(P. ramorum)

A little background to start...

In Europe, including the UK, P. ramorum has been found mainly on container-grown Rhododendron, Viburnum and Camellia plants in nurseries. It was first detected in the UK in 2002, when emergency measures were introduced. The initial measures included destruction of infected plants, a ban on imports of susceptible material from affected areas of the USA, and notification of movements of susceptible nursery stock. These measures were notified to the EU Standing Committee on Plant Health, which agreed EU-wide emergency measures in November 2002, based largely on the UK's action. Those measures are still in place.

Phytophthora ramorum was first identified in the mid-1990s as the cause of widespread devastation of wild oak trees in California and Oregon, USA (which earned it the name 'Sudden oak death').

In 2010, P. ramorum came to the Glenariffe Forest Park in the Glens of Antrim. The removal of infected trees has had a serious impact on the landscape of the area.
