Greybeards of the ACE

Live oaks, the signature trees of the ACE Basin and the most readily recognizable, for centuries have provided shade, mast, wildlife habitat and great enjoyment both for residents and visitors.

Among the drooping beards of Spanish moss, a white-eyed vireo sings its endlessly repeated chick-a-perweeoo-chick. From across an open field, a wood peewee plaintively whistles its own name. Above, on the massive limbs, dried resurrection ferns wait for the next thunderstorm as a pair of fox squirrels race through the maze of branches.

Live oaks take a very different approach from most oaks, the latter characterized by tall, straight trunks with simple horizontal limbs toward the top. Instead, live oaks develop a short, stout trunk and then send twisted branches in all directions producing a large canopy with no central core.

While woodworkers prize most oaks for their straight, easy-to-work grain, live oaks have little commercial value, although shipbuilders long ago sought them for ribs and bow stems for wooden sailing craft. The twisted grain, which gives the branches their strength, thwarts any type of saw. Small pieces make good firewood, but no splitter can cleave larger sections, especially if the wood is given time to dry.

The Richardson Oak at Donnelley Wildlife Management Area, for example, has a huge horizontal limb that stretches eastward from the trunk at least 65 feet.

Botanists classify them as red oaks, but live oaks act more like white oaks. Their acorns mature in one season, not two, and do not have a bitter taste. Each fall, many live oaks drop a huge crop of mast, an important food source for wildlife from deer to squirrels to turkeys to quail and countless other animals.

In good mast years, acorns make up as much as 76 percent of the white-tailed deer diet, and because acorns decompose slowly, they provide nutrients for eight months out of the year.

Unlike most oak species, this unusual tree does not lose its leaves in the fall, so it appears “live” throughout the winter. Come spring, new growth quietly replaces most of last year’s foliage, but the tree remains green all year.

Long before paved driveways, live oaks, with their extensive root systems, probably reduced mud and standing water on the entrance road, and the leafy branches contributed cooling shade to the house.

While a number of ACE Basin plantations have ancient avenues of oaks, in many cases the plantation house sits far back from the public road, and passersby cannot see the oaks. White Hall, The Bluff and Laurel Springs offer a few exceptions.

An orchard oriole, lost to view in the extensive foliage, sings every few seconds. In the distance, I hear the songs of all three of the coast’s most colorful tropical finches—painted bunting, indigo bunting and blue grosbeak.

A healthy poison ivy vine, climbing a V-shaped oak trunk, sports ripening berries that promise winter nourishment for many avian species, especially the sapsuckers that seem to relish them.

But buffeted by onshore winds and salt spray, they usually remain small and stunted—just as interesting as their upland counterparts but not as majestic.

Almost anywhere you wander throughout the 350,000-acre ACE Basin project you will encounter the area’s signature tree and all the wild species it helps support.
