The Oak Stands Tall

The eastern United States' mightiest tree, the oak, is in decline, possibly due to over-harvesting or climate change. Whatever the cause, scientists are trying to find ways to reverse this decline. Watch U.S. Forest Service researchers use fire to give young oaks room to grow in the North Carolina mountains.

Nutty Nuggets

Before I say anything about the importance of acorns in the forest, it’s important to start with the fact that the world’s biggest acorn is in Moore Square Park in downtown Raleigh. It’s fitting to find it there. After all, Raleigh calls itself “The City of Oaks.” And if it were real, there's no doubt this nut would produce a giant oak. The big nut is 10 feet tall and weighs about 1,250 lbs.

Acorns Count

The acorn is not only a symbol of fall, but the nuts are a baseline indicator of the current and future health of the forest ecosystem. U.S. Forest Service researchers studying acorns find a bounty of acorns indicates healthy trees and a plentiful food supply for the creatures that form the base of the forest food chain.
