Mycorrhizae promote fire adaptation in oak-hickory forests in Eastern USAThis article is part of a larger document. View the larger document here.
Prescribed fire is commonly used in silvicultural programs designed to promote oak (Quercus spp.) and hickory (Carya spp.) regeneration in eastern deciduous forests (Brose and others 2008). Thick bark, hypogeal germination, large root systems, repeated-prolific sprouting, and the ability to compartmentalize scars are well-known characteristics that enable oaks and hickories to tolerate fire (Burns and Honkala 1990) unlike certain mesophytic competitors including maples (Acer spp.), black cherry (Prunus serotina Ehrh.), and yellow-poplar (Liriodendron tulipifera L.).
