In 2008, the purchase of a new sticker for owners of Maine-registered watercraft was automatically combined with the watercraft registration fee. The sticker, which now reads "Stop Aquatic Hitchhikers -- Preserve Maine Waters" and is physically attached to the Maine watercraft registration, has been required since 2002 for all motorized watercraft on inland waters. Owners of non-Maine registered boats will continue to be required to purchase and affix a separate nonresident sticker. 

National Invasive Species Awareness Week.

National Invasive Species Awareness Week (NISAW) is an international event to raise awareness about invasive species, the threat that they pose, and what can be done to prevent their spread. Representatives from local, state, federal, and regional organizations discuss legislation, policies, and improvements that can be made to prevent and manage invasive species via webinars. Across the country, partners hold public events to educate the public and elected officials about how they can help to stop the spread of invasive species.

Based on years of experience and the latest science, APHIS developed a list of 59 pests and diseases that could pose a significant risk to U.S. food and agriculture resources. The list is not meant to be all-encompassing, but rather focus on the most impactful pests and diseases. USDA's goal remains to keep the U.S. free of these foreign pests and diseases.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is removing a portion of Harris County within the Braeswood area of Houston, Texas, from citrus canker regulations. The successful partnership between APHIS and the Texas Department of Agriculture (TDA) has resulted in a citrus canker-free status in this area since 2016.

On May 20, 2016, APHIS confirmed the positive identification of citrus canker in two adjacent sour orange trees in a city park in the Braeswood area of Houston, in Harris County, Texas. TDA removed and destroyed both positive citrus canker trees. TDA established an intrastate quarantine area for citrus canker that paralleled the federal citrus canker regulatory requirements specified in 7 Code of Federal Regulations (CFR) 301.75. APHIS completed a comprehensive delimiting survey around the area and found no additional citrus trees positive for citrus canker within the survey area. The removal of this quarantine area is reflected on the APHIS website, which also contains a description of all the current federal citrus canker quarantine areas.
