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.
