The location #3 of canal blocking establishment also experienced fire in 1997,
2002, 2009, and 2015. The vegetation cover in this location was dominated by ferns
(Stenochlaena sp., Lygodium sp., Polypodium sp., and Pteris sp.) and in some areas,
there were quite dense tree species of tumih (Combretocarpus rotundatus),
gerunggang (Cratoxylum glaucum), and asam-asam (Swintonia sp.) (Fig. 21.7).
