Growing popularity of Cumberland Island National Seashore, which shimmers in the Atlantic on Georgia's largest barrier island, has driven the National Park Service there to craft a plan to, it hopes, better manage that visitation. The agency there has extended the public comment period on their Visitor Use Management Plan through December 30, providing interested parties additional time to review a document that, if approved, significantly evolves the seashore's nearly four-decades old general management plan.

A coalition of conservation groups has moved to intervene in the legal battle over Bears Ears and Grand Staircase-Escalante national monuments in Utah, joining tribal nations that also are challenging two lawsuits that seek to reverse the monuments' boundaries.

Seasonal closures in the Tonquin, Brazeau and À la Pêche caribou ranges of Jasper National Park are in effect until May 15.

The National Park Service needs to pull back its air tour management plans until it can conduct rigorous environmental studies on how park overflights impact wildlife, cliff dwellings, the visitor experience and more.
