FIRE EFFECTS AND USE
WILDLIFE SPECIES: Canis latrans | Coyote 



DIRECT FIRE EFFECTS ON ANIMALS : 
Coyotes are very mobile and can probably escape most fires.  There are
no reports of direct coyote mortality due to fire [49].


HABITAT RELATED FIRE EFFECTS : 
Fire may improve the foraging habitat and prey base of coyotes.  In New
Enlgand, coyotes are commonly found in forest openings created by fire
or logging [18].  Fires that reduce vegetation height and create open
areas probably increase hunting efficiency by coyotes.  Surface fires
often open substrates for quieter stalking and easier capture of prey
than can occur in closed forests [38].  Wirtz [68] noted increases in
consumption of birds and deer by coyotes after a chaparral fire in the
San Dimas Experimental Forest, California.  Increased consumption was
presumably the result of increased vulnerability of prey with reduced
cover, but no change was noted in small mammal consumption.

Periodic fire helps to maintain habitat for many prey species of coyote.
Fires that create a mosaic of burned and unburned areas are probably the
most beneficial to many coyote prey species.  Several studies indicate
that many small mammal populations increase rapidly subsequent to
burning in response to increased food availability.  Fire often improves
hare and rabbit forage quality and quantity for two or more growing
seasons [38].  Hill [67] concluded that burning at intervals longer than
2 years would be less beneficial to rabbits and hares, but any fire is
believed better than fire exclusion.  Along the coast of northern
California, black-tailed jackrabbits occurred at highest density in open
brush, moderate density on recent burn areas, and lowest density in
mature chaparral stands [68].  Wagle [65] reported that fire suppression
in grasslands is detrimental to populations of small bird and mammal
herbivores due to organic matter accumulation and reduced plant vigor.

The 1988 fires in Yellowstone National Park have probably benefited
coyotes.  Fire in combination with drought likely increased available
carrion the fall and winter following the fire.  Additionally, the fires
stimulated grass production, which should lead to an increase in small
mammal populations [45].
   
In California, coyotes are abundant in young chaparral (less than 20
years old) and are rare or absent in chaparral that has not been burned
for 20 years or more [51].  Quinn [51] observed more coyote sign during
the second and third years after a chamise (Adenostoma spp.) chaparral
wildfire in Riverside County than had been observed prior to burning.
Coyote numbers increased during the second and third years following a
chaparral fire in the Sierra Nevada foothills [39].


FIRE USE : 
Prescribed burning that favors small mammals by creating ecotones and
different age classes of vegetation would increase the prey base for
coyotes and make hunting easier by opening up the habitat [51].
