Saltmarsh is most often associated with coastlines, but the Merri Creek in Campbellfield and Thomastown supports some unusual vegetation dominated by salt-tolerant indigenous species. At Galada Tamboore the Merri Creek gorge has exposed ancient sediments, buried when volcanoes erupted along the Merri several million years ago. Where the lava flows and the more ancient sediments meet, naturally saline spring-water wells from the escarpment and saltmarsh plants have gained a foothold.
In order to conserve these special ecosystems, Friends of Merri Creek has secured a $20,000 Melbourne Water Community Grant. Working with Wurundjeri Land Council and community, the project will map, protect and enhance this rare vegetation, and restore endangered shrublands along the adjoining escarpments. The Friends have contracted MCMC to deliver the project, which will run until June 2020.
