Invasive Species Resources

Operators of watercraft not registered in Washington State, seaplanes, and commercial transporters of specified vessel types must purchase aquatic invasive species (AIS) prevention permits to help prevent the spread of AIS in Washington. AIS prevention permits are valid for one year and can be purchased online (under the "Other" Product Categories tab) or from any of the department's authorized license dealers. When purchasing online, you may select a preferred activation date. The permit will be valid for one year from that date.

Ohio Department of Agriculture (ODA) today announced the United States Department of Agriculture's National Veterinary Services Laboratory in Ames, Iowa, has confirmed that an exotic tick, known as the Asian longhorned tick, has been found in Gallia County. "Due to the nature of this pest, the female ticks can reproduce without a male, so it only takes one tick to create an established population in a new location," said ODA State Veterinarian Dr. Tony Forshey. "This pest is especially fatal to livestock, so producers should practice preventative measures and be on the lookout for this new threat."

The Asian longhorned tick is an exotic East Asian tick that is known as a serious pest to livestock. U.S. Department of Agriculture first confirmed the presence of this tick in the U.S. in New Jersey in 2017. In the United States, the tick has been found in or near counties with large horse, cattle, and sheep populations. To protect against infestations, farmers should check their livestock for ticks regularly. If producers spot unusual looking ticks or large infestations, report this to your local veterinarian or ODA's Division of Animal Health at 614-728-6220.
