Description

This layer is the authoritative source for locating Active Status Growth and Yield plots also known as Permanent Sample Plots (PSPs). These plots are protected and require an additional minimum windfirm buffer of 50m radius in the interior and 100m radius on the coast. These plots are generally 16m radius fixed area plots. Therefore, protected areas need to be a minimum of 66m radius around the plot centre in the interior and 116m radius on the coast. Best practices are to locate the plot centre on the ground as coordinate accuracy varies. The program now maintains partially damaged plots in order to provide critical data on how partially damaged plots grow over time. Therefore, salvage logging is NOT permitted within protected plots. Please contact Anya Reid (Anya.Reid@gov.bc.ca) with questions or updated coordinates for plots. NOTE: Accuracy of the coordinates are variable. Coordinates for plots with a more recent (since 2000) last measurement are generally quite accurate (3m). However, plots measured in the 1990's have a wide range of coordinate accuracy. In all cases, it is necessary to ground truth plot location before block layout. In this spatial layer, low accuracy coordinates are buffered 300m to ensure they do not get missed from development planning. This layer replaces the [Growth and Yield Samples – Active Status](https://catalogue.data.gov.bc.ca/dataset/0ca49478-5d0f-44e8-b6af-3fd6e387803c) layer with more accurate and current information from the Inventory Sample Management Consolidation (ISMC) database.
