City and court records show that $123,000 worth of tickets were doled out for damaging or destroying trees in 2010.
Incidents included a Christmas-night massacre of six saplings at a playground on Houston Street and a contractor who caused major tree damage to five honey locusts on Chambers Street earlier this month.
In addition, vandals tore up 20 new trees and bushes in a playground in the Bronx last October.
Geoffrey Croft of the watchdog group NYC Park Advocates says a street tree costs the city $1,790 to plant, and tampering with its limbs can kill it.
"Some of this is just outright abuse," Croft told the Post.
