The eucalyptus is a native Australian tree.The name "eucalyptus" comes from the Greek eu, meaning "well", and kalyptos, meaning "cover." [41] In a National Park Service study, it was found that the fuel load (in tons per acre) of non-native eucalyptus woods is almost three times as great as native oak woodland.[41]. [96] This, their rapid growth in the Italian climate and excellent function as windbreaks, has made them a common sight in the south of the country, including the islands of Sardinia and Sicily. A marlock is a shrub or small tree with a single, short trunk, that lacks a lignotuber and has spreading, densely leafy branches that often reach almost to the ground.

Fast growth also makes eucalypts suitable as windbreaks and to reduce erosion. [citation needed] Although eucalyptus trees are seemingly well-defended from herbivores by the oils and phenolic compounds, they have insect pests. [citation needed], Four leaf phases are recognised in the development of a eucalyptus plant: the ‘seedling’, ‘juvenile’, ‘intermediate’, and ‘adult’ phases.
