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.

The Michigan departments of Natural Resources and Agriculture and Rural Development today announced the addition of beech leaf disease to the state's invasive species watch list. Invasive species on the watch list have been identified as posing an immediate or potential threat to Michigan's economy, environment or human health. These species either have never been confirmed in the wild in Michigan or have a limited known distribution. Beech leaf disease is associated with the microscopic worm Litylenchus crenatae, a nematode that enters and spends the winter in leaf buds, causing damage to leaf tissue on American beech and European and Asian beech species. Infestations result in darkened, thick tissue bands between leaf veins, creating a striped effect on the leaves, leaf distortion and bud mortality. Trees weakened by leaf damage become susceptible to other diseases and can die within six years. Beech leaf disease has not been found in Michigan. The disease was first discovered in Ohio in 2012. Since then, it has been identified in seven eastern states and Ontario.

To minimize the spread of invasive species, interested stakeholders have met to develop voluntary Best Management Practices for Invasive Species. These guidelines will help Wisconsin residents and visitors to limit the likelihood of moving invasive species around.
