From an ecological perspective, an eco-regional approach would make a lot of sense. They need to be knitted together at various scales. A municipal plan needs to be nested within a regional plan, and it goes up from there. You can have various levels of connectivity too. At the municipal level, you might talk about these riparian areas and about making sure there are protected corridors at that scale. At a regional scale, you need to think more broadly and think about a landscape kind of management approach. It really depends on the scale you're talking about.
