Project description: In June 2008, the Pilbara Seed Science and Resource Management Project ('Pilbara Seed Atlas') commenced between BGPA and BHP Billiton Iron Ore. The objectives of the project are to provide leading-practice seed science detailing methods of seed collection, cleaning and post-harvest handling, and an inventory of seed viability and an analysis of key seed germination characteristics to enable the efficient use of seeds in rehabilitation.

The underlying principle in this project is that knowledge of seed collection, handling and germination optimisation are complex when dealing with biodiverse plant communities as found in the Pilbara region. Past failures in the effective use of seed can be linked to the need to develop site-specific, bioregional approaches to seed utilisation that address the core issues of timing of collection, quality of seed, viability of seed and dormancy release. This study is the first attempt to derive robust, science-based criteria for establishing a sound and sustainable seed-based rehabilitation program for the Pilbara region.

Key areas of research are currently focused on:

  1. Identification of the phenology of flowering, fruit set and seed maturation and associated seed collection and cleaning techniques.

  2. Analysis of the purity and viability of collected seeds, and determination of seed germination and dormancy characteristics to define the available seed resource.

  3. Development of reliable methods for germination of dormant seeds to utilise the seed resource.

  4. Optimisation of seed storage methods to protect the seed resource.

  5. Application of seed enhancement technology to improve seedling establishment and deliver the rehabilitation potential of the seed resource.
