News Sentinel:  State takes path of least resistance with air-quality plans; and researchers are gauging how Southern Appalachian salamanders will respond to climate change.

KNOXVILLE — Local journalists delivered a double tap of critical conservation coverage this week:

The state air quality board is outlining its 10-year haze-reduction plan for Tennessee, and some enviros are arguing the state is not going much beyond the bare minimum required by the feds. That was the crux of a detailed report from News Sentinel reporter Anila Yoganathan that also examined lingering air quality and deposition issues in Great Smoky Mountains National Park. While air quality in some aspects has improved in recent decades, there are still some insidious issues that affect the park’s viewshed, and on occasion, the health of park visitors, too. Acid and nitrate deposition continue to take a toll on park streams.

The report is extensive. A digital subscription is required to view the stories at Knox News, but hopefully they’ll open it up as an introductory freebie.

Speaking of streams and the threat they face: 

Science reporter Vincent Gabrielle waded into a story about research at the Tennessee Aquarium delving into the effects of global and regional climate change on Southern Appalachian freshwater denizens such as the black-bellied salamander.

“Their teeming millions make up a substantial proportion of the animal life of a forest. In the headwaters of the Appalachian Mountains, salamanders frequently outnumber fish, birds and other small animals,” Gabrielle reported.

“Lungless salamanders, like the black-bellied salamander, breathe only through their skin. They will notice water pollution, including sediment, agricultural runoff or acidic seepage from old mines, and relocate to cleaner water.” — If they can, we might add. Too often, that is impossible for them.
