FIRE EFFECTS
SPECIES: Carex vaginata | Sheathed Sedge 



IMMEDIATE FIRE EFFECT ON PLANT : 
Sheathed sedge culms are probably top-killed by fire during the growing
season.


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Vegetation regrowth after fire is very fast in low arctic tundra sedge
(Carex spp.)-dominated communities [23].  Sedges increase in importance
following fire in these habitats [22].

Sheathed sedge in northern Ontario was sparse at the beginning of
succession after fire.  Its numbers continued to rise for 10 years.  It
then disappeared over about a 2-year period as black spruce and jack
pine (Pinus banksiana) began to regenerate [17].

Sheathed sedge occurs in the central Saskatchewan boreal forest, which
has had a history of frequent fire.  Sheathed sedge in previously burned
sites in this region occurred at a frequency of 31 percent in balsam
poplar stands.  Balsam poplar is considered a pioneer species.  Sheathed
sedge occurred at a frequency of 1 to 9 percent in later successional
stands, dominated by jack pine and black spruce, and did not occur at
all in climax vegetation [5].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
NO-ENTRY
