Vernal Pools

This project complemented and enhanced the restoration of the historical hydrology of the area by providing needed seasonal habitat for reptiles, amphibians and migrating waterfowl after the completion of the USEPA mandated thorium cleanup activities. The project was also identified in the $10 million NOAA grant that was awarded to the County in 2001.

The project created two vernal pools, each approximately 0.3 acres in size in DuPage County, Illinois on the Roy C. Blackwell Preserve. The goal of the project was to provide specific habitat to meet the needs of species that rely on seasonal or temporary wetlands as part of their life stage development; examples include amphibians (salamanders, frogs, toads). Vernal pools are a rare habitat in DuPage County; many vernal pools have been lost due to human activities, and the remaining pools are often altered due to changes in hydrology (water inputs and outputs) and land use.
