Michigan forests are home to enchanting woodland ponds that are teeming with fairy shrimp, fingernail clams, and blue-spotted salamanders. These whimsical ponds may seem like something out of a fantasy novel, but they play a crucial role in the ecosystem.
Vernal pools, derived from the Latin word for spring, are seasonal wetlands that emerge in wooded areas during this time of year due to the melting snow and spring showers. These unique ecosystems, often referred to as the “coral reefs” of Eastern forests, have a short lifespan, drying up by the summer. However, during their brief existence, they provide vital habitat for a diverse and captivating array of wildlife.
In recent years, there has been a growing recognition of the importance of vernal pools in woodland ecosystems. Previously, these pools were not given much attention and were underprotected. However, experts now understand that vernal pools play a crucial role in recharging underground aquifers, aiding in flood control and erosion prevention. Moreover, these pools facilitate the rapid recycling of nutrients into the soil beneath them. It is fascinating to note that over 550 species have been identified as utilizing or relying on vernal pools, ranging from small crustaceans and rare turtles to majestic black bears and red-shouldered hawks.
In Michigan, the Vernal Pools Partnership is actively involved in the mapping and monitoring of vernal pools. This coalition, consisting of government agencies and nonprofits, is dedicated to vernal pool education, outreach, and research. To assist in their efforts, they have enlisted the help of a group of volunteers called the Vernal Pool Patrol. During late March and April, these dedicated individuals can be found in the field, wearing waders and muck boots, as they collect water samples and document their findings. Their main objective is to identify the “indicator species” that indicate a thriving habitat.
In the world of indicator species, there are some fascinating creatures that play a crucial role in the ecosystem. One such species is the fairy shrimp, delicate crustaceans that elegantly swim upside down using their 11 pairs of rippling legs. These inch-long creatures are known for their ethereal beauty. Additionally, we have the lively wood frogs and two types of salamanders that migrate in large numbers to these pools during warm, rainy nights. Together, these indicator species provide valuable insights into the health and balance of their habitats.
In the woods, there is a unique springtime frog that has a distinct sound resembling that of a tiny chicken. This fascinating creature captures the attention of anyone fortunate enough to come across it.
The Michigan Vernal Pools Partnership not only provides annual volunteer training for the Vernal Pool Patrol but also offers guided and family-friendly explorations of vernal pools throughout the spring. These explorations aim to educate people about the significance of these woodland wonders. It is important to note that due to the sensitivity of these ecosystems, experts strongly advise against exploring them independently.
