FIRE EFFECTS
SPECIES: Rosa nutkana | Nootka Rose
IMMEDIATE FIRE EFFECT ON PLANT :
Nootka rose is top-killed by fire. Shallowly buried root crowns and
rhizomes of Rosa species, including Nootka rose, may be killed by severe
fire [14].
DISCUSSION AND QUALIFICATION OF FIRE EFFECT :
NO-ENTRY
PLANT RESPONSE TO FIRE :
Nootka rose may increase or decrease following fire. Rosa species of
British Columbia, including Nootka rose, usually initially decrease in
cover after wildfire. Cover gradually increases, and then declines
again as the canopy closes [14]. In a Douglas-fir/ninebark habitat type
in Idaho, Nootka rose cover was greater on burned sites or sites logged
and then burned than on undisturbed sites. Cover was less, however,
than on logged or grazed sites [7]. In aspen and aspen-mixed conifer
stands in Idaho and Wyoming, prescribed fires of low to high severity
caused a decrease in cover of Nootka and Wood's rose (Rosa woodsii) in
postfire year 1. Rose biomass in postfire year 2 was near prefire
levels [25]. In Washington and Oregon, burning had little effect on
abundance of Nootka rose. Multiple fires can significantly reduce cover
of rose species [14].
DISCUSSION AND QUALIFICATION OF PLANT RESPONSE :
NO-ENTRY
FIRE MANAGEMENT CONSIDERATIONS :
NO-ENTRY
