64ee68b7-d388-459e-ada3-27708d657f80 United Kingdom 2012-01-30 Revised Rapid Assessment of the need for a detailed Pest Risk Analysis for Phytophthora pseudosyringae This rapid assessment shows: 

Likelihood of entry is: Likely 

Likelihood of establishment is: Established 

Economic impact is expected to be: Difficult to separate the impact from other Phytophthora spp. with which it appears to be associated, but the impact on trees appears minor in isolation, albeit with some uncertainty. The impact on bilberry and the environment in which it occurs is likely to be locally damaging. 

Endangered area: Woodland and heathland areas of the UK where known natural hosts are present; possibly favoured by the presence of waterways and human activity such as walking, mountain biking, etc. Managed gardens may also be favourable to the pathogen. It is possible that western and coastal areas may be more favourable but this is not proven. 

Risk management: No statutory action is recommended.
