Numerous scientists have talked of the necessity to increase and preserve biodiversity because it provides humans with services such as clean air, water, fibre, food and medicines (Ref: Australia's Biodiversity Conservation Strategy - click here)
Creeks and river courses are priority targets in this area because of the urgent need to improve water quality to the Great Barrier Reef World Heritage Area. Australia’s signatory obligations is to protect and manage it. Rivers have a dynamic nature so where the vegetated riparian (the land next to water) is altered it causes many problems. Intact riparian helps improve water quality by forming a barrier from polluting forces and stabilising the banks from erosion, providing shade, shelter for wildlife and increasing food sources for aquatic wildlife.
