“…There was a countrywide concerted effort for laying out linear tree increment plots, subsequent to a resolution in the Third Silvicultural Conference in Dehradun in 1929. Many of these sites are in degraded conditions and maintenance work of most sites is rather poor (Tewari et al 2014). There is a need to stimulate proper maintenance and upkeep of these sites which are invaluable for forestry research.…”

“…Species richness, evenness, species diversity, and importance value index (IVI) are calculated to observe diversity and structure in the forests. These traditional methods of measuring diversity are based on concepts developed during the 1960s, at a time when computer software was in its infancy and effective analytical tools were not available (Tewari et al 2014). …”

“…The most important difference to the TCP approach is the fact that each tree is identified by a number and by its x and y coordinates. Numbers are permanently painted on the trees to allow re-identification of individuals at successive remeasurements in the field, thus creating a basis for spatially explicit analysis of forest structure and diversity, and for studying the effects of competition and forest dynamics (Tewari et al 2014).…”

“…Afterwards, re-measurements are less costly while the value of the information continues to increase with each re-measurement. One important advantage of TRP studies is the fact that it is possible to measure spatial variations in density and species composition, and therefore to infer competition effects on individual tree growth and stand dynamics (Tewari et al 2014). Although TCP data is more limited than TRP data for some detailed analysis, some synergies may evolve to balance the common parameters such that TCPs can be used to extend the utility or inference associated with the more expensive TRP plots.…”

National forest assessments are attracting increasing attention owing to their role in providing information related to manifold forest functions. Large-area information is in high demand, both for the forest in its role as ecosystem and in its role as resource and service provider. Of particular current interest are forest assessment systems at national level by countries that wish to engage in the REDDC initiative. Large-area forest monitoring has never had a prominent place on the curricula of forestry faculties in India or many other tropical countries. As a consequence, in many tropical countries, there is only very limited technical capacity for large-area forest monitoring. The discipline of "forest inventory" has developed a versatile toolbox of techniques and methods useful for national level assessments, and remote sensing technology has, over the last few decades, added some exciting options to this toolbox. This article analyzes the process of national forest monitoring and identifies key areas where national capacity may be developed. A brief description of forest assessment in India, long-term observational studies, and synergy with the national forestry inventory is also presented.
