Plain Language Summary

The brown spruce longhorn beetle (Tetropium fuscum (F.)) is an invasive forest insect from Europe that infests spruce trees. It was discovered in Halifax in 1999 but has been established in Nova Scotia since at least 1990. It likely arrived in wood packaging aboard container ships. It is not known to be established elsewhere in North America.

From 2012 to 2014, the Province of Nova Scotia conducted a pest risk analysis (PRA) of its forests because of brown spruce longhorn beetle (BSLB) discoveries outside the containment area and the need to re-evaluate BSLB risk management in light of successes, failures and new science. To carry out the PRA, the Province used the Risk Analysis Framework developed as part of the National Forest Pest Strategy under the Canadian Council of Forest Ministers.

The risk assessment shows that BSLB poses a low to moderate risk to Nova Scotia forests. The possibility of BSLB occurring throughout the province is high, but the magnitude of the consequences to date in economic, social and environmental values is low. Moderate to high uncertainties and information needs elevate the overall risk assessment of BSLB from low to low–moderate.
