DURHAM, N.H. — The U.S. Forest Service says needles on white pine trees in northern New England, New York and eastern Canada are turning yellow and brown.
They say three fungi appear to be causing the problem. The damage started affecting needles in the middle of branches in May. The needles are expected to fall off by early July.
U.S. Forest pathologist Isabel Munck said the service is working with state departments of forestry in Maine, Vermont and New Hampshire to assess the impact of damage on tree growth.
The summer of 2010 was the first time in recent years that pines in this area showed so much needle damage. The same group of fungi caused that outbreak. A succession of moist springs caused the fungi to be more prevalent.
