EXECUTIVE SUMMARY Concerns regarding a lack of native seed supply have been raised within the Australian and global ecological restoration communities for several decades. Recent natural disasters such as the 2019–20 Black Summer bushfires in Australia exacerbate that concern. Many factors can contribute to supply shortages, including failed revegetation projects. Improved guidance on where to source native seed to reduce the possibility of maladaptation to the planting site offers one possible solution. Seed transfer zones (STZs) provide clarification on where seed can be geographically transferred with little disruption of genetic patterns or loss of local adaptation to support better restoration outcomes. The aim of this report is to identify the use of STZs and the level of prescription of seed movement in Australia and internationally, and to report on research or actions that have contributed to or is currently underway that may assist with consensus for and the development of STZs. This report found that prescribed or enforced policy on seed movement and/or the use of STZs in Australia and the United States of America (US) is rarely generated from the top levels of governments or their agencies. Instead, decision making comes from the various offices of the agencies (a bottom up approach, rather than top down) but often with guidance from the respective agency. The level of guidance and enforcement can vary within agencies. It is uncommon for policy on seed sourcing to be mandatory, instead, guidance is often provided. By contrast, in many European countries, there is a top down approach where governments provide clear seed sourcing guidelines (in some cases legislated) and there is a high level of cooperation between countries to achieve major restoration goals and improve current practices. This report is the first to qualify individual organisations’ practice and policies on prescribed native seed movements in Australia.
