FIRE EFFECTS
SPECIES: Vicia americana | American Vetch 



IMMEDIATE FIRE EFFECT ON PLANT : 
Fire probably top-kills American vetch [27,39].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
American vetch typically increases after low- to moderate-severity fires
[5,6,38].  In a study of plant succession in the Gambel oak (Quercus
gambelli) brush zone in Utah, American vetch showed a higher average
number of plants on burned areas than on unburned areas, even after 9
years [22].  In northeastern North Dakota American vetch canopy cover
was greater on some sites burned 1-3 years before the plant survey than
on unburned sites [24].  In a Douglas-fir habitat type in Idaho,
American vetch cover and frequency on sites burned by low-severity fires
were greater than on unburned or severely burned sites.  This effect was
greatest in post-fire year 2 [6].

On a prescribed burn in northeastern Minnesota, the frequency of
American vetch increased greatly on the burned areas during postfire
year 1 [1].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE :
