Synopsis The cultivation of forest trees passes through a long process and hence forms a complex net-work of the activities and needs a large number of terminologies to be explained in detail to bring out their full meaning. Thus, a need was felt to gather all possible information to compile the terms in the form of dictionary. A sincere effort has been made to exploit each and every term in its true sense and spirit. Throughout the text, the cross-references (cf) and the possible and appropriate synonymous (syn.) have also been cited to make it more comprehensive. In the support of the information gather, relevant bibliography has been given at the end of the text. It will help the readers for more details on the subject.
