The dataset reports percentage disturbance at the OGMA level and identifies those areas that exceed the designated managed development allowance as High-Risk Status. This information supports consideration of OGMA in decision making under the Environmental Protection and Management Regulation. Field validation of this data is encouraged in development planning. The OGMA Annual Status dataset was initially developed by the BC Energy Regulator for consideration of Managed Development Allowance across OGMA in Northeast BC. Data was derived from the provincial Old Growth Management Areas dataset. Disturbance is estimated using the BCER Surface Land Use data that is updated annually. The Managed Development Allowance allows for 10% disturbance in OGMA that are less than 100ha, and 5% or 10 hectares, whichever is greater, in OGMAs that are greater than 100ha.Data PropertiesAttributes / Column NameField AliasData TypeData PrecisionCommentsOBJECTIDObject IDObject IDUnique row number auto generated by databaseSHAPEShapeGeometry (Polygon)TSA_NUMBERTSA NumberText30Timber Supply Area NumberTSA_NUMBER_DESCRIPTIONTSA DescriptionText120Timber Supply Area for British Columbia.
