原本棲息於美國路易斯安那州、阿拉巴馬州及密西西比州的密西西比林蛙,因人類發展令牠們群體分裂及失去棲息地,現在只有密西西比州南部的哈里遜郡有約100隻的成蛙,美國魚類暨野生動物管理局希望把部分地區(包括一些私人土地)劃設關鍵棲息地來保護這極危物種。此計劃遭土地擁有者反對,因會影響到他們的成本及收益,而法院亦裁定土地擁有者勝出。
the mississippi gopher frog was once found in mississippi, louisiana dm alabama state in the USA, but it can only be found in the southern mississippi now with less than 100 of them; to protect the frog, the US Fish and Wildlife Service would like to designate some area including some private land as critical habitat. the plan was opposed by the landowners as it would affect their costs and benefits, and the supreme court handed a victory to the landowners.
