热带地区的大规模恢复计划需要大量来自大量物种的高质量、遗传多样性和适合当地的种子。然而，本地种子的稀缺是实现恢复目标的关键制约因素。在本文中，我们分析了三个成功的社区网络，为巴西亚马逊和塞拉多恢复项目提供本地种子和幼苗。此外，我们提出了促进当地参与、法律、技术和商业化问题的方向，以扩大本地种子的市场，以实现高质量和社会公正的恢复。我们认为，有效的社区恢复安排应遵循以下原则：(i)种子生产必须以实际市场需求为基础；（ii）非政府组织和政府组织在支持当地组织、法律要求和销售流程方面发挥关键作用；（iii）应重视当地的生态知识和劳动力，使当地社区能够促进大规模的种子生产；（四）应用研究有助于发展适当的技术和解决技术问题。巴西的案例研究和本文提出的原则可以为世界上许多其他地区扩大恢复生态工作的规模提供帮助，特别是在提高农村社区收入是生物多样性保护和恢复战略的热带国家。
Large-scale restoration programmes in the tropics require large volumes of high quality, genetically diverse and locally adapted seeds from a large number of species. However, scarcity of native seeds is a critical restriction to achieve restoration targets. In this paper, we analyse three successful community-based networks that supply native seeds and seedlings for Brazilian Amazon and Cerrado restoration projects. In addition, we propose directions to promote local participation, legal, technical and commercialisation issues for up-scaling the market of native seeds for restoration with high quality and social justice. We argue that effective community-based restoration arrangements should follow some principles: (i) seed production must be based on real market demand; (ii) non-governmental and governmental organisations have a key role in supporting local organisation, legal requirements and selling processes; (iii) local ecological knowledge and labour should be valued, enabling local communities to promote large-scale seed production; (iv) applied research can help develop appropriate techniques and solve technical issues. The case studies from Brazil and principles presented here can be useful for the up-scaling restoration ecology efforts in many other parts of the world and especially in tropical countries where improving rural community income is a strategy for biodiversity conservation and restoration.
