Aim of study: Although beech (Fagus sylvatica L.) forests in north-western Spain constitute c.a. 40% of the total area occupied by the species in the whole country, no growth or yield studies have been carried out regarding these forests. The specific objective of this study was to elaborate yield tables and stand density management diagrams for th...

De acuerdo con el Tercer Inventario Forestal Nacional, los hayedos ocupan una superficie aproximada de 388.000 ha en España, de las cuales las masas asturleonesas constituyen aproximadamente el 40% (DGCN, 2006). En la Cordillera Cantábrica, el haya es la especie climácica en altitudes superiores a 600 m sobre el nivel del mar (Gandullo et al., 2004...

The European beech (Fagus sylvatica L.) occurs in the Cantabrian Range (NW Spain), at the southwestern limit of the wide distribution area of the species in Europe, forming relatively unmanaged forests of high biodiversity value. In this study, we measured three-dimensional positions, diameter at breast height and height of all the trees present in...

Planting eucalypt stands in the Iberian Peninsula is controversial. In Galicia (NW Spain) the area covered by eucalypts and the intensity of eucalypt timber harvesting are among the highest in Europe. In this region, management plans for forest resources are intended for relatively homogeneous territorial units, smaller than the province, called fo...

El pino pinaster es una especie forestal con gran versatilidad ecológica que en la Península Ibérica ha sido clasificada tradicionalmente en dos poblaciones o subespecies diferentes: atlántica y mediterránea. Las poblaciones españolas de pino pinaster atlántico parece que se expandieron a través de Galicia durante el siglo XIX procedentes de Portug...

The goals of this study were to analyze the current status of eucalypt plantations in northern Spain and to assess current and future potential expansion of these plantations under climate change. The findings showed that the area occupied by Eucalyptus globulus has increased greatly (by 4.6 times) in northern Spain in the last 50 years, to reach t...

El género eucalipto fue introducido en Europa a finales del siglo XVIII con fines ornamentales (Silva-Pando y Pérez-Pino, 2016), aunque su buena adaptación a las condiciones del sur del continente propició su rápida plantación en terrenos forestales. La primera plantación en España, fue probablemente con Eucalyptus globulus y está datada en Galicia...

Bioenergy plantations have been emerging around the world in the last decades. Accurate prediction of biomass feedstocks is necessary to optimise forest management for bioenergy production. Biomass increment estimations in plantations could be obtained from historical tree diameter reconstructions based on tree-ring records (Babst et al., 2014). Pr...

A model was developed for predicting current and future disaggregated volume, biomass and carbon stocks in even-aged pedunculate oak (Quercus robur L.) stands in Galicia (northwestern Spain). In the model, the stand state at any point in time is defined by age (A), dominant height (H), number of trees per hectare (N) and stand basal area (G). A dyn...

Site index is the most common measure of forest site productivity used worldwide, serving as an important baseline for forest-level planning and helping to formulate silviculture strategies. Site index is usually obtained through measurement of dominant height and stand age. However, age is not available in many cases, such as in most national fore...

Forty young trees from a stand of maritime pine in the southern mountains of Galicia, Spain (42°21′N: 8°01′W) were felled to obtain the material required for studying density and shrinkage in clear and small wood specimens. The wood ranged from light to moderately heavy, and the dimensions remained reasonably stable with varying moisture content. T...

Measuring the height of a tree takes longer than measuring its diameter at breast height and often only the heights of a subset of trees of known diameter are measured in forest inventories. Since trees with the same diameter are not usually of the same height, even within the same stand, a stochastic component was added to the deterministic height...
