The Food & Environment Research Agency (Fera) said the pathogen Phytophthora kernoviae has been detected on a bilberry (Vaccinium), in Cornwall. It causes bleeding cankers on trees and leaf blights on shrubs.

The first cases appeared in Cornwall in 2003 at three nursery sites and public gardens, but in 2008 Defra confirmed the first discovery in the wild of P. kernoviae on bilberry - making it a threat to native heath land across Britain, according to Defra. Cases have since been reported in Wales and Scotland.
