That's despite what the O-bots at Think Progress are trying to claim, where the page header for the link (unless it's later changed) says "Obama creates new national monument."
In reality, he added 2.5 square miles on onshore lands to a previously islands-only national monument that ranged the entire length of the California coast. Don't get me wrong; Point Arena is a nice addition. But, this is NOT all that. And, it's a monument created by Clinton in 2000.
Let's also note that BLM-based and Forest Service-based national monuments are of generally low level in terms of visitor outreach and promotion as natural areas, when compared to National Park Service system national monuments.
That said, that problem traces back to Clinton. Because he wouldn't ask Congress to give the NPS more funding, and it's already underfunded, he created these monuments without shifting them to the better oversight of the NPS. Obama's doing the same thing. (Bush did it, too.)
(And, at least one possible O-bot there has, in replying to my comment, already misinterpreted what I said.)
Besides, we've heard bupkis so far from this administration's plans for the NPS's centennial. Whatever is done will likely be drenched with corporate sponsorship. And I'm definitely concerned about that. I will boycott any centennial event that is, in my opinion, too corporate-heavy.
On the main issue at hand, I don't want any new national monuments created that aren't part of the NPS. And I don't want any new NPS national monuments created until the Park Service gets more money.
