Tree populations in the wild usually satisfy those criteria.

在野外生长的树木一般可以满足这些要求。

Within the savanna, all of the zebras make up the zebra population, all of the acacia trees make up the acacia tree population, and all of the lions make up the lion population.

在这个热带草原里，所有的斑马构成了斑马这个种群，所有的金合欢树构成了金合欢种群，所有的狮子构成了狮子种群。

On top of that, the Everglades are home to the largest mangrove tree population in the western hemisphere, which not only form habitats locally, but also help shield those inland plants, animals, and people from storms.

最重要的是，大沼泽地是西半球最大的红树林种群的家园，它们不仅在当地形成了栖息地，还有助于保护内陆的动植物和人类免受风暴的影响。
