3.1. The Rafflesia track
The track travelled as far as 872 m. About 2 h from starting point (Fig. 2). The starting point is from pantai
kupu-kupu which is not far from the resort. It is located on the Buluh River that flows into the Batang Serangan
River. In this track, there is also a tiered waterfall which by local community is called as Kenangan Waterfall and
Lao Anak Pakam Waterfall. There was a rafflesia garden on this track, so this track is named as Rafflesia (Fig. 3).
There were five forest plants that were found in Rafflesia Track, namely: durian hutan, malutua, semantok, jamur
kayu, and meranti buaya. The list of forest plants that can be found on these tracks can be seen in Table 1.
