Sections 3(b)(4) through (10) incorporate the subjective, non-scientific standard of likelihood for determining the probability that a species will become established, spread, do harm, or be accompanied by a pathogenic species, parasite species, or free living species
Does likelihood connote some level of probability a specific statistical term or is it merely a subjective conclusion that something might establish, spread, cause harm or be accompanied with parasites? The mere presence of parasites or
other associated organisms is not necessarily problematic. Furthermore, an extremist could argue that any species has some probability of establishing somewhere in the U.S. given the right ecological conditions and propagule pressure. If that probability in scientific risk-based terms presents a negligible risk, how is it assessed under the likelihood doctrine? What methods would be used to determine or score likelihood?
Reading this and remembering the "great snakehead" scare, could anyone tell me about the present situation?..have snakeheads taken over every pond, lake, stream and river in the US?
I goggled it, and lo and behold..while it has apparently established small populations a few places, it has not had the impact on the native wildlife
everyone expected.....and this was supposedly the "ultimate" invasive species!
IMO, this just goes to show how little the so called "experts" really know about this.
A species may have an impact on a local area, but then let that area decide...I mean banning a bird, a fish or any other kind of animal,because it can live outside captivity in FL..OK that MAY be the way to deal with that "problem", but banning the same animals in Alaska, where they would surely parish, makes no sense...
