There are a number of ways didymo can be carried from one body of water to another, as has been said. I did research on non-vascular plants, particularly algae, in my last two years of college. There is not much, if anything, that can be done to stop it.
Now...........what about the people who have felt soled boots or waders? I can't afford to go out and buy new boots. What does a person do with the felt sole items? eBay?
It would be nice if someone came up with a way to peel off the felt and replace it with the synthetic stuff (which isn't as good as felt).
The world's funniest jokes:
1. I'm from the government and I'm here to help you.
2. This won't create much paperwork.
