Local occurrence (where, how common)
This sedge species is a common dominant in disturbed riparian areas, less commonly forming dense communities in healthy areas. It is can be especially dominant in grazed areas because it resists grazing and trampling damage (3).

Collection restrictions or guidelines
Collect the seed from August through October. Seed set may be variable, so verify how much collection is necessary before beginning to harvest (1,2). Seed may be collected by hand or by clipping off the seed heads. A power harvester can also be used for large-scale harvests of dense communities. Seed should be cleaned using a seed cleaner with a No.8 top screen and a No.20 bottom screen. The screens should be sized so the seed will fall through. Perigynia should be removed using a seed scarifier or sandpaper box, then separated from the seed using screens (2).
Germination rate is improved by removing the perigynia and pre-chilling the seeds in wet sphagnum moss at 2°C for 30 days. When germinating seed in a greenhouse, place seeds on the soil surface and lightly press to ensure good contact with the soil. The seed should not be covered and soil should be kept muddy. The greenhouse should be kept hot (32-38°C). Ideally, germination should begin in roughly a week (2).

Recommended planting density
If planted 30-45 cm apart, plugs will fill in the area within one growing season (2).
Care requirements after installed (water weekly, water once etc.)
During propagation and after installation the soil should be kept saturated, with the water rarely dropping below the root zone. No more than 2.5-5.1 cm of standing water should be present, however. The species can tolerate both periods of drought and complete inundation once established (2).
