FIRE EFFECTS
SPECIES: Antennaria microphylla | Rosy Pussytoes 



IMMEDIATE FIRE EFFECT ON PLANT : 
Rosy pussytoes is probably killed by moderate or severe fires.  However,
no marked rosy pussytoes plants were killed by low-severity spring or
fall prescribed fires in mountain big sagebrush (Artemisia tridentata
spp. vaseyana)/rough fescue (Festuca scabrella), mountain big
sagebrush/Kentucky bluegrass (Poa pratense), or Douglas-fir/mountain big
sagebrush vegetation types in the Helena National Forest, Montana [20].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
The response of rosy pussytoes to fire probably depends on site
characteristics and fire severity.  It is a major early seral species
following fires in subalpine fir/beargrass habitat types in central
Idaho [21].  Rosy pussytoes was first observed in postfire year 3
following the severe Sundance Forest Fire in northern Idaho [23].  In
Douglas-fir stands in the Deerlodge National Forest, Montana, rosy
pussytoes decreased 22.5 percent in the first 2 postfire years after
spring fires [7].  In sagebrush habitats in Idaho rosy pussytoes
decreased the first years following September prescribed fires, but then
increased and regained much of its original cover.  Production was
greater on lightly burned or moderately burned sites than on either
unburned or severely burned sites 15 years after the fires [3].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY
