Functional adaptationUnderground storage enables regeneration: jarrah trees
Jarrah trees are able to regenerate after fire thanks to an underground root swelling that stores carbohydrates and contains potential bud-forming sites.
"'Mallee' eucalypts are characterized by multiple woody stems arising from an underground lignotuber (Kerr, 1925; James, 1984). The latter houses a large store of potential bud-forming sites carrying the capacity for rapid regeneration of a canopy after decapitation. A lignotuber typically contains several thousand of such 'meristemic foci' (Noble, 2001), each of which is capable of producing several individual shoots (Noble, 1989; Burrows, 2000, 2002)." (Wildy and Pate 2002:185)
