Description:
This project, carried out on behalf of Tolko Industries Ltd. (Tolko), is the culmination of work begun in March, 2003 at the request of Riverside Forest Products Limited (RFP). Denny Maynard & Associates Ltd. (DMA) was retained to assess the extent and quality of existing terrain stability mapping (TSM) for the northern part of TFL 49, including the northern half of Block A and all of Block B, as well as the adjacent Forest Licences A18667 and A18689. As a result of this assessment, a field mapping program was carried out (Denny Maynard & Associates Ltd., 2005a) to upgrade the existing detailed TSM in the north half of TFL 49A (Quaterra Environmental Consulting Ltd., 1999). Concurrent with this upgrading project, preliminary photo-interpretive mapping was begun for detailed terrain stability mapping of Blocks B and C of TFL 49, an area that encompasses 65,653 ha at the northern end of the tree farm licence. A report on this preliminary mapping was submitted to RFP (Denny Maynard & Associates Ltd., 2005b). The aforementioned forest licences adjacent to the TFL were not included in this work. This present report discusses the methods and results of the completed terrain stability mapping of Blocks B and C of TFL 49. It consists of a 1:20,000-level analysis of the terrain landscape and an assessment of the potential effects of conventional forest harvesting on terrain stability. Field work for the project was carried out in June and July, 2005. Final interpretation of the aerial photographs and digital map production occurred between December, 2005 and July, 2006. The mapping has been submitted as both digital and hard copy (paper) products. Completion of the project in its entirety required an extension into the early part of fiscal 2006-07. The project was funded by the Forest Investment Account (Project Nos. FIA SOTFL49 4509002 and 4668002). Data and interpretations are presented at a level that are suitable for helping to plan forestry development, but are not usually detailed enough to substitute for site-specific, operational recommendations and decisions.
