Rhizina undulata on Picea abies transplants

摘要

AbstractAt least three quarters of the sites of brash fires in a mainly coniferous area on peat in Co Tyrone, Northern Ireland were clonised byRhizina undulata. On each of these sites an average of eight newly plantedPicea abiesdied within five years. No more deaths were recorded during a further three years. Deaths ofPicea abiesseldom occurred where there had been no fire or on fire sites on hardwood stumps in the same area.
