再引入

再引入(Reintroduction),或稱為野化放归野放(rewilding),是一種保护生物学策略,指人类經過仔細考慮後將之前并非某地区野生的物種动物植物引入到此地区使其野化进行自然繁衍的一種做法。一般可将圈養栽培的物种重新放歸大自然,或从其他地區幸存的亞種中挑選合適的個體進行野放。這做法除了適合野外已滅絕的物種外,一些瀕危物種也可透過此方法得以回歸大自然。雖然如此,但將已在野外滅絕的物種野放,在實際運作上卻異常困難,即使其生境已得到復原也不例外。其中一個主因是牠們可能已缺乏了應有的求生技能,如一般由其雙親教導的生存技倆,在圈養的環境下經已失去;換句話說,即使該物種的基因得以延續,但其族群間的模因經已失去。[1]

一些再引入成功的例子包括:台灣梅花鹿麋鹿等。
