Conduct Investigations<br />

Trace Forward Investigation:<br />

Initiate trace forward investigations. Identify all domestic and international shipments of the High<br />

Risk HAP Genera: Camellia, Rhododendron, Pieris, Viburnum and Kalmia and HAP shipments of<br />

the infected plant species within the 6 months prior to the first positive detection of P. ramorum at<br />

the nursery as per the protocol. This information on shipments needs to be gathered, processed,<br />

and forwarded to Regional Office within 10 working days. Reporting trace forwards within 10<br />

days is essential. If requested or necessary, Smuggling Interdiction and Trade Compliance (SITC)<br />

or Investigative and Enforcement Services (IES) may be asked to assist in the information<br />

gathering, as appropriate. The Regional Offices will forward these domestic lists to the States that<br />

have received plants. Headquarters will inform international trading partners of shipments to their<br />

countries. The plants sent to the receiving States must be inspected at the receiving nurseries.<br />

Use the Trace Forward <strong>Protocol</strong> posted at<br />

Trace Back Investigation<br />

Once P. ramorum is confirmed in a nursery, determine if the positive plant(s) was shipped in<br />

from another nursery. Trace Back plants include all plants of the same taxon (i.e., species,<br />

hybrid, variety, or cultivar) of the infected plant regardless of size, location or lot. The trace back<br />

should continue to the original propagation source, if still existing. Forward the Trace Back<br />

List(s) to PPQ’s Regional Office within 10 business days. For the Trace Back <strong>Protocol</strong>, see<br />

http://www.<strong>aphis</strong>.usda.gov/plant_health/plant_pest_info/pram/protocols.shtml#response<br />

<strong>Nursery</strong> Sites:<br />

Determine whether additional locations (nursery sites) are maintained by the same nursery personnel,<br />

or if HAP move to other sites or between sites.<br />

• Equipment: Determine if equipment used at the site is shared with other nursery sites<br />

or field areas. Document any shared equipment utilization in different nursery sites or<br />

field areas. Equipment movement without appropriate biosecurity measures (See<br />

Appendix 9) between nursery sites requires that all nursery sites utilizing the equipment<br />

be included under this protocol.<br />

• Plants: Determine if HAP move between sites. If so, than all sites receiving HAPs<br />

must be included under this protocol.<br />
