A hallmark of old forests is that they contain old trees, but so much more is important about them. These forests provide ecologically valuable or critical habitats for animal and plant species as well as unique conditions and processes that are important for the conservation of biodiversity. Functional old forests deliver ecosystem services valued by people, including food, water, fuel, medicines, timber, recreation and tourism opportunities. Old forests provide cultural and spiritual values important to First Nations.Provincial policy for managing old forest has been based on the concept that the further from the natural distribution of old forest the higher the risk to biodiversity and ecological health. In the RSEA context, risk also relates to the ability of First Nations to exercise treaty rights on the landscape. Note that the RSEA Old Forest assessment reports on current condition based only on the amount of forest, not at the condition of forested ecosystems. The RSEA Old Forest Assessment applied two age thresholds (> 140 years and > 250 years) to assess the amount and distribution of all old forests. For the purpose of implementation and this RSEA assessment, old forest and contiguous old forest can be considered everything that is 140 years and older, that is contiguous, defined as touching or adjacent polygons.Data Properties<TABLE><TBODY><TR><TD>Attributes / Column Name</TD><TD>Field Alias</TD><TD>Data Type</TD><TD>Data Precision</TD><TD>Comments</TD></TR><TR><TD>OBJECTID</TD><TD>Object ID</TD><TD>Object ID</TD><TD></TD><TD>Unique row number auto generated by database</TD></TR><TR><TD>SHAPE</TD><TD>Shape</TD><TD>Geometry (Polygon)</TD><TD></TD><TD></TD></TR><TR><TD>FIRST_BCLCS_LEVEL_4</TD><TD>FIRST_BCLCS_LEVEL_4</TD><TD>Text</TD><TD>2</TD><TD>British Columbia Land Cover Classification Scheme Level 4Coded Values: TC = Treed - ConiferousTB = Treed - BroadleafTM = Treed - Mixed</TD></TR><TR><TD>MAX_PROJ_AGE_1</TD><TD>MAX_PROJ_AGE_1</TD><TD>Short</TD><TD></TD><TD>Projected Age for Leading Species</TD></TR><TR><TD>SHAPE.AREA</TD><TD></TD><TD>Double</TD><TD></TD><TD>Area auto calculated by database (m2)</TD></TR><TR><TD>SHAPE.LEN</TD><TD></TD><TD>Double</TD><TD></TD><TD>Polygon perimeter auto calculated by database (m)</TD></TR></TBODY></TABLE>Renewal Triggers and Service Levels<OL STYLE="margin:0 0 0 0;padding:0 0 0 0;"><LI> As Needed</LI></OL>References1 Holt R.F, Myers D. “OLD FOREST CURRENT CONDITION: A CUMULATIVE EFFECTS ANALYSIS FOR THE NORTHEAST RSEA STUDY AREA – Final Report”.

The Regulator provides this data "as is" with the understanding that it is not guaranteed to be accurate, correct or complete and conclusions drawn from such information are the responsibility of the user. It carries no guarantee of any kind, express or implied.The source data received from the contractor dated 2020-12-16 were extensively reviewed by GeoBC Geospatial Services and the BC-ER GIS team, through multiple platforms (FME, ArcGIS 10.8, ArcGIS Pro, Q) and concluded that these source files are corrupt beyond restoration. The contractor also supplied KMZ files; the BC-ER was able to convert 307 tiled KMZ files to reverse engineer into a Geodatabase, this was then also converted to shapefile format which was published on 2023-08-22. The considerations in this data manipulation are that there will be slight area and location variations when converting from a geographic coordinate system (globe) to a projected coordinate system (flat) - (GCS_North_American_1983 to NAD_1983_BC_Environment_Albers). The contractor provided the original shapefiles on 2023-08-28 that were verified to be valid and were used to update the originally published data on 2023-08-29.The team was also unable to confirm methods and input datasets; the assumption is that the <A href="https://catalogue.data.gov.bc.ca/dataset/vri-historical-vegetation-resource-inventory-2002-2021-" STYLE="text-decoration:underline;">VRI</A> used is 2016 vintage and did not include TFL (Tree Farm License) information, which could impact Old Forest calculations.
