Project title: Restoration of Banded Ironstone communities in the Midwest - Koolanooka, Blue Hills and Weld Range exploration lines

Dates: 2012 - 2017

Funding: Sinosteel Midwest Corpororation

Location: Koolanooka Mine Site, 400 km NE of Perth

Research themes

  • completion criteria
  • ecohydrology
  • floristic communities
  • infiltration
  • restoration monitoring and targets
  • seed dormancy, ecology, germination and traits
  • seedling emergence
  • soil erosion and properties
  • surface heterogeneity

Project description

This research aims to provide effective ecological restoration of vegetation communities at Koolanooka, Blue Hills and Weld Range, which have been or will be impacted by iron-ore mining. The mine aims to restore 70 percent of the known original species diversity.

A framework of four well-defined logical steps, combining soil and vegetation sciences, has been implemented: 1) plant community and substrate definition, followed by optimising, 2) topsoil, 3) seeds and 4) plants.

We are interested in studying the interactions between seeds and soil to understand the processes and mechanisms behind seedling emergence to improve restoration.
