Natural wonders: Mt. Rainer's glaciers; wacky animals decline; the little bat that could; repurposing waste wool

At 14,410 feet, Mount Rainier is the highest volcanic peak in the contiguous United States. It boasts the largest alpine glacial system outside of Alaska and contains the world's largest volcanic glacier cave system. It is the Mount's unearthly "frozen labyrinth tucked within the majestic volcano's east crater" that scientists are now daring to explore, reports Rebecca Dzombak of National Geographic. "The glaciers atop Mount Rainer, which towers to the southeast of Seattle, Washington, contains clues about the volcano, the inner workings of glaciers, and even icy worlds far from Earth."

In 2002, America's wacky animals -- think the great American llama, ostriches and emus -- flourished in the lower 48 states, Alaska and even Hawaii. Today that is no longer the case. All our "looney" animal populations have collapsed while other farm animals continue to thrive, reports Andrew Van Dam of The Washington Post. "From 2002 to 2022, we lost 83 percent of our ostriches, 79 percent of our llamas, 74 percent of our emus and 63 percent of our elk. Over that period, cattle were down just 8 percent, poultry was up 16 percent, and hogs were up 22 percent." The farms in Alaska and Hawaii no longer exist.

Cute as a button and confounding to scientists, Alaska's little brown bats have escaped white-nose syndrome. Can their "niche" in nature save them? "Meet Myotis lucifugus, commonly referred to as the little brown bat," reports Trina Moyles for Hakai magazine. Or, as chiropterologist (bat researcher) Jesika Reimer fondly calls it, 'the flying brown bear.'. . . Scientists know little about where [these bats] live at this far northern margin of the species' range."

Across North America, stands of trees of all different species are struggling to survive climate change. In response, scientists from the Cutfoot Experimental Forest are introducing some southern tree species to more northern regions, reports John H. Tibbetts of Knowable Magazine for Inverse. The survival of a grove of bitternut hickory trees, common to Illinois but transplanted to north-central Minnesota, is an example. "Normally, if a southern-adapted seedling is planted in an unsuitably cold climate like this one, it can risk frost damage, and its survival is threatened. . . . Today [scientists]can see the success of almost all the southern trees they planted."

Sheep farmers have developed a new way to repurpose coarser wool or "waste wool" that would have been thrown away by using a wool pelleting machine, reports Elise Konig for Ambrook Research. "A pelleting machine transforms the fleece’s long strands into cylinders that can more easily be handled. The pellets are then sold as soil amendments, providing water retention, nutrient recycling, and soil aeration."

Are you ready to clean, prune, test your soil, pick the plants and snuggle them in some soil? March is get-ready to garden month, and there's lots to do. "If you’ve been itching to get out and get gardening, we’re on the cusp of the season. This is the time to get organized and get ready because by the time we talk again in April, we will be in it, writes Amanda Blum for Lifehacker. From tidying the garden to splitting bulbs to fertilizing shrubs, Blum has a list of all the jobs to do before planting begins.
