“…Conceição et al (2012) De maneira geral, os valores médios de altura dominante foram superiores aos obtidos em povoamentos de Teca na Índia (UPADHYAY et al, 2005) e na Colômbia (TORRES et al, 2012), para os piores sítios. Aos 25 anos os sítios mais pobres apresentaram altura de 11,0 m em ambos os estudos, em relação aos 19,8 m obtido no presente estudo.…”

“…The height intervals were defined and given a specific range. Furthermore, a comparative analysis of the site index curves with other curves proposed by Upadhyay et al (2005) was conducted, employing the same methodology of superimposing data used in developing this study's model. The polymorphic equation used by this author was efficiently developed by Elfving and Kiviste (1998), Eq.…”

“…With regard to Tectona grandis, (teak), several studies on site index have been performed in countries as diverse as Tanzania (Malende and Temu, 1990), northern Ghana (Nunifu and Murchison, 1999), Costa Rica (Bermejo et al, 2004) and India (Upadhyay et al, 2005). In the state of Tabasco, Mexico, T. grandis is one of the most common plantation species.…”

The site index has been the predominant method used to evaluate forest stand productivity. Teak is one of the most accepted species within the international timber market due to the physical and aesthetic qualities of this wood. The aim of this study was to determine the site index of teak plantations. The study was conducted in teak plantations of Tabasco. Data were obtained from a network of 10 plantations consisting of 35 plots measured over four successive inventories (2003 to 2006). The data were fitted to five models, of which four were based on proposed finite difference equations and a non-integrated function. The most suitable of the five models was chosen, taking into account the goodness of fit, the residual analysis, and the validation with a data subsample from the plantation. The Sloboda model was finally selected, and the results obtained were compared with the model proposed by Upadhyay. This model proved to be a useful tool, not only in evaluating station quality but also in improving the planning and management of teak plantations in Tabasco.

“…Permanent sample plots (PSPs) were also laid out in various parts of India for tree growth and yield studies to develop growth and yield models based on the data collected from these plots (e.g., Kumar et al 1995;Jayaraman and Lappi 2001;Upadhyay et al 2005;Tewari 2011). …”

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.
