Case Study - The Gippsland Lake ecosystem

Exercises
1.
a) The Lake victoria was opened in the 1890's to the sea which is making the lake increasingly saline because the lake water is mixing with the sea water.
b) The temperature of the water might be increasing because of global warming.
c) The Thompson Dam was built and it reduces the flow of freshwater. The Dam was made mainly to supply more water to Melbourne.
d) The clearing of the vegetation leaves the animals with no food to eat which leaves them to die. This makes a good place for algal blooms to live.
e) The vegetation has been cleared and lots of water has been drained out leaving a lot of salt with only a small amount of water with it. This leaves the lake to silter up.
