Root of all Evil Getting a 130,000-pound laurel oak out of the ground proves to be a devilish taskBy John Garrity
It's this tree that's a problem. This tree, a 65-foot-high, 130,000-pound laurel oak with a trunk 30 inches in diameter and a root ball 20 feet in diameter, doesn't want to leave its home on the left side of the 13th fairway at the University of Florida Golf Course. I have roots here, the tree seems to be saying. So far, those roots have broken two 5/8-inch steel cables that a crew from Capital Tree Relocators of Austin, threaded under the oak's root ball. The cable, strung between a big excavator and its shovel and maneuvered by a machine operator with the dexterity of a vascular surgeon, usually cuts like a band saw through the taproots of a tree. To this tree, it's just dental floss; the cables lie in the red dirt, their steel strands unraveled and split. "This has me stumped," says Shaun Welborn, scratching his head.
The tree-moving has gone well until now. This morning Welborn had watched a crew of six move a tree with a 20-inch trunk and 16-foot root ball from the vicinity of the new 14th green to a spot 150 feet away. A few days earlier, the crew had dug a trench around the tree with a backhoe, cutting the outermost roots. After that the workers had begun to wrap the root ball in two layers of burlap and secured it with wire. "There's an equation you use to get the right size root ball," Welborn says. "You don't want to cut too many roots." Then a platform had been positioned under the tree by sliding about 30 three-inch steel pipes beneath the root ball. "The tricky thing on this site is the dry soil," Welborn says. "It's like powder." To tighten the soil and comfort the wounded trees, Welborn prescribed 750 gallons of water per day per tree for two weeks, delivered by an 850-gallon tank affixed to a tractor. The cost to move each of the 12 trees is about $8,000 -- a bargain, given that a 50-year-old oak sells for about $50,000.
So you can imagine how Welborn feels this afternoon, wrestling with an oak that is holding on like a crying toddler. "We're going to try a one-inch cable," he says, "which almost triples your strength capacity." Unfortunately, Welborn's crew doesn't have a one-inch cable, and that pretty much shuts down work on the tree for the day. From the second-floor windows of the clubhouse, members of the renovation committee can see that the crane isn't moving. They aren't particularly worried, though, because the work has been going well (aside from a mishap in which an excavator tore into a buried effluent line, soaking the 7th fairway). Already, eight holes have been tilled, four greens have undergone rough shaping, and workers are installing 18-inch-circular PVC drain tiles in trenches in the 1st fairway. "I'm pretty much ahead of schedule on every line item," says Tom Weber, project superintendent for MacCurrach Golf, which is handling the construction. "It's a good sign to have this many things going in Week 2." The next morning, under a sky darkened by smoke from out-of-control brush fires across Florida, Welborn's men repeat their flossing antics with a one-inch cable. This time the cable saws through the roots, and the crane lifts out the big oak with no difficulty. Standing at the edge of the pit, Welborn stares with fascination at the top of the severed taproot, which resembles a polished disc of petrified wood smeared with artistic dabs of red clay and pulverized white root. Near the center of the hole is the splintered trunk of a dead pine, buried for 100 years or so and hard as stone. "You can see how tough this was," Welborn says, referring to the removal. "It's the first time I've ever had to use one-inch, and we work with clay everywhere." Forty minutes later, dangling from the crane, the tree arrives at its new address between the practice range and the 13th fairway -- tall, poised and with not a leaf out of place. Next time, we'll pile into the Florida golf team's van for a trip to the farm at Pike Creek Turf in Adel, Ga. We'll meet Jimmy Allen, bermuda-grass merchant extraordinaire, and tour his fields of "fumigated, certified" TifSport and Tifdwarf -- the grasses that will soon cover This Old Course.
