DOI. Fish and Wildlife Service.
The U.S. Fish and Wildlife Service has finalized a rule that would ban the importation and interstate transportation of four nonnative constrictor snakes that threaten the Everglades and other sensitive ecosystems across the U.S. The final rule -- which incorporates public comments, economic analysis, and environmental assessment -- lists the Burmese python, the yellow anaconda, and the northern and southern African pythons as injurious wildlife under the Lacey Act in order to restrict their spread in the wild in the U.S. For more information, see Large Constrictor Snakes (scroll to view) from FWS' South Florida Ecological Services Field Office and What the Listing of the Four Constrictor Snakes as Injurious Means for People Who Own Snakes (Feb 13, 2012; PDF | 93 KB).

Update -- NAPPRA (Not Authorized Pending Pest Risk Analysis) -- Addition of Plants for Planting to the NAPPRA Lists
USDA. Animal and Plant Health Inspection Service.
The Not Authorized Pending Pest Risk Analysis list (APHIS-2011-0072) of plants and flowers has been published by USDA for public comment. The NAPPRA list are those plants which could be prohibited for import into the U.S. until a pest risk analysis has been completed for them. APHIS has prepared data sheets that detail the scientific evidence it evaluated in making the determination that the taxa are quarantine pests or hosts of quarantine pests. The data sheets are available to the public for review and comment.

USDA Establishes a New Category in Regulations Governing Nursery Stock Importation; Plants for Planting Not Authorized for Importation Pending Pest Risk Analysis
USDA. Animal and Plant Health Inspection Service.
Prevention is the key to keeping invasive plants out of our country! APHIS is establishing a new category of regulated articles in the regulations governing the importation of plants for planting, commonly known as the Q37 regulations (APHIS-2006-0011). The revision would allow APHIS to maximize protection of U.S. agriculture from foreign pests that could enter this country while minimizing adverse economic and trade impacts. See a recent presentation about the Revision of Quarantine 37 (PDF | 277 KB) for more information.
This action became effective Jun 27, 2011.
