FIRE ECOLOGY

SPECIES: Chamaedaphne calyculata | Leatherleaf
FIRE ECOLOGY OR ADAPTATIONS : Leatherleaf's persistence in communities over long periods of time has been attributed to its regeneration following fire [17]. Its rhizomes are buried deep in the mineral soil and survive all but the most severe fires [26]. Depth of rhizomes and season of fire affect leatherleaf shoot growth and recovery. Leatherleaf rhizomes were collected in spring, summer, and autumn and subjected to wet heat treatments from 113 to 140 degrees Fahrenheit (45-60 deg C). All autumn-collected rhizomes died after treatment. Summer-collected rhizomes produced fewer shoots than spring-collected; both had significantly (p<0.05) fewer shoots than the controls [27]. Bogs are usually too wet to burn except during drought [56]. Fire is a primary factor disrupting boreal treed bog succession; leatherleaf invades after fires remove the tree associations [9,22,28,33]. Recurrent fires at approximately 50-year intervals in New England leatherleaf bogs or on peat surfaces controls tree invasion [53]. Fire recurrence in a New Brunswick bog was 370 years [28]. POSTFIRE REGENERATION STRATEGY : Rhizomatous low woody plant, rhizome in organic mantle Surface rhizome/chamaephytic root crown Rhizomatous shrub, rhizome in soil Secondary colonizer - off-site seed
