How to Take Down a Dangerous Tree
Follow along with the pros while a tree in peril is carefully felled before storms can send it tumbling
When the chain saw's insistent roar abruptly stops, the crown of a beleaguered black locust tree pivots, then plunges earthward, its green leaves whispering a final, frenetic whoosh. As it hits ground, the branches let loose a cacophony of cracks, snaps, and pops. All that remains of the 70-foot tree in front of a Somers, New York, home is its 45-foot trunk, leaning like the Tower of Pisa down the steep hill and toward the driveway.
In the momentary silence, Dan Swim, an arborist for explains the tree's awkward tilt: The shade of a nearby oak had forced it to reach for light in the opposite direction. This, in combination with several unusually dry years followed by a couple of very wet ones, had caused the roots to gradually lift out of the soil; the next big storm could have splayed it across the driveway (or the road below). "There's no question that this tree - dying and on an incline - had to be felled," says Swim.
The chain saw roars back to life, silencing conversation, and Swim's men quickly carve the tree into manageable chunks. After feeding its smaller branches through a chipper and setting aside the 18-inch-diameter logs for milling, they exchange chain saws for leaf blowers and clean the chipper remnants from the driveway. In less time than it would have taken to rake its leaves on an autumn afternoon, the locust is reduced to a wide, harmless stump. "We always try to work with and preserve nature," says Swim. "But in the end, human safety takes precedence."
Professional roping and removal of limbs
Since the tree to be removed is next to a driveway where a cherry picker can be parked, for the first
step of the process—lopping off the limbs—Angel Galvez has the luxury of standing in a bucket instead of hanging from a rope harness. He works from the
bottom up, so that nothing obstructs each branch's descent. To give the crew control of the limb, they will lower it on a line looped over a branch like a pulley. "A 100-pound limb can hit with a 200-pound force after free-falling just a foot," explains Swim. Angel ties a rope to the limb using a running bowline knot. Cinching it tight, he tosses the line over the crotch of a higher limb and down to his brother, Gonzalo, who loops it twice around the trunk and holds the end. After Angel slices through the limb using a chain saw with a short 18-inch bar, Gonzalo eases the branch to the ground with the rope, then slips the knot free
