建德:走过三亿年,幸得新安江滋养

作为中国特有的极度濒危孑遗植物,我身上藏着蕨类植物演化的关键线索。想当年,我们家族也曾 繁盛一时,如今却如同植物界的"大熊猫",纯净水源的减少,让我们的繁衍越发艰难。 幸运的是,在建德市新安江畔,我找到了一片净土。这里的水从新安江水库坝底涌出,常年保持 17℃恒温,水质达到国家一级饮用水标准。湍急的水流不仅保证了高溶氧量,还抑制了藻类泛滥,加上 周围茂密的植被和往来的水鸟,为我们构建了一个良好的生态链。身为最严格的"环境测评师",我的健 康生长,就是这里"无污染"的最佳证明。 然而,我的生存依然充满挑战。我没有种子,生长缓慢,只能依靠根部产生的孢子"传宗接代",传 播途径主要依赖水流和水鸟,且对生存环境要求又高,仅能适应无污染的湿地水塘、河湖浅水带。新安 江水库水位规律性的升降,虽帮我们抑制了其他陆生植物的竞争,但栖息地仍不断被挤压。 30多年前,武汉大学研究团队在新安江畔发现了我,让我从一株无人问津的"野草"变成了备受关注 的"植物明星"。自2019年起,新安江林场承担起了保护我的重任。他们在朱家埠林区为我们打造了一个 60平方米的育苗床;2020年,工作人员在我的原生地采集了993株植株迁至此地进行保护与 ...
