记者注意到，早在2021年，北京麋鹿生态实验中心的麋鹿就曾被引入位于延庆区的北京野鸭湖湿地公 园，负责对湿地优势生长的植物进行生物"调节"，它们可以吃掉过多的湿地芦苇，控制水体富营养化的 情况。 9月23日，北京市园林绿化局在顺义汉石桥湿地自然保护区举办第十三个"北京湿地日"主题宣传活动，6 只麋鹿来到美丽的汉石桥湿地，开展野化训练。继北京野鸭湖湿地公园后，麋鹿又一次从大兴来到"新 家"野化训练，标志着北京在濒危物种保护、湿地生态修复和生物多样性提升方面取得新进展。 6只麋鹿来到"新家"汉石桥湿地。北京麋鹿生态实验中心提供 更多麋鹿有望被引到北京其他湿地 当天上午，来自北京麋鹿生态实验中心的六只麋鹿来到水草丰美的汉石桥湿地，随着车厢打开，它们先 是警惕地观察四周环境，便头也不回地跑向密林深处。 "它们3-6岁、身体状况良好且佩戴卫星追踪项圈，将开展野化训练，探索湿地生物多样性保护提升路 径。"北京麋鹿生态实验中心麋鹿保护研究室副主任郭青云说，六只麋鹿有三只雄鹿、三只雌鹿，拉开 年龄梯度是确保它们中既有"青年鹿"，也有明年即可交配的"成年鹿"。每年7、8月是麋鹿的发情期，此 次从大兴"搬家"到顺义的雌性麋鹿中， ...
