The silvicultural characteristics of Platanus kerrii Gagnep in Thuong Tien Nature Reserve, Hoa Binh province

Abstract

Platanus kerrii Gagnep has other Vietnamese names such as Ba len, Cho guoi, Tieu huyen. It is a large tree with high scientific value, great economic potential in medicine and conservation values. Our investigation results showed that P. kerrii is distributed at an altitude of 252m to 287m, mainly in tropical humid evergreen closed forests and participates in the canopy layer. The density of the upper tree layer of the forest stand with P. kerrii ranged from 280 trees/ha to 310 trees/ha. Average diameter at breast height had a large fluctuation from 31.1cm to 43.4cm and the average height from 16.5m to 19.8m. P. kerrii had a density of 55 trees/ha to 70 trees/ha and participated in the formula for forming the upper tree layer. The density of regenerated trees in the forest stands ranged from 2.800 trees/ha to 3.280 trees/ha. The quality of regenerated trees in the forest stands was mostly good with the highest rate of 68.3%. P. kerrii  was mainly regenerated by seeds and seedlings were scattered along the banks of streams.
