Climate change could steal your fish

CHEROKEE — The mountains of the Southern Appalachians were scraped clean a century ago. Headwater ecology changed as the canopy of trees disappeared that was shading the streams from all but the noonday sun. Rainstorms pushed dirt and rocks into the water muddying the feeding and breeding grounds of fish, amphibians and insects. 

Lower down the mountain, newly cut pastures edged right up to the creeks while cows mucked up the once-pristine waters. Invasive bugs killed hemlocks, ash and other shade-giving trees. Pipes, culverts and dams blockaded streams and kept animals from cooler water. 

The trout never had a chance.

Now they face an even more insidious foe — climate change.
