include:
Black Wattle,
infrastructure,
dryland agriculture,
irrigated agriculture,
exposed
soil,
palmiet wetlands and
fynbos
16.3.2.2 Increase in Agriculture
There was an increase in agriculture from 1954 to 2007, almost completely
replacing palmiet wetlands along the entire length of the upper Kromme River
(Fig. 16.13 ). Large, functional palmiet wetlands remain at only one location along
the Kromme, mostly displaced by agriculture. More recently there has been a shift
from pasture crops to orchards by some farmers, especially in the Jagersbos area
(Fig. 16.13 ). Black Wattle has invaded the area not claimed by agriculture.
However by 2007 it had been largely removed from the main channel and
floodplains themselves. Where Black Wattle is cleared by Working for Water, it is
often immediately replaced by agriculture.
