A man sees only what concerns him. Once started, it spreads via roots from tree to tree and you can never get rid of it. More and more of it is being found in piedmont areas and its spores can be blown 10 -15 miles. It is transmitted by a weevil which inhabits the duff around the base of the tree, but it is very hard to actually find one.
Scotch pine are especially susceptible, but others can be infected if they are stressed.
Rapid removal of dead trees helps. Pine wilt doesn't cause the tops of trees to die typically. They either die from the bottom up or the whole tree dies quickly. It was first identified 15 years ago. They are not likely the primary cause of decline, rather are usually secondary, even with blue stain fungus present.
