Australia – Developing a Biorich Demonstration site at Lal Lal (Australia), an Imerys mining site
The Lal Lal quarry in Victoria, Australia is being transformed into a biorich plantation that will set a new benchmark.
Developed in cooperation with Ballarat Region Treegrowers, the project covers 10 hectares of marshy land around the Imerys Minerals Australia mine. In line with methods outlined in the book "Recreating the Country" by Stephen Murphy, the aim is to design sustainable ecosystems that are rich in native flora and fauna species. A plantation sustainability index was defined, based on diversity, structure, species survival and location. Most of the plant species are native and grown from local seed.
- A varied mix of local flowering trees will be planted, comprised of 15 families, 20 genera and 40 species;
- These include five eucalyptus and seven acacia varieties, all native, which will foster development of wild fauna;
- Several native forest species will be planted on the southern part of the site to show that biorich plantations can produce high-quality logs and useful products for agriculture.
Over Fifty people, including several Imerys employees, volunteered for the two planting phases in late 2010 and mid 2011. More than 9,000 plants in the program are in place and the site is being monitored continuously.
Imerys will manage and maintain the site when planting is completed. The program will show how farming activities, forestry and rehabilitation can mix. The aim is to prove that biodiversity can be improved, vegetation protected and water quality improved, while developing local forest-growing and farming.
