Mixed and monospecific stands of Eucalyptus and black-wattle. II - Fine root boimass density
(2015)The aim of this study was to evaluate fine root biomass density (FRBD) in mixed and monospecific stands of Eucalyptus grandis x E. urophylla and Acacia mearnsii (black wattle) in Bagé-RS (Southern Brazil). An experimental ... -
Modeling extreme values for height distributions in Pinus pinaster, Pinus radiata and Eucalyptus globulus stands in northwestern Spain
(Italian Society of Silviculture and Forest Ecology (SISEF), 2015)Methods of estimating extreme height values can be used in forest modeling to improve fits to the marginal distribution of heights in the following bivariate diameter-height models: the SBB Johnson’s distribution, the ... -
Modelling the vertical distribution of canopy fuel load using national forest inventory and low-density airbone laser scanning data
(Public Library of Science, 2017-04-27)The fuel complex variables canopy bulk density and canopy base height are often used to predict crown fire initiation and spread. Direct measurement of these variables is impractical, and they are usually estimated ... -
Modelo de distribución de la carga de combustibles finos en el dosel de copas de rodales regulares de "Pinus Pinaster": efecto de claras combinadas con podas
(Sociedad Española de Ciencias Forestales, 2012)Los modelos de predicción del riesgo de inicio y propagación de fuegos de copas requieren conocer, entre otros parámetros, la altura de la base de la cubierta de copas (CBH) y la densidad aparente del combustible en la ... -
National-scale assessment of forest site productivity in Spain
(Elsevier, 2018-05-15)Sustainable production of wood is one of the main services provided by forest systems. Site productivity in the case of forests is often evaluated through the site quality. However, most of the works addressing the site ... -
A new approach to defining rotation ages on the basis of productive and technological aspects. Application to natural Pinus sylvestris L. stands in Central Spain
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2017)Aim of study: To propose a new approach to defining rotation ages on the basis of productive and technological aspects and to present an example of application of the methodology to natural Pinus sylvestris stands in ... -
Novel approach to assessing residual biomass from pruning: A case study in Atlantic Pinus pinaster Ait. timber forests
(Elsevier, 2017)Forestry residual biomass from pruning operations is an important, though little studied, potential resource. Residues normally remain in the stand, since tools for their accurate quantification do not exist and it has no ... -
Nutrient Contribution of Litterfall in a Short Rotation Plantation of Pure or Mixed Plots of Populus alba L. and Robinia pseudoacacia L.
(MDPI, 2020)This study aims to quantify the potential contribution of nutrients derived from leaf litter in a short rotation coppice plantation which includes monocultures of the species Populus alba (PA) and Robina pseudoacacia (RP) ... -
Nutritional prescriptions for Eucalyptus plantations: lessons learned from Spain
(MDPI, 2016-04-15)Eucalyptus globulus Labill is the main exotic broadleaf species planted and managed for pulp and energy production in Spain, where it covers an area of more than 0.6 million ha. The climatic and soil conditions of the ... -
Poplar Short Rotation Coppice Plantations under Mediterranean Conditions: The Case of Spain
(MDPI, 2020)Developing a circular bioeconomy based on the sustainable use of biological resources, such as biomass, seems to be the best way of responding to the challenges associated with global change. Among the many sources, short ... -
Selección de criterios sociales y ambientales para la delimitación de núcleos rurales en Galicia, España
