| Structure code | Low Closed Forest |
| Description | Pisonia grandis closed forest to low closed forest. A very sparse to mid-dense shrub layer is occasionally present. The canopy is completely deciduous in the dry season, and consequently the ground is covered with a thick layer of humus and rotting leaves, which excludes most herbs.
