Book Description
Introduction to Forestry and Natural Resources, Second Edition, presents a broad, completely updated overview of the profession of forestry. The book details several key fields within forestry, including forest management, economics, policy, utilization and forestry careers. Chapters deal specifically with forest regions of the world, landowners, forest products, wildlife habitats, tree anatomy and physiology, and forest disturbances and health. These topics are ideal for undergraduate introductory courses and include numerous examples and questions for students to ponder. There is also a section dedicated to forestry careers. Unlike other introductory forestry texts, which focus largely on forest ecology rather than practical forestry concepts, this book encompasses the economic, ecological and social aspects, thus providing a uniquely balanced text. The wide range of experience of the contributing authors equips them especially well to identify missing content from other texts in the area and address topics currently covered in corresponding college courses. - Covers the application of forestry and natural resources around the world with a focus on practical applications and graphical examples - Describes basic techniques for measuring and evaluating forest resources and natural resources, including fundamental terminology and concepts - Includes management policies and their influence at the local, national and international levels

Book Description
Forest cover in most of the tropical countries is declining at an alarming rate. FAO in 1997 reported that with the exception of India, where there has been a small improvement, all tropical countries have lost forest cover during the period 1990-1995 (Schmidt, 2000). Though forest cover of India has increased to 20.55% of total geographical area (FSI, 2001), still there is a huge gap for achieving the target of 33% as laid down in National Forest Policy-1988. According to a rough estimate, out of total geographical area of 329 m ha of our country, more than 50 per cent of the area is under varying degree and form of soil erosion. About 5334 million tonnes of soil (16.35 t/ ha/ yr) is being eroded annually, of which 29% is permanently lost into the sea. About 5.37 to 8.40 million tonnes of soil nutrients are lost through water erosion (Anonymous,2003).

Book Description
Forest management is a complex process that now incorporates information obtained from many sources. It is increasingly obvious that the physiological status of the trees in a forest has a dramatic impact on the likely success of any particular management strategy. Indeed, models described in this book that deal with forest productivity and sustainability require physiological information. This information can only be obtained from an understanding of the basic biological mechanisms and processes that contribute to individual tree growth. This valuable book illustrates that physiological ecology is a fundamental element of proficient forest management. - Provides essential information relevant to the continuing debate over sustainable forest management - Outlines how modern tools for physiological ecology can be used in planning and managing forest ecosystems - Reviews the most commonly used forest models and assesses their value and future

Book Description
This book has been developed as a forest inventory textbook for students and could also serve as a handbook for practical foresters. We have set out to keep the mathematics in the book at a fairly non-technical level, and therefore, although we deal with many issues that include highly sophisticated methodology, we try to present first and foremost the ideas behind them. For foresters who need more details, references are given to more advanced scientific papers and books in the fields of statistics and biometrics. Forest inventory books deal mostly with sampling and measurement issues, as found here in section I, but since forest inventories in many countries involve much more than this, we have also included material on forestry applications. Most applications nowadays involve remote sensing technology of some sort, so that section II deals mostly with the use of remote sensing material for this purpose. Section III deals with national inventories carried out in different parts of world, and section IV is an attempt to outline some future possibilities of forest inventory methodologies.

Book Description
This new edition has been completely revised to provide up-to-date accounts of silvicultural practices, rural development issues, and the wider role that tree-planting plays. The chapters on agroforestry and protection forestry have been virutally rewritten, while throughout the book theimportant place of social forestry is recognized.
