Forest Insect 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. This dataset represents events where forest insect pests have damaged trees by defoliation, foliage mining and wood boring, or contributed to tree mortality. Only the outer perimeter of the damage events are generally mapped e.g. there is no distinction between smaller areas within that were unaffected. In addition to infestations, forest mortality areas caused by these insect pests are mapped as separate events. Supplementary look-up table descriptions are available in the Data Description document, which is available for download from the additional documentation section. This layer is part of what was known as the OMNR Non-Fundamental Dataset. Additional Metadata: http://www.mnr.gov.on.ca/en/Business/Forests/2ColumnSubPage/STEL02_166920.html

  Purpose:

  Intended Use: 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 data Warehouse.

  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: Insect pest damage events are collected annually and stored as such. (by year). In NRVIS, the documented damage events are appended to this data class on an annual basis. In other words, this Data Class accommodates several years worth of forest insect damage events, with updates added on an annual basis. Data is collected on an on-going basis therefore the time period 'end date' may be more recent than indicated above.

  Federal Government and NRVIS: Main source for the damage event perimeters stored in NRVIS. Damage events are mapped every year. Mapped insect damage events are digitized by NRCAN staff as a separate ARCINFO coverage by year, insect agent, and mortality indicator for moderate-severe damage areas. the covers are passed on to the Forest Management Branch, which are in-turn eventually imported into NRVIS. Event data collected in the field by Forest Health Technicians/Technologists on an annual basis.
