Not So Ancient After All

While President's Day (Feb. 16) was a holiday for most federal employees, it marked the end of the road for two large, old white oak trees on the former Wilson estate, which were cut down to make way for construction associated with the new Clinical Research Center. In an irony of the calendar, one of the trees dated back some 192 years to post-Revolutionary times, when Thomas Jefferson was in the midst of his White House tenure. Both timbers are slated for reuse in historical exhibits.
Old No. 154, just prior to falling.
It had been thought by some community members that the older of the two trees, an 80-foot oak dubbed No. 154 in a census of trees taken on the CRC site, may have been 300 years old (though an arborist retained by NIH estimated a range of 175-300 years). An effort was mounted to spare the tree, but a variety of options to do so were considered too costly and disruptive by NIH. The National Capital Planning Commission reviewed the debate and concluded last December that NIH could go ahead and remove the oaks. In an effort to respect nature's endowment of old trees, however, NIH amended the design of Center Drive to retain one old oak that had been scheduled to fall, save another dozen trees by realigning a construction fence and preserve a third of the trees affected by CRC construction by replanting them elsewhere on campus.
Large cranes arrived on campus Saturday, Feb. 14 to delicately cart away the two oaks' massive trunks, whose bulk had to be preserved intact in order for them to fulfill their new roles: a 35-foot segment of No. 154 weighing more than 14 tons was claimed by the U.S. Navy for use in restoration of a historic battleship -- the U.S.S. Constitution. A 20-foot piece of the second tree, about 92 years old, went to the Friends of Pierce Mill, an historic old structure in Rock Creek Park in need of a new waterwheel shaft. Crews from the National Park Service, which has jurisdiction over Pierce Mill, conducted removal of the lesser oak.
"NIH is really pleased to have found a way to ensure that these oak trees will retain a place in history through their use for restoration of projects important to the community and country," said Jan Hedetniemi, director of NIH's Office of Community Liaison.
"The Navy was thrilled to have the tree," she reported, "because it has such a close grain. It will be used to replace worn decking on the ship."
A 12-inch cross-section of No. 154 was sliced out for preservation as a possible heirloom for the future CRC. A highly respected millwright, Derek Ogden of Madison, Va., has been retained to care for the relic, which might one day serve as an historical exhibit; its rings could be indexed to highlights in both medical and NIH history.
It was last fall's controversy over removing the trees that brought the availability of fresh, stout oak to the attention of the Friends of Pierce Mill.
"They heard the publicity, and had been searching for a source for a new waterwheel shaft," explained Hedetniemi. "So we donated that, too."
There was another diseased oak in the vicinity of the CRC site, though not within it, that had to be cut down, she added. Pieces of that tree were also given to Pierce Mill for use in millhouse cogs and wheels.
Only the sawdust and small limbs from the three mighty oaks met the same fate as more minor flora on the site, but this, too, was not inglorious -- the chips will be reused eventually as mulch.
The reconfigured Center Drive permitted groundskeepers here to replant 78 trees, a task Hedetniemi characterized as arduous. She said NIH has been in touch with the Audubon Society about establishing a wildlife habitat somewhere on campus. "There is some hope that we can do it in conjunction with the Navy, across the street," she said. "The same experts who advised the National Institute of Standards and Technology and the Patuxent River Naval Air Station about their habitats is helping us decide."
Hedetniemi said that no one showed up on Feb. 16 to protest the trees' removal, though authorities here anticipated that there could be some opposition. It turns out that not many people could tell tree No. 154 from any number of its distinguished neighbors. "It was tucked behind a tree we call the Elephant oak (so named because of its peculiar shape, with a bough extending nearly over Center Drive), which is set to remain standing."
Hedetniemi says those who opposed the felling of old No. 154 "did a great service in bringing awareness not to indiscriminately remove ground cover and big trees."
