What is a Vernal Pool?

So what exactly is a vernal pool?

The term ‘vernal’ actually means relating to spring. Vernal pools refer to a unique wetland habitat that fills each spring with rain and snowmelt. These pools are typically shallow and dry up in the summer, but amphibians such as frogs, salamanders, and toads rely on these pools for breeding during spring.

Vernal pools are often damaged or destroyed because of human activity. These pools are filled with soil to flatten the landscape, and their water levels and water quality are impacted by different land uses close by.

You can help protect vernal pools by noting where they are found so you don’t disrupt them when the dry season comes.
