If the well is being dug specifically to maintain water levels in the wetland, it can be put in close enough to allow water to trickle into the wetland over land. Engineering this type of setup will create yet another type of wet area termed a bog. A bog is waterlogged, spongy ground that is not covered by water but remains wet all year round. It will establish its own specific plant community of species such as sedges. This area will be a natural attractant for frogs and aquatic insects which will in turn entice other wildlife to visit during feeding periods.
Larger wetlands have the capability of providing homes to many wildlife species.
Depending on the location, wood ducks or other waterfowl may be lured to your water. If a pond contains minnows, crayfish, or a good supply of frogs, wading birds such as the great blue heron may be observed while in search of a good meal. Increasing the diversity of a wetland can be accomplished by providing structure on the sides and bottom of the pond. Structure can consist of rocks, logs, brush piles or any materials upon which aquatic organisms can attach or hide. Placement of structure can be controlled more if it is done before the wetland is filled with water.
