lignotubers

“They can send up new coppice shoots, as mallee does in the Whipstick, from underground lignotubers, and their roots plunge far too deep to be burnt.”

“Consequently, fire is an important large-scale process impacting on biodiversity, and many plant species possess characteristics such as seritony, protected vegetative buds, lignotubers, and soil seedbank that enable populations to persist.”

Murray-Darling woodlands and mallee

“Although now extensively cleared for agriculture (predominantly cereal cropping and pasture), the region was originally vegetated with mallee woodlands, a distinctive multi-stemmed growth form emanating from the large lignotubers of Eucalyptus spp. that comprise the tree layer.”
