| Abstract/Description or Keywords | In 1991 the Forest Resources Commission recommended a review of the provincial resource inventory process in its report The Future of our Forests. The result of that was a re-design of the inventory which resulted in the Vegetation Resources Inventory (VRI). The VRI is a photo-based, two-phased vegetation inventory design consisting of: Phase I: Photo Interpretation Phase II: Ground Sampling Within the ground sampling phase, Net Volume Adjustment Factor (NVAF) sampling is a mandatory component that is integral in the calculation of inventory adjustment factors. Vegetation Resources Inventories are typically funded by government. There is no re-inventory cycle per se and the decision of conducting a VRI is based on a number of factors including age of the inventory, known problems of the inventory, recent catastrophic events (such as mountain pine beetle) and other emerging issues that require a new inventory. Updating of the inventory due to changes in the forest such as harvesting, fire and other catastrophic events are done through electronic data submissions from licensees and as well through a combination of mapping from satellite imagery, aerial photography and Global Positioning System mapping. The Inventory is updated continuously. The VRI is housed on the Land and Resource Data Warehouse (LRDW) http://geobc.gov.bc.ca/ where the data can be viewed and downloaded. |
