Farm forestry plantations have acquired increasing importance in the recent past for their role not only in meeting the material requirements but also for their ecological and environmental functions. Plantations by individuals or plantations carried out by Industries have taken important place in maintaining the ecological and environmental balance. Plantations not only play an important role in natural resource management but also provide raw materials for pulping and other engineering works. Monitoring of such plantation is a basic problem faced by different industries, so it is vital to keep track of felling, planting and timely prediction of wood availability. Therefore, accurate and updated information on forest resources is of paramount importance. Satellite remote sensing plays an important role in generating information about the latest land use-land cover pattern in an area and its temporal changes through times. Satellite remote sensing provides a mean to obtain a synoptic view of forests and their condition on real time basis. The standardization of ground sampling methods, understanding of spectral and temporal responses of vegetation, coupled with the recent advancements in digital image processing techniques have brought about a profound acceptance of the application of satellite remote sensing data in forest inventory and mapping. The information being in digital form can be brought under Geographical Information System (GIS) to provide a suitable platform for data analysis, update and retrieval.Speck Systems Limited, Hyderabad conducted a satellite data based survey for estimation of Eucalyptus and Poplar plantation in selected Northern States of India. Species wise plantation maps for the years 2000 and 2005 were prepared at 1:50,000 scale and district wise statistics for the planted area was generated. Change detection techniques were used to quantify the dynamics of plantation cover over the period of five years. Field surveys were conducted in the project area to collect information on wood yield and felling cycles. This information was integrated with the spatial distribution of plantations and analysed on a GIS platform to estimate plantation wood availability predicted for each project district.
