Abstract Sustainable forest management requires decision support systems to evaluate possible scenarios and anticipate the consequences of decisions. Forest modellers typically develop complex systems of equations to predict the behaviour of forests which makes the use of forest models difficult for end-users in general, affecting transfer of knowledge and technology. To overcome these difficulties and facilitate their practical use, models can be integrated into software to generate user-friendly forest simulators. In this paper we introduce and describe ForestMTIS, a cloud computing compiled and editable open-source project to generate forest simulators which was developed for statistical, non-spatial, deterministic, disaggregated, single species even-aged stand growth and yield models. We demonstrate the use of ForestMTIS based on the development of FlorNExT®, its first practical application, based on a collaborative approach to make growth and yield modelling and sustainable forest management available to a large community of users in the Northeast of Portugal.

En este trabajo se ha estudiado la evolucion de la biomasa y del carbono acumulado en los arboles de Quercus robur presentes en Galicia (noroeste de Espana). Se desarrollaron ecuaciones de estimacion de biomasa para arbol individual, las cuales utilizan como variable independiente el diametro normal. Se realizo un ajuste simultaneo para garantizar la aditividad, y se empleo la metodologia GMM (generalized method of moments) debido a la presencia de heterocedasticidad. Para estimar la evolucion de la biomasa de Q. robur en Galicia, las ecuaciones desarrolladas se aplicaron a los datos del numero de arboles por clase diametrica de los cuatro inventarios forestales nacionales (IFN) realizados hasta el momento. La concentracion media de carbono en los diferentes componentes arboreos considerados permitio estimar el carbono acumulado a partir de la biomasa. Aunque en Galicia ha disminuido la superficie de bosques puros de Q. robur, la evolucion del numero de arboles ha sido positiva en el periodo considerado (1972-2009). La evolucion de la biomasa y del carbono acumulado por esta especie tambien ha sido positiva en este periodo, pasando de 12.209.663 Mg de biomasa arborea en 1972 a 40.333.571 Mg en 2009, que se corresponde con 5.878.971 Mg y 19.415.955 Mg de carbono, respectivamente.
