In his 2009 book, "Pitcher Plants of the Old World", Stewart McPherson writes that "N. peltata" is "not currently threatened" owing to its extensive populations on Mount Hamiguitan and the fact that visitors are only permitted to climb the mountain with the assistance of a guide. The future of wild populations of "N. peltata" will be further secured if provincial officials of Davao Oriental are successful in their bid to gain recognition of Mount Hamiguitan as a UNESCO World Heritage Site.
