[Termes IGN] juniperus phoeniceaRésumé : (auteur) [introduction] [...] In the French Mediterranean region, populations of this Juniper tree can also grow on vertical and exposed limestone cliffs. Larson et al. (1999, 2000) assigned to cliffs the property of supporting ancient, primary or virgin woodland. In such habitats, disturbances from humans are absent, due to inaccessibility. Trees also benefit of absence of fires, grazing and competition by more aggressive level-ground vegetation. On these cliffs, in the southeast of France, Juniperus phoenicea is adapted to extreme growing conditions where the main constraints are verticality and compact hard limestone constituting a strong mechanical stress on roots. Indeed it limits their growth and both nutrients and water supply in dry and warm conditions under Mediterranean climate. In addition to that, trees face sporadic rockfall.
