Fallen Oreades – Swamp Resilience

A very large Gully Oreades Roost tree (Eucalyptus oreades) came down in April during a windstorm. Council’s Natural Area Operations team made the area safe and cut the old tree up into usable pieces for use in Middle and Top Swamp for erosion control, water retention, habitat and organic matter.

Some of you may remember when Kirsten Cowley came and talked to Garguree about her PhD which involves assessing the physical attributes of upland swamps, such as water quality, carbon sequestration potential and sedimentology and how these attributes change along a geomorphic degradation spectrum. (To read more see link below).

The fallen Oreades are used to form check dams across the contour lines to slow down water movement across the swamp. These sediment control measures will contribute to the health and resilience of the swamps in ways that were outlined by Kirsten in her talk (attached below a short explanation of her research methods) by placing more organic matter into the systems and slowing the flow of water.
