VALUE AND USE
SPECIES: Carex saxatilis | Russet Sedge 



WOOD PRODUCTS VALUE : 
NO-ENTRY


IMPORTANCE TO LIVESTOCK AND WILDLIFE : 
Russet sedge communities provide moderate herbage production (840 to
1,160 pounds per acre [720-1,305 kg/ha]).  Cattle and elk use has been
noted.  The wet soils it occurs in decrease its grazing value [7,16].
In Iceland it rates as very good pasturage, even in winter [10].


PALATABILITY : 
The palatability of russet sedge is relatively low [7,8].  It is more
palatable than beaked sedge (Carex rostrata) and less palatable than
water sedge (Carex aquatilis) [16].  In Iceland it rates as very good
pasturage, even in winter [10].


NUTRITIONAL VALUE : 
NO-ENTRY


COVER VALUE : 
NO-ENTRY


VALUE FOR REHABILITATION OF DISTURBED SITES : 
Russet sedge may be useful for revegetation of degraded riparian sites
at high elevations.  Once established, it provides excellent soil
stability because of its long creeping rhizomes [7].


OTHER USES AND VALUES : 
NO-ENTRY


MANAGEMENT CONSIDERATIONS : 
The russet sedge community type appears to be a stable one with species
compositions only slightly impacted by past livestock grazing.  Because
of the organic, wet soils, use of heavy machinery should be avoided in
russet sedge communities [16].

BOTANICAL AND ECOLOGICAL CHARACTERISTICS
SPECIES: Carex saxatilis | Russet Sedge 



GENERAL BOTANICAL CHARACTERISTICS : 
Russet sedge, a native perennial grasslike plant, grows 8 to 30 inches
(20-80 cm) tall.  It is a turf-forming, perennial sedge with
well-developed, creeping rhizomes.  It has separate staminate and
pistillate spikes.  The achenes are trigonous. [7,9,21].


RAUNKIAER LIFE FORM : 
   Geophyte


REGENERATION PROCESSES : 
Russet sedge reproduces vegetatively by rhizomes and sexually by seed
[7].


SITE CHARACTERISTICS : 
Russet sedge grows in wet meadows and boggy areas, especially near
streams and lakes at high elevations [9,13,19,21].  It is often a
codominant in water sedge associations [16,17].  It is more common on
wetter than less wet sites [11].  Russet sedge grows on poorly developed
soils along shores and on organic substrates [7,16].  The water level
may be aboveground through spring and early summer [17].  Its
elevational range is 9,300 to 12,000 feet (2,835-3,660 m) in Utah and
Colorado and 4,800 to 5,600 feet (1,465-1,710 m) in Montana [2].

Russet sedge is often associated with water sedge and other sedges
(Carex spp.), bluejoint reedgrass (Calamagrostis canadensis), tufted
hairgrass (Deschamsia caespitosa), variableleaf pondweed (Potamogeton
gramineus), subalpine fir (Abies lasiocarpa), lodgepole pine (Pinus
contorta), Engelmann spruce (Picea engelmannii), and quaking aspen
(Populus tremuloides) [16,17].


SUCCESSIONAL STATUS : 
NO-ENTRY


SEASONAL DEVELOPMENT : 
Russet sedge has mature fruit in late July and August [13].
