The data comes from the National Field Scientific Observation and Research Station of Forest Ecosystem in Xishuangbanna, Yunnan, China (101°16'E, 21°55'N), located at an altitude of 570 meters. The aggregated data were collected from six permanent plots. Plot 1 ((BNFZH01) is located in the original tropical seasonal rain forest (mature forest), located in the protected area; plot 2 (BNFFZ01) is located in the secondary forest restored after disturbance, in the middle and late stages of succession; plot 3 (BNFZQ02) is located in the secondary forest restored after the disturbance, in the early successional stage (young forest); plot 4 (BNFZQ03) is located in the secondary forest restored after the disturbance, , in the early successional stage (young forest); plot 5 (BNFZQ01) is located in the primary monsoon forest (mature forest); plot 6 (BNFZQ04) is located in the monsoon evergreen broad-leaved secondary forest, in the early succession stage. The area of plot 1 is 100*100 meters, and the area of plot 2 is 50*100 meters, while the area of plots 3-6 is 50*50 meters. To keep a consistent sampling effort, individual-based rarefaction was used to standardize data, that is 1/4 the number of individuals was randomly selected for plot 1, and 1/2 the number of individuals was randomly selected for plot 2. All individuals in the plots were surveyed, and then the number of individuals of each species was calculated for each plot. Plot 1 has data for each year from 1998 to 2006, but plots 2-6 has only data for multiple recent years (different across plots). In the original data, there is also a plot located in a secondary forest, but its area is only 30*30 meters, and thus it is not integrated into this compiled data.
