Forest Health Survey 2018 [Minnesota]
Description
This dataset shows where largescale tree canopy damage was delineated in aerial surveys in 2018. Forests in northern and central Minnesota were surveyed except northwestern St. Louis County and most of Koochiching County. Forests in Goodhue, Wabasha, Olmsted, Winona, Fillmore, and Houston counties were also surveyed. Only forest disturbances were mapped if they were occurring at the time of the flight. Oak wilt was not assessed. Flights occurred sporadically from early June to mid-October. The following were the most common disturbers, listed from largest area disturbed to smallest area disturbed: spruce budworm, eastern larch beetle, forest tent caterpillar, larch casebearer, abiotic cause of aspen decline, arborvitae leafminer, flooding, wind, emerald ash borer, twolined chestnut borer, heavy seed production on red maples, fire, bark beetles on pine, and jack pine budworm. Not included in this dataset are unknown causes of damage., 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 is available through the Forest Health unit of the MNDNR)., 20180608-20181015 time period in which polygons were surveyed aerially
