Case studies Flashcards
What is happening at the Warragamba dam?
There are plans to raise the Warragamba dam wall and create a flood mitigation zone of 14m to mitigate flood effects on Western Sydney.
How will the changes to Warragamba dam affect biophysical interactions?
Environmental flows in the blue mountains would be disrupted and flood, causing damage to areas with heritage value, as well as biodiversity values (e.g. the Regent Honeyeater).
How is the Regent Honeyeater impacted by Human Activity?
The regions occupied by Regent Honeyeaters have also been used as grazing pastures and rotational cropping, which both involve clearance of native vegetation. The agricultural uses in these areas lead to the decrease of native eucalyptus forests, and lack of habitat available for the Regent Honeyeaters.
What is an example of an adaptation to fire?
Eucalyptus trees in Australia have adapted to grow lignotubers that protect the stem from fire damage.
