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. ...
Potential of Sentinel-2A data to model surface and canopy fuel characteristics in relation to crown fire hazard
(MDPI, 2018)
Background: Crown fires are often intense and fast spreading and hence can have serious impacts on soil, vegetation, and wildlife habitats. Fire managers try to prevent the initiation and spread of crown fires in forested ...
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 ...
Modelling canopy fuel and forest stand variables and characterizing the influence of thinning in the stand structure using airborne LiDAR
(Universitat Politécnica de Valéncia, 2016)
Forest fires are a major threat in NW Spain. The importance and frequency of these events in the area suggests the need for fuel management programs to reduce the spread and severity of forest fires. Thinning treatments ...
Species-specific and regional volume models for 12 forest species in Durango, Mexico
(Universidad Autónoma Chapingo, 2017)
Introduction: Estimating the volume of individual trees is an important aspect in dendrometry and in the conducting of forest inventories.
Objective: Significant differences were evaluated in additive equation systems for ...
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 ...
Evaluation of Radiometric and Atmospheric Correction Algorithms for Aboveground Forest Biomass Estimation Using Landsat 5 TM Data
(MDPI, 2016-04-29)
Solar radiation is affected by absorption and emission phenomena during its downward trajectory from the Sun to the Earth’s surface and during the upward trajectory detected by satellite sensors. This leads to distortion ...
Mapas nacionales de calidad de estación para Pinus sylvestris, Pinus nigra, Pinus pinaster, Fagus sylvatica y Quercus pyrenaica
(Asociación y Colegio Oficial de Ingenieros Técnicos Forestales y Graduados en Ingeniería Forestal y del Medio Natural, 2018)
La determinación de la calidad de estación de un rodal es fundamental para poder establecer una gestión sostenible de los recursos. La mayor parte de los trabajos que estudian las variables que explican la calidad de ...
Compatible System for Predicting Total and Merchantable Stem Volume over and under Bark, Branch Volume and Whole-Tree Volume of Pine Species
(MDPI, 2017)
Accurate quantification of branch volume in trees is important for sustainable forest
management, especially as these fractions are increasingly used for bioenergy, and for precise
forest CO2 quantification. Whereas a ...
Development of a Compatible Taper Function and Stand-Level Merchantable Volume Model for Chinese Fir Plantations
(PLOS, 2016-01-22)
Chinese fir (Cunninghamia lanceolata [Lamb.] Hook) is one of the most important plantation tree species in China with good timber quality and fast growth. It covers an area of 8.54 million hectare, which corresponds to 21% ...
