The brown spruce longhorn beetle (BSLB) is an exotic pest of quarantine significance which kills spruce trees. Native to northern and central Europe, BSLB is a direct threat to the forests of North America and a threat to trade in Canadian forest commodities.

To help prevent the spread of the BSLB a Ministerial Order was issued. The order restricts the movement of spruce round logs, unprocessed bark and wood chips, out of the Containment Area in Nova Scotia so as to prevent the spread of BSLB to areas in Canada not infested by the beetle.
