A Framework for Guiding Habitat Rehabilitation in Great Lakes Areas of Concern (Environment Canada, 2004). The framework provides science-based information about how much wetland, riparian and forest habitat is enough to sustain biological diversity and vital natural processes. The Salmon River watershed is an area of 921 km 2 that drains into the Bay of Quinte near Shannonville, between Napanee and Belleville. The Bay of Quinte was identified as one of 43 Great Lakes Basin "Areas of Concern" in 1985. The International Joint Commission recognised that several of the Bay's beneficial uses were impaired as a result of industrial, agricultural, municipal and household practices that had contaminated the water. In addition to posing risks to human health, some of the diversity of plant and animal life had been lost. This study has found that stream bank naturalization presents the greatest opportunity to restore fish and wildlife habitat in the Salmon River watershed, especially in the southern portion. There are also areas surrounding wetlands in need of naturally vegetated buffers. Beyond identifying priority restoration sites, this report presents a broad spectrum of spatial information to assist appreciation and conservation of the watershed's natural wealth.

Green, October 2004 The Salmon River Habitat Strategy: 7 Identifying Priority Sites for Habitat Restoration in the Salmon River Watershed 1.0 Introduction The Canadian Wildlife Service of Environment Canada has produced How Much Habitat is Enough? A Framework for Guiding Habitat Rehabilitation in Great Lakes Areas of Concern (2004) in collaboration with the Ontario Ministry, qf thE), Environment and the Ontario Ministry of Natural Resources. Currently in its second edition, the framework provides science-based information to help guide decisions regarding: • How much habitat is needed to support a naturally functioning ecosystem; and • Priority locations for wetland, riparian and forest rehabilitation and protection across a watershed or landscape, These habitat guidelines provide benchmarks for evaluating the health of a watershed, using Geographic Information Systems to analyze and portray relevant digital map data. The present study was undertaken by the Ontario Ministry Natural Resources to reveal priority sites for habitat restoration in the Salmon River watershed.
