État de la populationExpert
The highly disjunct distribution, on both a local and a regional scale, suggests that all species of Nothofagus were either previously more widespread, or that isolated populations have been mobile following climatic shifts; although N. baumanniae along with N. discoidea may never have extended far beyond their present geographic range (Veblen et al. 1996). Recent pollen analysis suggests a much more widespread distribution of the genus; which suggests that climate change has been a long contributing factor to the decreasing population of the species however this species' range is not believed to have been any more extensive in the past so historical population decline is not assumed.

Description complète des menacesExpert

Considering the little literature available regarding threats to Nothofagus species specifically, it seems prevalent that all three pressures: the minor threat of agricultural development and the major threats of climate change and nickel mining which are having a devastating effect on much of New Caledonia’s flora. Of these three threats fire is having the greatest impact on the species due to its occurrence at higher altitudes.

There are concerns of a reduced regeneration potential for Nothofagus forests within New Caledonia especially following fires where rainforest is often replaced by xerophytic woodland or maquis. As there is growing incidence of fire on the island this could become a greater threat to the species as its native habitat is lost. Nothofagus has not been known to recently invade these new habitats (Veblen et al. 1996) however at some sites seedlings are present. Widespread disturbance is needed alongside suitable growth conditions to encourage significant regeneration of Nothofagus species.

Habitats préférentiels (classification IUCN)

  • 1_6Forest - Subtropical/Tropical Moist Lowland
Mesures de conservation recommandéesExpert

The southern subpopulation seems to be within the protected reserve of Botanique du Mont Mou and Mount Kouakoué. According to BGCI Plant Search (BGCI 2017), there is no ex situ collections of this species. It is recommended that seed collections are made for the species.
