Description
Stand structure and dynamics of Betula alnoides forests in the Caiyanghe Nature Reserve located in Yunnan Province, China, were studied. These were secondary forests distributed over the subtropical zone; they were established after human activities led to the destruction of evergreen broad-leaved forests. A total of 10 plots were established in stands that were aged 10-40 years and were at different stages of development i.e., from young, small-sized stands to fairly mature stands. The height and DBH (diameter at breast height) of stems≧3cm in DBH were recorded. The number of stems per hectare of B. alnoides showed a strong negative correlation with the maximum DBH of the species. Juveniles (<3cm in DBH) of B. alnoides were not found in any of the stands. DBH- and height-class distributions of the mature stands showed that regeneration of B. alnoides was discontinuous. More than 89.7% of B. alnoides stems found in the mature stands were canopy trees. On the basis of these results, it was concluded that B. alnoides is a typical shade-intolerant pioneer species that regenerates in sites with ample sunlight. In addition, the present study suggested that B. alnoides grows to a height of 25m and 40m within 20 years and 40 years, respectively.
