Likelihood For "Pest is Introduced" the lowest value of Entry or Establishment, as both are required for a successful introduction. For "Pest Spreads to Maximum Extent" this is an expert judgement on the likelihood of this occurrence. See Guidance Document for more Information Likelihood [1 - 5]		2
Entry The Likelihood of movement of the pest into the UK on a pathway and transfer of that pest to a suitable host. See Guidance Document for more Information Entry [1 - 5]			3
Establishment The likelihood of the pest surviving and perpetuating in the UK for the foreseeable future after it has entered. See Guidance Document for more Information Establishment [1 - 5]		2
Spread The rate at which a pest can expand, by natural dispersal only, within an area. See Guidance Document for more Information Spread [1 - 5]		2
Impact The highest value from economic, environmental or social impacts. See Guidance Document for more Information Impact [1 - 5]			3
Impact - Economic The predicted economic impacts of the pest in the UK. This includes direct effects on yield, quality and possible indirect effects such as trade implications. See Guidance Document for more Information Impact - Economic [1 - 5]			3
Impact - Environmental The proportion of the environmental value of the plant which is likely to be lost through the introduction of the pest. See Guidance Document for more Information Impact - Environmental [1 - 5]			3
Impact - Social The predicted social impacts of a pest in the UK, including effects on tourism, amenities and animal and human health. See Guidance Document for more Information Impact - Social [1 - 5]			3
Value at Risk The value of the hosts or industries at risk from this pest in the UK. See Guidance Document for more Information Value at Risk [1 - 5]				4
Likelihood x Impact The likelihood multiplied by the impact, which shows the risk to the sector. See Guidance Document for more Information Likelihood x Impact [1 - 25]	6
UK Relative Risk Rating Likelihood x Impact x Value at Risk. See Guidance Document for more Information UK Relative Risk Rating [1 - 125]	24

PRA Availability

UK (2015) - NB before taxonomy of the species group was revised and clarified

Regulation and EPPO listing

show / hide

Provisional quarantine pest (Great Britain), quarantine pest (Northern Ireland) (both as Euwallacea fornicatus sensu lato). Quarantine pest (as non-European Scolytidae spp.).

Actions Indicated

show / hide

Action

Statutory action against findings

General Comments

A disease complex involving an ambrosia beetle and fungus, native to Asia but now invasive in other countries. The UK climate is likely to be a limiting factor regarding establishment. Watching brief needed for any pest spread into areas with cooler climates.

Uncertainty

show / hide

Key uncertainty for pest

Repeated taxonomic revisions for the species group mean that older data often cannot be unambiguously assigned to a species.
