FIRE EFFECTS

SPECIES: Chamaedaphne calyculata | Leatherleaf
IMMEDIATE FIRE EFFECT ON PLANT : Fire top-kills leatherleaf. Leatherleaf probably survives severe fires because rhizomes are deep in water-saturated substrates and its stems are matted in debris [28,33]. Surviving root crowns and rhizomes sprout. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Leatherleaf was only slightly injured by summer or autumn fires in New Brunswick. Following spring burning, leatherleaf showed a strong increase in stem density; apparently, it had not yet depleted its reserves and was able to support new growth. Preburn and postburn percent relative abundance (stem density) after spring, summer, and autumn fires was as follows [26,29]: Season of Postburn burn Preburn 1 month 3 months 5 months -------------------------------------------------------------------- Spring 28 42 13 -- Summer 30 29 29 17 Autumn 36 32 -- -- Ten years after a lightning fire in Alaska, leatherleaf was present in low amounts on disturbed firelines and in one burned site [80]. It was present at 0.7 percent frequency in burned and at 2 percent frequency in unburned areas 20 to 24 years following fire in the Northwest Territories [45]. In northern Quebec, leatherleaf occurred 30 years after fire at 21 to 31 percent frequency in lowland boreal black spruce forest and at 1 to 20 percent in forest-tundra sites [72]. Leatherleaf had about 40 percent frequency 94 years following a high-severity fire in central New York [50]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : Leatherleaf is a flammable shrub; crowning or foliage scorch is common with leatherleaf in the understory in the pine swamps or lowlands of New Jersey [52]. Fuel loading that was predominantly leatherleaf and bog labrador tea in cutover areas of black spruce was estimated at 15 to 25 tons per acre (33-56 t/ha) in the Blackduck Burns, Minnesota [40].
