RonG, Welcome to the board.

As much as I hate to say it....keep a camera with you since you have had obvious problems and document everything!! Yep, I know its a pain in the butt but...you almost have to do it. The last time I checked the federal regs it was legal to take care of a situation if you witnessed wolves attacking your livestock. Have it on film too! Then, there is NO way that your allegations could be refuted by anyone, even the feds JMO. As much as I do love wolves....I have friends that ranch out West myself and understand the situation well as they have been through the same situation. They documented and were reimbursed their loss.
It seems as if people see it in black and white with no grey inbetween........and when it comes to the Wolf there are many grey areas of uncertainty in the eyes of legalities. Good Luck!

EKM, You are correct that it has unfortunately turned into a rather "crappy" situation to say the least.
