammals, and humans’ impact weighs heavily on the planet.

Barring any last-minute court decisions, the Greater Rockford Airport Authority will soon resume construction on its cargo expansion project, bulldozing a portion of ancient Bell Bowl Prairie in order to carve out a new roadway.

Despite habitat strongholds in places like Illinois, white-nose syndrome continues to decimate the population.

The deadly white-nose syndrome is threatening the northern long-eared bat — one of Illinois’ 13 native bats — with extinction. The race is on to find a cure and protect what’s left of the population.

Marc Schlossman spent a decade photographing specimens of extinct and endangered species housed at the Field Museum. The result is a new book, “Extinction,” which Schlossman calls an exercise in hope.

Officials are reporting that nine of the endangered bees were found during a recent survey of Lake County forest preserves.

A rare patch of 8,000-year-old remnant Illinois prairie has been granted a new three-month lease on life, as the Greater Rockford Airport Authority has again delayed demolition of the natural area, pending additional environmental review.

One of North America’s most common native bumble bee species, the aptly named American bumble bee, is on the ropes. Among the threats to its survival: competition from honey bees.

Chicago’s birding community is already preparing for the return of Monty and Rose, the piping plovers that captured national attention two summers ago when they made the surprising choice to nest on Chicago's lakefront. But will their favored habitat be secure in 2021?

Trump administration officials are expected to say this week whether the monarch butterfly, a colorful and familiar backyard visitor now caught in a global extinction crisis, should receive federal designation as a threatened species.

Similar in size to the monarch, the regal fritillary is also a stunner in the looks department, but the native prairie butterfly has nearly disappeared from Illinois. To save this pollinator, we need to save the prairie.

Around the world, government resources diverted to pandemic efforts have opened opportunities for illegal land clearing and poaching. Lockdowns also have derailed the eco-tourism that funds many environmental projects.

For the past 25 years, Cheryl Knott and her husband Tim Laman have dedicated their lives to the orangutans that live in Borneo’s Gunung Palung National Park. On Tuesday, they’ll highlight the great ape’s plight with a talk.

Preliminary findings point to the endangered pangolin as a possible host of the novel coronavirus, sparking concerns that a panic could lead to killings of the animal.

Experts say proposed changes to the Endangered Species Act could harm a number of troubled species found in Illinois, including the piping plover shorebird, rusty patched bumblebee and other animals and plants.

After spending their first year at Chicago’s Peggy Notebaert Nature Museum, dozens of endangered Blanding’s turtles were released into the wild as part of a preservation effort that started more than 20 years ago.
