I think "Another Guest" was expressing a genuine opinion rather than creating a devil's advocate argument just for the sake of controversy (a.k.a. trolling). When making an evaluation it helps if a person identifies his/her self instead of posting anonymously.
I don't know the legal status of that area. But if it's really important that people not go there, it seems silly to rely on silence and ambiguity, rather than just closing the area and enforcing it. Even without 100% enforcement (due to lack of resources), I think many hikers would respect these issues if the State Park said it's closed because of such-and-such. It would also be considered inappropriate to post photos and trip reports on message boards. There is another area that is obviously a foot-traffic issue, and we respect that here on this forum.
Here's a bigger issue: all the trash in Long Valley that appears during the springtime melt-out. I think there should be a big sign that says "Littering: $500 Fine" (or whatever the amount is) and then the rangers start citing people or making them pick it up if they want to avoid the fine. But that won't happen because it's not tourist-friendly and may slightly hurt the Palm Springs economy by offending people.
Regarding Skyline and bighorn sheep, even BLM admits that the evidence against hikers is weak:

In addition, Hamilton et al. (1982) found that sheep avoided using areas while
humans were present but were not permanently displaced by hikers. Bighorn behavior was
modified to avoid human interactions at salt licks or waterholes, visiting each earlier or later in
the day when humans were not present (Campbell and Remington 1981, Hamilton et al. 1982).
Skyline is also known for *not* having water.
The real issues are land development, oleander in people's yards, and vehicle traffic. Hikers are really just the "scapegoat," and a distraction from other issues that are tied to business interests. Common sense says that if the Cahuilla Indians walked all over this mountain and hunted the bighorn for food....yet the population thrived prior to Europeans showing up....then something else must be more significant than the effects of hiking. Blaming hikers seems like a political tactic. After all, many Sierra Club members like to hike, and nobody wants to appear hypocritical, right?
Here's a better solution: set up cameras and fine reckless drivers on Highway 74. The problem: fast driving is a part of Southern California culture. Or make people fence their Oleander if it's exposed to the open desert. Or...god forbid...stop developing more land and build taller buildings instead. Or if people stopped having so many children, a lot of issues would be solved. But then, that's not very PC to talk about.
