In the 1960s, the State government issued leases for bauxite mining over 800,000 hectares of jarrah forest, and put in place State Agreement Acts which guaranteed easy access to the leaseholders. Mining commenced in the forest in the mid-1960s and expanded rapidly. At first there was a single mine

These issues affecting the jarrah forest are representative of many conservation conflicts globally.

  • Longâ term data suggest jarrahâ forest establishment at

    induced mortality of adult trees has been documented for jarrah forest, but there is limited understanding of its capacity to recover, making it difficult to predict the likelihood of persistent effects. 4. Long-term records of jarrah-forest restoration following bauxite mining are available for the 19-year period between 1992 and 2010. Records include annual data on seedling establishment in restored mine sites for 587
