This dataset is associated with the article authored by Marine Pacé, David Paré, Nicole Fenton and Yves Bergeron entitled "Effect of lichen, Sphagnum spp. and feather moss leachates on jack pine and black spruce growth ". It includes growth surveys of jack pine and black spruce in greenhouse at different stages of development (0-6 month-old and 2 year-old seedlings). Seedlings were subjected to different types of leachates: jack pine was subjected to control (bare soil), feather moss and lichen leachates; black spruce was subjected to control (bare soil), feather moss and Sphagnum spp.

This database contains the data set described in Andrieux B. et al. (in preparation) about carbon stocks in Quebec's spruce feathermoss forests. Carbon density in different reservoirs of the ecosystem is available at the plot scale (n = 72): living aboveground biomass, coarse woody debris, organic soil horizon, mineral soil (top 15 cm), mineral soil (15-35 cm) and illuvial (B) horizon (top 15 cm). Ancillary biophysical data includes geographic locations, topographic surveys, composition of the moss mat, time since fire, and soil properties (carbon content, bulk density, forest floor depth, pH, texture and amorphous metals).

This database contains the data set described in Andrieux B. et al. (in preparation) about soil organic carbon bioreactivity in Quebec's spruce feathermoss forests. The soil carbon bioreactivity has been evaluated with long-term lab incubations. Carbon density in different soil functional reservoirs is available at the plot scale (n = 72): total C stock in the O layer (FH horizon), total C stock in the mineral soil (0 to 35 cm), total bioreactive C stock, total acid-insoluble C stock.

To slow the spread of the Brown spruce longhorn beetle to new areas, the Canadian Food Inspection Agency (CFIA) uses measures to control the movement of potentially infested materials. Slowing the spread of the Brown spruce longhorn beetle will protect Canada's environment and forest resources. It also helps keep international markets open to the forest industry and nurseries in non-regulated parts of Ontario and Quebec and in the rest of Canada.

Browse surveys occur yearly in July-August and are conducted by park staff. Each plot is composed of nine circular subplots (2-m radius) in a 3 x 3 grid, spaced at 15 m intervals. The number of seedlings (5 – 30 cm) and saplings (30 – 200 cm) of each tree species are counted. Seedling recruitment is correlated with herbivore abundance and provides an efficient method to assess browse pressure in forest ecosystems.

We measured the foliage area, weight and number of buds on young and mature balsam fir and white spruce trees. With these measurements total amounts of foliage per tree and per unit area of forest land can be calculated. These estimates can be used to determine the absolute numbers of insects feeding on these trees, numbers that are important in understanding patterns and fluctuations of population abundance. We also discovered that spruce budworm larvae occur preferentially in buds arranged in clusters.

This dataset is associated with the article authored by Jacques Régnière, Lisa Venier and Dan Welsh entitled "Avian predation in a declining outbreak population of the spruce budworm, Choristoneura fumiferana (Lepidoptera: Tortricidae)" which will be published in the "Insects" scientific journal. The impact of avian predation on a declining population of the spruce budworm, Choristoneura fumifereana (Clem. ), was measured using single-tree exclosure cages in a mature stand of balsam fir, Abies balsamea (L.), and white spruce, Picea glauca (Moench.) Voss.
