Carex barbarae is a perennial (photos). It grows dark green 18-24 inches high. You can grow clumps and divide them into as many as fifty nodes in a year. They transplant very well into poor silty soils. They then propagate from rhizomes. It grows into Southern Oregon, but I suspect it is sensitive to salt (see the map at the link). I don't know about its fire tolerance, but since the Indians used to burn the places from which it originates, and because the plant spreads from rhizomes I suspect it would do fine after a fire as long as the ground was dry enough when it burned.
This page has information on native grasses you might also find useful. The seed is expensive, but because they are perennials that seed annually, you get a lot of bang for your buck if you know how to mow preferentially.
Thanks for the data.
