City of Windsor Update to the CNHS Inventory June 2008 The Great Lakes Sustainability Fund is a component of the Federal Government’s Great Lakes program. The Sustainability Fund provides resources to demonstrate and implement technologies and techniques to assist in the remediation of Areas of Concern and other priority areas in the Great Lakes. This report was partially sponsored by the Great Lakes Sustainability Fund and addresses environmental issues in the Detroit River Area of Concern in Windsor, Ontario. This report does not necessarily reflect the views of the Sustainability Fund or Environment Canada.

The information within this document will be utilized as background information in the review and update of the Official Plan. In addition to other Official Plan background studies, the findings of the biological site inventories within this document will assist City Administration and Council with determining appropriate Official Plan land use designations and developing specific policy, as deemed appropriate in the updated Official Plan. Project Intent and Project Approach The intent of this study is to inventory and assess the most environmentally significant areas in the City that are not currently protected. This information can be useful to minimize urban development impacts and loss of significant natural features. The approach of this study is consistent with the City of Windsor’s Vision Statement and existing Official Plan, as well as the 2005 Provincial Policy Statement and the goals and objectives of the Essex Region Conservation Authority. 2005 Provincial Policy Statement The Provincial Policy Statement (PPS) is issued under Section 3 of the Planning Act . It provides direction on matters of provincial interest related to land use planning and development, and promotes the provincial “policy led” planning system. The updating of the CNHS inventory is necessary for the City of Windsor to be consistent with the requirements of the new 2005 PPS and to address Section 2.1 which is the Natural Heritage Section of the Policy Statement. The PPS requires that planning authorities protect significant natural heritage features and areas by restricting development and site alteration which would have a negative impact on their natural features and ecological functions. Part I of the PPS states, “provincial plans and municipal official plans provide a framework for comprehensive, integrated and long-term planning and supports and integrates the principles of strong communities, a clean and healthy environment and economic growth, for the long term.” City of Windsor Official Plan The Official Plan for the City of Windsor guides the physical development of the municipality for a twenty-year planning horizon. Based on the requirements in the Planning Act , Official Plans are to be reviewed at intervals of five years or less. The current Windsor Official Plan provides a Vision Statement which states, “Windsor, Canada’s southernmost city and 3 international gateway, is a diverse community of safe, caring neighbourhoods, with a vibrant economy and a healthy sustainable environment.” In order to achieve a sustainable, healthy environment, the most significant natural heritage features in the City of Windsor need to be protected and linked together to enhance the habitats and biological diversity of the greenway system. The City of Windsor’s Official Plan provides a commitment to the Vision Statement which is reflected in an action strategy centred around four interrelated themes. One of these themes is a sustainable, healthy environment. This theme is interpreted to provide the following. “Windsor values harmony between human activities and natural systems. To achieve a sustainable, healthy environment, the Official Plan will enhance Windsor’s natural environment by conserving the most environmentally significant areas and by encouraging appropriate urban development.” The preamble to the Environment Section of the City of Windsor’s Official Plan states: “A healthy and sustainable environment represents a balance between human activities and natural features and functions. In order to attain this balance, Council will enhance the quality of Windsor’s natural environment and manage development in a manner that recognizes the environment as the basis of a safe, caring and diverse community and a vibrant economy.” City of Windsor Greenway System The Greenway System is based on the belief that the quality of life within Windsor will be enhanced by the establishment of a linked and continuous network of “green” land uses. This planned network of natural environment and recreational elements will provide a means to establish Windsor as a healthy and liveable city (Policy 5.3.2 City of Windsor Official Plan). The core natural environment areas within the City provide wildlife habitat for a wide range of animals and plants. However, isolated patches of wildlife habitat are not enough to allow for sustainable, healthy populations. While some species move over agricultural lands, others require vegetated corridors between the core areas. These are essential to allow for migration of wildlife, to provide escape routes, and to foster biodiversity of natural communities and genetic pools. A connected and diverse natural system also provides a scenic landscape with opportunities for extensive trail systems. The outcome of this study will provide baseline information useful for developing and strengthening policies focused on the natural heritage system while integrating recreational elements. In fragmented landscapes such as the Essex Region, the identification of natural heritage systems, and the associated recommendations designed for their protection and restoration, can accomplish the following: 4 1. Maintain or enhance the overall diversity of species; 2. Conserve rare plant communities (e.g. alvars, prairies) and faunal species; 3. Maintain or enhance the long-term health of populations of native species; 4. Represent remaining types of ecosystems and processes; 5. Maintain and enhance natural corridors for wildlife travel and genetic variability; 6. Help protect the quality and quantity of water resources; 7. Establish priorities for restoration, stewardship and acquisition; and, 8. Assist decision makers in making sound, informed decisions on how and where development should occur without compromising the ecological integrity of natural systems. (Central Cataraqui Region Natural Heritage Study, 2006) This study was not intended to be a complete biological inventory of all natural heritage features within the City limits. Those sites which are under public ownership and currently protected were outside the scope of this study and may benefit from the preparation of comprehensive management plans. Regional Context Prior to European Settlement, the Essex Region was dominated by lush natural areas including Carolinian woodlands, wetlands and prairies. Most of the natural areas in the region were historically removed to allow for agriculture and urban development. As well, many of the natural areas which are the subject of this study, have resulted from regeneration from discontinued agricultural uses to prairie and forest communities. Today, the natural heritage system within the region is generally fragmented consisting of “islands of green” or isolated, remnant natural features scattered across the City and County. As demonstrated in this report, some plant and animal species in the region have been classified as “at risk” as there is insufficient and degraded habitat regionally to continue to sustain healthy populations.
