Almost forgot; my biggest concern with the situation in the article is that it sounds like water is being hauled to horses that are not in a recognized Horse Management Area (HMA). HMAs are delineated in land use plans with herd objectives and management plans spelled out. From this article this case appears to be outside that process as I would doubt that an area "not officially managed for wild horses " is within a designated HMA.
Yes.
Not only are they watering them, but they have closed the public lands in the area to the public. This is an area that takes 18 points to draw a non-resident 3rd season deer tag.
