Post-mining reclamation regulation is complex and requires the resource extraction industry to establish a fully functioning plant community of herbaceous, shrubs, and trees. Most often, the envisioned plant communities are achieved using nursery stock seedlings. A cost-effective alternative method to re-establish plantcommunities is by direct seeding. The successful use of seeds in reclamation sites is constrained by a very poor establishment of sown seeds. Poor seed-to-soil contact, loss of seed due to predation, and seed dormancy are among the main factors limiting seedling emergence and plants establishment success. Seed coating is thepractice of covering single seed or multiple seeds of the same or different species into a single dispersal unitwith active ingredients. The application of this technology to native shrubs and forbs could provide a solution to challenges that reclamation enterprises encounter while applying direct broadcast seeding on reclamationsites. This project aims at assisting a small enterprise in developing methods for multi-seed pellets of shrub andforb and testing their germination and seedling growth. The project will assess the addition of three different filler materials with an organic binder to coat two seed species from two shrubs and two forbs; followed bygermination testing in the lab and greenhouse. The project outcomes will equip nurseries and reclamationenterprises with efficient seed enhancement methodology, which they do not have access to due to'commercial-in-confidence' by the major multinational seed companies. Small- to medium-sized enterprises(SMEs) also lack the capability to conduct scientific experiments and develop their seed coating recipes. It is anticipated that the findings of the study will increase efficiency in the commercial seeding process, improve seed emergence and survival rate, reduce the cost of reclamation, and allow restoration practitioners toestablish plant species diversity in reclamation sites.

开采后的填海法规很复杂，要求资源提取行业建立一个功能齐全的草本，灌木和树木的植物社区。通常，使用托儿所幼苗实现了设想的植物社区。重新建立植物社区的一种经济高效的替代方法是直接播种。在填海地点成功使用种子受到播种种子非常差的限制。种子到土壤接触不良，由于捕食而失去种子以及种子休眠是限制幼苗出现和植物建立成功的主要因素。种子涂层是将同一或不同物种的单个种子或多种种子与活性成分一起覆盖单个或不同物种的多个种子的实践。该技术在本地灌木和FORB中的应用可以解决填海企业在将直接广播种子应用于填海厂时遇到的挑战的解决方案。该项目旨在协助一家小型企业开发用于灌木和Forb多种子颗粒的方法，并测试其发芽和幼苗生长。该项目将与有机粘合剂一起评估三种不同的填充材料，以涂上两个灌木和两个Forbs的种子物种；随后在实验室和温室中进行粘附测试。该项目的结果将为托儿所和再生企业提供有效的种子增强方法，而主要的跨国种子公司由于“信心”而无法获得。中小型企业（SME）也缺乏进行科学实验并开发其种子涂料食谱的能力。预计该研究的结果将提高商业播种过程中的效率，提高种子的出现和存活率，降低填海成本，并允许恢复从业人员在填海场中使用植物物种多样性。
