Cattle foraging on milkweed: Intra‐seasonal herbivory shifts and implications for monarch butterfly conservation

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Managing milkweed (Asclepias spp.) is of high conservation concern due to its association with monarch butterflies (Danaus plexippus L.), which are proposed for listing under the Endangered Species Act. To counteract monarch declines, conservation goals aim to establish ≥1.6 billion nonagricultural milkweed stems within the Midwestern United ...
