Light at night: monitoring light from communities surrounding the park.

We’re used to electric lights making our nights brighter. But many animals aren’t: from insects to turtles, nighttime lights confuse animals and even threaten some species by changing hunting, migratory, and reproductive behaviors. As part of a nationwide light pollution inventory, NPS employees and volunteers scrambled atop Clingmans Dome on some chilly nights in late October to capture images of the night sky. Researcher Kate Magargal from the Night Sky Program, an NPS initiative based in Ft. Collins, Colorado, said that the most pristine (darkest) night skies are still in the Western National Parks. In the Smokies, light from Pigeon Forge, Knoxville, and even Atlanta spills across our night sky. Look for more detailed information about the impacts of light pollution on the park’s animals (including humans) in future “Dispatches.”

Scientists estimate that 100,000 different species live in the park.

What lives in Great Smoky Mountains National Park? Although the question sounds simple, it is actually extremely complex. Right now scientists think that we only know about 17 percent of the plants and animals that live in the park, or about 17,000 species of a probable 100,000 different organisms.
