Lakewide Action and Management Plans

In 1987 the governments of Canada and the United States made a commitment, as part of the Great Lakes Water Quality Agreement to develop a Lakewide Management Plan for the Great Lakes which is coordinated by federal, state and provincial government agencies. The LAMP unites a network of stakeholders in actions to restore and protect the Lake Ontario ecosystem.

Other Plans and Reports

The key elements of the Lake Ontario LaMP's Binational Biodiversity Conservation Strategy are:

  • integration of action priorities into existing programs and "place-based" planning activities especially within key watersheds, an activity best done by local governments and organizations
  • regional coordination of lakewide scale biodiversity monitoring and restoration activities.
