Of particular concern to London is the presence and spread of the invasive plant species Phragmites . See Appendix A: Phragmites australis (European Common Reed) – Canada’s Worst Invasive Plant for a more in-depth look at the threat of Phragmites currently present in London’s Natural Heritage System. A stronger focus on this species is necessary. London’s neighbour, the City of St. Thomas, has recently approved a “Phrag Free City 2020” management plan, which outlines action items to reach the goal to eradicate Phragmites from all public and private lands by the year 2020. See Appendix B Case Study 1 – City of St. Thomas for more information.
