FIRE ECOLOGY
SPECIES: Scirpus americanus | Olney Threesquare 



FIRE ECOLOGY OR ADAPTATIONS : 
Olney threesquare's rhizomes are sufficiently buried in soil, sometimes
up to 6 inches (15 cm), and are thus well protected from the heat of
fire.  Additionally, the plants often grow in shallow water which
further insulates the underground regenerative structures.

Olney threesquare seedling establishment after fire has not been
reported.  However, field studies show that Olney threesquare seeds
stored in the soil are not injured by marsh fires.  Palmisano [19] found
that seeds subjected to marsh fires, whether placed on a moist, but
unsaturated soil surface or buried 1 inch (2.5 cm) below the soil
surface had slightly higher germination rates than seeds not subjected
to fire.


POSTFIRE REGENERATION STRATEGY : 
   Rhizomatous herb, rhizome in soil
