Size/Abundance

Direct impact to approximately 3.7ha of habitat in the Headland assessment area.

Direct impact to a total of approximately 4.8ha of habitat in the three assessment areas

Duration

Loss of habitat within footprint of proposed development would be permanent.

 

Indirect construction phase disturbance would last for duration of construction phase.

 

Very minor, permanent increase in disturbance during operational phase.
