Statement of Need: APHIS typically relies on inspection at a Federal plant inspection station or port of entry to mitigate the risks of pest introduction associated with the importation of plants for planting. Importation of plants for planting is further restricted or prohibited only if there is specific evidence that such importation could introduce a quarantine pest into the United States. Most of the taxa of plants for planting currently being imported have not been thoroughly studied to determine whether their importation presents a risk of introducing a quarantine pest into the United States. The volume and the number of types of plants for planting have increased dramatically in recent years, and there are several problems associated with gathering data on what plants for planting are being imported and on the risks such importation presents. In addition, quarantine pests that enter the United States via the importation of plants for planting pose a particularly high risk of becoming established within the United States. The current regulations need to be amended to better address these risks.

Summary of the Legal Basis: The Secretary of Agriculture may prohibit or restrict the importation or entry of any plant if the Secretary determines that the prohibition or restriction is necessary to prevent the introduction into the United States of a plant pest or noxious weed (7 U.S.C. 7712).

Alternatives: APHIS has identified one alternative to the approach we are considering. We could prohibit the importation of all nursery stock pending risk evaluation, approval, and notice-and-comment rulemaking, similar to APHIS' approach to regulating imported fruits and vegetables. This approach would lead to a major interruption in international trade and would have significant economic effects on both U.S. importers and U.S. consumers of plants for planting.

Anticipated Costs and Benefits: Undetermined.

Risks: In the absence of some action to revise the nursery stock regulations to allow us to better address pest risks, increased introductions of plant pests via imported nursery stock are likely, causing extensive damage to both agricultural and natural plant resources.
