The US Fish and Wildlife Service’s Delisting RecommendationPosted: June 9, 2019
The US Fish and Wildlife Service has published a decision that the ivorybill should be listed as “Presumed Extinct”. As a result, I believe the formal delisting process will begin and will provide details about that process and how to respond when I have more information.
I won’t engage with the document in depth, at this time, but I think it’s a shoddy piece of work, clearly driven by political not scientific considerations. (Even the photo credit at the top of the document is erroneous.)
There’s a good chance this decision, and perhaps many others, would not survive a legal challenge should one be brought. Among the many problems with it, the arbitrary shift to a burden of “conclusive proof” is novel, and it imposes a thoroughly, slippery, circular standard. The existence of a controversy makes it self-evident that conclusive proof has not been obtained. And that’s the authors’ dodge.
My own submission, which argued that the evidence obtained amounts to proof beyond a reasonable doubt, was misleadingly cited to support this “conclusive proof” standard. This intellectually dishonest sleight-of-hand is tantamount to an admission that a new and unscientific standard, higher than beyond a reasonable doubt, is being applied.
I suspect that the Service will end up regretting this decision, and perhaps many others that are part of this massive, politically-driven push for delisting. We will press on. Computer analysis of the audio we collected this spring is gearing up; I’m very excited about that based on my very limited review of a few deployments. While we’ve hit a few technical bumps in the DNA analysis, we expect those to be resolved before too long. We have several samples from both cavities and foraging sign, as well as samples from at least one known Pileated roost. We are also making plans for next year.
