Restoration of riparian forests is one of the key management challenges we face in coastal BC. We have large areas of streams and riparian forests that were logged prior to the Forest Practices Code which require restoration to once again serve as effective salmon habitat. However, we are still in the process of determining the best methods both for restoration and monitoring its effectiveness. Further, often restoration projects are done on an ad hoc basis with no documentation of pre- or post-treatment effects, or as a one-time effort. The Kennedy Lake Restoration project is notable exception as it is a long-term restoration project so an excellent candidate to contribute to resolving these questions. Ideally we would document improvements created by restoration practices through comparisons with original forest conditions and forests with no restoration. Often baseline conditions prior to restoration are unknown. However, with the historical air photo record and early forest cover maps, it is possible reconstruct the pre-harvest forest composition. One of the key differences between old-growth and second-growth forests is structure and structural diversity, both vertically (range of tree/snags/coarse woody size and species) and horizontally (number of gaps and canopy complexity). Second-growth forests have very simplified structure compared to old-growth forests. The purpose of this project is to reconstruct pre-harvest forest conditions using historical inventory information for the riparian area of Lost Shoe Creek watershed. The original old-growth forest composition in turn can be used as baseline information for the ongoing restoration project.
