Can plants indicate the health of ponds?

Freshwaters and their biodiversity are a fascinating subject in which to study as they are very responsive to human influences, are found all over the globe and we seem to have a draw towards them (from feeding the ducks to boating). But freshwaters globally are in a bad way; there are now fewer of them, their quality is declining and their biodiversity is suffering as a result. Knowing about a problem is one matter, but understanding and doing something about this is more difficult. In an attempt to slow the decline of freshwater habitats, there are several approaches to conserve, restore or enhance waterbodies.
