BOISE, Idaho — A 10-story-tall giant sequoia that was moved two city blocks on giant rollers last summer has new growth and appears happy in its new location, a tree expert said Wednesday.

Tree mover David Cox of Environmental Design examined the 800,000-pound sequoia in Boise, Idaho, and pronounced the tree fit.

Naturalist John Muir, who played a key role in establishing California’s Sequoia National Park, sent the tree as a seedling to Boise more than a century ago.

It was planted in the yard of a doctor’s home across the street from a hospital that’s now undergoing a major expansion with new buildings, meaning the tree had to be moved or cut down.

“She looks pretty good,” Cox said after his inspection. “But it’s still too early to tell. You still need about two or three growing seasons to really say that she’s recovered. We’re not in any danger zone. We feel like the tree is still happy.”

Moving the tallest tree ever attempted by the company required cutting back the root system that’s now being monitored for moisture content with underground sensors at the tree’s new location on city property.

“We’re in a new environment here, a little more open,” Cox said. “We don’t know if we’re going to be better off or worse off. Se we’re going to prepare for drying winds.”

Cox said he plans to make site visits in January and again in March or April to consider treatments for the growing season for the sequoia, which are known to live for several thousand years in the right conditions.
