One of the American Chestnuts (Castanea dentata) planted in Prospect Park a dozen years ago has succumbed to the pathogenic fungus Cryphonectria parasitica, the dreaded Chestnut Blight. This is in stark contrast to the tree right next to it, which is long with leaf now. But the death was inevitable: these were non-resistant trees. There are, however, some newly planted resistant hybrids nearby.
