Closures in Washington State?

[Dave-Trinity-Farms]

Got an email from Ryan and this is what he had to say.

Hi Dave, these goats have been doing great, tons of fun..I talked with joe and he said he talked with Dave Waldron who is the outfitter in the wenaha west unit...he's the guy who told joe that pack goats were not allowed down there...

Can they just close off a unit without a reason or going through the proper channels? Im going to start doing some research on that area.
