Grey Club Rush

More info for the term: marsh

The effects of fire on wetland plants after drawdowns in Utah's Great
Salt Lake Marsh were studied [27]. On burned sites new shoots had a
lower biomass per inch of length than shoots on unburned sites.

Prescribed fires were lit in early September following April drawdowns
in the Great Salt Lake Marsh [27]. No distininction was made between S.
validus and S. acutus in this study. Both were referred to as S.
lacustris. Burned and unburned sites were reflooded 1 week following
fire. Stands of bulrush on burned sites were similar to those on
unburned sites during the first year. Bulrush began sprouting
immediately following fire, growing to a height of 1.3 feet (0.4 m)
before the first winter. Production did not differ between sites.

Waterfowl and muskrats can reduce soft-stem bulrush through overgrazing,
especially following fire [27].

More info for the term: cover

Soft-stem bulrush provides good cover for waterfowl, especially in
conjunction with common cattail (Typha latifolia) [13].

More info for the terms: achene, fruit, marsh

Soft-stem bulrush is a tall, leafless marsh plant 1.5 to 9 feet (0.5-3
m) high and 0.12 to 0.8 inches (0.3-2 cm) thick with scaly, stout,
horizontal rhizomes [11]. The stems are obscurely three-sided and
spongy [17]. Spikes occur near the stem tips in branched clusters [8].
The fruit is an achene [11].

Soft-stem bulrush occurs throughout North America from central Alaska
south to Mexico, east to the Maritime Provinces of Canada, and south
through Florida. It does not occur through central and southern
California [8]. It is native on the Hawaiian islands of Niihau, Oahu,
Molokai, and Hawaii [34].

More info for the term: fresh

Soft-stem bulrush grows in marshes, along lake and stream shores, and in
wet meadows. It grows in fresh or brackish water [5,16,23]. Soils are
usually poorly-drained [5], or continually saturated [12]. Soft-stem
bulrush grows in silty or peaty soils [18]. Under greenhouse conditions
soft-stem bulrush produced more aboveground biomass in silty clay soils
than in clay or sand alone [1]. Belowground biomass was equal in silty
clays and clays, and lower in sandy soils. Soft-stem bulrush seems to
grow better in saline conditions than in fresh water, and it tolerates a
wide range of salinity [32].

Fire topkills soft-stem bulrush stands [13] and reduces shoot mass of
Scirpus species [27].

The seeds of soft-stem bulrush are eaten by waterfowl and considered a
good to excellent food source in South Dakota [3,9].

Soft-stem bulrush is a dominant in the following classification type:

Livestock grazing in wetlands can reduce soft-stem bulrush [13].

Soft-stem bulrush will establish from the seedbank following periodic
draining and reflooding of marshes [6,22]. However, prolonged draining
and reflooding can reduce soft-stem bulrush stands [18]. In a Minnesota
marsh, early to mid-June drawdowns favored soft-stem bulrush stands in
the first 2 years. After the third-year drawdonw, bulrush began to
decrease in water depths greater than 15 inches (38 cm). Eventually it
was eradicated from all areas reflooded annually [18].

Roots of soft-stem bulrush can be ground into flour or eaten whole.
Syrup can be extracted from them [8].

Because of the wide distribution of soft-stem bulrush, its growing
seasons varies with latitude. In the northeast soft-stem bulrush
flowers from July through August [23]. Flowering lasts from 5 to 6
months in wetland prairies of Nebraska [28]. Fernald [11] reported
fruits generally ripening from June through September.

Soft-stem bulrush sprouts from rhizomes following fire [27].

Fire increases protein content of Scirpus acutus, a closely related
species [33]. Wetland vertebrates may select certain marsh plant
species due to protein increases following fire [27].

More info for the term: seed

Soft-stem bulrush reproduces by both rhizomes and seeds [11,17]. It
reproduces well from seed stored in the seedbank [18]. Soil-stored
seed can remain viable for as long as 20 years [31]. In the lab, seed
viability in dry storage is more than 2 years [14].

Facultative Seral Species

Soft-stem bulrush is a perennial [17] and is a dominant emergent in the
northern plains and prairie states [19]. It is replaced by cattail
(Typha spp.) in continuously flooded marshes following drawdown [18].
Soft-stem bulrush is found in the third sere of succession in Wisconsin
marshes, preceded by submerged and floating plant stages and followed by
sedge meadows, shrubs, and trees [12].

The currently accepted scientific name for soft-stem bulrush is
Schoenoplectus tabernaemontani (K.C. Gmel.) Palla (Cyperaceae) [35,36].

More info for the term: restoration

Soft-stem bulrush is used in wetland restoration and is best planted
vegetatively because it can triple its biomass in one growing season
[20]. It is also used to reduce pollutant loads carried by storm water
runoff in urban wetlands [25].
