Assessing site form as an indicator of site quality in even-aged Pinus radiata D. Don stands in north-western Spain
(Springer, 2019)Key message: Site form and site index have shown similar precision for estimating site quality in even-aged Pinus radiata D. Don stands in north-western Spain. Additionally, SF presents the advantage that it does not ... -
Assessing site quality using the National Forest Inventory
(2017-06-28)Site productivity of forests is often evaluated thorough the site quality. Different indices can be used to measure site quality but the site index (relationship between dominant height and age) is the most employed. ... -
Assessing the effect of pruning and thinning on crown fire hazard in young Atlantic maritime pine forests
(Elsevier, 2018)Management of fuel to minimize crown fire hazard is a key challenge in Atlantic forests, particularly for pine species. However, a better understanding of effectiveness of silvicultural treatments, especially forest pruning, ... -
Carbon balance for different management practices for fast growing tree species planted on former pastureland in southern Europe: a case study using the CO2Fix model
(Springer, 2012)Although it is known that forestry mitigates carbon emissions to some degree, there is still a need to investigate the extent to which changes in forest management regimes affect the carbon cycle. In a climate-change ... -
Cartografía de variables dasométricas en bosques Mediterráneos mediante análisis de los umbrales de altura e inventario a nivel de masa con datos LiDAR de baja resolución
(Universitat Politécnica de Valéncia, 2016)Este estudio presenta avances en la metodología de inventario forestal a nivel de masa (area-based approach, ABA) con datos LiDAR aerotransportado de baja densidad y destaca la utilidad de los datos LiDAR disponibles para ... -
Comparing Johnson’s SBB, Weibull and Logit-Logistic bivariate distributions for modeling tree diameters and heights using copulas
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2016)Aim of study: In this study we compare the accuracy of three bivariate distributions: Johnson’s SBB, Weibull-2P and LL-2P functions for characterizing the joint distribution of tree diameters and heights. Area of study: ... -
Comparison of ALS based models for estimating aboveground biomass in three types of Mediterranean forest
(Taylor & Francis, 2017-02-17)This study aimed to develop ALS-based models for estimating stem, crown and aboveground biomass in three types of Mediterranean forest, based on low density ALS data. Two different modelling approaches were used: (i) ... -
A comparison of estimation methods for fitting Weibull, Johnson’s SB and beta functions to Pinus pinaster, Pinus radiata and Pinus sylvestris stands in northwest Spain
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2012)The purpose of this study was to compare the accuracy of the Weibull, Johnson’s SB and beta distributions, fitted with some of the most usual methods and with different fixed values for the location parameters, for describing ... -
Compatible Taper and Volume Systems Based on Volume Ratio Models for Four Pine Species in Oaxaca Mexico
(MDPI, 2021)Estimating tree volume components is an essential element in sustainable forest management. Compatible taper and merchantable outside-bark volume systems based on volume ratio models were globally fitted to four pine species ... -
Crecimiento y distribución de biomasa aérea en clones de castaño híbrido a edad temprana
(Sociedad Española de Ciencias Forestales, 2016)Se presentan los resultados de la medición en 228 ejemplares de castaños híbridos de 20 clones distintos en vivero, de edades comprendidas entre 4 y 7 años. Se realizaron muestreos destructivos para caracterizar las ... -
Delimiting the spatio-temporal uncertainty of climate-sensitive forest productivity projections using Support Vector Regression
(Elsevier, 2021)As climate change makes many traditional empirical growth approaches not functional for forest dynamics modelling, new climate-sensitive models are needed. However, using these newly developed models for extrapolation, ... -
Dynamics of land use and land cover in a Mexican national park
(Instituto de Ecología, A.C., 2017-11-18)To understand the dynamics of land cover at the Parque Nacional Cofre de Perote, the rates of change in land use were compared at two different scales during the period 1995-2004. At the meso scale, these patterns were ... -
Effect of soil storage at 4 °C on the calorespirometric measurements of soil microbial metabolism
