Proposed IUCN conservation category. Based on the collections of fertile material of Cyrtandra fasciata that can be identified with confidence, the EOO of this species is 8792 km 2 and the AOO is 12 km 2, based on a 2 × 2 km grid cell size, under the B criteria (Bachman et al., 2011). The type collection is from Mount Gambuta in the Bogani Nani Wartabone National Park, and the others are from the Mount Sojol and Mount Dako Nature Reserves (UNEP-WCMC & IUCN, 2019). They are from relatively high altitudes in upland and montane forest, which are the least threatened forest types in Sulawesi (Cannon et al., 2007). Because of the relative lack of threat and the protected areas in which the species grows, a category of Least Concern (LC) is given for this species.
