This location is a small mitigation wetland created about three years ago
and flooded and planted two or three years ago at most. The city of Delaware
Ohio manages the new park (a hilltop recreational trail invites bikes and
walkers). It's close enough to the Olentangy River to attract overflight
migrants using terrain features as navigation cues. It is a good example of
a responsible attempt at effective mitigation by introduction of very high
biodiversity in an attempt to introduce a self-sustaining ecosystem (if
that's possible) in a new small excavation (this was an average farm field a
few years ago--still is in the Google Earth image dated 2006). Many
"mitigation" attempts result in little more than retention ponds with a
light mix of wetland species tossed in. A few firms take a different
approach, attempting to leave an enduring wetland behind. This looks like
one of these attempts to me. It is especially vulnerable to trampling at
this time because it is very small and newly established. The plant
assemblage is impressive, the macroinvertebrate fauna may be far less
impressive and may never mitigate for loss of 'real' wetland, but the birds
like the place, so do birders. Both are getting their fill, for now.
Tread lightly.
This location is designed for heavy multiple use--and will be used very much
as it is discovered by more and more user groups (last time I was there I
watched a bicyclist practicing acrobatics using the paved trail). If birders
stay on the trails and dike--birds will undoubtedly remain observable. A
little patience goes a long way!

Um,
Isn't the marsh in question a 'permit access only' site?
If so, perhaps it is for some of the reasons already stated
If not, I'm confusing it with another location it that general vicinity.
Of course this poses another, rather than answering any, question.
