Floodplain Vegetation
Katfish Reach has a
rich diversity of both terrestrial and aquatic habitats.
Terrestrial habitats, including the floodplain and dune system, range
from forests to woodlands, shrublands, sedgelands, herblands and
grasslands.
On the floodplain these habitats can intermittenly become an aquatic
system for varying periods of time, depending on the size and length of
a flood event, and the elevation of a particular habitat.
227 species of plants have been recorded at Katfish Reach (click here for a full list) of
which 51 are introduced species. In total, 17 species of threatened
plants have been recorded at Katfish Reach (click here for a full list).
As part of the Katfish Reach planning process, 11 vegetation
communities were identified (click

Tree Health surveys
of Katfish Reach was conducted in 2002 as part of the South Australian
Floodplain Vegetation Mapping project.
In 2007, the tree health of Katfish Reach was again surveyed to update
this information due to the impact on the current drought. These
surveys have revealed significant changes in tree health class between
2002 and 2007.
There was a 61% decline in healthy River red gum and a 22% decline in
healthy Black box between 2002 and 2007. The area of dead River red
gum's has increased by 37% and now covers an area of 141.2 hectares on
the site.
