Centaurea niederi is endemic to Greece and restricted to the western part of the mainland where it is found in three localities. The area of occupancy is 20 km² and the extent of occurrence is less than 5,000 km². The total population has approximately 1,700 individuals of which the biggest subpopulation hosts 1,000. Collection, road expansions and quarries are potential threats for the species. However, the current population trend is unknown, there are no indications for a continuous population decline, and a part of its range lies within a protected area. It is therefore assessed as Vulnerable.
|Range Description:||Centaurea niederi is endemic to Greece and restricted to the western part of the mainland where it is found in three localities. Two are in western Sterea Ellas (Kleisoura Gorge and near the village of Fraxos) and one in the northwest Peloponnese (Mavro Vouno near Araxos) (Phitos and Kamari in: Phitos et al. 2009). The area of occupancy is 20 km² and the extent of occurrence is less than 5,000 km² (Commission of the European Communities 2009). |

|Population:||The total population has approximately 1,700 individuals of which 1,000 are in Kleisoura Gorge, 150-200 near Fraxos and 500 in Mavro Vouno (Phitos and Kamari in: Phitos et al. 2009).|
The population trend is unknown (Commission of the European Communities 2009) and there is no indication of a continuous decline in the number of mature individuals.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This plant grows on vertical limestone rocks from above sea level to 150 m (Phitos and Kamari in: Phitos et al. 2009).|
|Use and Trade:||This species is collected by botanists although levels of harvest are not known.|
|Major Threat(s):||As the species grows in coastal areas and along roads, collection by amateur and professional botanists could be a threat. Furthermore road expansions and quarries in the area of Araxos are potential threats for the species (Phitos and Kamari in: Phitos et al. 2009).|
Centaurea niederi is listed as priority species on Annex II of the Habitats Directive and under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention).
This plant is listed in the National Red Data Book as Vulnerable (VU) B1ab(ii,iii,iv)+2ab(ii,iii,iv) (Phitos and Kamari in: Phitos et al. 2009) and is protected by the Presidential Decree 67/81. A part of the populations falls within the borders of Natura 2000 sites. There are no protection measures taken so far but the following ones are suggested:
