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 structure including: (i) metrics calculated directly from the lidar point cloud with heights normalized to heights above the ground surface (e.g., canopy cover, height), and (ii) modelled inventory attributes, derived using an area-based approach generated by using co-located ground plot and ALS data (e.g., volume, biomass).

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).

Canada's National Forest Inventory (NFI) sampling program is designed to support reporting on forests at the national scale. On the other hand, continuous maps of forest attributes are required to support strategic analyses of regional policy and management issues. We have therefore produced maps covering 4.03 × 106 km2 of inventoried forest area for the 2001 base year using standardised observations from the NFI photo plots (PP) as reference data. We used the k nearest neighbours (kNN) method with 26 geospatial data layers including MODIS spectral data and climatic and topographic variables to produce maps of 127 forest attributes at a 250 × 250 m resolution.
