Recovery of Logged Tropical Montane Rainforests as Potential Habitats for Hainan Gibbon

As the world’s rarest ape, main threat facing Hainan gibbon (Nomascus hainanus) is habitat degradation and loss caused by human disturbances. The insufficient area continuous disturbance in most of existing habitats can hardly maintain future recovery development population. A large secondary tropical montane rainforest was retained Bawangling National Nature Reserve after disturbance. Therefore, it great significance to study these forests for protection restoration habitat. To explore rainforests different disturbances, whether they have potential serve as gibbon, we calculated four dynamic indexes (including recruitment rate, mortality/loss relative growth rate turnover rate) abundance basal total community food plants based on data from two censuses recovered nearly 45 years disturbances (clear-cutting selective-logging) old-growth forest rainforest. results are follows: (1) There were no significant differences rates, mortality rates between clear-cutting forests, selectively logged forests. (2) Abundance, species small (1 < DBH ? 10 cm) medium (10 30 disturbed higher, while those (DBH ? lower than (3) For common occurring all three kinds communities, trees higher that forest. Our research demonstrates lack key limiting factor mountain at present. However, has transform into suitable through targeted management due high small- medium-sized plants.
