“小蓝g钙2023ggy钙2023”天津北大港湿小蓝g钙2023ggy钙2023地白枕鹤种群刷新观测记录

  中新小蓝g钙2023ggy钙2023社天津11月7日电 (记小蓝g钙2023ggy钙2023者 王君妍)记者7日从天津市滨海新区获悉,工作人员6日在巡护天津北大港湿地自然保护区独流减河区域时,发现了中国国家一级重点保护野生动物——白枕鹤的庞大种群。经确认,此次观测到的白枕鹤种群数量高达780余只,大幅超越了2023年3月在七里海湿地观测到的140只的记录,成为天津市白枕鹤观测数量的历史新高。

  白枕鹤是中国国家一级保护动物、全小蓝g钙2023ggy钙2023球易危物种。据资料显示,全球白枕鹤的数量仅5500至6500只,中国境内的分布数量约为3700只。此次在北大港湿地记录到的白枕鹤种群数量,超过全国总数的五分之一。

  据介绍,当前正值秋冬季候鸟迁徙的季节,北大港湿地作为候鸟迁徙的重要通道,过境候鸟数量已达30万余只。其中,中国国家一级保护动物东方白鹳220余只,白枕鹤780余只,卷羽鹈鹕7只;二级保护动物小天鹅1000余只,白琵鹭950余只。预计本月中下旬,将迎来候鸟迁徙的高峰期,届时鸟类数量有望突破40万只大关。

  近年来,天津北大港湿地保护区管理部门开展各项保护措施,湿地生态环境得到了显著改善,鸟类资源不断增长。据统计,保护区内记录到的候鸟种类已从2017年的249种增长至如今的282种,其中中国国家一二级保护动物71种。2024年春天,北大港湿地还首次观测到了中国国家一级保护动物彩鹳的身影。

  天津北大港湿地保护区相关负责人称,为了迎接候鸟迁徙高峰期的到来,管理部门将进一步加大巡查保护力度,设立专业巡护队伍24小时巡查保护管理,利用现代科技手段辅助监测鸟类资源和动态。(完)
