The researchers studied how Sinojackia rehderiana plants are distributed in a forest in Jiangxi Province. They used different methods to analyze the pattern of distribution and found that the population is mostly made up of young plants. The plants are grouped closely together when they are young, but spread out more as they get older. The growth of seedlings and saplings is limited but there are many of them. The distribution of plants is influenced by factors like competition and the plant's own biology. Overall, the population is not stable at the moment.
