"Nepenthes rigidifolia" has been evaluated as Critically Endangered on the IUCN Red List. This agrees with an informal assessment carried out in 2006 by Hernawati and Pitra Akhriadi, who also classified the species as Critically Endangered based on the IUCN criteria and using field data collected by the ""Nepenthes" Team" of Andalas University. Since it does not grow within a protected area, "N. rigidifolia" is threatened by habitat loss due to land clearing, land conversion, road broadening, and clearing of road banks. Other threats include forest and shrub fires as well as poaching by plant collectors.
