FIRE EFFECTS

SPECIES: Cornus nuttallii | Pacific Dogwood
IMMEDIATE FIRE EFFECT ON PLANT : Due to the thin bark of Pacific dogwood the immediate effect of a cool to moderate burn is damage to the cambian layer resulting in top-kill of the tree [6,12]. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Pacific dogwood sprouts vigorously from dormant buds on the root crown after cool to moderate burns [12]. The number of suckers per stump is directly proportional to stump size [32]. Roy [27] investigated hardwood sprouting in California after clearcutting and broadcast burning. The mean height, crown diameter, and sprouts per plant in postfire years 2 and 3 were as follows: Post fire Height Crown Diameter Sprouts Year 2 4.2 feet 4.5 feet 19 (1.3 m) (1.36 m) Year 3 5.9 feet 5.4 14 (1.7 m) (1.6 m) Schoonmaker and McKee [31] studied long-term secondary succession in the coniferious forests of the Cascades. They found that percent cover of Pacific Dogwood after 40 years exceeds that of old growth. Pacific dogwood will invade clearcuts and burns from adjacent forests from dissemination of seeds by birds and small mammals [39]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : If one of the management goals of a prescribed fire is preservation of Pacific dogwood for aesthetic value (as in the giant sequoia groves), a fire line should be prepared around Pacific dogwood [6]. When Pacific dogwood is overtopped by conifers and becomes decadent, as in the case of the disjunct population in Idaho, a prescribed fire is recommended for rejuvenation [24].
