Fritillaria obliqua ssp. tuntasia is found in the west Kyklades Islands. The extent of occurrence is less than 3,000 km² and the area of occupancy is 28-36 km². The current total population size is certainly no more than 1,000 individuals and all of the known subpopulations include less than 200 individuals which is considered lower than the minimum viable population of 250 individuals. Thus > 50 % of the total area of occupancy of the plant includes small isolated patches with a small number of plants and the population can be considered as severely fragmented. All the subpopulations are threatened by grazing however a population decline is not documented. The species is therefore assessed as Vulnerable, but could potentially qualify for Endangered B1ab(v)+B2ab(v); C2a(i) if the suspected population decline due to grazing was documented.
Fritillaria obliqua ssp. tuntasia is found in the west Kyklades Islands (Kythnos, Piperi islet off Kythnos, Gyaros, Serifos and Folegandros). However, the presence of the plant on Folegandros and Kythnos requires confirmation. The plant is also reported from Kea but it may have been confused with Fritillaria graeca.
The extent of occurrence of the subspecies is 1,000-3,000 km² if the sea between all the islands is included and depending on whether the unconfirmed references on Piperi and Folegandros are included; the islands themselves have a total area of 191–223 km². The area of occupancy is 28-36 km², depending on whether the unconfirmed references on Piperi and Folegandros are included (2x2 km grid).

|Population:||Fritillaria obliqua ssp. tuntasia has been reported at the following locations:|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Fritillaria obliqua ssp. tuntasia is found in rocky and stony places with phrygana or thin shrub, on various substrates (e.g. limestone, granite) but mainly on schist.|
|Major Threat(s):||Grazing, which causes a decline in the sexual reproduction of the plant, is a threat at all the locations of the subspecies tuntasia.|
It is listed under the name Fritillaria tuntasia in Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention).
Fritillaria obliqua ssp. tuntasia is protected in Greece by Presidential Decree 67/81. The location Kastro tis Orias (Kythnos) is included in the Natura 2000 site GR422010 and the locations at central Serifos are included in the Natura 2000 site GR422009. The subspecies is included in the Red Data Book (Phitos et al. 2009).
