"description":"This dataset provides a per-rural-municipality summary of continuously cropped European corn borer (ECB) damage-susceptible crop production across Alberta. For each municipality it reports the total 2024 cropland area and, for four crop groupings, the persistent-host area in hectares and that area as a percentage of the municipality's 2024 cropland. The four groupings are: corn only; economic-damage crops excluding wheat; economic-damage crops including wheat; and all ECB host crops. For every grouping, a cell is treated as persistent where it was cropped to that group in at least 5 of the 10 years from 2015 to 2024, as recorded in the AAFC Annual Crop Inventory (ACI, 30 m).All processing was performed in NAD83 10TM AEP Forest (WKID 3400). Note values describe crop prevalence, the share of a municipality's cropland in continuous susceptible-crop production, not infestation levels or observed crop loss, and are best read as relative ECB pressure potential. Because the numerator spans the full ten-year persistence window while the denominator is 2024 cropland only, a percentage can in principle exceed 100 where the persistent-host footprint is larger than the area classified as cropland in 2024 (for example, land that was in susceptible crops for several years but is fallow, pasture, or otherwise reclassified by 2024).Bt corn adoption means actual ECB pressure from corn fields may be lower than historical cropping patterns suggest. However, several factors sustain ECB populations even in Bt corn landscapes: non-Bt refuge blocks (required by regulation at approximately 20% of a Bt corn planting) continue to produce ECB moths that contribute to the local population; ECB surviving on or moving from Bt corn fields can still colonize adjacent non-corn hosts such as potatoes, beans, and hemp, where Bt provides no protection; and Bt corn fields continue to function as egg-laying habitat even where larval survival is reduced. Documented resistance to Bt traits in some ECB populations means Bt efficacy is no longer guaranteed in all contexts.ACI codes used in this analysisThe first value is the ACI code, followed by the ACI crop description, then the corresponding crop listed in the Prairie Pest Monitoring Network (2022) ECB host assessment.Known ECB economic-damage crops147: Corn (grain / silage / seed / sweet / specialty) \u2014 Corn 145: Wheat, winter \u2014 Winter wheat 146: Wheat, spring \u2014 Spring wheat 167: Beans, dry edible / snap or green \u2014 Beans 177: Potato \u2014 Potato 176: Tomato \u2014 Tomato 143: Quinoa \u2014 Quinoa 135: Millet \u2014 Millet 142: Sorghum / broomcorn \u2014 Sorghum 191: Hops \u2014 Hops 197: Cannabis / hemp \u2014 Cannabis / hemp 188: Apples \u2014 OrchardsOther crop hosts133: Barley \u2014 Barley 136: Oats \u2014 Oats 158: Soybean \u2014 Soybean 157: Sunflower \u2014 Sunflower 195: Buckwheat \u2014 Buckwheat 178: Beet \u2014 Sugarbeets 188 / 189: Peach \u2014 Orchards / Other fruitsCropland denominatorCropland is the sum of all pixels coded as broad agriculture (120 undifferentiated; 121 cropland), in-rotation states (130 too-wet-to-seed; 131 fallow), or any specific cultivated crop across cereals, the wheat group, oilseeds, pulses, vegetables, fruits/orchards, and specialty crops (across the 132\u2013199 ranges), while grassland (110) and pasture/forage (122) are excluded.ReferencesPrairie Pest Monitoring Network.
