Cabbage tree creek and its catchment runs from the foothills of Ferny Hills to Sandgate and terminates at Shorncliffe before emptying into Moreton Bay. Cabbage tree creek is known for its intact riparian and the high percentage native vegetation that lines the creek. . Cabbage tree creek is well looked after by its community, and is considered to be very healthy, with a high rating for Abiotic and biotic indicators; although it has its a few low quality zones e.g. the waterway under the Park Collins road.
Abiotic
Abiotic is a scientific term for non living factors that effect the environment. Abiotic and biotic factors combine together to create an eco system. An ecosystem is a community of living and non living things combined together carefully. Abiotic factors include sunlight, temperature, water, turbidity, salinity, pH, nitrides D.O. These factors have a major effect on the biotic factor in the eco system.
Turbidity
Turbidity is the measurement of the clearness of the water. The major determination that can affect the turbidity of the waterways is human manufacturing and consumption. The level of turbidity will affect the biotic factors in the waterway, this can affect the different species and the of macros and micros that are present. Macro and micros have a certain specific sensibility to the clarity of the water, the clearer the water the more highly sensitive macros and micros present. Photosynthesis is affected by the level of turbidity. The turbidity stops the light penetrating the necessary light that is needed for photosynthesis in the plant, which is also, connected the amount of oxygen that is available in the water. The amount of oxygen that is present in the water also is connected to the different species that can live in that waterway. The Overall high turbidity levels can lead to affecting all the orgasming that are present in the waterway.
Dissolved Oxygen
The amount of dissolved oxygen (D.O) is referred
