Psychotria lycioides is an endemic shrub of New Caledonia, known from Porokoue (Païta) in Grande Terre. An old herbarium specimen (1869) was collected at Ile Nou. It occurs in sclerophyll forest on volcano-sedimentary at an altitudinal range 0-100 m asl. The main threats impacting this species are urbanization with nearby planned developement projects and bushfires. Its area of occupancy (AOO) and extent of occurrence (EOO) being both equal to 8 km², while the species is known to exist at only a single location. Psychotria lycioides is therefore assessed as Critically Endangered (CR) with criteria B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) with a continuing decline of all concerned sub-criteria.

Population


It is known from a single population : Porokoue (Païta).

Habitat


Psychotria lycioides occurs in sclerophyll forest on volcano-sedimentary at an altitudinal range 0-100 m asl.

Threats


The main threats impacting this species are urbanization with nearby planned developement projects and bushfires.

Conservation


Psychotria lycioides is unprotected by legislation and it does not occur in any protected area. This species would benefit from ex-situ and in-situ emergency conservation actions. It is proposed to ensure the follow-up of known sub-populations, to preserve the only viable population on delimited perimeter. It is proposed to integrate this species in restoration projects. It is moreover advised to inform municipal council and the DSCGR (emergency services) on the situation of the species in the concerned area.
