(1) - Diseases other than foliage diseases are very difficult to accurately map using aerial overview style surveys. The totals presented here are not an accurate depiction of dwarf mistletoe and root disease incidence in the province. More accurate data is obtained using ground surveys.

As in previous years, nearly all of the province was surveyed with the exceptions of portions of the Mid-Coast, Cassiar and Sunshine Coast due to weather and resource constraints.

(2) Fire data was collected by the overview survey and augmented, where available, with data provided by MOFR Protection Branch.
