Article
Full-text available
There is a pressing need for a better understanding of changing forest fire regimes worldwide, especially to separate the relative effects of potential drivers that control burned areas. Here we present a meta-analysis of the impacts of climate fluctuation and Euro-Canadian settlement on burned areas from 1850 to 1990 in a large zone (> 100,000 km2...
Article
Increase in forest disturbance due to land use as well as climate change has led to an expansion of young forests worldwide, which drives global carbon dynamics and timber allocation. This study presents a method that combines a single airborne LiDAR acquisition and time since harvest maps to model height growth of post-logged black spruce-dominate...

Increase in forest disturbance due to land use as well as climate change has led to an expansion of young forests worldwide, which affects global carbon dynamics and forest management. In this study, we present a novel method that combines a single airborne LiDAR acquisition and historical harvesting maps to model height growth of post-logged black...
Article
Despite global biodiversity losses, trends at local and regional scales are context dependent. Recent studies have been criticized for lacking baselines preceding human impacts, and few such studies have addressed the landscape scale. Our aim was to quantify temporal trends in landscape‐scale tree diversity during an unambiguous period of massively...
Article
Full-text available
Forest fires are a key driver of boreal landscape dynamics and are expected to increase with climate change in the coming decades. A profound understanding of the effects of fire upon boreal forest dynamics is thus critically needed for our ability to manage these ecosystems and conserve their services. In the present study, we investigate the long...
Article
Full-text available
Human activities have changed forest composition of northeastern North America since European settlement by increasing the importance of pioneer shade-intolerant species, at the expense of shade-tolerant and long-lived species. This study used tree taxa lists from land survey archives (1842–1935) to document the pre-settlement forest composition in...

1. A better understanding of how disturbance impacts tree diversity at different scales is essential for our ability to conserve and manage forest ecosystems in the context of global changes. Here we test the impacts of land‐use related disturbances on tree diversity since the 19th century across a broad region (>150,000 km2) of northern temperate...
Article
Full-text available
How has European settlement of Eastern North America modified tree species assemblages?. The northern temperate forests of the Lower St. Lawrence region (Québec, Canada). Changes in relative prevalence of tree taxa were reconstructed with early land survey records (1821‐1900) and modern forest inventories (1980‐2010). Forest composition reconstruct...
Article
Full-text available
Predicting future ecosystem dynamics depends critically on an improved understanding of how disturbances and climate change have driven long-term ecological changes in the past. Here we assembled a dataset of >100,000 tree species lists from the 19th century across a broad region (>130,000km²) in temperate eastern Canada, as well as recent forest i...

L’aménagement écosystémique vise à diminuer les écarts entre forêts aménagées et naturelles, et doit s’appuyer sur des états de référence représentant les caractéristiques des forêts naturelles. Nous proposons d’utiliser la principale source d’information sur la composition de la forêt préindustrielle du sud du Québec, les archives d’arpentage, pou...
Article

ContextKnowledge of how environmental gradients generate changes in community composition across forest landscapes (β-diversity) represents a critical issue in the era of global change, which exerts especially powerful impacts by shifting disturbance regimes. Objectives We analyzed the response of tree communities to increased disturbance rates tha...
Article
Eastern white cedar (Thuja occidentalis L.) has been identified as a target tree species for ecological restoration in northeastern North America. Insight into long-term population dynamics since preindustrial times is key to guiding restoration efforts. In this study, we used a large set of early land survey data to assess the status of eastern wh...
Thesis
Full-text available
Les changements globaux modifient les écosystèmes forestiers à la fois de manière directe par l'usage des sols et l'exploitation des ressources forestières, et de manière indirecte avec les changements climatiques. La connaissance des dynamiques historiques des paysages forestiers est donc essentielle pour la conservation des écosystèmes et pour mi...
Article
Full-text available
Land use changes that are linked to European settlement of North America have transformed northeastern temperate forest landscapes. Many studies report a regional increase of young early-successional forests due to high disturbance rates since the preindustrial era (fire, land clearing, and clear-cuts). In this study, we document specific compositi...

What were the pre-industrial forest landscape composition patterns? Which factors had structured the pre-industrial landscape patterns? How have pre-industrial landscape patterns and post-industrial disturbances controlled composition changes? An area of 4175 km2 at the temperate–boreal forest interface of southwest Quebec, Canada. Reconstruction o...

Project
In this project we present a novel method that combines a single airborne LiDAR acquisition and historical forestry maps to model the height growth, density, and wood volume of boreal forest landscapes. The goal of this project is to provide to forest managers a tool to accurately evaluate wood supply and forest growth across large remote areas affected by fires and logging.
