云南发布首个省级物种红色名录 2625种物种受威胁

2017-05-22 11:27:27   央视新闻

5月22日是国际生物多样性日,今天(22日)上午,云南省环保厅联合中科院昆明动物所与植物所,共同对外发布了《云南省生物物种红色名录(2017版)》,这也是我国发布的首个省级生物物种红色名录。

评估范围:

《红色名录》总计评估了11个类群的25451个物种。其中大型真菌和地衣分别为2759种和1067种,高等植物19333种(苔藓植物1912种、蕨类植物1363种、裸子植物115种、被子植物15943种),脊椎动物2285种(鱼类619种、两栖类190种、爬行类211种、鸟类949种、哺乳类316种),另外鱼类有7个亚种按评估标准列为“不予评估”。

评估结果为:

绝灭8种:小叶橐(tuó)吾、干生铃子香、小叶澜沧豆腐柴、单花百合、云南刺果藓、大鳞白鱼、异龙鲤、滇池蝾螈,占评估物种总数的0.03%;

野外绝灭2种:三七、杜仲,占评估物种总数的0.01%;

地区绝灭8种:心叶猴耳环、闭壳柯、白背兀鹫、黑兀鹫、蓝冠噪鹛、斑嘴鹈鹕、双角犀、爪哇犀,占评估物种总数的0.03%;

极危381种:巧家五针松、水松、贡山三尖杉、滇南苏铁、爪哇野牛、豚鹿、虎、林麝、金钱豹、西黑冠长臂猿、双角犀鸟、绿孔雀、赤颈鹤、蟒、凹甲陆龟、斑鳖等,占评估物种总数的1.50%;

濒危847种:红豆杉、多岐苏铁、高黎贡羚牛、马来熊、滇金丝猴、眼镜王蛇等,占评估物种总数的3.33%;

易危1397种:岩羊、小熊猫、黑熊、灰孔雀雉、黑颈鹤、虫草、松茸等,占评估物种总数的5.49%;

近危2441种:赤麂、果子狸、白腹锦鸡等,占评估物种总数的9.59%;

无危:16356种,占评估物种总数64.28%;数据缺乏:2991种,占评估物种总数的11.76%;不宜评估:1013种,占评估物种总数的3.98%;不予评估:7种,占评估物种总数的0.03%。

据专家介绍,《云南省生物物种红色名录(2017版)》是我国发布的首个省级生物物种红色名录。红色名录评估是一项物种灭绝风险评估。通过这一评定,来预警物种的生存危机。本次评估集全国200多位专家学者之力,对云南省已知野生动植物物种进行的一次全面系统的梳理。同时首次将大型真菌和地衣列入生物物种红色名录评估。是迄今为止评估对象最广、信息最全、参与专家人数最多的一次云南省生物物种生存状况评估。该名录将为政府部门相关决策提供重要的科学依据,并对生物多样性保护与管理产生积极的影响。
