i live near a salt meadow, (now a city park, a wonderful, unimproved salt water marsh).

some houses in the neighborhood, have codicils in the deed, saying how many acres of salt hay they harvest a year.

salt hay, (and WW, the Veld grass that has no seed and no nutrictional value) was used as a garden mulch. the seed needs brakish water to germinate, so it wouldn't in a normal garden, and the plants composted readily, adding nutrients to the soil. salt hay was used for asparages beds, and to keep melon and pumpkins off the ground, and for coving up parsnips..

I pass through the salt marsh park each day (the train tracks were layed down before it became a park, and continue) every day is treat. yesterday, the resident swans were out, patroling their domain. there is also a hugh osprey nest, and scores of other birds. the cove is a protected nesting site for Horseshoe crabs.
