FIRE EFFECTS
SPECIES: Rosa woodsii | Wood's Rose 



IMMEDIATE FIRE EFFECT ON PLANT : 
Wood's rose is typically top-killed by fire [2,3,4,48].  Root crowns and
underground rhizomes survive low- or moderate-severity fires [7,21].
However, the shallow root crowns of Wood's rose are susceptible to
injury, and populations consequently decrease following high-severity
fire [3,21].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 



PLANT RESPONSE TO FIRE : 
Wood's rose recovery varies with fire severity.  Top-killed plants will
sprout from the root crown and underground surviving rhizomes
[9,17,34,52].  Reproduction from seed is rarely observed after fire.
When seedlings are observed in a burn area, their rate of growth is slow
compared to that of other species [51].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
In, Wood's rose doubled in abundance by postfire year 2 [33].  Following
a moderate- to high-severity fire at Manning Basin northeast of
Montpelier, Idaho, Wood's rose recovered to near preburn densities by
postfire year 2 [8].  The first growing season after a spring burn in an
aspen-conifer stand, west Boulder River, Montana, the density per acre
of Wood's rose showed significant increase.  The average height for
Wood's rose following the first postburn growing season was about half
or less of their average preburn height [19].  One year following a
high-severity fire in a northern Arizona ponderosa pine forest, postfire
biomass of Wood's rose was only about 0.25 that of prefire levels [46].


FIRE MANAGEMENT CONSIDERATIONS : 
NO-ENTRY
