Fig. 16.16 Snapshots capturing the change in extent and surrounding land-use of valuable
palmiet peat wetlands due to an increase in agriculture and invasion of Black Wattle from 1954 to
2007. These wetlands occur on Krugersland Farm and are currently the last existing wetlands in
the Kromme River. Important land-use changes include: palmiet wetlands, Black Wattle,

dryland agriculture, irrigated agriculture, and fynbos

16.3.2.5 Geomorphological Changes: Changes in Channel Length

The total channel length has increased from 1954 to 2007 (Fig. 16.20 ). Very little
change in the total channel length occurred between 1954 and 1986 with the most
marked changes happening before and after this period. This implies that the river
channel has become more meandering with time, which may be a result in
decreased channel stability brought about by the invasion of Black Wattle.
