Most of the tall trees in the jungle grow huge buttress roots to support themsleves in the shallow, rain leached soil. The buttress roots also help the tree gather nutrients from a wider area.

Even the fairly level trails in Taman Negara are quite muddy and slippery. The steep trails are very difficult, particularly in the 99 degree heat with 99% humidity. At night it cools down to about 70 degrees, but the humidity remains.
