The blm.gov is saying the cows have been there illegally since 1998 because of the turtle thing.
I don't see how the rancher can be in arrears for lease payments from 1998 to the present since from the blm.gov point of view there was no longer a lease. After 16 years he should be entitled to adverse possession
And the .gov has already spent way way more than any possible value of the back lease payments.
