Landscape-level planning in TFL 45 requires identification of sensitive sites and hydroriparian features for designing reserve networks. For sensitive sites analysis, International Forest Products (IFP) is adopting a similar approach to that used for a recently completed Interim Watershed Plan in the Clayoquot. Following recommendations from the Clayoquot Scientific Panel, criteria were developed for defining sensitive soils and unstable terrain which were applied to landscape-level inventory data. These formed the core of reserve networks. Hydroriparian planning in TFL 45 will assess the application of the Hydroriparian Planning Guide (HPG) in designing related reserve networks. This project is intended to provide core data to support that analysis. This follows the comprehensive testing of the HPG in three small coastal watersheds completed in 2003 (Warttig and Landers 2003). Existing resource information for TFL 45 (TRIM, TEM, terrain stability, stream classification) can be used in a GIS analysis for deriving preliminary spatial data on sensitive sites and hydroriparian ecosystems. Not all features used for identifying these areas are comprehensively covered in the existing inventory data. Where appropriate, these inventories can be revisited through a focused photo interpretation exercise, and enhanced to better reflect key site features. The objectives of this project are to: ? Identify opportunities for enhancing the TEM database to better reflect key site features used in identifying sensitive sites and hydroriparian ecosystems. ? Based on the previous, review original typed airphotos (TEM polygons) and delineate additional polygons to enhance the database for deriving candidate reserve areas. ? Based on analysis of available GIS databases, generate spatial themes for identifying sensitive sites and relevant hydroriparian features.
