I. wetland dynamics are not totally understood. Reconstructed wetlands do not always provide the essential elements necessary to attract the species of the original habitat.
I. wetlands developed for the drinking water supply do not have to be replaced. This contributes to overall net loss of wetland .
III. There is no routine tracking of compliance to document success.
IV. The definition of wetland was broadened by Congress, adding marginal wetlands in addition to swamps and marshes.
