This layer shows the remaining old forest with the largest trees in each ecosystem (BEC subzone/variant) in northwestern BC, as described by tree height and diameter. The layer shows the greater of the biggest remaining old forest up to 10% of the forested area or up to 30% of the naturally expected amount of old forest for each ecosystem, reflecting ecological variability in the natural historic distribution of old forest. In cases where big-treed ecosystems have less than 10% of the historic distribution of old growth, the biggest older mature forest was included to reach the target amount, if possible. This layer was produced by the Old Growth Technical Advisory Panel and further details on the methodology and links to full datasets can be found on the Skeena Salmon Data Centre.
