Forest Lidar Dendrometric Map for Quebec Planning Units

A 2026 vector map product provides fine-scale dendrometric characteristics for forest planning in Quebec. It includes predicted variables such as usable volume per hectare by species, basal area, and number of stems per hectare. The data is complementary to other forest inventories and covers territories with LiDAR acquisition in specific bioclimatic domains.

Use Cases

• Model usable volume per hectare by species and diameter groups for harvest planning.
• Analyze basal area and number of stems per hectare for specific species groups to assess forest density.
• Compare volume per hectare distributed by product across different species groups for economic valuation.
• Integrate average usable volume per rod and average diameter data into growth and yield models.

Strengths

• Provides data at a finer geometric scale than the standard ecoforest map.
• Includes distinct 'usable' volume variables excluding specific woody material.
• Covers multiple bioclimatic domains: fir to yellow birch, fir to white birch, and spruce moss.

Limitations

• Coverage is not complete and is limited to territories with LiDAR acquisition.
• Data availability and evolution depend on future LiDAR acquisition campaigns.
• Requires understanding of the methodological differences between 'usable' and other volume variables.
