Preface
The success of any Professionals lies with the factor of assured employment in Government, non government and industrial sectors. The growing number of Professionals from multifarious organizations, have created significant competition among the graduates of various subjects. Forestry subject is of no exception. Being a narrow science, but offered almost several SAUs distributed across the country, it has created large number of Forestry Graduates. This resulted in competition and compelled the Forestry Graduates to acquire upto-date information in their subject for getting successful induction in public and private sectors. For being successful, one must be thorough in each and every aspects of the subject which demand a comprehensive book to resolve the issues.
Many competitive examinations conducted by state and central government organizations particularly TNPSC, UPSC and ICAR examinations are predominantly conducted through objective and subjective systems. For subjective examination wide range of books are available for the use by all competitors. However, for objective type examination, it is only very few books which again have not compiled the readymade information for each and every aspect of the subject. The voluminous of the subject often pose and threat to the examination which resulted in consuming more time and cost in search of the relevant materials.
Against this back drop, the first edition on Objective Forestry was conceived and published to benefit the forestry graduates who are preparing for the examinations like State Service Examination (Ranger, ACFs), UPSC (Preliminary exams), ARS (JRF, SRF and Scientist) and Bank exams., etc. This question bank incorporated several facets of Forest subjects extensively, which included Silviculture, Forest Mensuration, Forest Management, Forest Utilization, Wood Science and Technology, Forest Botany, Forest Genetics and Tree Breeding, Tree Physiology, Soil Science, Forest Microbiology, Forest Entomology, Forest Pathology, Wildlife, Ecology and Environment, Forest Laws and Policies and other additional and related informations on forestry.
The first edition on Objective Forestry has received wider attraction from all levels of stake holders. Many readers have indicated and suggested useful
corrections in the first edition. The authors profusely thank all the readers of the book. The authors specially thank Dr. P.S. Chauhan and Mohit Hussain of College of Horticulture and Forestry, Jhalawar (Rajasthan) and the faculty members of Forest College and Research Institute, TNAU for critically suggesting the corrections in the first edition of the book. The authors have taken enough care to carry out the corrections and also included a brief write-up cum technical notes for every chapter in their second edition which will benefit the readers of the book. Extending useful and constructive criticism and suggestion are most welcome for augmenting the contents and scope of publication in the future editions.
