Why are vernal pools important?
Vernal pools provide a breeding habitat for thousands of species, some of which depend on them for survival. An estimated 85% of amphibians return to breed to the same vernal pool in which they were born. If the vernal pool is destroyed, the amphibians will try to breed elsewhere, such as on your house or in a parking lot, with less chance of survival.
Furthermore, they reduce seasonal flooding, replenish the groundwater supply, purify surface water runoff, and maintain biodiversity. Vernal pools are nearly impossible to replace, and they should be protected.
