WHY NATIVE GRASSY RESTORATION IS COMPATIBLE WITH MINERAL SANDS EXTRACTON

➢ Presents the opportunity to clearly define vision and goals for returning complex native flora to parts of the post-mined landscape. ➢ Resource companies can develop budgets that properly support the planning and implementation of restoration works. ➢ Projects are conducted over timelines and within rehab footprints that provide realistic opportunities for careful and considered restoration action and adaptive management. ➢ Mineral sands extraction offers a unique potential to carefully manipulate the post-mined landform and soil characteristics so that the seeding/planting surface is appropriate for restoration success (i.e. nutrient characteristics, weed seed banks, water holding capacity). ➢ Mining operations have systems, land access (e.g. for SPAs), equipment, infrastructure and people required to undertake complex and long-term land rehabilitation. ➢ Mining operations are obliged to work in close association with regulators, local agencies and communities ensuring inclusion for the broader community and a common interest and commitment to outcomes.

TEMPERATE GRASSY COMMUNITES

5

At the time of European settlement native grasslands and grassy woodlands were widespread from southern Queensland to Victoria on a footprint now termed ‘the sheep-wheat belt.’ Because of their arable soils and open structure they were prime targets for modified exotic pastures and cropping. They now exist as less than 5% of their

  • riginal extent occurring primarily on

locations not utilized for agriculture.

MAIN COMPONENTS FOR GRASSY RESTORATION

8

  • Proper planning, resourcing and timelines.
  • Access to appropriate species diversity (primarily ground layer).
  • Access to seed in appropriate quantities and quality (wild or SPA).
  • Appropriate site preparation (weeds, soil nutrients, seed bed).
  • Appropriate seeding technology.
  • Appropriate timing of works.
  • Appropriate maintenance regime.

GROWING NATIVE SEED: SEED PRODUCTION

9

  • Seed Production utilizes well-

established horticultural techniques to germinate and grow plants for seed.

  • Many species produce large amounts
  • f seed in production.
  • Numerous genetic individuals can be

grown in small areas.

  • SPAs reduce the impact of repeated

collections on wild populations.

  • SPAs allows a high level of

management control over variables that normally limit plant growth and seed production in the wild.
