This country is so temperate, so fertile, so beautiful, that it may be called the earthly paradise of North America. Antoine de Cadillac 1702

We—human beings—are part of 'biodiversity.' We are dependent on the whole food chain down below us Darrell Merrell, heirloom vegetable farmer
The Great Lakes contain 6 Quadrillion gallons of water
18% of world’s and 95% of North America’s fresh surface water
Daily, 56 billion gallons of water are used by municipalities, agriculture, and industry
42 million people depend on the Great Lakes for their drinking water
17,000 kilometers of coastline
600 sand beaches in the U.S.
World’s largest collection of freshwater sand dunes
$1 billion/year recreational fishing industry
70 million people visit parks annually
$100 billion in world trade
Persistent harmful chemicals have been an enduring legacy for at least a hundred years, posing a threat to human and wildlife health
Invasive nuisance species are disrupting the food web and causing billions of dollars in damage to infrastructures such as water intakes. It appears the fishery is being affected
Destruction of habitats such as wetlands and river corridors, is resulting in diminished ecosystem services

Ecosystem services are the conditions and processes through which natural ecosystems, and the species that are part of them, help sustain and fulfill human life.
State-of-the-Art Approaches for Assessment of Great Lakes Nearshore and Large River Fish Habitat • Rivers—lack of real time monitoring; channel habitat data; large river floodplains • Nearshore—no comprehensive survey of bathymetry, substrate and vegetation; no uniform classification system across the basin
Habitat Modification • Rehabilitation emphasizes the reparation of ecosystem processes, productivity and services, not pre-existing integrity • Reclamation, usually applied to mining, is the stabilization of the terrain, assurance of public safety, aesthetic improvement, and usually a return of the land to what, within the regional context, is considered to be a useful purpose • Mitigation is an action that is intended to compensate environmental damage • Creation is conducted as mitigation on terrain that is entirely devoid of vegetation • Ecological engineeringinvolves manipulation of natural materials, living organisms and the physical-chemical environment to achieve specific human goals and solve technical problems
What is ecological restoration? • Ecological restoration is the process of assisting with the recovery of an ecosystem that has been degraded, damaged or destroyed
Habitat restoration timeline • Sources controlled • Sites restored • On a trajectory to full recovery Full recovery Trajectory On the road to recovery Restoration activities Long term monitoring
What interventions are employed in ecological restoration? • Interventions employed in ecological restoration vary widely among projects and programs • Removal or modification of a specific disturbance • Deliberate reintroduction of native species • Facilitate the resumption of those processes which will return the ecosystem to its intended trajectory
Indigenous ecological management • Ecological restoration may include the recovery of indigenous ecological management practices, including support for the cultural survival of indigenous people and their languages as living libraries of ecological knowledge • What makes ecological restoration especially inspiring is that cultural practices and ecological processes can be mutually reinforcing
What is meant by “recovery” in ecological restoration? • An ecosystem has recovered - and is restored - when it contains sufficient biotic and abiotic resources to continue its development without further assistance or subsidy Before After Ft. Erie, Niagara Peninsula Conservation Authority

Restoring to the future requires: • Understanding ecosystems • Development and use of appropriate tools • Linking ecological restoration and economic development • Sharing information • Partnerships The activist is not the man who says the river is dirty.
