Killer Rhododendron?

The Forestry Commission in England (http://www.forestry.gov.uk/pramorum) has identified diseased rhododendron (an alien but popular shrub) as an important reservoir of the fungal-like pathogen Phytophthora ramorum that causes Sudden Oak Death (that arrived here from the USA in 2002). In addition to killing mature oaks, the agent is also fatal to a range of other mature trees. It has been suggested that this agent, if unchecked, will cause losses to UK habitats on the scale of those seen after Dutch Elm Disease. The Forestry Commission are so concerned (especially in areas like the New Forest) that they have launched a multi-million pound initiative to remove and burn rhododendron in woodland locations. Rhododendron (much loved by Victorians) has, of course, also caused problems in locations like Snowdonia and Brownsea Island by choking native vegetation. It is difficult to eradicate because of its persistent root system and unattractiveness to most insects. This really doesn't seem like a new news story. Perhaps it's part of the continuing vendetta of many agencies against the rhododendron?
