An invasive species is doing a number on New Jersey trees.

State agriculture officials say gypsy moths have moderately or severely damaged nearly 2,900 acres of trees statewide.

Last year, the leaf-eaters only chewed through about a thousand acres' worth of trees.

That's the lowest mark since New Jersey started tracking this activity in 1970.

Still, officials say gypsy moth populations are cyclical.

They'll conduct a survey this fall to determine whether spraying is necessary.
