There are currently approximately 1.8 million ha of intact Jarrah forest in Western Australia, about 65% of the total compared to pre-European settlement. Currently, Alcoa mines and rehabilitates 500-600 ha of this forest each year at open-cut mines located between 55 and 130 km south of Perth (pop. 1,500,000), the capital city. Because of the close proximity to the capital, bauxite mining
The Alcoa mining lease covers 712,900 ha of the northern jarrah forest (Gardner and Stoneman, 2003) and the Worsley mining lease covers 1,130,000 ha of jarrah forest and agricultural land. The two...
Jarrah forest soils are lateritic and contain bauxite. This is the ore from which alumina and ultimately aluminium is produced. 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
In this paper, we explored the effects of P-fertilizer on the diversity of the jarrah forest that is restored after bauxite mining. We assessed the restored jarrah forest 13 years after its...
Restoring jarrah forest in southwestern Australia after bauxite mining Andy Seiser . Introduction . Alcoa of Australia Limited is the world’s largest bauxite miner and alumina refiner. This company has mined bauxite in the jarrah forest in western Australia since 1963, and the first restorations were carried out in 1966 (Koch and Ward 1994). The goal of rehabilitation is to establish a “self-sustaining, jarrah
The jarrah forest is an excellent study region for addressing conservation issues because it is a multiple-use forest where logging, mining, water catchment and recreational activities are conducted which leads to conflicts with biodiversity conservation. These issues affecting the jarrah forest are representative of many conservation conflicts globally.
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
In the jarrah forest there are at least 300–400 plant species in vegetation that is typically mined and as many as 163 species per 0.1 ha. Hence, restoring the plant species to post‐mining areas is seen as a priority. Approximately 70% of understorey richness is returned via the direct transfer of fresh topsoil. Additions of provenance‐correct seeds of between 78 and 113 native jarrah

Jarrah (Eucalyptus marginata) naturally grows in low-fertility, gravelly soils in a highly seasonal Mediterranean-type climate. Depending on the conditions, it can grow into a shrub or a mighty...

Jarrah Forest is an interim Australian bioregion located in Western Australia. The Jarrah Forest comprises reserves across the south-west corner of WA and is managed for uses including recreation. There are many small areas of parkland while larger protected areas include the Dryandra Woodland, Lane-Poole Reserve, and the Perup Forest Ecology Centre.

Bauxite mining amongst the Jarrah forest ecosystems of Western Australia has been conducted by ALCOA of Australia limited. ALCOA also have conducted rehabilitation of these mine sites for more than 35years (Grant, 2006). Rehabilitation practices are crucial in forming the characteristics of an ecosystem that is being built on top of greatly disturbed soil, this determines the long term
