                                            Spartina alterniflora, Zhangjiang Estuary.

                                  S. alterniflora encroaching on mangroves.

The following show mariculturists working on the mudflats at low tide

            Note mangrove and Spartina seedlings, which interfere with their activities.

Note the razor clam harvesters among the invading S. alterniflora.  A tragedy of the commons. To remove Spartina costs time needed to be spent cultivating clams.
