Forest Abiotic Damage Event Coordinate system: 4269 - "NAD83" Abstract: Revision Note: Please note that this dataset has been revised and is available from the Land Information Ontario (LIO) Warehouse. An Abiotic Damage Event is where a non-biological event, such as wind or an ice storm, has damaged areas of forested land. Supplementary look-up table descriptions are available in the Data Description document, which is available for download from the additional documentation section.

  Purpose:

  The main use of the information stored in this data class will be to: - Externally calculate gross Timber Volume loss estimates caused by these events, - Monitoring the subsequent extent of damage for forest fire prevention purposes (OMNR's Fire Program), - Generate summary maps for these events at a general or provincial scale, - Storing forest abiotic damage event history in one standardized layer that is readily accessible via NRVIS and LIO.

  Supplemental Information:

  This layer is maintained by the Forest Health and Silviculture Section of the Ontario Ministry of Natural Resources (OMNR) under the auspices of the Forest Health Program - a cooperative venture between the OMNR and Natural Resources Canada (NRCAN). Legislated or Legal Authority for Collection: Forest information Manual (FIM) deliverable to Forest Industry on an annual basis. Additional Time Period Information: Abiotic Damage event information is collected on an annual basis. The depicted information reflects reported abiotic damage events that have taken place for a given year. This data class accommodates history, holding abiotic events spanning several years. Data is collected on an on-going basis, therefore the time period 'end date' may be more recent than indicated above. Changes made as needed, usually on an annual basis (mid-winter).
