About NC-PIPPN

In New Caledonia, the NC-PIPPN (New Caledonian Plant Inventories and Permanent Plot Network), initiated by the IRD in 2005, has since compiled 452 forest inventories of different sizes and shapes.

To date, the NC-PIPPN network accumulates nearly 40 ha of inventoried forests, between 10 and 1,300 m in altitude, in a rainfall range between 1 and 4.5 m of rain per year. It contains 66,000 individuals belonging to 98 families, 274 genera and 979 distinct species.

Currently, it groups together different types of plots:

  • 130 round plots of 20 m diameter (DBH>10 cm, area = 0.03 ha)
  • 53 round plots with a radius of 11.28 m (DBH>10 cm, area = 0.04 ha)
  • 21 square plots of 100 x 100 m (DBH>10 cm, area = 1 ha)
  • 18 multiple square plots of 10 x 10 m (DBH>5cm, area = 0.01 to 0.05 ha)

In each of the inventory plots, all trees are numbered in a unique series, their diameter (DBH) is recorded and their scientific name is identified by botanists, either directly in the field or in comparison with the samples stored in the Noumea Herbarium (NOU). The average identification rate at the specific or lower rank of all plots in the NC-PIPPN network is 95%.
