President Trump on Friday issued an executive order requiring Secretary of the Interior Ryan Zinke to "review" all national monument designations made during the last three administrations that are over 100,000 acres. As San Francisco's KPIX reports, among these is Giant Sequoia National Monument, which spans 328,000 acres across Tulare, Kern and Fresno counties — and the Trump administration has apparently recommended shrinking it to 90,000 acres.

Also threatened with being shrunk or removed entirely from federal protection are Berryessa Snow Mountain, Carrizo Plain, Sand to Snow, San Gabriel Mountains, Santa Rosa & San Jacinto Mountains, and Mojave Trails National Monument.

In statements to the press on Friday, Zinke suggested that "in some cases, the designation of the monuments may have resulted in loss of jobs, reduced wages and reduced public access."

But critics and environmentalists have been quick to call this a land grab and potential gift to developers and, in the case of Giant Sequoia National Monument, the logging industry.

According to the order, "Designations [under the Antiquities Act of 1906] should be made in accordance with the requirements and original objectives of the Act and appropriately balance the protection of landmarks, structures, and objects against the appropriate use of Federal lands and the effects on surrounding lands and communities."

KPIX notes that an estimated eight million trees in Giant Sequoia National Monument are dead or dying due to drought-related bark beetle infestation — and as we learned from the temple builders at this year's Burning Man, who were using wood from such dead trees donated by PG&E, wood from non-living trees is not construction grade and therefore may not even be of interest to logging companies.

The station also talks to two members of the Tulare County Board of Supervisors, one of whom supports the idea of shrinking the monument because it will make it easier to manage and thereby less prone to fire. "“Locking [the trees] up in a monument and doing nothing — which is essentially what the Forest Service has done for the past 20-plus years — is not in their best interest,” says Tulare County Supervisor Steve Worthley to KPIX.

The Department of the Interior began taking public comment on national monuments in May. As Zinke said on Friday, "There's no requirement for public input before the designation of a monument and there's no NEPA requirement. Normally, when you do a land use project, we normally NEPA. The Antiquities Act is the exception."

In July, President Trump signed something called the America First Offshore Energy Executive Order which, similar to this latest one, calls for review of national marine sanctuaries like the Greater Farallones National Marine Sanctuary off the Northern California coast, for possible offshore drilling. That sanctuary was expanded under President Obama to include 2,013 miles of coastal waters along the Sonoma and Mendocino coastline.
