Краткое описание

The first reported finding of Cryphonectria parasitica (Sweet Chestnut Blight) by the Crown Dependency of Jersey.

Опасность

A number of symptomatic trees in the wider environment have tested positive. The origin of the outbreak is not yet known. C. parasitica infection is usually fatal to European (Castanea sativa) and North American (C. dentata) sweet chestnut trees. It has almost wiped out North America's sweet chestnut population. Although losses have not been on the same scale in Europe, sweet chestnut blight has spread steadily throughout much of Europe, and tree losses have been regionally significant.
