Landcare - Warburton Project > Stage 1, Revegetation results (February '92)

Picture 1. An aerial view of spirals surrounded by staggered furrows twelve months after they were constructed. Note the vegetation along the staggered furrows and spirals.

Picture 2. Sturt desert pea (clianthus formosus) growing in a ponding bank. Note the plant material growing in the same ponding bank. Much of this is annual vegetation and hays off, gathering as surface trash which provides a seed bed for the germination of perennial plants. A combination of annual and perennial plants is required to sustain a revegetation program.

Picture 3. Plants of old man saltbush (atriplex nummunlaria) growing in another ponding bank. Note the vegetation gathering along the bank which is creating a micro environment suitable for the germination of more plant material. It also helps stabilise the bank. The cracking clay surface in the foreground is an indicator that the ponding bank continues to collect storm water.

Picture 4. Young mulga trees (acacia aneura) which have germinated on the old airstrip between ponding banks. It is not known how old this seed was or how long it was locked in the soil surface before germinating.

Picture 5. A seedling of colony wattle (acacia murrayana) growing on one of the mounds in a spiral. This seed was planted by the Warburton women when the spiral was first constructed 12 months earlier.

Picture 6. Local vegetation becoming established around a spiral. Note how the stronger vegetation is growing along the furrows and mounds where there is a greater concentration of storm water being collected.
