Juncus emmanuelis

This species is endemic to a small area in the southwestern Iberian Peninsula, with subpopulations scattered in approximately 16 localities. It is assessed as Endangered (EN B2ab(ii,iii,iv)) because it has an Area of Occupancy (AOO) of less than 500 km2 and shows signs of severe fragmentation due to the ongoing transformation of its specific habitat of sandy soils with an impermeable underlayer in temporary pools, as a result of several ongoing major threats associated with intensive agricultural activities. Based on this information, a continuing decline in the AOO, habitat quality and number of subpopulations has been inferred. Additional research and conservation action is needed for this species

Narcissus dubius, Narcisse Douteux

This species is endemic to southern France and eastern Spain. It is assessed as Least Concern because it has a widespread distribution, occurs in several protected areas throughout its range and its population is not expected to significantly decline in the near future. Further studies on the genetic structure of its population and trends in population size at global level are needed

Zannichellia contorta

This species is native to southern, central and eastern Spain, with an old record from the Atlas Mountains in northern Morocco requiring confirmation. The species is very sensitive to eutrophication and deterioration of water quality. The Area of Occupancy (AOO) has been estimated to be less than 500 km2 based on confirmed records and knowledge that its habitat is in continuous decline and at least 40% of the known localities have disappeared, especially in southern Spain. Moreover, an ongoing continuing decline in AOO, habitat quality and number of subpopulations of this species due to the increase in nutrients concentration from waters of the streams where it lives, which stops its growth, has been observed. The same process of habitat deterioration is happening in central and eastern Spain. The population of this species is severely fragmented with more than half of its subpopulations being isolated with no exchange possibilities and suspected to have reached no viable levels. It therefore qualifies to be listed in the category Endangered (EN B2ab(ii,iii,iv)) in the Mediterranean region. Resource and habitat protection and site management are needed. Other recommended conservation measures are ex situ conservation, population and distribution research, and habitat and population monitoring

Juncus fernandez-carvajaliae

This species is endemic to central Spain, where it is currently only known from two sites in the Guadiana River basin located in the western half of Ciudad Real Province. Suitable habitat is frequent around both known sites, and the potential distribution area of this new species could be much larger. However, very little data are available at present regarding its population size, trends or threats and therefore it is assessed as Data Deficient; further research is required
