New Jersey's Forests Disappearing

The replacement of forests with urban development has been especially rampant over the last two decades, according to the report.

"The study, a collaboration between Rowan and Rutgers universities, analyzed land use data between 1986 and 2007 and estimates the state could run out of open space around 2050 if the pace of development that took place in the sprawl years continued.

'There's less than a million acres left,' said John Hasse, a professor at Rowan University and a co-author of the report. 'We have our last 20 percent.'"
