Pwc. Uhlig et Jk. Jordan, A SPATIAL HIERARCHICAL FRAMEWORK FOR THE COMANAGEMENT OF ECOSYSTEMS IN CANADA AND THE UNITED-STATES FOR THE UPPER GREAT-LAKES REGION, Environmental monitoring and assessment, 39(1-3), 1996, pp. 59-73
Over the past three decades, considerable effort has been invested in
the development of complex and comprehensive ecosystem classifications
and inventories in many parts of North America. Paralleling this has
been an evolution in those hierarchical frameworks guiding the develop
ment and application of classifications. However, resource management
agencies continue to grapple with the dilemma of applying multiple cla
ssification and inventory templates over large jurisdictions, especial
ly as they attempt to address ecosystem management objectives. Given t
hat Canada and the United States share ecosystems and that commitments
have been made by all levels of government to make progress towards e
cosystem-based approaches to management, there is a need to provide th
e proper tools. Comprehensive goals will not be achieved without colla
boration and cooperation. This paper outlines the range of ecosystem c
lassification approaches that exist in the Upper Great Lakes region. C
anadian and American national hierarchical frameworks are briefly exam
ined. Specific information needs and tasks are outlined which must be
followed, independent of national boundaries, for the successful integ
ration of planning and monitoring programs for large regional ecosyste
ms. A general model is proposed for the development and application of
an integrated, multi-scale and bi-national ecosystem classification,
inventory and information system. This approach would facilitate data
sharing and communication across jurisdictional boundaries.
