Conference Theme

Soils-Forests Interactions in Changing Environments

The 13th North American Forest Soils Conference is being held jointly with the 9th International Symposium on Forest Soils in the UNESCO World Cultural Heritage Site of the Historic District of Old Québec in the spring of 2018. We cordially invite you to consider participating in this conference.

We invite presentations on research using field trials, laboratory investigations, long-term monitoring experiments and ecosystem modelling studies that address the conference theme and sub-themes. If possible, presentations should include a statement of the forest management implications of the work. The conference sub-themes are intended to encourage submissions with broad representation of the various soils-forests regions of North America and internationally.

Thematic Sessions

  1. The role of forests and forest soils in climate change adaptation and mitigation
    This session will examine forest C and nutrient cycling and soil C sequestration under a changing climate. Research focused on the response of soil processes on upland and wetland forests to climate change and best management practices to protect soil carbon stocks will be included in this session.
  2. Technological advances in forest soils research
    This session will examine how new emerging technologies have made a difference in the management of forests and forest soils. Advances in research methods from the molecular (soil microbiome, DNA extractions, qPCR) to the landscape (remote sensing, LIDAR, digital soil mapping) level will be included in this session.
  3. Management practices, land-use change and soil-forest productivity
    This session will examine the effects of forest management and changing land cover type on soil productivity and biodiversity. Research focusing on intensive biomass harvesting, land reclamation and evaluating site sensitivity to soil degradation will be included in this session.
  4. Societal change and forest soils: a balancing act
    This session will examine the challenge of balancing the changing expectations of society with scientific knowledge to form policies, regulations and practices for sustainable forest soil management. Changes in forest soil science research emphasis, such as development of soil health indicators and quantification of ecosystem services, will be highlighted. Communication and outreach strategies that translate research results into science policy that meet current and future needs will be included in this session.
  5. Fire effects on forest soils
    This session will examine fire effects on soil processes and the consequences of changing fire regimes on forest soils. Research evaluating how changes in soil processes due to fire impacts affects vegetation communities, carbon and nutrient cycling, and water quality will be included in this session.
  6. Forest soil monitoring networks and environmental change: successes and challenges
    This session will examine the design, implementation and results from national, regional and local forest soil monitoring programs. Soil resampling protocols, methodological issues and the significance of these networks in the monitoring of soil under large-scale environmental change will be included in this session.

The Quebec City region has a lot to offer in terms of ecological diversity. It is the meeting place of three geological formations (The Appalachian, the St-Lawrence Lowlands and the Laurentians), it is where the saltwater meets the fresh water in the St-Lawrence estuary; it is where the Northern hardwood biome meets the boreal forest. The one day field visit will take you through various ecosystems and the visit will highlight soil type and ecosystem management as well as forest research and will include a visit of the boreal forest of University Laval Montmorency Forest one of the largest teaching and research forests in the world.

The banquet will take place in the Séminaire de Québec in the old town, at a walking distance from Hôtel Château Laurier. The Séminaire (seminary) was founded in 1663, making it the oldest post-secondary institution in Canada. It gained university status and the power to award degrees by royal charter issued by Queen Victoria in 1852 to become Université Laval. The current building was built in the 1850s. 


Optional Post-conference Tour

The post-conference tour will take you to the Charlevoix region, recognized by UNESCO as a Biosphere Reserve and hosting the 2018 G-7 meeting. The landscape, extending from an elevation of 5 to 1,150 meters above sea level, includes a wide range of ecosystem and soil types ranging from the estuarine tidal flats to mountain tundra and providing spectacular landscapes. The tour will provide an opportunity to appreciate how the climate and the complex geological and geomorphological history of the region (including a large meteor crater, deposits from the Goldthwait sea, major landslides, etc. ) has shaped the ecosystems, the development of the land, and has defined the challenges that lie ahead for the sustainable development of this region in the face of climate change.

Day 1: We will be accompanied by Matthew G. Hatvany, Professor, Department of Geography, U. Laval. (

Day 2: We will be accompanied by Serge Payette, Professor, Department of Biology, U. Laval ( to visit the boreal and subarctic ecosystems of Les Grands-Jardins. Serge uses ecological and paleo-ecological studies, tree population ecology as well as dendroecology to better understand these ecosystems. We will hike through boreal and subarctic ecosystems and examine plants and soils typical of these environments, which are uncommon at this latitude.

Hôtel Château Laurier is ideally located in the heart of the city, on Parliament Hill, nestled between the Plains of Abraham, a vast urban park, the lively Grande Allée street and the old city.

This amazing sector is recognized as a UNESCO world heritage site since 1985 and is the birthplace of the French civilisation of North America. To this day, Québec is the only city where the fortification wall remains intact since the 17th century.
