Recently, there have been significant advances in the use of terrestrial laser scanning (TLS) instruments, which facilitate the capture of detailed forest structure. However, for tree species recognition the structural information from TLS has mainly been used to complement spectral information. TLS-only classification studies have been limited in size and diversity of plot forest types. In this paper, we investigate the potential of TLS for tree species classification. We used quantitative structure models to determine 17 structural tree features. These features were computed for 758 trees of five tree species, including two understory species, of a 1.4 hectare mixed deciduous forest plot. Three classification methods were compared: k-nearest neighbours, multinomial logistic regression and support vector machine. We assessed the potential underlying causes for structural differences with principal component analysis. We obtained classification success rates of approximately 80%, however, with producer accuracies for three of the five species ranging from 0 to 60%. Low producer accuracies were the result of a high intra- and low inter-species variability. These effects were, respectively, caused by a high size-dependency of the structural features and a convergence of structural traits across species as a result of the individual tree position in the forest canopy and shade tolerance. Nevertheless, the producer accuracies could be improved through sensitivity vs. specificity trade-offs, with over 50% for all species being obtainable. The high intra -and low inter-species variability complicate the classification. Furthermore, the classification performance and best classification method greatly depend on its targeted application. In conclusion, this study proves the added value of TLS for tree species classification but also shows that TLS opens up potential for testing and further development of ecological theory.

[Vedettes matières IGN] Inventaire forestierRésumé : (auteur) The demand for precise mapping and monitoring of forest resources, such as above ground biomass (AGB), has increased rapidly. National accounting and monitoring of AGB requires regularly updated information based on consistent methods. While remote sensing technologies such as airborne laser scanning (ALS) and digital aerial photogrammetry (DAP) have been shown to deliver the necessary 3D spatial data for AGB mapping, the capacity of repeat acquisition, remotely sensed, vegetation structure data for AGB monitoring has received less attention. Here, we use vegetation height models (VHMs) derived from repeat acquisition DAP data (with ALS terrain correction) to map and monitor woody AGB dynamics across Switzerland over 35 years (1983-2017 inclusive), using a linear least-squares regression approach. We demonstrate a consistent relationship between canopy height derived from DAP and field-based NFI measures of woody AGB across four inventory periods. Over the environmentally heterogeneous area of Switzerland, our models have a comparable predictive performance (R2 = 0.54) to previous work predicting AGB based on ALS metrics. Pearson correlation coefficients between measured and predicted changes in woody AGB over time increased with shorter time gaps ( Numéro de notice : A2020-717 Affiliation des auteurs : non IGN Thématique : FORET/IMAGERIE Nature : Article DOI : 10.1016/j.jag.2020.102116 Date de publication en ligne : 15/04/2020 En ligne : https://doi.org/10.1016/j.jag.2020.102116 Format de la ressource électronique : url article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=96292

[Termes IGN] volume en boisRésumé : (auteur) Growing demand for wood products, combined with efforts to conserve natural forests, have supported a steady increase in the global extent of planted forests. Here, a two-phase sampling strategy for large-scale assessment of the total area and the total wood volume of fast-growing forest tree crops within agricultural land is presented. The first phase is performed using tessellation stratified sampling on high-resolution remotely sensed imagery and is sufficient for estimating the total area of plantations by means of a Monte Carlo integration estimator. The second phase is performed using stratified sampling of the plantations selected in the first phase and is aimed at estimating total wood volume by means of an approximation of the first-phase Horvitz-Thompson estimator. Vegetation indices from Sentinel-2 are exploited as freely available auxiliary information in a linear regression estimator to improve the design-based precision of the estimator based on the sole sample data. Estimators of the totals and of the design-based variances of total estimators are presented. A simulation study is developed in order to check the design-based performance of the two alternative estimators under several artificial distributions supposed for poplar plantations (random, clustered, spatially trended). An application in Northern Italy is also reported. The regression estimator turns out to be invariably better than that based on the sole sample information. Possible integrations of the proposed sampling scheme with conventional national forest inventories adopting tessellation stratified sampling in the first phase are discussed.

[Vedettes matières IGN] Inventaire forestierRésumé : (auteur) Ce document présente les éléments principaux de l’échantillonnage et les méthodes d’estimation mises en œuvre dans l’Inventaire Forestier National (IFN) depuis sa réforme en 2004, à l’origine de la « nouvelle méthode d’inventaire ». Il reconstitue le raisonnement logique permettant d’aboutir aux estimateurs statistiques implémentés depuis 2005 et représente ainsi un effort de formalisation conforme à la théorie des sondages. L'enquête IFN est très complexe car à la fois spatiale, temporelle, portant sur une population dynamique et ayant de très nombreux attributs à évaluer simultanément. Elle a donc déployé des méthodes d'échantillonnage et d'estimation spécifiques et originales, essentiellement basées sur un échantillonnage en deux phases et l'emploi poussé de la post-stratification.

[Vedettes matières IGN] Inventaire forestierRésumé : (éditeur) This book aims at presenting the estimation methods used in the first cycle of the National Forest Inventory in Romania. Romania is the twelfth largest country in Europe, and its forest vegetation area is larger than that of Austria and Switzerland together. Yet the last forest inventory in Romania was made in 1984 and based on forest management plans, not on specific sampling and measurements.
The expectations from the inventory were therefore very high and diverse. Like any other modern inventory, RO-NFI was designed to be a multi-purpose inventory which would deliver quantitative data to the ministry and forest administrations, but also to provide the data required for the periodical reporting such as the greenhouse gas reporting. While it started from scratch, the National Forest Inventory has integrated the most recent sampling methods used in countries with similar forest conditions, such as Germany, Austria and Switzerland. The book presents the sampling methods and conclude on the effects of the estimation method on the national-level growing stock, which brings relevant information for professionals from the field, but also for policy-desion makers interested in the use of national forest inventories for reporting on forest carbon emissions and storage.Note de contenu : Preface
