Article
Full-text available
Understanding long‐term forest fire histories of boreal landscapes is instrumental for parameterizing climate‐fire interactions and the role of humans affecting natural fire regimes. The eastern sections of the European boreal zone currently lack a network of annually resolved and centuries‐long forest fire histories. To fill in this knowledge gap,...
Article
Full-text available
Dendrochronological reconstructions inform us about historical climate-fire-human interactions, providing a means to calibrate projections of future fire hazard. Most of these reconstructions, however, have been developed in landscapes with a considerable proportion of xeric sites that could potentially inflate our estimates of the historic levels...
Article
Full-text available
Understanding factors driving fire activity helps reveal the degree and geographical variability in the resilience of boreal vegetation to large scale climate forces. We studied the association between sea ice cover in the Baffin Bay and the Labrador Sea and observational records of forest fires in two Nordic countries (Norway and Sweden) over 1913...
Article
Full-text available
Bilberry spruce forests are the most widespread forest type in the European boreal zone. Limiting the clear-cuttings size leads to fragmentation of forest cover and the appearance of large areas of ecotone complexes, composed of forest (F), a transition from forest to the cut-over site under tree canopy (FE), a transition from forest to the cut-ove...
Article
Fire is a major disturbance agent in the boreal forest, affecting the structure, dynamics and biogeochemical cycles in this biome. In the Asian section of boreal forest, the records of long-term fire history are few that limits our understanding of factors forcing regional fire dynamics. We presented an annually-resolved 352-year (1666–2017) fire c...
Article
Full-text available
Fire remains one of the main natural disturbance factors in the European boreal zone and understanding climatic forcing on fire activity is important for projecting effects of climate change on ecosystem services in this region. We analyzed records of annually burned areas in 16 administrative regions of the European boreal zone (countries or admin...

We evaluated the skills of different palaeofire reconstruction techniques to reconstruct the fire history of a boreal landscape (Russian Karelia) affected by surface fires. The analysis of dated lacustrine sediments from two nearby lakes was compared with independent dendrochronological dating of fire scars, methods which have rarely been used in c...
Article
Spatially explicit reconstructions of fire activity in European boreal forest are rare, which limits our understanding of factors driving vegetation dynamics in this part of the boreal domain. We have developed a spatially explicit dendrochronological reconstruction of a fire regime in a 25 × 50 km 2 area within boreal biome located within the Kale...
Article
Full-text available
Abstract We explored whether, and to what extent, variable retention (VR) forestry has been applied in European boreal forests in northwestern Russia. Our survey revealed VR since 1910. Between 1910 and the 1960s, the statistics showing how much was retained are largely missing. However, for example, in the 1950s, on a large scale in the Republic o...

Article
Because large-scope continuous clear-cutting was widely practiced in Northwest Russia in the second half of the 20th century, secondary forest communities now prevail in Karelia and adjacent regions. The species and habitat diversity of such communities is much higher than that of climax communities. The main problem in the attempts for their syste...
Article
Full-text available
The concept of the "phytogenic field" proposed by Uranov is in agreement with the concept of the field as a source of connections in the system. Referring to space modified by a plant, the phytogenic field does not have distinct boundaries and is fundamentally infinite. The complex structure of the phytogenic field is determined by a multiplicity o...

Project
The goal of my 3-year phD project (2016-2019) is to analyse and describe the fire history of boreal forests during Holocene in Russia (3 areas: Komi Republic, Karelia and Lake Baïkal region). This analysis will be carried out through the study of charcoal from lake or peat cores. The history of the vegetation and the composition of the forest in these zones, as well as the different types of successions that will be brought to light, thanks to palynology. Then the pollen data and the use of independent climate data will allow the reconstruction of the past climate for these regions. This project is related to the PREREAL project (http://www.prereal.org/index.htm) which aims to identify climatic drivers controlling boreal fire activity and its predictability and to translate these into impacts on ecosystem services and metrics of socio-economic performance.
