  由于人类活动、自然气候变化、动物自身等因素,导致中国特有的野生麋鹿种群于19 世纪初叶在本土上灭绝.20 世纪90 年代,通过人类的保护活动,开始将麋鹿在原生地恢复野生种群.野生麋鹿走过了引种扩群、半散养行为再塑、放归自然三个阶段.经过14 年的艰辛努力,人们有计划地实施麋鹿野生放归和自由走出围栏形成野生种群,取得了较好的业绩.

林蛙油是林蛙雌蛙的输卵管,其主要有效成分为蛙醇。近些年来,人们对于食品安全的重视程度越来越高,对于林蛙油内是否含有对人身体有害的物质也越来越重视。其中重金属进入人体要经过较长时间的积累才会显示出毒性,其往往不易被早期察觉,从而更加重了其危害性。

中国大鲵是我国特有的濒危两栖动物。由于具有较高的进化独特性,其在生物多样性保护中的地位非常重要。青海省是中国大鲵分布海拔最高的地区。由于该地区与中国大鲵其它分布地的隔离和环境差异,青海种群很可能具有独特的遗传组分,在分类学和物种保护方面具有重要的研究意义。
