I'll just give you a specific example. I'll go back to a program that we manage in partnership with naturalist organizations across the country. It's called Important Bird Areas and it focuses on conserving a suite or individual bird species. One of the problems with that, when you look at the prairie landscape, the grassland landscape, for example, is that it's really hard to take a species and/or a site-specific approach to conservation. Indeed we need more holistic approaches, so the ecosystem approach, in many respects, across this landscape, this ecosystem, and others across the country is very important.
