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(动物或植物)引入到此地区使其野化进行自然繁衍的一種做法。一般可将圈養和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]
