In short, it is a very logical scale. Action should be taken on this scale. That would make it possible to work in several types of wetlands with different and complementary functions. Peat bogs, marshes and swamps are examples of that. Some wetlands are also said to be isolated or riparian. They are directly linked to watercourses. They do not have the same function at all, but they are also relevant.
We have to find a way to establish criteria to assess the importance of those various wetlands.
