Lactuca singularis is assessed as Vulnerable because its area of occupancy (AOO) is less than 2,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat and in in the number of mature individuals. As it grows at a high altitude it is particularly vulnerable to the effects of climate change.
|Range Description:||L. singularis is endemic to southeast Spain (Lebeda et al. 2004). Its area of occupancy (AOO) is less than 2,000 km2.|
Native:Spain (Spain (mainland))

|Habitat and Ecology:||It is found on rocky slopes on high mountains.|
|Use and Trade:||L. singularis is a wild relative of and potential gene donor to lettuce, L. sativa.|
|Major Threat(s):||As this species grows at a high altitude, it is likely to be particularly affected by climate change.|
L. singularis is protected by law in Andalucia and is listed as Vulnerable (VU) in the 2008 Spanish Red List (Moreno 2008). It occurs in protected areas.
No germplasm accessions of L. singularis are reported by EURISCO to be held in European genebanks (EURISCO Catalogue 2010). Germplasm collection and duplicated ex situ storage is a priority for this species.
