Targets for each ecosystem were varied based on finer-scale ecological risk. 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. Ecosystems are at high risk where old growth covers less than 30% of the expected level of the historic distribution within a BEC subzone/variant. This layer was produced by the Old Growth Technical Advisory Panel and further details on the methodology and links to full datasets may be found on the Skeena Salmon Data Centre. 51.5145269897255 -138.0669023275954 60.40661152261951 -122.4261742063359
