Hall’s
Bulrush, Schoenoplectus
hallii
Hall’s bulrush is an
annual grass-like plant, which reaches a length of 35 cm long.
It is a widespread species, but rare throughout its range.
The bulrush is critically imperiled in Indiana.
It is a permanent plant that may be part of a seed bank for many
years before germination occurs. They
inhabit shores and bottoms of shallow temporary ponds, sinkhole ponds, and
coastal plain marshes. The
main characteristic of their habitat is that the water fluctuates
regularly to keep sands free of other competitive vegetation.
Although some of these habitats may desiccate, the seeds can
survive in the dry soil seed bank for many years.
Threats to this plant include off-road vehicle use, herbicide,
introduction of exotic plant species, excessive grazing, residential
development and filling of wetlands.
To help Hall’s Bulrush, the stable, yet changing habitat should
not be disturbed.
