Annual Course of Litter Fall in Eucalyptus camaldulensis Dehn. In Israel

Abstract

The seasonal course of litter fall in Eucalyptus camaldulensis is described. The peak of leaf shedding (40,7% of the annual total) occurred in April-May. Maximal shedding of bark and twigs (47,3% and 36,7% respectively of the annual total) was found in November-December. It seems that spring leaf shedding was induced by atmospheric stress brought on by low air humidity and high temperature. Litter fall in late autumn was influenced by both atmospheric stress and strong winds. The total annual dry weights of the litter components (g/m²) were: leaves, 737; twigs, 196; bark, 92.
