Ok great, so how do we accomplish something? It's my understanding, in wi anyway, the dnr only has authority over fencing.
I don't think fences are the problem, but the existence of insane concentration of animals...
I think the first thing is to examine what can realistically be accomplished. If all we think we know about CWD is accurate, then we a) can't eradicate it, b) can only slow its spread to a very minimal degree and c) can only really control very few factors in the larger picture of CWD. A big problem is that, regardless who oversees enforcement, we are asking a lot from individuals who have far more responsibilities than they have time to accomplish them. Also, we are dealing largely with budget constraints that limit even further the manpower issue. Maybe those statements just sound like "doom-and-gloom", but I prefer approaching things from the real world view. Also, I am very hesitant to ever advocate for more government/laws in any case, so that factors in, as well.
Having said all that, and given societal pressures, here are some thoughts: that stocking density is ridiculous. If people exhibit poor animal husbandry, there needs to be consequences. They make us all look bad, and almost certainly pose a greater risk for disease. Any reported escapes should be investigated. If necessary, corrective actions should be required lest the oprators license be forfeited. Anyone found "cheating the system" should have their license revoked. These actions could get rid of many of the bad apples, and be a benefit to all. Lastly, any farms with CWD positive animals should double fenced if they aren't already, in lieu of indemnity payments, and those animals should become research subjects. We are losing valuable opportunities for study by killing all these animals immediately, and it makes absolutely no sense.
Also, because I have seen it discussed before, operators can't (to my knowledge) insure their animals against CWD losses. Insurance companies know there are too many risks that can't be guarded against. So, we have to remember we are dealing with real people with livelihoods at stake, many of whom are not geting rich from the industry as dipper's relatives have over the years.
Sorry so long, but you asked for it! ;)
