Chestnut researchers rally to fight the blight for good
Chestnut trees disappeared from 200 million acres of forest from northeast Mississippi to southern Maine 100 years ago. The social and ecological significance of such an event, which led to the loss of at least 1 billion trees, can be hard to understand today.
The massive die-off of the American chestnut left a big hole in the ecological fabric of Southern Appalachia and beyond. The tree dominated the forests in size and in the ecological and human services it provided.
While no tree could fully substitute an American chestnut in providing food for wildlife, naturally increasing acorn production from oaks served as a major food source bridge for wild turkey, bobwhite, white-tailed deer and squirrels. The oaks helped fill in the so-called “chestnut gap.”
Try as they might, the oaks never produced the same bountiful harvest.
Now with the work of the 3BUR (Breeding, Biotechnology and Biocontrol United for Restoration) the fight to protect the American chestnut and restore it to the throne of the forest is again in motion.

Southern Appalachians show red as a warning on new detailed biodiversity maps

SYLVA — Great Smoky Mountains National Park has long been known for its abundance of different species of flora and fauna.
Credit old mountains in a warm, sunny and wet region with varying types of climate, soil and stone for that large number.
“The park is almost certainly the most biodiverse national park in North America,” said Paul Super, national park science coordinator. “And certainly the most studied of any national park.”
A group of environmental organizations recently put together a series of maps illustrating the regions with the biggest threats to their biodiversity, and the area around Jackson County and the national park showed up in the red, showing risk. One such map, based on NatureServe data, is among the most detailed maps of endangered and threatened species ever produced.
