City’s Oldest Tree? It’s...um...probably one of these...; New York, NY

City’s Oldest Tree? It’s Anyone’s Guess - City Room Blog - NYTimes.com:
The question is asked every few years when another living landmark tumbles down: What is the oldest tree in New York City?
The answer isn’t easy.
“The oldest tree in New York?” said Edward S. Barnard, the author of “New York City Trees: A Field Guide for the Metropolitan Area” (Columbia University Press, 2002). “God only knows.”
There are 5.2 million trees in New York City, and tree canopies shade roughly one-quarter of the city, according to estimates by the United States Forest Service. Conventional wisdom, with all its caveats and contradictions, currently holds that the oldest may be the enormous tulip tree in Alley Pond Park, called the Queens Giant. (It is also believed to be the city’s tallest tree.)
