Meet: Vernal Pools

Spring is in full effect this week. In the video below, vernal pools are referred to as "coral reefs of the Northern Forests". These unique habitats, characterized by their seasonal nature, play a crucial role in the life cycles of various species, particularly amphibians. As the temperatures rise and the snow melts, these pools come to life with a symphony of croaks and chirps, marking the beginning of the breeding season for many amphibian species.

Vernal pools are shallow depressions that fill with water during the wetter months, typically in spring, and then dry out as the weather becomes warmer. This cyclic inundation creates an environment that is perfect for certain amphibians, providing breeding grounds that are free from fish predators, which would otherwise consume amphibian eggs and larvae.

The Upper Midwest, encompassing states like Wisconsin, Minnesota, Iowa, and Illinois, boasts a rich tapestry of vernal pools. These pools can range in size from small depressions in the forest floor to larger, more expansive wetlands, each hosting a diverse array of flora and fauna. You can check out an amazing video from Michigan Nature Association below.

While vernal pools provide essential habitat for amphibians, they are also highly vulnerable to human activities and environmental changes. Urbanization, agricultural expansion, and climate change pose significant threats to these fragile ecosystems. Pollution runoff, habitat destruction, and altered hydrological patterns can all disrupt the delicate balance of vernal pools, jeopardizing the survival of fragile species.

Conservation efforts aimed at protecting vernal pools and their inhabitants are crucial for maintaining biodiversity in the Upper Midwest. Strategies such as habitat preservation, land-use planning, and community engagement can help safeguard these critical ecosystems for future generations. To learn more, visit:

Vernal pools represent an ecological treasure trove in the Upper Midwest, providing vital habitat for a diverse range of amphibian species. From the haunting calls of wood frogs to the stealthy movements of spotted salamanders, these ephemeral wetlands are alive with activity during the spring breeding season. By recognizing the importance of vernal pools and implementing effective conservation measures, we can ensure that these unique habitats continue to thrive for years to come, sustaining both amphibian populations and the broader ecosystem.
