The Chungnam Agricultural Research Institute is promoting the spread of nectar plants to create bee habitats. Nectar plants provide honey and pollen to pollinating insects and have positive functions such as increasing honey production, maintaining biodiversity, and restoring ecosystems. The importance of nectar plants has grown due to the recent sharp decline in bee populations. The Chungnam Agricultural Research Institute plans to investigate bee pollination activities for nectar plants such as cherry trees, sumac trees, and hovenia trees. Based on this, they will promote the spread and publicity of nectar plants. Jo Hyo-ryeo, a researcher at the Chungnam Agricultural Research Institute's Insect Industry Research Center, stated that "nectar plants are important for improving bee immunity and helping honey collection."
