The data used in this compilation come from the Canadian Gravity Database (CGDB), which is managed by the Canadian Geodetic Survey (CGS), Surveyor General Branch. CGDB includes more than 755 000 observations, including some 232 000 observations on land. The distribution of the land data...

Forest 95th Percentile Elevation(Ht) 201595th percentile of first returns height (m). Products relating the structure of Canada's forested ecosystems have been generated and made openly accessible. The shared products are based upon peer-reviewed science and relate aspects of forest structure...

Forest Total Aboveground Biomass 2015Total aboveground biomass. Individual tree total aboveground biomass is calculated using species-specific equations. In the measured ground plots, aboveground biomass per hectare is calculated by summing the values of all trees within a plot and dividing by...

Forest Lorey's Height 2015Lorey's mean height. Average height of trees weighted by their basal area (m). Products relating the structure of Canada's forested ecosystems have been generated and made openly accessible. The shared products are based upon peer-reviewed science and relate aspects of...

Wildfire Year/dNBR/Mask 1985-2015Wildfire change magnitude 85-15. Spectral change magnitude for wildfires that occurred from 1985 and 2015. The wildfire change magnitude included in this product is expressed via differenced Normalized Burn Ratio (dNBR), computed as the variation between the...

Forest Basal Area 2015Cross-sectional area of tree stems at breast height. The sum of the cross-sectional area (i.e. basal area) of each tree in square metres in a plot, divided by the area of the plot (ha) (units = m2ha). Products relating the structure of Canada's forested ecosystems have been...

Forest Percentage Above 2m 2015Percentage of first returns above 2 m (%). Represents canopy cover. Products relating the structure of Canada's forested ecosystems have been generated and made openly accessible. The shared products are based upon peer-reviewed science and relate aspects of forest...

Forest Elevation(Ht) Mean 2015Mean height of lidar first returns (m). Represents the mean canopy height. Products relating the structure of Canada's forested ecosystems have been generated and made openly accessible. The shared products are based upon peer-reviewed science and relate aspects of...

Forest Elevation(Ht) Stddev 2015Standard deviation of height of lidar first returns (m). Represents the variability in canopy heights. Products relating the structure of Canada's forested ecosystems have been generated and made openly accessible. The shared products are based upon peer-reviewed...

Forest Gross Stem Volume 2015Gross stem volume. Individual tree gross volumes are calculated using species-specific allometric equations. In the measured ground plots, gross total volume per hectare is calculated by summing the gross total volume of all trees and dividing by the area of the plot...

Forest Percent Above Mean 2015Percentage of first returns above the mean height (%). Represents the canopy cover above mean canopy height. Products relating the structure of Canada's forested ecosystems have been generated and made openly accessible. The shared products are based upon...

High-resolution binary wetland map for Canada (2001-2016). Wetland map for the forested ecosystems of Canada focused on current conditions. The binary wetland data included in this product is national in scope (entirety of forested ecosystem) and represents the wall to wall characterization...

High resolution forest change for Canada (Binary Change/No-change) 1985-2011 The forest change data included in this product is national in scope (entire forested ecosystem) and represents the first wall-to-wall characterization of wildfire and harvest in Canada at a spatial resolution...

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,...

This project aims at linking biotic and climatic stresses and tree mortality in the boreal forest.

This dataset is associated with the article by Marine Pacé, Nicole J. Fenton, David Paré and Yves Bergeron entitled "Differential effects of feather and Sphagnum spp. mosses on black spruce germination and growth". It includes data of black spruce germination (greenhouse), seedling growth (0 to 6...

In the early 1980’s, thousands of trees were destructively sampled across Canada by the Canadian Forest Service (CFS) as part of the ENergy from the FORest research (ENFOR) program with the objective to produce regional biomass equations for the most common tree species. The sampling was...
