Good morning, everyone. Today we're going to look at how urban beekeeping affects local ecosystems. A recent study in London monitored bee colonies on rooftops for two years. The researchers found that the bees' foraging range extended up to three kilometers from their hives. Interestingly, the most visited flower species were not native plants, but ornamental ones like lavender and rosemary. However, the study noted a potential problem: high bee density in parks could reduce pollen availability for wild insects. Therefore, the scientists suggest that urban beekeepers should coordinate with local councils to plant more diverse flora and limit hive numbers in small green areas.
