All kinds of equipment, vehicles and materials can transport invasive species to new locations.
But felt is one material that has been the focus of attention for its ability to trap and transport invasive species.
Felt is a material that is used on fishing boots and other river shoes, and can be difficult to clean. Studies have shown that
sediment and invasive species can be trapped in felt.
In some circumstances management agencies have taken measures to restrict the use of felt to prevent invasive species spread. Keep in mind, other materials can also
transport invasive species particularly if they are not clean.
We have provided a number of resources here for you to learn more on the issue of felt and invasive species.

It is important to clean all equipment, including felt soled wading boots, to prevent the spread of invasive species. To learn more about cleaning and steps that you can take, check out this information on Cleaning.
» Felt & Didymo
The mat-forming alga didymo represents a unique problem with felt. Didymo can become easily trapped in felt and transported. To learn more about didymo and special considerations for cleaning felt soled wading boots, take a look at information on Didymo.
