CONVERGENCE
A river meandering through the ood plain once ran through this place. The river shifted and left gravel beds behind. Mining interests extracted aggregate. High water tables reclaimed the pits turning them into pools. The ponds existed unmanaged and allowed invasive species to claim the disturbed territory. Informal recreation brought people and vehicles. Studies began. People documented the place while proposing conservation strategies. Residential development expanded. People pushed against the ponds. Recreational infrastructure was installed. The surrounding neighborhood has been drawn to the place. They are an ecological community in dialogue. People are in the pond.

A popular place. People like it here. They never stay long. Most people leave after two minutes.
Rarely used. But demonstrated the strongest pull of captivation.
An abrupt and reective destination.

Finding Places
contained human use
There are few places that they call their own Or maybe there are just few places where we cannot find them At least there are few places where they can be left alone Are there places for us to do the same?
habitat corridor
We fit in completely As long as we fancy That we do it delicately and with charm But let us remember The cause and the starting That deemed this place special with right The pond and the critters The episodic sunshine The birds and their pride for their young A living framework For all to witness As it changes with the markings of time So as the people come down here Let them do it with caution Else they push what is left away
