首批白旗兜兰幼苗回归野外

  近期,中国科学院西双版纳热带植物园开展了极小种群白旗兜兰幼苗的野外回归。
 
白旗兜兰的花
 
  白旗兜兰是兰花的一种,具有重要的研究价值和观赏价值,2003年首次在云南普洱被发现有野外分布,这也是目前为止中国唯一已知的白旗兜兰分布点。该白旗兜兰种群位于一个小河沟陡峭的土坡上,仅10余株成年植株。该地人为活动频繁,天然林仅残留一小部分,周围是咖啡等人工种植园,小河已被咖啡加工厂废料污染,生境遭到严重破坏,一场大雨或小河涨水随时可能造成河岸塌方,使这唯一的白旗兜兰种群彻底消失。
 
  2012年,在国家林业局和国家发改委联合印发的《全国极小种群野生植物拯救保护工程规划(2011-2015年)》中,涉及的120种极小种群野生植物中,有兰科植物37种,白旗兜兰也被列为了极小种群物种。
 
  为对白旗兜兰开展抢救性保护,西双版纳植物园濒危植物迁地保护与再引种研究组对白旗兜兰开展了综合保护研究,进行了2年监测,利用人工异交获得种子,通过种子无菌萌发获得大量幼苗;开展原生境土壤分析、伴生植物调查;开展不同季节白旗兜兰菌根真菌多样性研究、传粉生物学研究和种群动态监测等,这些研究将为白旗兜兰的野外回归提供依据。
 
  鉴于白旗兜兰如此稀有却意外发现于普洱地区,说明某种内在生态因子限制了其分布,选择普洱原生境进行野外回归是最保险的做法,但原生境恶劣的生态环境可能会给原有种群及回归种群带来毁灭性打击。为此,除在原生境开展野外回归以外,研究组还选择在和原生境条件相似的地区开展野外回归,建立2个回归种群,并定期对种群进行监测。
 
  准备回归的幼苗
 
  本次回归野外的白旗兜兰幼苗共60株,均为通过种子无菌萌发后,精心养护2年左右的健壮幼苗。60株白旗兜兰幼苗分为2组,一组在普洱原生境范围内选择合适的地点开展回归(reintroduction),另一组根据人工辅助移植(assisted colonization)的理念,在比原生境海拔稍高的地点进行野外移植。此后,将分批次开展野外回归和人工辅助移植,并进行长期的生长情况监测。
 
开展白旗兜兰的回归
 
  对白旗兜兰的抢救性保护,可以使其种质资源和基因遗传资源得以保存,对生物多样性和生态系统保护具有重要的意义。此外,白旗兜兰奇特的花部特征深受人喜爱,一旦野外种群得以恢复和重建,具有极大的园艺观赏价值。同时,通过宣传,公众可以更多地理解兰花等濒危植物的致危因素、保护途径及保护意义,更好地参与到兰科植物保护的过程中。
 
  背景 
 
  极小种群物种白旗兜兰保护生物学研究及其保护教育是山水澜沧江保护基金项目支持的项目。湄公河(澜沧江)是亚洲最重要的跨国水系之一,丰富的生物多样性为流域内七千万人提供了多种生态服务。然而近几十年来,流域内的生物多样性和生态系统服务在气候变化和对自然资源的过度开采下加速丧失。
 
  2014年6月,山水自然保护中心发起“澜沧江保护基金”赠款项目,对有兴趣在澜沧江流域开展生态与文化多样性保护工作的社区、教育或科研机构、民间组织\团体、社会企业提供资助、科学指导、能力建设、交流合作,并组建“澜沧江保护联盟”。“澜沧江守护行动”系列文章,将介绍部分入围项目,展示他们尚未广泛为人所知的守护行动。
