In today’s crowded world, we have to be creative about space for wildlife and find habitat opportunities in unexpected places.
A small, legacy gravel pit in Huron County is part of the solution. Wise Pit is a former extraction site that was once a farm field. At the end of its productive life, the pit sat fallow until it was taken up by a rehabilitation program funded by the aggregate industry to rehabilitate legacy sites.
TAKING STEPS TO REHABILITATE A LEGACY GRAVEL PIT
The Management of Abandoned Aggregate Properties program fills a gap for aggregate sites that did not require a rehabilitation plan. The program, coordinated by Danielle Solondz of The Ontario Aggregate Resources Corporation, evaluates these legacy sites to determine whether they can be rehabilitated into productive land use. These uses can include “wetlands and habitat for wildlife, farmland, parks, fruit orchards, vineyards, subdivisions, golf courses and recreational fishing areas.”
“Some legacy sites are rehabilitated as wetlands, but many become wetlands naturally,” says Solondz. “Rehabilitating Wise Pit has been an opportunity for us to learn more about the creation of wetlands. With this knowledge, we can implement these practices at more sites across the province.”
Wise Pit had evolved into a seasonal wetland—filling with water each spring and slowly drying out over subsequent weeks. The private landowner wanted to see the habitat improved for wildlife.
Michael Williams, DUC’s habitat restoration specialist in Ontario, determined that the site was suitable for wetland enhancement. He prepared a design for two wetland cells on the property, which includes contouring of the basins to encourage different types of wetland plants. The first step was to control the invasive reed, phragmites, which was removed to ensure the success of native vegetation. Mike is DUC’s head of habitat restoration consulting services in Ontario.
Wise Pit is on the path to become a wildlife paradise.
Making space for biodiversity on the working landscape
In southern Ontario, we must manage “natural infrastructure” systems—waterways, grasslands and wetlands—or face the continuous loss of birds, turtles and other wildlife. Rehabilitation of former aggregate sites can restore some of the space that wildlife has lost.
An investment in wetlands is an investment in Ontario’s future.
