Title:

Forest Health Survey 2022 [Minnesota]

Description:

This dataset shows where largescale tree canopy damage was delineated in aerial surveys in 2022. Only forest disturbances were mapped if they were occurring at the time of the flight. Flights occurred sporadically from early June to mid September. The following were the most common disturbers, listed from largest area disturbed to smallest area disturbed: spruce budworm, eastern larch beetle, aspen decline, unknown cause of defoliation on hardwoods and aspen, wind, forest tent caterpillar, oak wilt, flooding, unknown causes of mortality, large aspen tortrix, bark beetles on pine, larch casebearer, and twolined chestnut borer. Not included in this dataset are unmapped areas of damage from emerald ash borer in the north metro area, forest damage in southeast Minnesota, and most twolined chestnut borer-infested forests. The purpose of this survey was to indicate where significant and highly noticeable tree damage occurred. Another purpose of this survey was to monitor general trends in forest health conditions (previous years’ aerial survey data are available through the Forest Health unit of the MNDNR). 20220604-20220914 time period in which polygons were surveyed aerially
