A stand density management diagram (SDMD) was constructed for Pinus radiata D. Don plantations in Galicia (north-western Spain) on the basis of four equations that were fitted simultaneously to data collected from 223 permanent plots. The relative spacing index used characterize growing stock. provides information about quadratic mean diameter, merchantable volume, above-ground biomass, stem biomass and carbon pools. In addition, an estimation average slenderness coefficient whole each...
Three types of forest stands (chestnut coppice, maritime pine stands, and poplar willow short-rotation woody crops (SRWC)) were evaluated to determine their potential for energy production. The properties the main aboveground biomass fractions (wood, bark crown) also whole tree analysed, thus providing data that could be used management purposes evaluating forest, yields atmospheric emissions. Proximate, elemental energetic analyses provided important information fuel potential. value...
A basal area growth system for single-species, even-aged maritime pine (Pinus pinaster Ait.) stands in Galicia (northwestern Spain) was developed from data of 212 plots measured between one and four times. Six dynamic equations were considered analysis, both numerical graphical methods used to compare alternative models. The double cross-validation approach assess the predictive ability best described by a equation derived Korf function using generalized algebraic difference (GADA)...
Accurate forest monitoring is critical for achieving the objectives of European Green Deal. While national inventories provide consistent information on state forests, their temporal frequency inadequate fast-growing species with 15-year rotations when are conducted every 10 years. However, Earth observation (EO) satellite systems can be used to address this challenge. Remote sensing satellites enable continuous acquisition land cover data high (annually or shorter), at a spatial resolution...
Foresters may require to estimate the diameter at breast height (d.b.h.) and volume of trees that have been cut, only available stumps as an indicator size trees. In present study, equations for predicting both d.b.h. from stump inside bark were developed major pine species in forest region El Salto, Durango (Mexico). The was estimated with relatively high accuracy a simple linear model. tree also precision by use allometric equation. Weighted non-linear least squares methods used take into...
A generalized height–diameter (h-d) model was developed in order to predict the total height of individual trees uneven-aged stands region El Salto, Durango (Mexico). Seven h-d equations were evaluated and equation proposed by Sharma Parton, which includes diameter at breast tree quadratic mean dominant stand as independent variables, selected best model. In address among-plot variability, a non-linear mixed-effects modelling approach used fit for all species or groups species. The mixed...
In this paper we present a review of forest models developed in Spain recent years for both timber and non production dynamics (regeneration, mortality,..). Models are whole stand, size (diameter) class individual-tree. The to date have been using data from permanent plots, experimental sites the National Forest Inventory. show different sub-models so far friendly use software. Main perspectives modelling presented.
The prediction of growing stock volume is one the commonest applications remote sensing to support sustainable management forest ecosystems. In this study, we used data from 4th Spanish National Forest Inventory (SNFI-4) and 1st nationwide Airborne Laser Scanning (ALS) survey develop predictive yield models for three major commercial tree species (Eucalyptus globulus, Pinus pinaster radiata) grown in north-western Spain. Integration both types required prior harmonization because differences...
In this study, we used Spanish National Forest Inventory (SNFI) data, Sentinel-2 imagery and ancillary data to develop models that estimate forest variables for major commercial timber plantations in northern Spain. We carried out the analysis two stages. first stage, considered plots with without sub-meter geolocation, three pre-processing levels images machine learning algorithms. most cases, geometrically, radiometrically, atmospherically topographically (L2A-ATC) corrected random...
This study examined the effect of atmospheric, topographic, and Bidirectional Reflectance Distribution Function (BRDF) corrections Sentinel-2 images implemented in Google Earth Engine (GEE) for use land cover classification. The was carried out an area complex orography northern Spain made Spanish National Forest Inventory plots other systematically located to non-forest classes. A total 2991 photo-interpreted ground 15 images, acquired summer at a spatial resolution 10–20 m per pixel, were...
Density management is the usual method used by silviculturists to achieve a desired future stand condition, and one of most effective methods design, display evaluation alternative density regimes in even-aged stands use diagrams. In present study, we describe for developing thinning schedules pedunculate oak (Quercus robur L.) Galicia (north-western Spain), using diagram. The diagram integrates relationships among density, dominant height, quadratic mean diameter volume single graph. data...
