An Analysis of Knowledge About Eucalyptus Plant in Iran and the World

Eucalyptus is one of the most important forest trees enjoying a unique fame in the world of plants. It is planted in large scale around the world and forms considerable forest masses. In today's world in which tree has become scarce even as a shade and sanctuary or in terms of landscape beauty due to prolonged and continuous exploitation as fuel or for construction and industrial works, the shortage can be offset by Eucalyptus cultivation due to its species diversity (six hundred species and variety), rate of growth and ecological flexibility. On the other hand, the major and minor products, short period between cultivating and fruition and high economic value of the Eucalyptus tree have attracted the attention of foresters and natural resource officials in different countries toward this plant and have led to its unprecedented rate of cultivation, so that, for example, Brazil has created about one million hectares of Eucalyptus forests, which is equivalent to about half the natural forests of northern Iran.
