Well, the 1917 act was built around addressing the specific problem of rapid species decline, the millinery trade acquiring feathers from migratory birds. It really focuses on addressing that particular circumstance.
We've learned in the 100 or so years since that time how biologically diverse and valuable these habitats are for a multitude of species, and that's just on the plant and animal side. Then there's the whole human benefit, and now we're just getting into better understanding of what the economic benefits are.
So I'm not sure that managing it in the context of the migratory bird act is the best place to do it.
