  abstract = {{A}ims: {T}o describe the structural and floristic diversity of {N}ew {C}aledonian mixed tropical rain forest and investigate its environmental determinants. {L}ocation: {N}ew {C}aledonia ({SW} {P}acific), a biodiversity hotspot. {M}ethods: {S}tructural (stem density, basal area) and floristic characteristics (composition, species richness and dissimilarity) were investigated along environmental gradients (elevation, rainfall and slope) on different substrates (ultramafic and non-ultramafic) through the {N}ew {C}aledonian {P}lant {I}nventory and {P}ermanent {P}lots {N}etwork ({NC}-{PIPPN}, 201 plots each measuring 20 m x 20 m). {R}esults: {A} total of 28,640 trees ({DBH} >= 5 cm) belonging to 749 species, 240 genera and 92 families were inventoried in the {NC}-{PIPPN}. {T}he {N}ew {C}aledonian mixed rain forest studied was characterized as having high stem density, basal area and species richness, and many small stems (60% of the trees <10 cm {DBH} and almost a quarter of species did not exceed this threshold). {M}ore than one-third of the species were rare (i.e. inventoried in less than three plots or represented by fewer than three individuals) in the plot network and floristic dissimilarity was high ({B}ray-{C}urtis index >0.70). {T}he presence of ultramafic ({UM}) and non-ultramafic substrates (non-{UM}) combined with altitudinal and rainfall gradients were the main drivers of floristic dissimilarity, whereas the effect of geographic distance between the plots was surprisingly low. {F}loristic dissimilarity was very high between {UM} and non-{UM} substrates from species up to family level. {A}bout 75% of the species occurred on a single substrate type. {T}he mixed rain forest on {UM} and non-{UM} substrates differed in floristic composition but not in structure. {C}onclusions: {NC}-{PIPPN} proved to be an effective tool for investigating the woody species richness of {N}ew {C}aledonia as containing ca. 46% of its non-herbaceous species. {H}owever, the network's design, and more specifically its small plots, restricts its capacity to capture beta diversity and forest structure. {H}igh species richness and floristic dissimilarity confirm that {N}ew {C}aledonian mixed rain forest is exceptionally rich.},
