Gutian Mountain 24-ha plot was established in 2005. It is a typical mid-subtropical evergreen Broadleaved forest, with the geographical coordinate 29.25°N,118.117°E. The altitude varies from 446.3 m to 714.9 m, slope ranges from 12° to 62°. Annual mean temperature is 15.3℃ and annual mean precipitation is 1963.7mm.

There are 140,700 individuals (DBH ≥ 1 cm) in the plot, belonging to 159 species, 104 genera and 49 families. Trees from FabaceaeLauraceae and Theaceae are dominant in the plot, such as Castanopsis eyrei and Schima superba. Thirty-two species have more than 1000 individuals in the plot, 59 rare species have less than 1 individual per ha.

The vertical structure of the forest is clear: canopy storey, sub-canopy storey and shrub storey. The maximal DBH is 87.4 cm and the mean value of BDH is 5.21 cm in the plot. The DBH size of individuals in the plot follows the distribution of inverse “J” shape.
