| Research Abstract |
We report the results of the simulated dynamics of a Kandelia obovata (S., L.) Yong forest at Manko wetland on Okinawa Island. Based on the structural and physiological properties of K. obovata, we simulated forest dynamics for 50 years and compared these results to field data sets measuring tree density and mean tree weight. In general, the ratio of the relative growth rate (RGR) to the relative mortality rate (RMR) is around 1.5 in the full-self-thinning phase. On the basis of the simulation results, we hypothesize that the RGR/RMR in the K. obovata stands at Manko wetland is greater than 1.5 in the pre-full-self-thinning phase from 0-6 years, is 1.5 in the full-self thinning phase from 7-27 years, and fluctuates in the post-full-self-thinning phase after 27 years.
