Protected species -

in Southern Province

Two field expeditions, in 2009 and 2011, to Art Island failed to relocate Pycnandra micrantha. The ultramafic Art Island has a surface area of 53 km² and much of the central part is a flat plateau about 250 m above the sea. Part of the vegetation is heavily damaged by fire and mining prospecting, and is still under threat from fire and potential mining activities. Because the species has not been seen for more than a century, P. micrantha is considered Extinct (EX).

Geographical area


Pycnandra micrantha is an endemic woody plant, known only from the type specimen from Art Island, Belep archipelago, an offshore island in the extreme north of Grande Terre. P. micrantha has not been seen for more than a century,

Population


Population size is unknown.

Habitat


Pycnandra micrantha occurs on ultramafic substrate.

Threats


The main identified threats are linked to habitat damage by uncontrolled bushfires, and mining prospecting.
