Seedbanks and Plant Invasions in Victoria’s Grasslands

At the end of 2006, Honours student Aaron Dodd finished his investigation into seed banks and plant invasions of Victoria’s, Western basalt plains grasslands, looking at the effects of landscape on the spatial pattern of the seed banks. He took numerous soil cores from grasslands along a 200 km urban – rural gradient running west from Melbourne and germinated the seeds of these in the glasshouse. His results found that 65 species were present – of these, exotic annual grasses and sedges dominated the composition of the soil seed bank with native species contributing only 13% of the seeds present.
