The Bidoup Forest Dynamics Plot (BD-FDP) was established in Bidoup - Nui Ba National Park, Lang Biang Plateau of Central Highlands, Lam Dong Province, Vietnam in 2011. The plot lies within a tropical evergreen broad-leaved forest mixed with conifers. The elevation of the plot ranges from 1,516 m to 1,597 m above sea level. The local region has a monsoon climate regime with an annual mean temperature of 17.56°C, mean annual precipitation of 1,750 mm, and humidity of 83.9% - 97.1%.

The first census of the plot (for 20 ha) was completed in 2015 and the second in 2021. The total number of vascular species recorded in the first census is 450 (215 tree species) with the principal tree species being Castanopsis echinocarpa, Lithocarpus coinhensis, Polyosma nhatrangensis, Lithocarpus pierrei, Syzygium rubicundum. The forest basal area is 50 m2ha-1. Including all tree species, there are 201,091 live trees, 232,115 stems with DBH ≥1 cm diameter. Live stem densities mean is 11,605 stems/ha. Plant identification is being checked. The local fauna and fungi were also recorded in the last censuses.

Our research objectives include individual functional traits ecology, the local fauna and fungi.
