FRI: Gross merchantable volume - hardwood

Gross merchantable volume - hardwood (GMVHWD) is an expression of merchantable stem hardwood volume (m3) on a per-hectare basis. Available here as a raster (GeoTIF) with a 20 m pixel resolution.

Download: Here The Saskatchewan Ministry of Environment, Forest Service Branch, has developed a forest resource inventory (FRI) which meets a variety of strategic and operational planning information needs for the boreal plains. Such needs include information on the general land cover, terrain, and growing stock (height, diameter, basal area, timber volume and stem density) within the provincial forest and adjacent forest fringe. This inventory provides spatially explicit information as 10 m or 20 m raster grids and as vectors polygons for relatively homogeneous forest stands or naturally non-forested areas with a 0.5 ha minimum area and a 2.0 ha median area.  Gross merchantable volume per hectare - hardwood (GMVHWD) is an expression of merchantable hardwood stem volume (m3) on a per-hectare basis. Calculations are made assuming a cut-to-length scenario, and including all stem wood from a 30 cm stump height to an 8 cm top diameter (inside bark), with a minimum bole length of 5.1 m and a minimum log length of 2.7 m for hardwood. GMVHWD is available here as a color-mapped 16-bit unsigned integer raster grid in GeoTIFF format with a 20 m pixel resolution. An ArcGIS Pro layer file (*.lyrx) is supplied for viewing GMVHWD data in the following 50 m3/ha categories. Domain: [NULL, 0…1000].
