Title:

Forest Health Survey 2021 [Minnesota]

Description:

This dataset shows where largescale tree canopy damage was delineated in aerial surveys in 2021. Only forest disturbances were mapped if they were occurring at the time of the flight. Flights occurred sporadically from mid June to early September. The following were the most common disturbers, listed from largest area disturbed to smallest area disturbed: spruce budworm, eastern larch beetle, aspen decline, larch casebearer, forest tent caterpillar, emerald ash borer, flooding, wind, pine bark beetles, and twolined chestnut borer. Not included in this dataset are unknown causes of light mortality, discoloration (without notes), or defoliation; fire; and oak wilt. 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). 20210622-20210918 time period in which polygons were surveyed aerially
