Forest Health Survey 2023 [Minnesota]
Description
This dataset shows where largescale tree canopy damage was delineated in aerial surveys in 2023. Only forest disturbances were mapped if they were occurring at the time of the flight. Flights occurred from May to August. The following were the most common disturbers, listed from largest area disturbed to smallest area disturbed: spruce budworm, eastern larch beetle, larch casebearer, snow damage from the mid-December 2022 storm, and emerald ash borer. Several other disturbance agents are not listed. Not included in this dataset are unmapped areas of damage from emerald ash borer in the Twin Cities Metro area and north of the Metro, oak wilt, Armillaria root disease in all tree species, black ash decline, northern hardwood decline, minor defoliation, and other difficult-to-aerially-map tree health problems., 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)., May 3 through August 4, 2023 time period in which polygons were surveyed aerially
