You nor I Know what ESRD is claiming to be the concern. Perhaps your guess will prove correct, but until ESRD speaks up, you are just guessing.
As a suggestion, read up on Festa Bianchet, Pelettier, Hoggs, Hubbs, and Jorgenson on ram physiology, phenology, mortality, breeding success, hunting induced genetic selection. ...
This group of researchers have been claiming trophy hunting induced genetic harm as a Proven concern requiring a dramatic reduction in ram harvest. "Coincidentally", this is the same group that compiled the historical ram data being used by ESRD.
Funny thing has happened with this data. As it is in the hands of contracted researchers there are legal restrictions on access to this information.
Wanna guess when the data will be released? Do you think it will be released during consultation with the AGMAG meetings?
How about August 14, 2015 ?
Wouldn't that be convenient for the anti-trophy hunting gang to push their aganda through without having to let anyone vet the research?
Have a look. Here is the data, locked up for another year....
