This article from Seattle-based publication WorldChanging describes regional planning efforts to protect sensitive fisheries. This regional planning is not based on political boundaries, but rather on biological boundaries.
"Beyond the cities or rural dwellings we live in, we all live in a bioregion. Bioregional planning requires deep collaboration among people living sometimes far apart among diverse ecosystems. Bioregions can be defined based on a watershed or species habitat or other features in the landscape, but generally they are made up of many diverse ecological niches."
"The historic habitat range of salmonids and steelhead is an example of a bioregion and Ecotrust, an environmental organization from Portland, Oregon, is helping forge the way for bioregional planning, economics and cultural integrity by taking a whole systems approach to habitat conservation and species preservation."
