FIRE EFFECTS
SPECIES: Antennaria racemosa | Raceme Pussytoes 



IMMEDIATE FIRE EFFECT ON PLANT : 
Raceme pussytoes is probably killed by most fires.


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Raceme pussytoes response to fire varies.  It decreased in cover in the
first years following stand-replacing wildfires in
Douglas-fir/pinegrass, Douglas-fir/ninebark, and Douglas-fir/globe
huckleberry habitat types in central Idaho and western Montana [2,21].
However, it increased after fires in subalpine fir/beargrass habitats
and was often found in the understory of open lodgepole pine (Pinus
contorta) stands, especially where one or more light surface fires had
recently occurred [19].  Raceme pussytoes was present in increasing
numbers in the first 10 years following the Pattee Canyon Fire in
western Montana [24].  Raceme pussytoes was also present within 7 to 9
years following a broadcast burn in a western larch (Larix
occidentalis)-Douglas-fir forest in Montana, although it was not a
component of the prefire community [22].  Reese [18] stated that raceme
pussytoes is sometimes present on recently burned sites in the Teton
Wilderness, Wyoming.

Anderson [1] reported that raceme pussytoes was present "via vegetative
regrowth" in postfire year 1 following moderately severe fires in
lodgepole pine stands in Yellowstone National Park.  No other
information was found on the ability of raceme pussytoes to sprout after
fire.


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
NO-ENTRY
