What I get out of the bill is this:
If the bill is enacted there will be two lists created: a list of approved non-native species, and a list of banned non-native species.
Any citizen, group, or interested party will be able to voice their opinion about which animals should be approved and which should be banned. The suggestions of animals to be included in either list "must include sufficient scientific and commercial information to allow the Secretary to evaluate whether the proposed nonnative wildlife species is likely to cause economic or environmental harm or harm to other animal species’ or human health."
For a species to be on the approved list there must be proof that the animals "are not harmful to the United States’ economy, the environment, or other animal species’ or human health" or "may be harmful to the United States’ economy, the environment, or other animal species’ or human health, but already are so widespread in the United States that it is clear to the Secretary that any import prohibitions or restrictions would have no practical utility for the United States."
To be included on the list of approved species, the animal is either not a threat, or if it is a threat the problem is already so widespread and out of control that banning the animal would have little to no postive effect.
Basically, we need to prove to the powers that be that our BP's and other snakes of interest do not pose any threat to the environment or economy. If there is enough evidence provided that the animal is not harmful it will be put on the list of approved species, and we will be allowed to keep, breed, and sell them without any issues.
