    Update to Seral Stage and Patch Size Distribution Analyses for the North Coast Timber Supply Area

Series: Forest Investment Account (FIA) - Land Base Investment Program
An analysis of the forest cover information was conducted to determine the seral and patch distributions for Landscape Units within the North Coast Timber Supply Area. This analysis was carried out at two points in time: at the end of 2007, and then at the end of 2012, after aging the forest cover and including projected harvesting.
There are instances where seral stage imbalances exist on a proportional basis for licensees who have Forest Development Units that do not fully overlap with Landscape Units. These cases should be reviewed to address the imbalances and ensure that they do not affect other licensees. Information is provided on mid-seral and old seral constraints for Site Series Surrogates as defined in the Central and North Coast Order. In addition, analyses to support the implementation of objectives for important fisheries watersheds and for upland streams are also provided, identifying areas that should be reviewed in more depth. One of 31 important fisheries watersheds is identified for further analysis. Five of 527 upland watershed areas are identified as requiring further examination. These results do not reflect any additional forest management contstraints that will result from the March 27, 2009 amendment to the Central and North Coast Order. The effects of this amendment should be modeled and incorporated into this update as soon as possible. Patch size distribution results for the North Coast TSA are provided. This information should limit conflicts between licencees when proceeding with block development, and will inform both licencee and Ministry of Forests and Range staff when considering the potential for cumulative impacts on the forest landbase.
Information is also provided for the seral stage and patch size distribution results for licencee Forest Development Units within Landscape Units, and tables are provided for licencees to review their specific situations.
