Rainforest layers
Follow a forest from its crowns to the living ground.
Understanding the environment
A sense of the habitat.
Rainforest is more than its green surface. Crowns, climbing routes, understorey and leaf litter form different environments within the same forest. Sumatra’s protected rainforest landscapes include lowland and montane vegetation; Ujung Kulon offers a lowland example on Java.

Light and branching routes
Crowns
The upper canopy receives the most direct light. Branches, foliage and climbing plants form a three-dimensional network, with shaded spaces below the leaves.
Look for the contrast between exposed crowns and the darker forest beneath.
Conceptual habitat structure, not a measured transect or a species range.
Indonesian examples.
Sumatra’s three World Heritage rainforest parks span substantial elevational variation. Java’s Ujung Kulon preserves a different lowland setting. Neither example represents all forest on its island.
Conservation context
What matters here?
UNESCO identifies road access, agricultural encroachment and illegal logging among pressures on the Sumatran rainforest property. Maintaining forest connections matters alongside the protection of individual patches.
