National wildlife corridor

A definition of a wildlife corridor from Wikipedia is below. 

I thought that somebody somewhere had developed a *national* plan for a wildlife corridor--meaning that all the bioregions in the U.S. would be connected by a continuous corridor through which wildlife could move and populate freely without hindrance by human activity (including hunting or harvesting).   It could also be thought of as a wildlife preserve.  

But a cursory check with Google doesn't seem to show any such development.    Apart from romantic notions of preserving a nature untouched by human activity,  it would seem to be a another way of helping to preserve biodiversity.  

The article below points out some of the limitations of the notion, but it still beats zoos and possibly botanical gardens & herbariums--or putting ova and seeds in deep freeze.  

I guess it would be necessary to build bridges or tunnels for the critters to get across freeways and the like.
