Old magnolias never die, they just fade away. That seems to be the fate of the most historic tree at the White House, a Southern magnolia planted by Andrew Jackson and now so ancient and fragile that part of it was dismantled last month.
The decision to take down or at least dismember an old tree is neither easy nor always objective, but professional arborists are guided by a risk assessment protocol that brings a rationality to the process. The evaluation assesses the tree's vigor, the thickness of its sapwood shell, its disease stresses, the state of the roots and the like. Arborists also consider its location and the proximity to what they call "targets" -- property and people.
