Analuddin K, Septiana A, Sharma S, Hagihara A. 2016 . Crown shape dynamics of dense mangrove Kandelia obovata stands in Manko Wetland, Okinawa Island,. The objectives of this study were to elucidate the crown structure dynamics for dense mangrove stands, and to know the crown shape maintenances and its important role for ensuring the stability and vitality the crowded mangrove forest. The growth parameters of K. obovata Shue, Liu & Yong stands, such as tree height H (m), height at the lowest

The results showed that the H L was significantly increased with increasing H, which suggests that the crown changed to be dumpy as the stands grew. However, the C L of young stands increased and then decreased continuously as the stands grew, while the C L of mature stands decreased from 2004 to 2007 and then increased in 2008. Meanwhile, the C L /C W ratio of young stands decreased as the stands grew, while the C L /C W ratio of mature stands decreased and then increased, which imply that dense Kandelia obovata trees might transform their crown shape for reducing of competition for light among trees. Therefore, these results suggested that the crown shape of dense mangrove treesare dynamics as developing stands.
