Titre : Forest attribute maps: a support for small area estimation of forest disturbances Type de document : Article/Communication Auteurs : Cédric Vega , Auteur ; Ankit Sagar , Auteur ; Olivier Bouriaud , Auteur ; Jean-Pierre Renaud , Auteur Année de publication : 2025 Article en page(s) : 23 p. Langues : Anglais (eng) Descripteur : [Termes IGN] forêt [Termes IGN] Inventaire Forestier National (organisme France) Résumé : Key Message Forest attribute maps generated using national forest inventory and remote sensing data can be used to quantify forest attributes (i.e., growing stock volume, basal area) affected by disturbance events (like bark-beetle induced damage) through small area estimation techniques. Our results showed that mature stands were more sensitive to bark-beetle infestation than younger ones. Context: Recurrent drought episodes in Europe weakened trees and promoted biotic disturbances such as bark-beetle outbreaks, heavily affecting spruce (Picea abies (L.) H. Karst.) and fir stands (Abies alba Mill.). While remote sensing data make it possible to assess and monitor the spatial extent of outbreaks, the assessment of the actual impact on forest attributes is still lacking. Aims: We propose a small area estimation approach to assess the amount of forest attributes impacted in outbreak areas during the period 2021–2022 using forest attribute maps. Methods: We produced forest attribute maps using National Forest Inventory (NFI) plots, and auxiliary data from Light Detection and Ranging (LiDAR) and Sentinel-2, acquired in 2021. The maps were generated using a general k-nearest neighbour model for all forest species (general model) and a model specific to spruce and fir only (specific model). Small estimation domains, defined as bark-beetle outbreak areas, were obtained from an independent source using time series of Sentinel-2 data (2018–2022). Small area estimations were generated using bootstrapped model-predictions with reliability assessment. Results: In total, 1137 ha of forest area was affected by bark-beetle outbreaks during 2021–2022, corresponding to 494,000 m3 (general model) and 505,000 m3 (specific model) of growing stock volume, respectively. The associated errors were 2.2% for the general model and 2.6% for the specific model. In the specific model, the estimated mean growing stock volume in outbreak areas for 2021 and 2022 was 441.5 m3 ha⁻1, which was 64.5 m3 ha⁻1 higher than the estimated mean volume of spruce and fir for the whole area (377 m3 ha⁻1). This suggests that mature stands were more sensitive to infestation. Conclusion: Regular updates to forest attribute maps, possibly every third year using photogrammetric methods, could improve monitoring of forest attributes impacted by disturbances such as drought and bark-beetle outbreaks and contribute to forest decision making and planning.

Evenness mediates the global relationship between forest productivity and richness / Iris Hordijk in Journal of ecology, vol inconnu (2023)  

Public [article]  inJournal of ecology > vol inconnu (2023) Titre : Evenness mediates the global relationship between forest productivity and richness Type de document : Article/Communication Auteurs : Iris Hordijk, Auteur ; Daniel S. Maynard, Auteur ; et al., Auteur ; Olivier Bouriaud , Auteur Année de publication : 2023 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] forêt [Termes IGN] futaie irrégulière [Termes IGN] futaie régulière [Termes IGN] productivité biologique [Termes IGN] richesse floristique [Vedettes matières IGN] Foresterie Résumé : (auteur) 1. Biodiversity is an important component of natural ecosystems, with higher species richness often correlating with an increase in ecosystem productivity. Yet, this relationship varies substantially across environments, typically becoming less pronounced at high levels of species richness. However, species richness alone cannot reflect all important properties of a community, including community evenness, which may mediate the relationship between biodiversity and productivity. If the evenness of a community correlates negatively with richness across forests globally, then a greater number of species may not always increase overall diversity and productivity of the system. Theoretical work and local empirical studies have shown that the effect of evenness on ecosystem functioning may be especially strong at high richness levels, yet the consistency of this remains untested at a global scale. 2. Here, we used a dataset of forests from across the globe, which includes composition, biomass accumulation and net primary productivity, to explore whether productivity correlates with community evenness and richness in a way that evenness appears to buffer the effect of richness. Specifically, we evaluated whether low levels of evenness in speciose communities correlate with the attenuation of the richness–productivity relationship. 3. We found that tree species richness and evenness are negatively correlated across forests globally, with highly speciose forests typically comprising a few dominant and many rare species. Furthermore, we found that the correlation between diversity and productivity changes with evenness: at low richness, uneven communities are more productive, while at high richness, even communities are more productive. 4. Synthesis. Collectively, these results demonstrate that evenness is an integral component of the relationship between biodiversity and productivity, and that the attenuating effect of richness on forest productivity might be partly explained by low evenness in speciose communities. Productivity generally increases with species richness, until reduced evenness limits the overall increases in community diversity. Our research suggests that evenness is a fundamental component of biodiversity–ecosystem function relationships, and is of critical importance for guiding conservation and sustainable ecosystem management decisions.

The FunDivEurope exploratory platform allowed us to analyse this modulating effect in a medium-term time span, after an abrupt rise to a new stable level of the average summer temperature of ca 2°C, in Mediterranean forests in central Italy. This paper aims to answer the following questions: 1) did increasing temperature and drought events affect the growth of thermophilous deciduous forests? 2) Was this effect buffered in mixed stands compared to monocultures? 3) Did co-occurring tree species with different ecological characteristics, from more mesophilous to more xerophilous, have different responses? In 2012 and 2017, wood cores were collected from 659 trees in 36 plots representative of thermophilous deciduous forests. The selected tree species were Castanea sativa, Ostrya carpinifolia, Quercus cerris, Quercus ilex and Quercus petraea. In the sampling plots, they were present in pure stands and mixtures from two to four species. After measuring annual rings on cores, chronologies of basal area increment were built, and inventory data were used to estimate tree growth. Results showed a strong reduction of growth, lasting at least 18 years, after the temperature rise. Tree diversity significantly reduced the growth drop after the sudden and stable rise in summer average temperature. Tree mixture effect on growth stability appeared to be dependent on the tree species present in the mixture. Temperature rise and associated drought events, even without changes in rainfall, are one of the main challenges that European forests will face in the current scenarios of climate change. Tree diversity can buffer the effects of climate change over periods of at least 15 years and should be considered in forest management plans.
