National research forests

Natural Resources Canada, through the Canadian Forest Service, maintains two research forests (Acadia and Petawawa) and one research station (Valcartier). These living laboratories have a long legacy of providing scientific data that inform researchers, scientists and industry about long-term trends to help address forestry issues now and in the future.

Research programs

With their combination of history, experimental sites and data, the Acadia and Petawawa research forests offer unique opportunities for both long- and short-term research. Current areas of research, and potential collaborative research opportunities, include:

  • enhanced forest inventories based on remote sensing
  • enhanced forest productivity through silvicultural treatments
  • biological evaluation of alternative harvesting treatments
  • forest health
  • forest vegetation management alternatives
  • forest diversity and natural succession
  • biodiversity
  • provenance trials using seed from various geographical locations
  • clonal studies, including somatic embryogensis
  • climate change adaptation
  • sustainable forest management
  • forestry best management practices
  • species at risk
  • spruce budworm research on endemic populations

The knowledge gained from research conducted at Acadia and Petawawa will continue to enhance socio-economic benefits for forest management practices around the world and aid in forest policy decision-making. NRCan is dedicated to addressing current forestry issues, while providing the opportunity, under secure conditions, to investigate anticipated forestry issues that have yet to arise.

Acadia Research Forest

The Acadia Research Forest (ARF) is located 20 km northeast of Fredericton, New Brunswick on Highway 10.

Established in 1933, the ARF continues to operate as one of the oldest and longest-running research forests in Canada. The ARF contains some of the oldest documented forest research studies in Canada, including seedling experiments established in 1923, which the ARF maintains to this day. These ongoing studies represent a wealth of knowledge and a scientific legacy that continues through various new and innovative forms of research.

Overseen by the Atlantic Forestry Centre, the ARF is dedicated to:

  • Facilitating ongoing forest research through long-term, secure research sites
  • Applying sustainable forest management principles and managing timber resources
  • Protecting wildlife habitats (aquatic and wetlands) and species at risk

The importance of the ARF as a secure place to conduct long-term research and as a demonstration, training, and educational facility has never been greater. Research forests play a valuable role in addressing the needs of Canada’s forest industry and contributing to the competitiveness of Canada’s forest sector. The knowledge gained from research conducted at the ARF continues to enhance forest management practices and aid in forest policy decision-making.


Since its creation, the ARF operates as an outdoor laboratory for forestry research, providing scientists with secure, long-term research sites. This mandate has been an integral part of the forest’s history, as the oldest research sites still maintained at the ARF date from before the forest was founded. Education and training have also been integral to the ARF from its very beginnings.

  • 1920s – Silviculture research starts on future site of the ARF with studies on stand development, forest ecology, response to thinning, partial harvesting methods, nursery practices, reforestation techniques, and site classification.
  • 1930s – Site developed through labour provided by Department of National Defence’s relief camps. Between 1938 and 1939, the ARF begins offering 9-week “Youth Training Short Courses in Forestry” to young farmers.
  • 1933 – The ARF begins inventory of the forest near Fredericton, New Brunswick.
  • 1940s – During the Second World War, the Department of National Defence used the ARF as an internment camp with work carried out by inmates.
  • 1950s – Silviculture research continues; tree improvement program formalized, which marked the beginning of many collaborative experiments done at the ARF; research into spruce budworm epidemic begins.
  • 1960s – Spruce budworm research continues at the ARF and timber sales begin. Annual production at the nursery reached 100,000 seedlings mid-decade; large-scale timber sales revenue began.
  • 1970s – The ARF increases its emphasis on hardwood management, including commercial thinning and other partial harvest treatments; spruce budworm research winds down as epidemic concludes.
  • 1980s – The ARF continues to be primary field research facility, while CFS nursery is relocated to the newly constructed Atlantic Forestry Centre, in Fredericton NB.
  • 1990s – The ARF continues to develop sustainable forest management and implements best management practices (BMPs).
  • 2000s – The ARF continues many studies, including Acadian alternative silviculture, white spruce genetic thinning as well as red and black spruce hybrid experiments. Some of these studies lead to the registration of some herbicide products currently registered today in Canada.
  • 2010s – In collaboration with its partners, the ARF establishes the University of New Brunswick’s Ecological Monitoring Tower and Canada’s National Geomagnetic Calibration Facility. In 2014, post-tropical storm Arthur caused a blowdown of natural stands and research plantations, leading to a series of salvage harvest operations in early 2015.

The ARF contains a number of genetic, provenance and tree improvement plantations, hundreds of research sites, and ecological reserves representing a variety of natural forest conditions common to the Acadian forest region. Research activities include studies on forest inventory, climate change, insect and disease life cycles and control, tree growth, timber harvest methods, tree improvement, biodiversity, species at risk, and endemic spruce budworm populations.

  • The Accuair® Wind Tunnel is a state-of-the-art facility used to measure how pesticides disperse when sprayed from an airplane under various flying conditions. Before 2003, the wind tunnel functioned as a portable research unit but has since been made a permanent fixture at the ARF. It is now owned, operated and managed by Forest Protection Limited.
  • LiDAR Technology Light Detection and Ranging (LiDAR) is changing how forest inventory is carried out. Leading Edge Geomatics, a Fredericton-based company, tests equipment and develops their LiDAR products at the ARF. As a result, LiDAR information has been acquired at different intensities over the past few years for the entire ARF, and is being used to highlight and promote the power of using LiDAR technology for forestry applications.
  • Ecological monitoring tower – This 31m tower, launched in 2013 and co-managed with the Atlantic Forestry Centre, provides an outdoor laboratory equipped with a full suite of meteorological equipment. The tower is capable of measuring carbon fluxes, water and energy exchange in the air and soil, temperature, humidity and atmospheric pressure.
  • Geomagnetic calibration facility – The latest addition to the ARF’s suite of high-tech installations is a geomagnetic calibration facility. Completed in 2016, this specialized facility is used to calibrate equipment that monitors, forecasts and reports on the earth’s magnetic field and on space weather, which can cause disturbances such as power outages and disruptions to GPS navigation systems.

Valcartier Forestry Research Station

The Valcartier Forestry Research Station (VFRS) is a natural site annexed to the Laurentian Forestry Centre located 35 kilometres north of Québec City.


Founded in 1934, the Valcartier Forestry Research Station (VFRS) is managed by NRCan through the Laurentian Forestry Centre and occupies an area of 68 hectares, divided between two sites. The first site, the VFRS administrative sector is part of the Valcartier Military Base and is 46 hectares. The second site, the Serge-Légaré Arboretum, is 22 hectares and was acquired by NRCan in 1987.

The VFRS’s development and contributions:

  • 1934 – VFRS opens as part of the Unemployment Relief program.
  • 1930s – 1940s – VRFS employees plant trees, cut wood, build roads, establish the headquarters facilities and oversee national inventory activities.
  • 1950s – 1960s – The VFRS expands its research areas to include forest ecology, fertilization, forest measurement, fire protection, entomology, pathology, silvicultural treatments, forest regeneration, and cutting methods.
  • 1970s – 1980s – Expanded research work in forest genetics through the establishment of plantations and the conducting of provenance trials. Beginning of forest management projects on Department of National Defence lands. Construction of three additional greenhouses to meet the requirements of researchers working in forest genetics, seedling physiology and forest regeneration.
  • 1990s – 2000s – Although several other research stations in Québec ended operations, the VFRS continues its activities because most of the research conducted there, including somatic embryogenesis research, contributes to the genetic improvement of forest trees used for the reforestation of Québec forests.
  • 2010s – New research areas: potential of trees to decontaminate soil; testing of quantities of biomass in genetically modified tree plantations; and effect of biomass harvesting on soil quality. Installation of a containment facility approved by the Canadian Food Inspection Agency and of a climate change simulation system.

The VFRS has 25 active experimental facilities. The three main research fields include forest genomics, climate change and forest biomass:

Forest genomics

  • The VFRS has several long-term facilities, including high genetic value coniferous plantations. The VFRS supports genetic improvement of trees by provenance tests, progeny tests and second generation genetic improvement clone banks.
  • Provenance tests combine seeds covering the entire distribution range of the species, including the United States of America and Europe.
  • The VFRS has containment areas approved by the Canadian Food Inspection Agency that are used exclusively for genomics.

Climate change

  • A unique facility in Quebec, the VFRS has a climate change simulation system.
  • Researchers use the simulator to study the effect of climate change on insects, such as the spruce budworm, or the phenology of the balsam fir or the black spruce.

Forest biomass

  • A work-in-progress, VFRS’ scientists seek to determine the effects of biomass collection on soil quality (see a virtual tour of an experimental site, best viewed in Google Chrome) and the impacts of spreading biomass heating ashes on the soil.
