E Harmful Effects of the Cygnus olor Population on the Biodiversity of the Presqu’ile Provincial Park Wetland Ecosystem

Abstract

Presqu’ile Provincial Park in Southeastern Ontario is a major attraction for campers and outdoor enthusiasts year-round. At the forefront of the Park’s popularity is its rich biodiversity, supported by a variety of unique ecosystems. A particular ecosystem of interest, the park’s wetland, is one of the largest along Lake Ontario. However, working with a Biodiversity Specialist from Ontario Parks, we have identified a major issue that has threatened to upset the delicate balance of this ecosystem. Recently, large colonies of Cygnus olor, more commonly known as the mute swan, have begun to nest in the wetland area. This species is extremely territorial and the swans exhibit aggressive behavior towards other species inhabiting the same niche. The main consequence from this territorial behavior is that previously common waterfowl species no longer nest in the wetland. Unfortunately, once C. olor nest in a particular area, dislodging the swan population is very challenging. Using available data from peer-reviewed journals, popular media, Ontario Parks and the Ministry of Natural Resources, our group hopes to analyze the current situation, to identify possible root causes, and to develop viable methods of C. olor population control, in order to restore the wetland’s natural biodiversity. Our seminar will provide a detailed discussion of results from our analysis as well as evaluate potential solutions towards controlling the increasing populations of C. olor. We endeavour to provide future measures that may be implemented to preserve Presqu’ile Provincial Park’s biodiversity and that have potential applications on a global scale.
