カンムリイモリ（Triturus cristatus）はIUCNレッドリストで準絶滅危惧（NT）に分類される。絶滅危惧基準に近く、保全措置なしには脆弱になる可能性のある個体群を持つ。

gray wolf

最も広い分布域を持つ野生のイヌ科動物であるハイイロオオカミは、北アメリカからユーラシアにかけてのツンドラ、森林、草原などの多様な生息地に分布します。優位な繁殖ペアに率いられた家族単位の群れで生活する高度に社会的な動物です。キーストーン捕食者として獲物個体群を調整し、生態系の構造を根本的に形成することは、イエローストーンでの再導入により実証されています。かつて激しく迫害されましたが、多くの地域で個体群は回復しつつあります。
