Red List Status -Vulnerable (VU) , assessed in 28/11/2018
Lastreopsis subsericea is an endemic terrestrial fern of New Caledonia, which has a scattered distribution between the south and the north east of Grande Terre. It occurs in dense humid forest on volcano-sedimentary and ultramafic soil between 330 and 1,200 m asl. Known from seven localities, its extent of occurrence (EOO) and area of occupancy (AOO) are 36 and 3,174 km², respectively. The main threat is posed by invasive species (feral pigs (Sus scrofa)) causing habitat degradation. Therefore, L. subsericea is listed as Vulnerable (VU) under criteria B1ab(iii)+B2ab(iii) with a decline of the quality of habitat.
Lastreopsis subsericea is endemic to New Caledonia where it has a discattered distribution across the GrandeTerre.
