Least Concern (LC) , assessed in 28/11/2018Dendroconche varians is an epiphytic fern growing on tree's trunks, endemic of New Caledonia, where it is widely distributed across Grande Terre, from Nakada in the south to Mandjelia in the northeast. This species is locally common and abondant and it is found in dense humid forest from 600 to 1,000 m asl. With an extent of occurrence (EOO) equal to 1,870 km² and an area of occupancy (AOO) of 32 km², D. varians does not seem threatened and therefore is assessed as Least Concern (LC).
