Correction: Milkweed and floral resource availability for monarch butterflies (Danaus plexippus) in the United States

Corrigendum on: Lukens L, Thieme J and Thogmartin WE (2024) Milkweed and floral resource availability for monarch butterflies (Danaus plexippus) in the United States. Front. Ecol. Evol. 12:1330583. doi: 10.3389/fevo.2024.1330583 In the original article, Discussion Section 4.2: Site Type contained errors regarding modeled milkweed densities for developed, rights-of-way, and unclassified grassland sites. The corrected sentences are as follows:Paragraph 1: Both densities are substantially lower than our model estimates of 777 plants per hectare for random sites in the North and 634 in the South. Our model estimates more closely resemble their two highest land use type means for enhanced sites in Chicago.Paragraph 3: Model predictions of densities on northern random and non-random Rights-of-Way ranged from 1,425-2,165 plants per hectare (respectively), greater than the 508 plants per hectare reported for Asclepias syriaca on Minnesota roadsides (Kasten et al., 2016). Kaul and Wilsey (2019) reported a similar mean density on Iowa roadsides (1,274 plants/hectare), but their mean included Asclepias verticillata in density calculations, which, as our data indicate (Supplementary Table S1), tends to grow in very high densities. The authors apologize for these errors and state that they do not change the scientific conclusions of the article. We thank S. Choy (U.S. Fish & Wildlife Service) for bringing this matter to our attention. The original article has been updated.
