Kunkeliella psilotoclada is classed as Critically Endangered/Possibly Extinct for it has not been found in the wild since 1983, though it is still believed that new individuals could be hidden in inaccessible areas. Grazing and predation by goats and rabbits limited the expansion of this species and continuously caused its population to disappear.
|Date last seen:||1983|
|Range Description:||Kunkeliella psilotoclada is endemic to the island of Tenerife, Canary Islands, Spain. Its presence was reported in Barranco de Masca (Buord and Lesouëf 2006) but it has not been found since 1983 (Martín Cáceres et al. 2004). It is believed that seeds could be found eventually in the soil seed bank and that some individuals could be hidden in inaccessible sites.|

|Population:||It was last seen in the wild in 1983, when two individuals were found (Martín Cáceres et al. 2004, Buord and Lesouëf 2006). Now it is possibly extinct.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It grows on steep warm and dry crags, where it colonizes ledges and rocky sites, within communities such as Euphorbietum atropurpureae and Echio aculeati-Retametum rhodorhizoides. As accompanying species Paronychia canariensis, Euphorbia obtusifolia, Retama rodorhizoides, Euphorbia atropurpurea, Argyranthemum foeniculaceum, Lotus mascaensis and Kleinia neriifolia have been cited (Martín Cáceres et al. 2004).|
|Major Threat(s):||Grazing and predation by goats and rabbits have been reported as the main threat to the species (Martín Cáceres et al. 2004).|
This species is listed under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). It has been categorized EX in the Spanish Red List (Moreno 2008). It is included as species "En peligro de extinción" in the national catalogue of threatened species and in the catalogue of protected species of the Canary Islands.
The only known population was included in the protected area Parque Rural de Teno (SCI). Plant material is stored in the Jardín Botánico Viera y Clavijo and seeds of viability unchecked are stored in herbarium sheets (OCR) (Martín Cáceres et al. 2004). Individuals should be produced ex situ and the species should be reintroduced to its former distribution, which would need to be fenced. Field work must be developed in order to clarify the presence of more individuals.
