全世界有五分之一的植物物种面临灭绝的危险. Growing concerns for the loss of plant genetic diversity and species’ extinctions, as well as advancing know-how to make successful conservation collections, motivates CPC Network scientists to collect seeds from wild populations and bank them.
The great diversity of plants throughout the world helps define our sense of place and our cultural heritage. Plants have great economic value—providing food, shelter, medicine, and the basis of our livelihoods.
尽管人类已经储存种子几千年了, most of our knowledge about the efficacy of storing seeds derives from plants that have food value. 与此形成鲜明对比的是, 我们对野生物种的了解较少, and there are great differences in seed traits between crops and wild species. Wild species that are rare and endangered pose challenges to seed banking.
自1984年以来, 植物保护中心(CPC), 由世界一流的植物研究机构组成, 一直在进行稀有植物物种保护. By 2018, CPC 参与机构 collectively held over one-third of the globally rare North American plant species (over 1400 taxa) in conservation collections within botanic gardens. 制作和利用我们的珍稀植物收藏, CPC scientists have developed expertise and have experienced many triumphs and challenges. Our research on endangered plants has resulted in peer-reviewed publications covering pillars of plant conservation practice including seed storage behavior, 发芽, 传播, 遗传学, 和恢复. 30多年了, CPC scientists have collaborated to generate CPC Best Practice Guidelines that form the basis of rigorous plant conservation practice worldwide. We understand nuances of making conservation collections from wild habitats; we document the species’ 发芽 and storage requirements; we adhere to genetic considerations while collecting, 维护, and reintroducing the species to the wild; and we have expertise in reintroduction science.
如果我们要抑制植物灭绝, there is an urgent need to involve more people in good conservation practice. Our updated CPC Best Practice Guidelines reflect updated knowledge about best scientific practice. We wish to overcome barriers for botanical institutions seeking to expand their conservation programs by providing the most up-to-date methodology needed to engage in important plant conservation work. The intention of the 中共稀有植物研究院 is to provide an active channel of communication and learning for emerging and seasoned rare plant curators that can lead to widespread understanding and adoption of best practices, as well as discourse when gaps are identified or changes are needed. 最终, we know that preventing plant extinction will require more institutions making high-quality rare plant conservation collections in support of species’ survival in the wild.
中共稀有植物研究院 offers all of us targets we strive to hit in our plant conservation practice. We welcome you to join the conversation and to contribute to the science and to the stories about how practice improves through experience. 请 报名 为我们的 在线社区 利用我们的稀有植物专家网络.
