The Ontario Stone, Sand & Gravel Association (OSSGA) released a study that shows reclaimed sties are being successfully integrated into their communities and surrounding landscapes once rehabilitation is complete.
“Aggregate extraction has become controversial in recent years, especially since there’s been very little information available about rehabilitated aggregate sites in the province,” says OSSGA CEO Moreen Miller. “As a result, we’ve had no accurate, objective data to either praise or criticize how former aggregate sites have been rehabilitated.”
The association hired a team of planners and ecologists to review 337 sites that had been licensed aggregate operations. Field visits produced data on each property, including amount of tree coverage and native vegetation, as well as current site use, surrounding land uses, and municipal zoning.
Among the findings was that the land uses of the sites are natural (32 percent), residential (15 percent) recreational (13 percent), water (11 percent), open space (11 percent), with other occurrences of industrial, commercial institutional, and other land uses. There is approximately 17 percent tree coverage on the sites across the entire study area, with an estimated 66 percent of plant life being vegetation that is native to Ontario.
