look after the park and patrol all year long. Wardens will be working closely with the local police to protect the visitors and the resources. The policy also focuses on restoring native ecosystems and wildlife landscape. Since 2014, Parks Canada has worked with the Toronto Zoo to rear and release 113 baby Blanding's turtles in the park; a threatened species, prior to this initiative, it was believed that only seven turtles remained in the park. Beginning in 2015, Parks Canada began to partner with park farmers and the Toronto and Region Conservation Authority to complete conservation and agricultural enhancements projects in Rouge National Urban Park. Urban pollution Rouge Park consists of acres of protected land right in the middle of a metropolitan area. It is home to various unique wildlife species that are otherwise at risk. The location of the park makes it vulnerable to many different sources of pollution. For example, one of Toronto's major highways cuts through the park. To provide a safe and recreational environment for visitors and maintain biodiversity, it is important to identify these sources and better manage the risks. Different types of pollution sources found in the park are listed below and the risks associated with them. Sources of urban pollution found in Rouge Park include: Many decades of urban development have led to increased erosion and channel instability. Erosion can cause sediment loading in streams and impact aquatic life. Eroded sediments can carry nutrients and other substances that can naturally build up in the soil, typical land development practices of an urban area have led to large concession blocks of soils being exposed at a given time. Much of the wetland in the park was drained and cleared to make room for agriculture. Farms are significant contributors to contaminants such as nutrients, bacteria and pesticides entering a river. In the park, the median concentrations of phosphorus range from 0.02 mg/L in the Little Rouge River to 0.05 mg/L in the Main Rouge, south of Highway 7 (provincial guideline is 0.03 mg/L). 24 golf courses, which can be a significant source of pesticides and nutrients, are located in the watershed. Golf course turfs also require a significant amount of irrigation which can threaten stream health. However, the surrounding golf courses have undertaken proactive measures to fit environmental standards. In the Rouge watershed there are six abandoned landfills. These pose the risk of leachates leaking
