Biologists theorize that giant salvinia is spread from lake to lake by boat trailers. As a boat is pulled out of water infested with salvinia, the plant can stick to the sides of a boat or trailer. Elder says all it takes is one leaf to survive the trip to the next lake and a new infestation is started.

Biologists call it the world’s worst weed. The plant has the uncanny ability to reproduce itself rapidly. One plant can become 60 million in less than two months. A handful today will cover more than 40 acres in just a few weeks time.

One of the problems is that most boat launching areas do not provide any kind of wash off area for boats. Most of us will wash our boat or tubes when we get home but who says that crap won't get into the streams from there.

the biggest problem is education. i've run into fisherpeople completely unaware of NZMS in waters they were fishing. and i'm guilty too, having never heard of salvinia.

Is Salvinia something that is indigenous to the north or is it in the south also? I live in Florida and I never heard of it.
