Understanding weed dynamics is essential for maintaining crop productivity, as weed communities continuously shift in response to climate change, cropping systems, and management practices. The present study investigated weed flora across major agricultural ecosystems in Gangwon Province from 2021 to 2025 to characterize their dominant species and community structure. Surveys were conducted thrice annually in 48 upland fields, orchards, paddy fields, and greenhouses. Species were identified based on the National List of Species of Korea, and importance values (IVs) were calculated using the relative frequency and cover derived from the Braun–Blanquet scores. A total of 219 taxa were recorded, with orchards and uplands exhibiting the highest richness, whereas paddy fields showed simplified hydrophytic assemblages. Artemisia indica, Digitaria ciliaris, and Echinochloa crus-galli were consistently dominant across ecosystems, whereas aquatic species such as Lemna perpusilla were characteristic of paddy fields. Collectively, these findings provide baseline information for regional weed monitoring and development of site-specific management strategies.
