Are hedgehogs national protected animals？Yes.
刺猬是国家保护动物吗？是的。
We are very pleased to report that not only are they the most adorable little animals in the world but they are also extremely important. The reason for this is because they are known as an indicator species. What this means is that we can study the habits of hedgehogs as an indicator of the health of the environment and nature as a whole.
它们不仅是世界上最可爱的小动物，而且它们很重要。因为它们被称为指标物种。这意味着我们可以通过研究刺猬的习惯，来判断整个环境和大自然是否健康。
To explore this in more detail we need to look into the dietary habits of the hedgehog. One of the main dietary sources for hedgehogs is soil invertebrates. These include worms among other creatures. As such, any environmental disturbances can be very detrimental to hedgehogs. If worms die off, so will hedgehogs. Assessing the hedgehog population is one of the most vital ways we can keep track of the quality of the environment in which they are feeding.
为了更详细地探讨这一点，我们需要研究刺猬的饮食习惯。刺猬的主要饮食来源之一是土壤无脊椎动物。其中包括蠕虫等生物。因此，任何环境干扰都可能对刺猬非常有害。如果蠕虫死亡，刺猬也会死亡。要想跟踪评估一个喂养着刺猬的环境的质量，最重要的方法之一就是看他们的数量。
