When undertaking land restoration work, and with great regularity, particular species establish only very poorly. More reliable establishment and early, rapid growth could improve the outcome of the restoration project and increase the cost-effectiveness of such projects.  

To obtain good germination and seedling establishment, certain aspects of the abiotic environment need to be determined and acted on. This will involve exploring the characteristics of the study site, and examining how the substrate toxicity, and the light availability and temperature fluctuations at the site, affect the percentage and speed of germination, and early seedling growth. 

Certain aspects of the biotic component (the seed and seedling) also need to be optimised. This involves exploring the viability and quality of the seed lots to be used, their dormancy characteristics, and their abiotic requirements for germination. Different pre-treatments, often used to enhance seed germination, will need to be determined. 

This project aims to determine:

  • the characteristics of the seed that may negatively affect the germination, seedling establishment and early growth of those species
  • the characteristics of the sown community mix that may negatively affect the establishment and growth of that community.
