Threadlike filamentous green algae growing in the shallows of Copley Retention Dam. These soft strands consist of a chain of cells, giving a thread-like appearance. Oxygen production as a by-product of underwater photosynthesis creates buoyancy, causing the strands to incline toward the surface.Continue reading “Filamentous Green Algae”

Aroona Sanctuary in the Northern Flinders Ranges not only hosts the Aroona Dam but also overflow and spring waters which provide fertile habitat for a wide variety of birds and other wildlife.
After 3 years of drought, the thriving bird haven of the Copley Retention Dam had almost completely evaporated. Flooding summer rains in the Northern Flinders Ranges replenished the dam overnight.
Throughout the flood / drought cycle, Copley Retention Dam is supporting over 70 recorded bird species, many of which are profiled on the Flinders Ranges Field Naturalists site including birds classified as Rare by the South Australian National Parks and Wildlife Act, such as
- Musk Duck
- Blue-billed Duck
- Australasian Darter
- Elegant Parrot
- Great Crested Grebe.
