A year following the establishment of the canal blocking, the water level measurement showed that GWL at both locations was not different (Fig. 21.5). Yet, the
canal blocking was not effective to prevent the water from flowing out of the
location. The lowest GWL occurred in September 2018 (>100 cm). According to
Hirano et al. (2012), every 0.1 m lowering water table will release emission of
0.27 μmol m
À2 s
À1 ; ergo, it can be assumed that this area released high carbon
emissions. According to Kusin (2013), this area emitted carbon in 2004 and 2005,
respectively, of 433.62 Æ 10.49 g C m

À1 and 536.49 Æ 193.31 g C

À1 . The water level from July to December 2018 is presented in Fig. 21.5.
In the location #2 (see Fig. 21.1) fire occurred repeatedly in 1997, 2002, 2009,
2014, and 2015. This area was dominated by ferns (Stenochlaena sp., Lygodium sp.,
Polypodium sp., and Pteris sp.) and fast-growing tree species such as tumih
