Araucaria species profiles
Worldwide the genus contains 19
extant species variously arranged into 2-4 sections
depending on the taxonomic treatment applied.
The 13 New Caledonian Araucaria species
form a closely related assemblage all belonging
to one section of the genus (Eutacta).
The New Caledonian species occur in habitats and
soil types ranging from coastal to mountain top,
and from calcareous substrates to ultramafic soils.
They are all monoecious trees and occur in a range
of population sizes and densities.
Whilst there are clear-cut differences
between some of the species, for others it is
more difficult to define species boundaries and
there can be real difficulties in determining
the identity of some populations. This presents
problems for conservation as determining the range
and abundance of a species first requires that
it can be identified and surveyed accurately.
Below is a series of maps
and links to photographs of the different species.
These represent a combination of our own field
observations and those of our collaborators, but
the primary source of the maps is De Laubenfels's
account in the Flora of New Caledonia. As our
work progresses we will update these distribution
maps as our understanding of species limits evolves.
See also the Araucaria Biodiversity Database
(in the Resources side bar) for further information
on these species.
