Evaluation of site quality constitutes an essential§prerequisite for sustainable and economically§efficient forest management. Few methodologies for§mixed forests with indeterminate ages are known and§their application is often limited by regional§variations of factors determining tree growth.§In this study, site quality evaluation in subtropical§moist forests in north western Argentina was§investigated by applying classification schemes based§on various approaches. Different site characteristics§were related to growth data obtained from stem§analysis, soil and inventory data and canopy imagery,§using consumer grade digital photography.§Growth rates of Cedrela spp. were partially explained§by identifying correlated site factors. Soil§assessment allowed for assignment of explanatory§variables to distributions of quantitative stand§parameters and species composition. Analyses of§variances identified trends in distribution of§quantitative and qualitative stand parameters.§This article addresses foresters and scientists§working in subtropical forests and helps to§facilitate decision making with regard to site§quality, especially when facing low-information§scenarios.
