[Vedettes matières IGN] Inventaire forestierRésumé : (auteur) Over the past decades it has been shown that remotely sensed auxiliary data have a potential to increase the precision of key estimators in sample-based forest surveys. This thesis was motivated by the increasing availability of remotely sensed data, and the objectives were to investigate how this type of auxiliary data can be used for improving both the design and the estimators in sample-based surveys. Two different modes of inference were studied: model-based inference and design-based inference. Empirical data for the studies were acquired from a boreal forest area in the Kuortane region of western Finland. The data comprised a combination of auxiliary information derived from airborne LiDAR and Landsat data, and field sample plot data collected using a modification of the 10th Finnish National Forest Inventory. The studied forest attribute was growing stock volume.
The results of this thesis are important for the development of forest inventories to meet the requirements which stem from an increasing number of international commitments and agreements related to forests.Numéro de notice : 14978 Affiliation des auteurs : non IGN Thématique : FORET Nature : Thèse étrangère Note de thèse : PhD : Forest sciences : University of Helsinki : 2015 En ligne : Over the past decades it has been shown that remotely sensed auxiliary data have [...] Format de la ressource électronique : URL Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=78366 Deadwood and tree microhabitat dynamics in unharvested temperate mountain mixed forests: A life-cycle approach to biodiversity monitoring / Laurent Larrieu in Forest ecology and management, vol 334 ([15/12/2014])

[Vedettes matières IGN] Ecologie forestièreRésumé : (auteur) In forest ecosystems, conservation is often considered in the absence of any long-term dynamic perspective, yet dynamic processes extend over hundreds of years. Saproxylic taxa represent about 25% of the species diversity in temperate and boreal forests and they depend on both spatial and temporal continuity in the availability of deadwood and certain tree microhabitats. Our study focused on the dynamics of deadwood and tree microhabitats throughout the silvigenetic cycle in 32 unharvested European mountain mixed forests. Our dataset contained 178 plots classified into one of five forest development phases (regeneration, establishing, growing, culmination and disintegration). We analyzed how the amount and quality of deadwood and microhabitats varied according to the five phases. Contrary to expectations, deadwood and tree microhabitat availability remained more or less stable throughout the silvigenetic cycle, both in quantity and diversity. Furthermore, whether the forests were dominated by broadleaves or conifers, there were no significant differences in terms of deadwood or tree microhabitat dynamics. Pioneer (Betula spp., Salix spp.) and post-pioneer species (Fraxinus exelsior, Sorbus spp., Prunus avium) played an important role throughout the silvigenetic cycle by providing a diversity of deadwood when deadwood from the dominant species (i.e. Abies alba, Fagus sylvatica, Picea abies) was scarce. Understanding the dynamics of deadwood and tree microhabitats may help us provide a model for forest managers who intend to emulate natural forest dynamics and will also improve our understanding of the relationship between forest dynamics and biodiversity conservation.

[Termes IGN] zone sinistréeRésumé : (Auteur) Context : In the Mediterranean area, different post-fire management strategies are used for coppices of resprouting species to promote a more regular forest structure, enhance plant growth, and reduce fire risk. However, the effects of these management treatments on forest-associated fauna are unknown, which in turn could be limiting their beneficial effects.
Aims : The aim of this work was to determine whether forest management of a recently burned area dominated by a vigorous resprouting tree species (Arbutus unedo L.) affects ant communities.
Methods : Ant communities, sampled using pitfall traps, were examined from unmanaged and selective thinning coppices of A. unedo. Ants are here used as bioindicators of ecosystem health and surrogates for other animal groups.
Results : Very limited effects of these post-fire management strategies on the structure and composition of ant communities were found. The lack of effects could be due to the reported small changes in physical conditions among treatments; or either, the most sensitive ant species to these post-fire management treatments might be the same ones affected by fire and, consequently, the ant species that would potentially be affected most were no longer in the study area.
Conclusion : The lack of any significant effects caused by these post-fire management practices on the associated fauna of A. unedo coppices points out the suitability of these treatments in these circumstances.Numéro de notice : A2014-580 Affiliation des auteurs : non IGN Thématique : FORET Nature : Article DOI : 10.1007/s13595-014-0381-5 Date de publication en ligne : 05/06/2014 En ligne : https://doi.org/10.1007/s13595-014-0381-5 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=74770

[Termes IGN] surveillance forestièreRésumé : (auteur) In this review paper, we present geographical, ecological and historical aspects of Southeast Asia from the perspective of forest degradation monitoring and critically discuss available approaches for large area forest degradation monitoring with satellite remote sensing data at high to medium spatial resolution (5–30 m). Several authors have achieved promising results in geographically limited areas within Southeast Asia using automated detection algorithms. However, the application of automated methods to large area assessments remains a major challenge. To-date, nearly all large area assessments of forest degradation in the region have included a strong visual interpretation component. We conclude that due to the variety of forest types and forest disturbance levels, as well as the variable image acquisition conditions in Southeast Asia, it is unlikely that forest degradation monitoring can be conducted throughout the region using a single automated approach with currently available remote sensing data. The provision of regionally consistent information on forest degradation from satellite remote sensing data remains therefore challenging. However, the expected increase in observation frequency in the near future (due to Landsat 8 and Sentinel-2 satellites) may lead to the desired improvement in data availability and enable consistent and robust regional forest degradation monitoring in Southeast Asia.

[Termes IGN] télémétrie laser terrestreRésumé : (Auteur) Detailed information about timber assortments and diameter distributions is required in forest management. Forest owners can make better decisions concerning the timing of timber sales and forest companies can utilize more detailed information to optimize their wood supply chain from forest to factory. The objective here was to compare the accuracies of high-density laser scanning techniques for the estimation of tree-level diameter distribution and timber assortments. We also introduce a method that utilizes a combination of airborne and terrestrial laser scanning in timber assortment estimation. The study was conducted in Evo, Finland. Harvester measurements were used as a reference for 144 trees within a single clear-cut stand. The results showed that accurate tree-level timber assortments and diameter distributions can be obtained, using terrestrial laser scanning (TLS) or a combination of TLS and airborne laser scanning (ALS). Saw log volumes were estimated with higher accuracy than pulpwood volumes. The saw log volumes were estimated with relative root-mean-squared errors of 17.5% and 16.8% with TLS and a combination of TLS and ALS, respectively. The respective accuracies for pulpwood were 60.1% and 59.3%. The differences in the bucking method used also caused some large errors. In addition, tree quality factors highly affected the bucking accuracy, especially with pulpwood volume.
