Fungus affecting white pine trees in southern New Hampshire
DURHAM — Many people in southern New Hampshire have noticed the needles of white pines turning yellow and brown this spring — and that's due to a fungus called "needlecast."
University of New Hampshire researchers say white pine trees in New England have struggled with needlecast since 2010. Researchers are studying four fungi known to cause needle browning. They say this year's brown needles are a result of last year's wet weather.
Kyle Lombard, forest health specialist with the New Hampshire Division of Forests and Lands, said the tree is otherwise healthy, the brown needles will shed in a few weeks and green needles will be left.
