Another Sydney water project along The Cooks River, is the restoration of the banks along the Alexandria Canal. Formerly a tributary of the Cooks (Sheas Creek), the canal has been described as one of the most polluted waterways in the southern hemisphere. The project has stabilised the degraded stone walls of the canal, by replacing sandstone but also constructing 'block pools' cut into and between the sandstone blocks, thereby creating habitat for intertidal plants and animals. One of the restored sections is at Tempe Reserve, where I join others for a monthly bird survey. The Reserve is, itself, a restoration project, whereby a former rubbish tip was turned into sports fields, native plant gardens, a saltmarsh and restored bushland.
