As far a wns...you will not likely keep it from spreading within your area. The idea is to keep it from spreading regions rapidly.
The idea of killing colonies that you find with wns is a bad idea because you may kill certain individuals with the capacity to survive and pass the genes along. Some individuals are making it...
Definitely agree with Dave and David M. on this issue. All the research that has gone on thus far is focused on the goal of finding a solution but in reality timeline wise for many species this is likely to be a case of selective immunity and a major struggle to slowly rebuild the populations from there.
I was in WI more than a decade back now assisting as a govt. guy with CWD head processing. At the time I didn't think much of it and obviously it has been wholeheartedly embraced since then.
Culling or killing depending on which country your from reading this often just results in lots of dead animals with no actual reduction in disease. There are exceptions, but if you look at many of them closely you can find holes in the logic. Even with CWD the studies showed many of the target age/sex of deer were leaving the eradication zone yet most folks glossed over this.
In Europe they've tried to cull badger setts to reduce bovine tb, mostly animal welfare controversy and no reduction has come of this.
Geomyces destructans is a complex issue that is further complicated by the utter lack of basic knowledge of bat populations we have for nearly all other wildlife in our country. The inability to radio track throughout their life history, to find all relevant populations in the hills, forests and caves and the lack of funding in most cases.
I have worked on projects that were several million dollars and know what they can produce. However anything less is just ridiculous and the feds have thus far put forward only $1 million roughly to research and study through congress.
While we have tons of issues in our country that need attention, if we are strictly talking about the limiting factor in this issue, it is boots on the ground and the funding it takes to keep creating ideas and hopeful solutions.
The best thing NWCO's can do in my humble opinion is continue to help the public learn about the benefit of bats, solve bat problems in a healthy balanced way that protects the people and the bats and promote conservation.
In that way we all play a positive role every day we are in the field!
