In line with longstanding initiatives to expand its green spaces, New York City is planting
with just plain beauty.
Something could go wrong, though, according to a new study. Oaks and sweetgums, which
currently account for a majority of the city’s trees, produce huge amounts of a chemical substancecalled isoprene. Harmless by itself, isoprene interacts rapidly with polluting nitrogen oxidesreleased by vehicles, buildings and industry to form ground-level ozone( )-a major factor in
many breathing problems.
The research, carried out by scientists at the Columbia Climate School and other institutions,
found that if the city maintains past species patterns in new plantings, isoprene production inManhattan in coming decades will go up by about 140%, and resulting summer ozone levels asmuch as 30%
“We’re all for planting more trees. They bring so many good things,” said study coauthorRoisin Commane. “But if we’re not careful, we could make air quality worse.’The Parks Department is not ablivious te the issue. A study carried out by some of itsresearchers several years ago concluded that city trees did release isoprene. “We didn’t make a bigdeal of that,” said Novem Auyeung. a Parks Department senior scientist. She said trees should notbe viewed as the enemy. “We could plant any trees we want to, if we just rethink our car-centriclifestyle,” she said.
“We’re not going to go cutting down any big old oaks, and neither will the departmentcompletely stop planting new ones,” said Auyeung. “You have to think about what you would loseif you do that.” Oaks are keystone species, she pointed out, providing food and habitat for native
insects, birds and other animals.
