Acis nicaeensis is found on the border between France and Italy. The extent of occurrence is less than 5,000 km² and the area of occupancy is less than 20 km². This species has been recorded in two to three localities in Italy and in 17 localities in France. The populations are declining and are severely fragmented due to urbanisation. Further threats are forest plantations, changes of agricultural practice, eutrophication, invasive species, and collection of this plant. It is therefore assessed as Endangered.
|Range Description:||Acis nicaeensis is found in France and in the northwest of Italy's border (Association Tela Botanica 2009, Commission of the European Communities 2009). The geographic range estimated for both countries is 409 km², from which only 1 km² belongs to Italy (Commission of the European Communities 2009). The area of occupancy in France is less than 20 km².|

|Population:||This species has been recorded in two to three localities in Italy (Commission of the European Communities 2009). In France, it occurs in 17 localities with a total of 10,000 individuals estimated. The populations are declining and are severely fragmented due to urbanisation.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:|
This plant grows in the Habitats Directive listed habitats 6220 "Pseudo-steppe with grasses and annuals of the Thero-Brachypodietea" and 5330 "Thermo-Mediterranean and pre-desert scrub" (Commission of the European Communities 2009).
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||
|Major Threat(s):||The main threat to the species' habitat is urbanisation. It is also affected by forest plantings, vegetation change due to changes of agricultural practice, eutrophication, and invasive species. Locally collection of this plant poses a threat.|
This species is listed 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) under the synonym Leucojum nicaeense.
