Determining the site index of Teak (Tectona grandis L.) plantations in Tabasco, Mexico

Abstract Forest stand productivity is defined as the quantitative estimation of a specific area's potential to produce biomass over a determined period of time. The site index has been the predominant method used to evaluate forest stand productivity. Teak is one of the most accepted species wi...
