Since vernal pools have no inlet or outlet, they can't support fish or other known predators. This is an ideal safe haven for salamanders and some frogs to lay their eggs, while also serving as a primary place to live out the vulnerable aquatic stages of their life cycle. Amphibians require water to keep their skin moist. Unlike reptiles, they lack scales to help them tolerate dry conditions. This affinity for water makes it particularly important for us to avoid developing wetland areas.
Pollution is particularly dangerous to amphibians like frogs and toads.
These toxic substances can cause deformities and even death to these animals.
